Licensing Requirements
Illinois does not issue a single statewide general contractor license. However, contractors must register with the Illinois Department of Financial and Professional Regulation (IDFPR) if performing roofing work. The City of Chicago requires a City of Chicago General Contractor License issued by the Department of Buildings (DOB). Requirements include: proof of $1 million general liability insurance, workers' compensation coverage, a passing score on the Chicago DOB contractor exam (covers building code, safety, and trade knowledge), and a $250 biennial license fee. The exam is administered by the Chicago DOB and covers the Chicago Building Code. Licenses must be renewed every two years. Specialty trades (electrical, plumbing, HVAC) require separate state or city licenses regardless of GC status. Contractors working in suburban Cook County or collar counties face municipality-specific registration requirements — no single county-wide license exists.
Permit Requirements
Any structural, electrical, plumbing, HVAC, or addition work in Chicago requires permits pulled through the Chicago Department of Buildings via the Chicago Permit Portal (E-Plan). Standard permits required for most GC work include: Building Permit (required for new construction, additions, alterations), Electrical Permit (pulled by licensed electrician), Plumbing Permit (pulled by licensed plumber), and Zoning approval for additions or changes of use. The City of Chicago uses an automated permit review system for simple projects (Standard Plan Review) and a full plan review process for complex work. Permit fees are calculated based on project valuation — typically 0.5% to 1% of total project cost. Work without permits subjects contractors to stop-work orders, fines up to $1,000 per day, and mandatory demolition of unpermitted work.
Inspection Schedule
Inspections are scheduled through the Chicago DOB online portal or by phone. Typical inspection sequence for a residential remodel: (1) Rough framing inspection after structural work is complete and before drywall, (2) Rough electrical inspection (coordinated with licensed electrician), (3) Rough plumbing inspection (coordinated with licensed plumber), (4) Insulation inspection where applicable, (5) Final inspection upon project completion. Inspectors are typically available within 3 to 10 business days of request — longer during peak season. Failed inspections require re-inspection scheduling, which adds 3 to 7 days minimum. Commercial projects follow a similar sequence but often require multiple interim inspections tied to the approved plan set.
Insurance Minimums
Chicago DOB requires minimum $1,000,000 per occurrence / $2,000,000 aggregate general liability insurance for a City of Chicago General Contractor License. Workers' compensation insurance is required under Illinois law for any contractor with one or more employees (820 ILCS 305). Subcontractors must carry their own coverage or be listed on the GC's policy. Most commercial clients and property managers in Chicago require additional insured endorsements and umbrella coverage of $5,000,000 or more. Bonding requirements vary by project — public works contracts require payment and performance bonds per the Illinois Public Construction Bond Act (30 ILCS 550).

How to Get Licensed
Verify Business Entity and Registration
Before applying for a City of Chicago General Contractor License, ensure your business is properly registered with the Illinois Secretary of State (for LLCs or corporations) or registered as a sole proprietor with Cook County. Obtain your Federal Employer Identification Number (FEIN) from the IRS. Your business entity must be in good standing — the DOB will verify this during the application process.
Obtain Required Insurance Coverage
Secure a general liability insurance policy with minimum limits of $1,000,000 per occurrence and $2,000,000 aggregate. If you have any employees, obtain a workers' compensation policy as required by Illinois law (820 ILCS 305). Your insurance certificates must name the City of Chicago as an additional insured. Work with a commercial insurance broker familiar with Chicago contractor requirements to ensure the policy language meets DOB standards.
Study and Pass the Chicago DOB Contractor Exam
The City of Chicago Department of Buildings administers a contractor examination that covers the Chicago Building Code, safety regulations, and general construction knowledge. Obtain the current exam study materials from the Chicago DOB website. Schedule your exam through the DOB Examination Division. A passing score is required before your license application can be approved. Exam fees and scheduling windows are posted on the Chicago DOB portal — confirm current details at chicago.gov/buildings.
Submit the License Application to Chicago DOB
Complete the General Contractor License application through the City of Chicago Department of Buildings. Required documentation includes: completed application form, proof of passing exam score, certificate of insurance (GL and workers' comp), business registration documents, and the biennial license fee of $250. Applications are submitted through the Chicago DOB licensing portal or in person at City Hall. Processing times typically run 2 to 4 weeks.
Register for Chicago Business License (if applicable)
In addition to the contractor license, businesses operating in Chicago may need a City of Chicago Business License issued by the Department of Business Affairs and Consumer Protection (BACP). This is separate from the DOB contractor license and applies to your business location. Visit chicago.gov/bacp to determine if your business activity requires this registration.
Verify Specialty Trade Subcontractor Licenses
As a general contractor, you are responsible for ensuring all specialty trade work on your projects is performed by properly licensed subcontractors. In Chicago, electricians must hold a City of Chicago Electrical Contractor License, plumbers must hold an Illinois Plumbing License, and HVAC contractors require city registration. Do not allow unlicensed trade work on your projects — violations result in stop-work orders and can jeopardize your own GC license.
Renew License Every Two Years
The City of Chicago General Contractor License must be renewed biennially. Renewal requires proof of current insurance coverage, payment of the renewal fee, and confirmation that your business entity remains in good standing with the state. The DOB sends renewal notices, but it is your responsibility to track your expiration date and renew on time. Operating with an expired license subjects you to fines and potential license revocation.
About This Market
Chicago's general contracting market is one of the largest and most competitive in the Midwest. With approximately 1,317 licensed contractor establishments in Illinois per Census data, and a significant concentration in the Chicago metro, you're working in a saturated field where reputation and relationships drive the pipeline more than advertising. Demand is strong — the city has an aging housing stock, a steady commercial development cycle, and a robust multifamily renovation market driven by property investors and condo associations. Project types range from vintage two-flat gut rehabs in neighborhoods like Logan Square and Pilsen to high-end single-family remodels on the North Shore to commercial tenant buildouts in the Loop and River North. Labor costs in Chicago are among the highest in the Midwest — union labor dominates commercial work, and prevailing wage requirements apply to any public-funded project. Material costs track national trends but carry a Chicago premium on delivery and logistics. Margins are tighter than they look on paper once you account for permit fees, inspection delays, and subcontractor markups.
If you want to work this market, you need your City of Chicago General Contractor License — no shortcuts. Get familiar with the Chicago Building Code, because the DOB exam tests it directly and inspectors enforce it without apology. Plan your permit pulls early; the E-Plan system has improved but complex projects still see 4 to 8 week review cycles. If you're doing any public work or school district contracts, the Illinois Prevailing Wage Act applies and wage audits are real — keep your certified payroll records clean. Stack your project starts in spring, because October through March will slow you down whether you like it or not, especially on exterior and addition work. Build relationships with your local DOB inspector district and your permit expediter — in Chicago, knowing the process is half the job. Don't subcontract electrical, plumbing, or HVAC without verified licensed subs; the city will shut you down and the liability lands on your license. Cash flow management is critical — Chicago projects run long due to inspection scheduling and weather, and GCs who don't buffer for 90-day payment cycles from commercial clients get squeezed hard.

Frequently Asked Questions
Do I need a state license to work as a general contractor in Illinois?
Illinois does not have a statewide general contractor license. However, if you're working in Chicago, you are required to hold a City of Chicago General Contractor License issued by the Chicago Department of Buildings. This requires passing the Chicago DOB contractor exam, proof of general liability insurance ($1M per occurrence), and workers' compensation coverage. Suburban municipalities have their own registration requirements — there is no uniform county-level license. Always verify with the specific municipality before pulling permits.

How much does a general contractor charge for a kitchen remodel in Chicago?
In the Chicago market, a mid-range kitchen remodel typically runs $25,000 to $75,000 depending on scope, finishes, and whether structural work is involved. High-end remodels with custom cabinetry, premium appliances, and layout changes can exceed $100,000. Labor costs in Chicago are elevated compared to national averages due to union labor availability and prevailing wage norms on larger projects. These are market estimates based on contractor pricing data for the Chicago metro area. Always get three competitive bids and verify the scope is itemized — Chicago GCs vary significantly in how they structure allowances.
How many general contractors are licensed in Illinois?
According to U.S. Census Bureau data, there are approximately 1,317 licensed general contracting establishments in Illinois. The Chicago metro area accounts for a substantial share of that total, making it one of the most competitive GC markets in the Midwest. This figure covers registered business establishments and does not capture sole proprietors or unlicensed operators working informally.

What permits are required for a home addition in Chicago?
A home addition in Chicago requires a Building Permit through the Chicago Department of Buildings, obtained via the E-Plan online portal. Depending on scope, you will also need separate Electrical and Plumbing permits pulled by licensed trade contractors. Additions triggering zoning changes — such as exceeding lot coverage limits or altering building height — require Zoning Board of Appeals approval before permit issuance. Plan review for additions typically takes 4 to 8 weeks for complex projects. Permit fees are calculated based on project valuation, generally 0.5% to 1% of total cost. Working without permits risks stop-work orders and mandatory demolition. Source: City of Chicago Department of Buildings, Chicago Municipal Code Title 14A.
When is the best time to hire a general contractor in Chicago?
For interior projects, fall and winter (November through February) offer the best contractor availability and sometimes more competitive pricing as demand slows. For exterior work, additions, or projects requiring consistent site access, late summer through early fall is the practical window before Chicago weather becomes a factor. Spring (April through June) is the busiest booking period — contractors are scheduling out 6 to 12 weeks during peak season, and permit review times lengthen at the Chicago DOB as application volume spikes. If you're planning a major project, lock your contract and permit application in by February to get ahead of the spring rush. These timing patterns are based on Chicago-area contractor market observations and seasonal construction trends.
