How to Get a General Contractor License in Illinois: Complete 2026 Guide

The Truth About General Contractor Licensing in Illinois: No State License, Big Local Impact

Alright, let’s cut straight to it. You’re looking to get your General Contractor (GC) license in Illinois, and the first thing you need to understand is this: Illinois does not issue a statewide General Contractor license. Read that again. It’s a fundamental truth that trips up a lot of folks coming into this state, especially those from places with centralized licensing boards.

What does this mean for you? It means that licensing for general contractors is handled at the local level – city by city, county by county. If you plan to build in Chicago, you need a Chicago General Contractor license. If you’re building in Naperville, you’ll deal with Naperville’s local building department. This decentralized approach is critical to grasp from day one.

Now, while there’s no statewide GC license, don’t confuse that with all contractor licensing. The Illinois Department of Financial and Professional Regulation (IDFPR) does regulate specific trades statewide. Think electricians, plumbers, roofers, and asbestos abatement contractors. For example, if you’re specifically a roofing contractor operating anywhere in Illinois, you must be licensed by the IDFPR. But for general contracting, the buck stops with the local municipality where your project is located.

Why does this matter so much? Because it means your “Illinois GC license” journey isn’t a single application to a state agency in Springfield. It’s a strategic decision about where you intend to operate and then a targeted effort to meet those specific local requirements. Given Illinois’s population and economic activity, the City of Chicago dominates the construction market, and its licensing requirements are by far the most comprehensive and complex in the state. For most serious general contractors in Illinois, getting licensed in Chicago is a rite of passage and a necessity.

This guide will focus heavily on the City of Chicago’s General Contractor licensing process because it represents the pinnacle of local licensing in Illinois and sets a high bar that often covers many requirements found in smaller municipalities. However, always remember: always check with the specific city or county building department where your project is located before you break ground. Ignoring local requirements is a surefire way to run into costly delays, fines, or even project shutdowns.

Navigating the Chicago General Contractor License: Your Primary Illinois Challenge

If you’re serious about general contracting in Illinois, especially in the lucrative commercial and large-scale residential sectors, then the City of Chicago General Contractor license isn’t just an option – it’s practically a mandate. Chicago is the economic engine of Illinois, and its construction market is robust, diverse, and constantly evolving. This isn’t just about building skyscrapers; it’s about renovating historic brownstones, developing new mixed-use properties, and contributing to significant infrastructure improvements.

The City of Chicago’s Department of Buildings (DOB) is the agency responsible for issuing these licenses. Unlike many other cities that might have a single, generic contractor license, Chicago takes it a step further with a tiered system. This system is designed to match your license to the scope and complexity of the work you intend to perform, ensuring that contractors have the appropriate experience and qualifications for the projects they undertake.

Understanding this tiered system is your first critical step. Chicago offers several classes of General Contractor licenses, each with different privileges, requirements, and associated fees:

Class A General Contractor: This is the big league. A Class A license allows you to perform general contracting work on any building, regardless of height or area. This is for the contractors tackling high-rises, large commercial complexes, and significant public works projects. The requirements for this class are the most stringent, reflecting the immense responsibility involved.
Class B General Contractor: This license permits general contracting on buildings up to four stories in height and 80,000 square feet in area. It’s suitable for mid-rise commercial buildings, multi-unit residential buildings, and many suburban-style office parks within city limits.
Class C General Contractor: For projects up to three stories in height and 30,000 square feet in area. This class covers a broad range of work, including many smaller commercial renovations, townhomes, and multi-flat residential buildings.
Class D General Contractor: This is generally for one- or two-story buildings, limited to 15,000 square feet in area. This often covers single-family homes, small commercial build-outs, and accessory structures.

The Class A, B, and C licenses are typically what people refer to when they talk about a “Chicago GC license.” The Class D is more restrictive but still valuable for smaller-scale operations. It’s imperative that you accurately assess the type of work you intend to pursue in Chicago and apply for the appropriate class. Trying to operate above your license class is a quick way to get shut down and face hefty penalties.

The complexity of Chicago’s licensing process reflects the city’s commitment to safety, quality, and accountability in its built environment. While it might seem daunting, successfully navigating this process proves your capability and opens the door to immense opportunities in one of the nation’s most dynamic construction markets.

Step-by-Step: Applying for a General Contractor License in Chicago (and What to Expect Elsewhere)

Since Chicago represents the most comprehensive licensing challenge in Illinois, we’ll walk through its process in detail. Remember, even if you don’t plan to work in Chicago immediately, understanding its requirements provides an excellent framework for what other, often simpler, municipalities might ask for.

A. Choose Your License Class

As discussed, your first move is to determine which Chicago General Contractor license class (A, B, C, or D) aligns with your business goals. This choice will dictate your experience requirements, insurance minimums, and the scope of projects you can undertake. Don’t over-license yourself if you’re starting small, but also don’t under-license and limit your potential. Be realistic and strategic.

B. Form Your Business Entity in Illinois

Before you even think about submitting a license application to the City of Chicago, you need a legitimate business entity registered with the State of Illinois. This is handled by the Illinois Secretary of State (SOS), located in Springfield.

Choose Your Structure: Most contractors opt for a Limited Liability Company (LLC) or a Corporation (S-Corp or C-Corp). Each has different implications for liability, taxation, and administrative burden. Consult with a business attorney and accountant licensed in Illinois to determine the best fit for your specific situation.
File with the SOS: You’ll file Articles of Organization (for an LLC) or Articles of Incorporation (for a Corporation) with the Illinois SOS. This officially registers your business name and structure in the state. You can do this online through the SOS website.
Obtain an EIN: Once your business is registered with the SOS, you’ll need an Employer Identification Number (EIN) from the IRS, even if you don’t plan to hire employees immediately. This is your business’s federal tax ID.
Registered Agent: Illinois law requires all registered businesses to have a Registered Agent with a physical address in Illinois (not a P.O. Box). This agent receives official correspondence and legal documents on behalf of your business. This can be you, an employee, or a professional registered agent service.

C. Secure Illinois-Specific Insurance and Bonds

This isn’t just a good idea; it’s a non-negotiable requirement for operating as a GC in Illinois, especially in Chicago.

Workers’ Compensation Insurance: If you have even one employee (including yourself if you’re structured as an employee of your own corporation), Illinois law mandates Workers’ Compensation insurance. This is overseen by the Illinois Workers’ Compensation Commission. Failure to carry this is a serious offense with severe penalties. Ensure your policy meets state minimums and covers all your employees.
Commercial General Liability (CGL) Insurance: The City of Chicago has specific CGL requirements for its GC licenses. For Class A, B, and C licenses, you’ll typically need a minimum of $1,000,000 per occurrence and $2,000,000 aggregate coverage. The policy must also name the City of Chicago as an additional insured. Your insurance broker, ideally one experienced with Illinois construction companies, will know these specifics.
Surety Bonds: Depending on your license class and the type of work, Chicago may require a surety bond. For example, Class A GCs often need a significant bond. This bond acts as a financial guarantee that you will complete your projects according to contract and code. The exact bond amount will be specified by the DOB during the application process. You’ll work with a surety bond company to secure this.

D. Meet Experience and Education Requirements

Again, no statewide requirements here. Chicago, however, demands proof of competence.

Experience: The City of Chicago typically requires a certain number of years of verifiable experience in the construction industry, often with a portion of that experience at a supervisory level. For Class A, B, and C licenses, this can range from 3 to 10 years or more. You’ll need to provide detailed documentation, including:
Affidavits from licensed architects, engineers, or other licensed professionals who can attest to your experience.
A comprehensive list of projects you’ve worked on, detailing your role, the scope of work, and approximate costs.
Resumes, letters of recommendation, and potentially even tax records or pay stubs to verify employment history.
Education: While a formal degree in construction management or engineering can be beneficial and may count towards some experience requirements, it’s generally not a strict substitute for practical, hands-on experience for Chicago’s GC licenses.

E. Pass the Chicago Contractor Exam (If Required)

The City of Chicago requires the qualifying individual for Class A, B, and C General Contractor licenses to pass a competency exam. This exam is typically administered by a third-party testing agency approved by the DOB.

Exam Content: The exam focuses on a broad range of knowledge critical to general contracting, including:
Chicago Building Code (including zoning, structural, fire, and life safety codes).
Construction safety (OSHA standards, specific Chicago safety regulations).
Construction management principles (project planning, scheduling, cost control).
Contract law and lien laws relevant to Illinois.
Basic construction methods and materials.
Qualifying Individual: Note that it’s not necessarily every owner who needs to take the exam. It’s the “qualifying individual” – someone within the company who possesses the necessary knowledge and experience and will be responsible for the company’s compliance with building codes and regulations. This individual must be an officer, owner, or managing employee of the applicant company.

F. Complete and Submit Your Chicago Application

Once you’ve gathered all your documents, secured insurance and bonds, and passed the exam (if required), you’ll meticulously complete the City of Chicago General Contractor license application.

Online Portal: The City of Chicago generally uses an online licensing portal for applications. Be prepared to upload digital copies of all supporting documents.
Document Checklist: The application will include a comprehensive checklist. This isn’t a suggestion; it’s a requirement. Missing documents or incomplete information will lead to delays or outright rejection. Double-check everything.
Fees: Be prepared to pay the non-refundable application fee at the time of submission.

G. Handle Local Licenses Outside Chicago

Even if Chicago is your primary target, you might work in other Illinois municipalities. While their processes are generally simpler, don’t skip this step.

Research Each Municipality: Every city and even some counties will have its own building department and potentially its own contractor registration or licensing requirements.
Typical Requirements: These often include:
Proof of state business registration (from the Illinois SOS).
Proof of General Liability and Workers’ Compensation insurance.
A local registration fee.
Sometimes, a local bond or even a simple background check.
Example: A city like Naperville might require you to register your business, show proof of insurance, and pay a fee, but not require a local exam or extensive experience documentation like Chicago. Never assume; always call the local building department.

Illinois Contractor Exams and Prep Resources: What You Need to Know

Let’s reiterate: There is no statewide General Contractor exam in Illinois. This is a critical distinction that saves you from hunting for non-existent resources. Your primary concern regarding exams will be the City of Chicago General Contractor Exam if you’re pursuing a Class A, B, or C license.

The Chicago Contractor Exam is designed to ensure that the qualifying individual has a thorough understanding of construction principles, safety regulations, and, most importantly, the Chicago Building Code. It’s not a walk in the park; it requires dedicated study.

Who Takes It: The qualifying individual for the applying company (an owner, officer, or managing employee) must pass the exam.
Content Areas:
Chicago Building Code: This is paramount. You’ll need to be familiar with the city’s specific adopted codes, which are largely based on the International Code Council (ICC) family of codes (International Building Code, International Residential Code, etc.) but with local amendments. This includes structural provisions, fire safety, accessibility, electrical, plumbing, and mechanical systems.
Construction Safety: OSHA regulations are fundamental, but Chicago might have specific safety ordinances.
Construction Management: Project planning, estimating, scheduling, contract administration, and site supervision.
Illinois Law: Basic understanding of Illinois lien laws, contract law, and other statutes relevant to construction.
Prep Resources:
Code Books: Obtain the relevant editions of the Chicago Building Code. These are your primary study materials. You can often find them through the City of Chicago’s website or through ICC.
ICC Resources: Since Chicago’s codes are based on ICC, studying ICC practice exams and guides for general building contractor exams can be very helpful, but always cross-reference with Chicago’s specific amendments.
Trade Associations: Local chapters of construction trade associations, like the Associated General Contractors of Illinois (AGC of Illinois) or the Chicagoland Associated General Contractors (CAGC), may offer or recommend exam prep courses or study groups.
Online Exam Prep: Several online platforms offer contractor exam prep courses. Look for those specifically tailored to ICC codes and, if possible, mention Chicago-specific content. Always vet these providers for their reputation and success rates.
Local Community Colleges/Universities: Some Illinois community colleges or universities with construction management programs might offer continuing education courses that aid in exam preparation, though direct “Chicago GC exam prep” courses might be less common.

Success on this exam hinges on your ability to not just memorize facts but to understand how to apply building codes and construction principles in real-world scenarios within the Chicago context.

Experience and Education: Proving Your Prowess in Illinois

As with licensing itself, experience and education requirements for general contractors in Illinois are entirely localized. The State of Illinois doesn’t dictate a minimum number of years or a specific degree for you to hang your shingle as a GC. However, for a serious operator, especially in a market like Chicago, demonstrating substantial experience is non-negotiable.

For Chicago General Contractor Licenses (Class A, B, C):

The City of Chicago places a heavy emphasis on verifiable, relevant experience. This is how they ensure that licensed GCs possess the practical knowledge and leadership skills necessary to manage complex construction projects safely and effectively.

Years of Experience:
Class A: Expect to need a significant amount, often 10 years or more, with a substantial portion in a supervisory or project management role on large, complex projects.
Class B & C: Typically 5-7 years of experience, with a good portion in a supervisory capacity, on projects relevant to the scope of these license classes.
Documentation is Key: Chicago’s Department of Buildings will scrutinize your experience. You’ll need to provide:
Detailed Project Lists: For each project, include the location, type of construction (new build, renovation, commercial, residential), your specific role (e.g., Superintendent, Project Manager, Foreman), the approximate project value, and the start/completion dates. Be ready to provide contact information for references on these projects.
Affidavits: Often, the DOB requires affidavits from licensed professionals (Illinois-licensed architects, structural engineers, or even other licensed general contractors) who can attest to your experience, competence, and the nature of the projects you’ve managed. These affidavits must be notarized.
Resumes/CVs: A comprehensive resume detailing your professional history in construction.
Letters of Recommendation: From previous employers, clients, or industry peers.
Proof of Employment: Pay stubs, W-2s, or tax returns to verify periods of employment in construction.
Education’s Role: While not a strict substitute for practical experience, a formal education in construction management, civil engineering, architecture, or a related field from an accredited institution in Illinois or elsewhere can be highly beneficial.
It can sometimes reduce the required years of practical experience.
It demonstrates a foundational understanding of construction theory, codes, and project management principles.
Always submit transcripts or diplomas if you have relevant degrees.

For Other Illinois Municipalities:

Outside of Chicago, the experience requirements are generally much less stringent, if they exist at all. Many smaller towns and cities may simply ask for a resume or a declaration of experience on their application form, without requiring extensive documentation or third-party verification. However, some larger suburban cities might have their own specific, albeit typically less rigorous, requirements.

The “Qualifying Individual”:

For Chicago and other municipalities that do have experience requirements, it’s often about the “qualifying individual” within your company. This person is the one whose experience and knowledge are being assessed. They must be an owner, officer, or managing employee who holds a significant operational role and responsibility for the construction activities of the business. This ensures that the licensed entity always has a competent individual at the helm.

In essence, while Illinois gives you the freedom to start a general contracting business without statewide experience mandates, the market – particularly Chicago – demands that you prove your mettle through documented, relevant experience. Don’t underestimate the effort required to compile this documentation; it’s a significant part of the application process.

Bonds and Insurance: Protecting Your Illinois Business and Clients

In the construction world, especially in a litigious state like Illinois, proper bonding and insurance aren’t just bureaucratic hurdles; they are fundamental pillars of risk management, client protection, and business credibility. For general contractors in Illinois, understanding and securing the right coverage is non-negotiable.

Surety Bonds in Illinois

A surety bond is a three-party agreement where the surety company guarantees to the project owner (the obligee) that the contractor (the principal) will perform the contract according to its terms. If the contractor fails, the surety steps in.

Chicago Requirements: The City of Chicago often requires general contractors, particularly those holding Class A, B, or C licenses, to post a surety bond.
License Bonds: These bonds guarantee that you will operate in compliance with the city’s ordinances and regulations. The amount varies by license class, with Class A requiring a higher bond than Class B or C. For instance, a Class A license might require a bond in the tens of thousands of dollars.
Permit Bonds: For specific projects, especially those involving public way obstruction, demolition, or significant structural work, the City of Chicago may require a separate permit bond.
Public Works Projects (Statewide): If you intend to bid on public works projects in Illinois (e.g., state, county, municipal, or school district projects), you will almost certainly need performance bonds and payment bonds.
Performance Bond: Guarantees to the public entity that you will complete the project according to the contract.
Payment Bond: Guarantees that you will pay your subcontractors and suppliers. This protects the public entity from mechanic’s liens.
The Illinois Procurement Code and local government purchasing acts dictate the requirements for these bonds, often for projects exceeding a certain dollar threshold.
How to Get a Bond: You’ll work with a surety bond company or an insurance broker specializing in surety. They will assess your business’s financial health, experience, and creditworthiness to determine your bondability and premium.

Insurance Requirements in Illinois

Insurance protects your business from financial losses due to accidents, injuries, and property damage. Illinois has specific mandates and Chicago has additional requirements.

Workers’ Compensation Insurance:
Mandatory in Illinois: If you have any employees (even one), Illinois law requires you to carry Workers’ Compensation insurance. This is administered by the Illinois Workers’ Compensation Commission. This insurance covers medical expenses and lost wages for employees injured on the job, regardless of fault.
Consequences of Non-Compliance: Operating without Workers’ Comp is a serious violation in Illinois, carrying substantial fines (up to $10,000 for each day of non-compliance) and potential criminal charges. Do not skimp on this.
Commercial General Liability (CGL) Insurance:
City of Chicago Mandate: For your Chicago GC license, CGL insurance is mandatory. The City of Chicago typically requires a minimum of $1,000,000 per occurrence and $2,000,000 aggregate for Class A, B, and C licenses.
Additional Insured: Your CGL policy must specifically name the City of Chicago as an “additional insured.” This protects the city in case of a claim related to your work.
What it Covers: CGL protects your business from claims of bodily injury or property damage caused by your operations, products, or completed work.
Commercial Automobile Liability Insurance:
If your business owns or leases vehicles used for work, you must carry commercial auto insurance. This covers liabilities arising from accidents involving your business vehicles. Illinois law requires minimum liability coverage for all vehicles on the road.
Umbrella Liability Insurance:
Often recommended for contractors, an umbrella policy provides additional liability coverage above the limits of your primary CGL and auto policies. Given the high stakes in construction, this extra layer of protection can be invaluable.
Builder’s Risk Insurance:
While not typically a licensing requirement, Builder’s Risk insurance is crucial for most construction projects. It protects the structure and materials during construction from perils like fire, theft, and vandalism. Project owners or lenders often require it.
Professional Liability (E&O) Insurance:
If your company provides design-build services or offers significant input on design, professional liability insurance (Errors & Omissions) is wise. It covers claims arising from professional negligence or errors in design or advice.

Choosing an Illinois Insurance Broker:

It is highly advisable to work with an insurance broker who specializes in the Illinois construction industry. They understand the specific state laws, local municipal requirements (especially Chicago’s), and the unique risks faced by contractors in the region. They can help you tailor a comprehensive insurance and bonding package that meets all legal requirements and adequately protects your business. Don’t just get the cheapest policy; get the right policy.

Fees and Timeline: Budgeting for Your Illinois Contractor License

Getting licensed in Illinois, particularly in a major market like Chicago, involves a series of financial outlays and a variable timeline. Proper budgeting and realistic expectations regarding processing times are crucial for a smooth launch.

Fees Associated with Your Illinois GC “License”:

Since there’s no single state license fee, your costs will be a mosaic of different agency charges.

Illinois Secretary of State (SOS) Business Registration Fees:

LLC Filing: As of 2026, the fee to file Articles of Organization for an LLC in Illinois is typically around $150-$200.
Corporation Filing: Filing Articles of Incorporation for a corporation is in a similar range, often $150-$200.
Annual Report Fees: Both LLCs and corporations have annual report fees, usually around $75-$100, which must be paid to the SOS to maintain good standing.
Registered Agent Service: If you use a professional registered agent, expect to pay $100-$200 annually.

City of Chicago General Contractor License Fees (as of 2026, subject to change):

Application Fee: There’s usually a non-refundable application fee, which can range from a few hundred dollars to over a thousand, depending on the license class.
License Issuance Fee: Once approved, there’s a fee to actually issue the license. This can also vary significantly by class.
Renewal Fees: Chicago GC licenses typically need to be renewed periodically (e.g., every 1-2 years), and there are renewal fees associated with this. These can be similar to the initial issuance fees.
Exam Fees: If you need to take the Chicago Contractor Exam, the third-party testing agency will charge a fee, often in the range of $100-$200 per attempt.

Insurance and Bond Premiums:

Workers’ Compensation: Premiums vary widely based on your payroll, job classifications, and claims history. This is an ongoing cost.
Commercial General Liability: Premiums depend on your coverage limits, scope of work, claims history, and other factors. Expect this to be a significant annual expense.
Surety Bonds: The premium for a surety bond is typically a percentage (e.g., 1-3%) of the bond amount. For a $20,000 license bond, this might be $200-$600 annually.

Other Local Municipal Fees:

If you operate outside Chicago, each city or county will have its own contractor registration or permit fees, which could range from $50 to several hundred dollars annually or per project.

Professional Service Fees:

Legal Counsel: For business formation, contract review, and compliance advice.
Accounting Services: For tax planning, bookkeeping, and financial advice.
Consultants: If you hire someone to help with the application process or exam prep.

Total Initial Outlay: Expect to spend anywhere from $2,000 to $10,000+ in initial fees, premiums, and professional services just to get your Chicago GC license and associated business setup in order, not including your working capital.

Timeline for the Application Process:

This is where patience becomes a virtue. There’s no fast track, and delays are common if you’re not meticulous.

Business Entity Formation (Illinois SOS):

Online Filing: If you file online and everything is correct, the Illinois SOS can process Articles of Organization/Incorporation within 1-3 business days.
Mail Filing: Mail filings take considerably longer, often 2-4 weeks.
EIN: Obtaining an EIN from the IRS online is instant.

Gathering Documentation (Experience, Insurance, Bonds):

This is often the most time-consuming part. Collecting project lists, securing affidavits, getting insurance quotes, and obtaining bond pre-approvals can take 2-6 weeks or more, depending on how prepared you are and the responsiveness of your references and brokers.

Exam Preparation and Scheduling (Chicago):

Study Time: Depending on your existing knowledge, preparing for the Chicago Contractor Exam could take anywhere from 1 month to 3 months of dedicated study.
Scheduling: Scheduling the exam with the third-party testing agency might involve a waiting period of 1-3 weeks.
Results: Exam results are often available immediately or within a few days.

City of Chicago Application Submission and Processing:

Application Completion: Meticulously filling out the application and uploading all documents can take several days to a week.
DOB Review: Once submitted, the City of Chicago Department of Buildings will review your application. This can take anywhere from 4 weeks to 12 weeks or even longer, depending on their current workload, the completeness of your application, and whether they require additional information. Incomplete applications will be sent back, resetting your timeline.
Issuance: Once approved, your license will be issued.

Other Local Licenses:

These are usually quicker, often processed within a few days to 2 weeks, once you have your state business registration and insurance in place.

Overall Timeline: From starting your business registration with the Illinois SOS to receiving your Chicago General Contractor license, you should realistically budget 3 to 6 months. If you’re highly organized and everything goes perfectly, it might be on the shorter end. If there are delays in documentation, exam retakes, or application reviews, it could stretch longer. Plan accordingly and start early!

Illinois Reciprocity Agreements: Don’t Count on Them for GCs

This section is going to be brief and to the point because the answer is straightforward: Illinois does not have reciprocity agreements for General Contractor licenses with other states.

Why? Because, as we’ve established, Illinois does not have a statewide General Contractor license to begin with. You can’t have reciprocity for something that doesn’t exist at the state level.

What This Means for You: If you are a licensed general contractor in another state (e.g., Indiana, Wisconsin, Missouri, Florida, California), that license carries no weight for general contracting purposes in Illinois. You will need to go through the full licensing process as required by the specific municipality where you intend to work.
Chicago’s Stance: The City of Chicago requires all applicants to meet its specific experience, exam, insurance, and bond requirements, regardless of whether they hold a GC license in another jurisdiction. There are no shortcuts based on out-of-state credentials for general contracting.
Trade Licenses vs. GC Licenses: It’s important not to confuse this with specific trade licenses. The IDFPR does have some reciprocity agreements for certain trades (like plumbing or electrical) with specific states. However, this is entirely separate from general contracting. If you’re a licensed plumber in Wisconsin, you might have an easier path to an Illinois plumbing license, but that won’t help you get a Chicago General Contractor license.

So, if you’re coming to Illinois from another state with a GC license in hand, wipe the slate clean. You’re starting from scratch with the local authorities, and for serious work, that means tackling the City of Chicago’s comprehensive process. View it as an opportunity to prove your capabilities in a new market, rather than a frustrating hurdle.

Business Entity Formation in Illinois: Setting Up Your Foundation

Before you even think about swinging a hammer or pouring concrete, you need to establish a legal business entity in Illinois. This isn’t just a formality; it’s a critical step that impacts your liability, taxation, credibility, and even your ability to get local licenses and permits. All of this is handled through the Illinois Secretary of State (SOS), whose main office is in Springfield.

Choose Your Business Structure:

Sole Proprietorship: Simple to set up, but offers no personal liability protection. Your personal assets are at risk if your business incurs debt or is sued. Not recommended for most construction businesses due to inherent risks.
Partnership: Similar to sole proprietorships regarding liability for general partners. Limited partnerships or LLPs offer some protection but add complexity.
Limited Liability Company (LLC): This is a popular choice for contractors.
Pros: Offers personal liability protection (separates your personal assets from business debts and lawsuits), flexible taxation (can be taxed as a sole proprietorship, partnership, or even an S-Corp), and less administrative burden than a corporation.
Cons: Can be perceived as less “professional” than a corporation by some larger clients, though this perception is fading.
Corporation (S-Corp or C-Corp):
Pros: Strongest personal liability protection, often perceived as more credible by large clients and lenders, and can offer tax advantages for certain income levels (S-Corp avoids double taxation).
Cons: More complex to set up and maintain (requires bylaws, board meetings, minutes, etc.), and C-Corps face double taxation (corporate profits taxed, then dividends taxed to shareholders).
Why it Matters for Licensing: Many municipalities, especially Chicago, require you to be a legally registered business entity (LLC or Corporation) to apply for a contractor license.

Register with the Illinois Secretary of State (SOS):

Name Availability: Before filing, check if your desired business name is available through the Illinois SOS website. You don’t want to get rejected for a name conflict.
File Articles of Organization (LLC) or Articles of Incorporation (Corporation): You’ll submit these documents to the Illinois SOS. They formally create your business entity in the state. This can be done online for faster processing.
Registered Agent: Illinois law requires every registered business entity to have a Registered Agent with a physical street address in Illinois (not a P.O. Box). This agent’s role is to receive official legal and tax documents. You can be your own registered agent if you meet the requirements, or you can hire a professional service.
Operating Agreement (LLC) or Bylaws (Corporation): While not filed with the SOS, these internal documents are crucial. An LLC Operating Agreement outlines ownership, management, and profit distribution. Corporate Bylaws govern the internal management of the corporation. Have an Illinois business attorney draft these.

Obtain an Employer Identification Number (EIN) from the IRS:

After your business entity is registered with the Illinois SOS, you’ll need an EIN from the IRS. This is your business’s federal tax ID number, similar to a Social Security number for an individual. You need an EIN even if you don’t plan to hire employees immediately, especially if you’re an LLC or Corporation. You can apply for this instantly online through the IRS website.

Other State Business Registrations/Permits:

Illinois Department of Revenue (IDOR): You’ll need to register with the IDOR for state tax purposes, including sales tax (if you sell taxable goods), withholding tax (if you have employees), and potentially other business taxes.
Unemployment Insurance: If you have employees, you’ll need to register with the Illinois Department of Employment Security (IDES) for unemployment insurance.
Local Business Licenses: Beyond contractor licenses, some municipalities in Illinois might require a general business license to operate within their jurisdiction. Check with the city clerk or local chamber of commerce.

Consult Professionals: This is not an area to cut corners. Consult with an Illinois-licensed business attorney and a Certified Public Accountant (CPA) experienced with construction businesses. They can guide you through choosing the optimal business structure, ensure all filings are correct with the Illinois SOS and IDOR, and help you understand your ongoing compliance obligations. Getting this right from the start lays a solid, legally sound foundation for your general contracting business in Illinois.

Illinois Workers’ Comp and Liability Insurance Minimums: The Essentials

When operating a general contracting business in Illinois, securing the correct insurance coverage isn’t just a suggestion; it’s a legal and contractual imperative. Failing to meet these requirements can lead to severe penalties, financial ruin, and the inability to obtain or maintain your local contractor licenses.

Illinois Workers’ Compensation Insurance

This is non-negotiable for virtually any business with employees in Illinois.

Mandatory Requirement: The Illinois Workers’ Compensation Act mandates that nearly all employers in Illinois carry Workers’ Compensation insurance. This includes general contractors, regardless of the size of their operation.
Who is Covered: This insurance covers medical expenses, lost wages, and rehabilitation costs for employees who suffer work-related injuries or illnesses. It also provides death benefits to dependents in tragic cases.
Independent Contractors vs. Employees: Be extremely careful about misclassifying workers as “independent contractors” to avoid Workers’ Comp premiums. The Illinois Workers’ Compensation Commission has strict criteria for determining employee status, and misclassification can lead to hefty fines, back premiums, and legal action. When in doubt, err on the side of caution or seek legal advice.
Administration: The Illinois Workers’ Compensation Commission (IWCC) is the state agency responsible for administering the Workers’ Compensation Act. They oversee claims, resolve disputes, and ensure employer compliance.
Minimums: There aren’t specific “minimum” dollar amounts set by the state for Workers’ Comp in the same way as liability insurance. Instead, your policy must provide full coverage for all statutory benefits as defined by the Illinois Workers’ Compensation Act. Premiums are calculated based on your payroll, the classification of your employees’ jobs (which reflects risk), and your company’s claims history (experience modification rating or “mod rate”).
Consequences of Non-Compliance: Operating without Workers’ Comp insurance in Illinois is a serious criminal offense. Penalties include:
Fines of up to $10,000 for each day of non-compliance, with a minimum fine of $1,000.
Potential criminal charges, including a Class A misdemeanor for the first offense and a Class 4 felony for subsequent offenses.
Personal liability for company officers if the company fails to pay benefits.
Inability to obtain permits or licenses from local municipalities, including Chicago.

Commercial General Liability (CGL) Insurance

While not universally mandated by the State of Illinois for all businesses, CGL is absolutely essential for general contractors and is a strict requirement for local licensing, especially in Chicago.

City of Chicago Minimums: For a General Contractor license in the City of Chicago (Class A, B, C), you will typically need:
$1,000,000 per occurrence: This is the maximum amount the policy will pay for any single incident.
$2,000,000 aggregate: This is the maximum amount the policy will pay out over the entire policy period, regardless of the number of occurrences.
Additional Insured: Your CGL policy must name the City of Chicago as an “additional insured.” This is a standard requirement to protect the city from liability arising from your operations.
What CGL Covers: CGL insurance protects your business from claims of:
Bodily Injury: Injuries sustained by third parties (e.g., a passerby tripping over your equipment, a client falling on your job site).
Property Damage: Damage to third-party property (e.g., accidentally damaging a neighboring building, breaking a client’s window).
Personal and Advertising Injury: Claims like libel, slander, or copyright infringement.
Products-Completed Operations: Crucially for contractors, this covers liability for injuries or damages that occur after your work is completed and accepted (e.g., a faulty installation causing a leak months later).
Other Municipalities: While Chicago’s requirements are the most stringent, almost all other municipalities in Illinois that require contractor registration will ask for proof of CGL insurance, often with similar minimum limits, though sometimes slightly lower for smaller projects.

Key Takeaway: Do not view insurance as a burden. It is your shield. Work with an experienced Illinois-licensed insurance broker who understands the construction industry and specific municipal requirements. They can help you navigate the complexities, ensure you meet all legal and licensing obligations, and build a robust insurance program that truly protects your business from the inherent risks of construction in Illinois.

Common Mistakes Illinois Applicants Make: Learn from Others

Navigating the Illinois licensing landscape, especially with its decentralized nature, can be a minefield for the unprepared. Here are the most common pitfalls Illinois General Contractor applicants fall into, and how you can avoid them:

Assuming a Statewide GC License Exists:

The Mistake: This is the #1 error. Contractors from other states often waste time searching for an “Illinois State GC License” application or trying to find reciprocity.
The Fix: Understand from day one: there is NO statewide GC license. Licensing is local. Focus your efforts on the specific municipality where you intend to work (most likely Chicago initially).

Underestimating Chicago’s Complexity:

The Mistake: Many new applicants, even experienced GCs from outside Illinois, are caught off guard by the detailed requirements for a City of Chicago GC license (tiered classes, extensive documentation, specific exam, high insurance/bond minimums).
The Fix: Treat the Chicago application as a major project itself. Dedicate significant time to understanding each requirement, gathering documentation, and preparing for the exam. Don’t rush it.

Failing to Secure Adequate Insurance and Bonds Specific to Chicago:

The Mistake: Providing generic CGL insurance certificates or insufficient bond amounts that don’t meet Chicago’s specific “additional insured” wording or dollar thresholds. Also, trying to operate without proper Workers’ Comp.
The Fix: Work with an Illinois-licensed insurance broker who specializes in construction. They will know the exact wording and coverage amounts required by the City of Chicago Department of Buildings and ensure your Workers’ Comp is compliant with the Illinois Workers’ Compensation Commission.

Improperly Documenting Experience:

The Mistake: Submitting vague resumes, incomplete project lists, or unverified claims of experience. Chicago requires specific, verifiable documentation and often notarized affidavits.
The Fix: Start compiling detailed project lists early. Include dates, project types, your exact role, and values. Secure commitments for affidavits from licensed professionals who can attest to your work well in advance. Be prepared to back up every claim.

Ignoring Local Municipal Requirements Outside of Chicago:

The Mistake: Thinking that once you have a Chicago license, you’re good to go anywhere in Illinois. Or, conversely, not realizing that even small towns have some registration or permitting requirements.
The Fix: Always, always, always check with the specific city or county building department where your project is located, even for seemingly minor jobs. A quick call can save you headaches and fines.

Not Understanding Prevailing Wage for Public Projects:

The Mistake: Bidding on or accepting public works projects (state, county, municipal) without fully understanding and complying with Illinois’s prevailing wage requirements.
The Fix: If you plan to do any public work, familiarize yourself with the Illinois Department of Labor’s prevailing wage schedules and compliance procedures. This is a complex area with strict enforcement. Incorporate prevailing wage costs into your bids accurately.

Improper Business Entity Setup with the Illinois SOS:

The Mistake: Operating as a sole proprietorship without liability protection, or incorrectly filing articles with the Illinois Secretary of State, leading to delays or legal vulnerabilities.
The Fix: Consult with an Illinois business attorney and CPA to choose the correct business structure (LLC or Corporation) and ensure all filings with the Illinois SOS and IDOR are done correctly and promptly.

Lack of Patience and Follow-Up:

The Mistake: Expecting immediate results or failing to follow up regularly with the City of Chicago Department of Buildings on your application status.
The Fix: The process takes time. Be patient but persistent. Keep meticulous records of all communications, submission dates, and reference numbers. Follow up politely but regularly to ensure your application is moving forward.

By being aware of these common pitfalls and proactively addressing them, you’ll significantly increase your chances of a smoother and more successful journey to becoming a licensed general contractor in Illinois.

Renewal and Continuing Education Requirements: Keeping Your Illinois License Active

Getting your General Contractor license in Illinois (specifically, your Chicago GC license) is only half the battle. To maintain your ability to operate legally, you must understand and comply with renewal procedures and any continuing education (CE) requirements.

City of Chicago General Contractor License Renewal

Renewal Frequency: Chicago GC licenses typically have a renewal cycle, often every one or two years. The exact period will be specified on your license and by the Department of Buildings.
Renewal Process:
Online Portal: Renewals are usually processed through the City of Chicago’s online licensing portal.
Fees: Be prepared to pay a renewal fee, which can be substantial and similar in amount to the initial issuance fee, depending on your license class.
Updated Information: You’ll need to confirm or update your business information, contact details, and potentially provide updated insurance certificates and bond information. Ensure your insurance policies are continuously active and meet current requirements.
Good Standing: Your business must be in good standing with the Illinois Secretary of State (i.e., you’ve filed your annual reports and paid associated fees). If your SOS registration is lapsed, you won’t be able to renew your Chicago license.
Timeliness: Do not let your license lapse. Renew well in advance of the expiration date. Lapsed licenses can incur late fees, require re-application, or even force you to cease operations until reinstated.

Continuing Education (CE) Requirements

For General Contractors in Illinois, CE requirements are generally less extensive than for some specific trades licensed by the IDFPR (e.g., plumbers, electricians, roofers, who often have mandatory CE hours).

City of Chicago: Currently, the City of Chicago’s General Contractor licenses (Class A, B, C, D) do not typically have a specific, mandatory number of continuing education hours that must be reported to the DOB for renewal.
However, this does not mean you should stop learning. While not formally required for renewal, staying current with the latest revisions to the Chicago Building Code, construction safety standards (OSHA), new materials, and best practices is essential for your business’s success and compliance. The DOB can and does update its codes and regulations, and it’s your responsibility to know them.
Trade-Specific Licenses: If you or your employees hold separate trade licenses (e.g., an IDFPR-issued roofing license, plumbing license, or electrical license), those will have mandatory continuing education requirements. Ensure those individuals fulfill their specific CE obligations to keep their trade licenses active.

Importance of Ongoing Compliance:

Beyond formal renewals and CE, staying compliant in Illinois means:

Monitoring Code Changes: The Chicago Building Code, like all codes, is updated periodically. Subscribe to alerts from the City of Chicago Department of Buildings or relevant trade associations to stay informed.
Prevailing Wage Updates: If you perform public work, the Illinois Department of Labor updates prevailing wage rates twice a year (June and December). You must use the correct rates for the time work is performed.
Insurance & Bonds: Continuously ensure your insurance policies and bonds remain active and meet all current requirements.
Business Registration: Keep your business entity in good standing with the Illinois Secretary of State by filing annual reports and paying fees on time.

Treat your license as a valuable asset that requires continuous attention. Proactive management of renewals and an ongoing commitment to professional development will ensure your general contracting business thrives legally and successfully in Illinois.

SBA Resources for Illinois Contractors: Fueling Your Growth

The U.S. Small Business Administration (SBA) offers a wealth of resources designed to help small businesses, including general contractors, start, grow, and succeed. For contractors in Illinois, connecting with these resources can provide critical support, guidance, and access to capital.

Illinois District Office of the SBA:

The SBA has a dedicated District Office for Illinois, typically located in Chicago. This office serves as the primary point of contact for SBA programs and services throughout the state.
Website: Check the SBA’s official website (sba.gov) and navigate to the “Illinois District Office” page for local events, news, and direct contact information.
Services: They offer business counseling, training workshops, and information on government contracting and access to capital.

SCORE Illinois Chapters:

SCORE is a non-profit organization, a resource partner of the SBA, that provides free business mentoring and workshops. Many retired executives and entrepreneurs volunteer their time to mentor small business owners.
Locations: Illinois has numerous SCORE chapters, particularly in the Chicagoland area (e.g., Chicago, DuPage, Lake County) and other major cities like Peoria and Springfield.
How it Helps: A SCORE mentor can provide invaluable advice on business planning, financial management, marketing, and navigating government regulations – all crucial for a new or growing contractor.

Small Business Development Centers (SBDCs) in Illinois:

SBDCs are funded by the SBA and state governments, often hosted by universities or community colleges. They offer free, confidential business consulting and training.
Network: Illinois has a robust network of SBDCs across the state, including locations at the Illinois Department of Commerce and Economic Opportunity (DCEO), universities like Bradley, SIU, and UIC, and various community colleges.
Specialized Assistance: SBDCs can help contractors with business plan development, financial projections, market research, accessing loans, and understanding specific state and local regulations. Some even have specialists in government contracting.

Government Contracting Assistance:

Certifications: The SBA helps small businesses qualify for federal government contracting preferences through programs like 8(a) Business Development, HUBZone, Women-Owned Small Business (WOSB), and Service-Disabled Veteran-Owned Small Business (SDVOSB). These can be a significant advantage for GCs looking for public sector work in Illinois.
Procurement Technical Assistance Centers (PTACs) in Illinois: PTACs (now often rebranded as APEX Accelerators) are another SBA resource that provides specialized assistance to businesses seeking government contracts (federal, state, and local). They can help you register as a government contractor, understand bidding processes, and navigate compliance. Illinois has several PTACs/APEX Accelerators located throughout the state.
Illinois State Set-Asides: Beyond federal contracts, the State of Illinois also has programs to encourage contracting with small businesses, minority-owned businesses, and women-owned businesses. The Illinois Department of Central Management Services (CMS) oversees many of these initiatives.

Access to Capital (SBA Loan Programs):

The SBA doesn’t directly lend money but guarantees loans made by approved lenders (banks, credit unions). This reduces risk for lenders, making it easier for small businesses to get financing.
7(a) Loan Program: The most common type of SBA loan, offering flexible financing for various business needs, including working capital, equipment purchases, and real estate.
504 Loan Program: Provides long-term, fixed-rate financing for major fixed assets, such as real estate and equipment.
Microloans: Smaller loans (up to $50,000) for startups and small businesses, often available through non-profit community lenders.
How it Helps GCs: SBA loans can provide crucial capital for purchasing heavy equipment, funding initial project costs, expanding your crew, or acquiring commercial property in Illinois.

Connecting with these SBA resources is a smart strategic move for any Illinois contractor. They offer a foundation of knowledge, mentorship, and financial access that can significantly impact your business’s trajectory. Don’t leave free or low-cost help on the table.

The Illinois Construction Market Opportunity in 2026: Why It’s Worth It

You’ve gone through the hoops, navigated the Chicago DOB, secured your bonds, and dotted every “i” with the Illinois SOS. Why bother with all this effort? Because the Illinois construction market, particularly the Chicagoland area, offers significant and diverse opportunities for general contractors in 2026 and beyond. This isn’t just about surviving; it’s about thriving.

Chicago’s Enduring Strength:

Commercial Development: Chicago remains a major global city and a hub for corporate headquarters, finance, and technology. This drives ongoing demand for new office towers, corporate campus expansions, and commercial interior build-outs. Even with shifts to hybrid work, there’s a strong emphasis on modernizing and optimizing existing commercial spaces.
Residential Boom: While residential construction ebbs and flows, Chicago and its immediate suburbs continue to see robust demand for multi-family residential developments (apartments and condos), townhomes, and the renovation of its vast stock of historic housing. The desire for urban living and renewed investment in neighborhood infrastructure fuels this.
Mixed-Use Projects: The trend of mixed-use developments, combining residential, retail, office, and green spaces, is strong in Chicago, offering diverse project opportunities for GCs capable of managing complex, multi-faceted builds.
Institutional Growth: World-class universities, medical centers, and cultural institutions in Chicago consistently invest in new facilities, expansions, and renovations, providing a steady stream of large-scale, complex projects.

Infrastructure Spending – Rebuild Illinois and Federal Funds:

Rebuild Illinois: The state’s multi-year capital plan, “Rebuild Illinois,” continues to pump billions of dollars into infrastructure projects across the state. This includes roads, bridges, transit, waterways, public buildings, and broadband expansion. This is a massive opportunity for GCs, especially those willing to bid on public works.
Federal Infrastructure Investment: The federal Infrastructure Investment and Jobs Act (IIJA) is channeling significant funds to Illinois for transportation, water systems, broadband, and energy infrastructure. This creates a pipeline of projects for years to come.
Prevailing Wage Implications: These public works projects invariably come with prevailing wage requirements, as determined by the Illinois Department of Labor. While adding complexity, this also means stable, well-funded projects for compliant contractors.

Suburban Growth and Redevelopment:

Beyond Chicago, its sprawling suburbs are dynamic markets. Many established suburbs are undergoing revitalization, with downtown redevelopment projects, new commercial centers, and residential infill. Growing communities further out are expanding, requiring new schools, municipal buildings, and residential subdivisions.
Industrial/Logistics Sector: Illinois’s central location and robust transportation network make it a prime hub for logistics and distribution. This drives consistent demand for large-scale warehouse, fulfillment center, and industrial facility construction, particularly along major interstate corridors.

Sustainability and Modernization:

There’s a growing emphasis on sustainable building practices, energy efficiency retrofits, and smart building technologies across Illinois. GCs with expertise in green building certifications (LEED, Passive House), renewable energy integration, and building automation will find increasing demand.
Aging Infrastructure: Beyond new builds, a significant amount of work involves updating and modernizing Illinois’s aging infrastructure and building stock, from commercial retrofits to residential renovations.

Skilled Labor and Resources:

Illinois, particularly the Chicagoland area, has a deep pool of skilled labor through its strong trade unions and educational institutions. Access to experienced subcontractors, suppliers, and professional services is generally excellent.

The Illinois construction market in 2026 is not for the faint of heart; it’s competitive and demands compliance with rigorous local regulations. However, for the general contractor who is well-prepared, properly licensed, adequately insured, and committed to quality, the opportunities are vast and rewarding. By understanding the unique Illinois landscape and positioning your business strategically, you can build a legacy here.

How to Get Your General Contractor “License” in Illinois (Focusing on Chicago)

Since Illinois does not issue a statewide General Contractor license, your journey focuses on securing local municipal approvals, with the City of Chicago being the most comprehensive benchmark. Here’s your step-by-step roadmap:

Understand the Illinois Licensing Landscape: No State GC License. Internalize this fundamental truth: the State of Illinois does not issue a General Contractor license. Your licensing efforts will be directed at the specific cities and counties where you intend to work, with Chicago being the primary focus for most serious GCs.

Identify Your Target Municipality: Chicago is Key. Determine your primary area of operation. If you plan to work in the City of Chicago, prepare for its rigorous licensing process. If you operate exclusively in other municipalities, research their specific, often simpler, requirements.

Choose Your Chicago General Contractor License Class. For Chicago, select the appropriate license class (Class A, B, C, or D) based on the height and area of buildings you intend to work on. This decision dictates your experience, insurance, and bond requirements.

Establish Your Business Entity with the Illinois Secretary of State. Form a legal business entity (e.g., LLC or Corporation) by filing Articles of Organization/Incorporation with the Illinois Secretary of State (SOS) in Springfield. Obtain an Employer Identification Number (EIN) from the IRS and ensure you have an Illinois Registered Agent.

Secure Required Illinois-Specific Insurance and Bonds. Obtain mandatory Workers’ Compensation insurance for all employees through the Illinois Workers’ Compensation Commission. Secure Commercial General Liability (CGL) insurance meeting Chicago’s minimums (e.g., $1M/$2M) and naming the City of Chicago as an additional insured. Acquire a surety bond as required by your chosen Chicago license class.

Document Your Experience and Education. Compile a detailed record of your construction experience, including project lists, your roles, and verifiable references. Obtain notarized affidavits from licensed professionals attesting to your experience, as required by the City of Chicago Department of Buildings.

Prepare for and Pass the Chicago Contractor Exam (If Applicable). If applying for a Chicago Class A, B, or C license, prepare for and pass the required competency exam, which covers the Chicago Building Code, construction safety, and management principles. Utilize code books, ICC resources, and reputable exam prep materials.

Compile Your Application and Submit to the City of Chicago Department of Buildings. Meticulously complete the online application for your chosen Chicago GC license class. Upload all required supporting documents and pay the non-refundable application fee. Be prepared for a multi-week review process and potential requests for additional information.

Address Other Local Licenses as Needed. For projects outside Chicago, always contact the local city or county building department to understand and fulfill their specific contractor registration or licensing requirements, which typically involve proof of business registration and insurance.

Stay Compliant: Renewals, CE, and Prevailing Wage. Once licensed, diligently track and complete all renewal requirements for your Chicago license (and any other local registrations). While Chicago GC licenses don’t typically have formal CE, stay updated on code changes and ensure compliance with Illinois’s prevailing wage laws for public works projects. Keep your business entity in good standing with the Illinois SOS.

Frequently Asked Questions About General Contractor Licensing in Illinois

Here are some of the most common questions general contractors have when looking to get licensed in Illinois:

Do I need a statewide General Contractor license in Illinois?

No, Illinois does not issue a statewide General Contractor license. Licensing is handled at the local municipal level. The City of Chicago, for instance, has its own comprehensive licensing requirements, while other cities and counties will have their own specific regulations.

What is the Illinois Department of Financial and Professional Regulation (IDFPR) role in contractor licensing?

The IDFPR licenses specific trades statewide, such as roofing contractors, plumbers, and electricians. However, they do not license general contractors. For GC work, you’ll primarily interact with local city or county departments, most notably the City of Chicago Department of Buildings.

How long does it take to get a General Contractor license in Chicago?

The timeline can vary significantly. Forming your business with the Illinois Secretary of State, securing insurance and bonds, gathering extensive experience documentation, passing the exam, and the City of Chicago’s processing times can collectively take anywhere from a few weeks to several months. Realistically, budget 3 to 6 months for the entire process, assuming no major setbacks.

Are there reciprocity agreements for Illinois General Contractor licenses?

Since Illinois does not have a statewide General Contractor license, there are no statewide reciprocity agreements for GCs. If you’re licensed in another state, you will likely need to fulfill Chicago’s (or any other Illinois municipality’s) full licensing requirements, as your out-of-state GC license holds no direct weight here.

What are the insurance requirements for General Contractors in Illinois?

All businesses with employees in Illinois must carry Workers’ Compensation insurance, regulated by the Illinois Workers’ Compensation Commission. For licensing in the City of Chicago, you’ll also need Commercial General Liability (CGL) insurance, often with minimums of $1 million per occurrence and $2 million aggregate, and potentially a surety bond depending on your license class. The City of Chicago must also be named as an additional insured on your CGL policy.

Do I need to pay prevailing wages on projects in Illinois?

Yes, if you’re working on public works projects (state, county, municipal, or school district projects) in Illinois, you are required to pay your workers the prevailing wage rate as determined by the Illinois Department of Labor. This is a critical compliance point for GCs pursuing public sector work, and failure to comply can lead to severe penalties.

What’s the difference between a Class A, B, C, and D General Contractor license in Chicago?

These are tiered licenses issued by the City of Chicago Department of Buildings, defining the maximum height and area of buildings you can work on. Class A allows for any building regardless of height or area, while Class D is restricted to smaller, typically one- or two-story buildings up to 15,000 square feet. Each class has different experience, exam, insurance, and bond requirements.
