Licensed Remodeling Contractor in Illinois: How to Verify Before You Hire

Illinois does not issue a statewide remodeling contractor license, but Chicago's strong local licensing requirements and other municipal systems create meaningful credentials that remodeling contractors must hold. Understanding what applies in your area is critical before hiring any remodeling contractor in Illinois.

What license does a remodeling contractor need in Illinois?

Illinois has no statewide general contractor or remodeling contractor license. However, Chicago requires contractors performing residential renovation work above $1,000 to hold a City of Chicago Home Repair License or a General Contractor License from the Chicago Department of Buildings. For work above $100,000, a full General Contractor license is required. These are meaningful credentials that cover the vast majority of residential remodeling work in the Chicago metropolitan area.

Outside Chicago, Illinois municipalities have varying local requirements. Some cities like Evanston, Naperville, and Aurora have their own contractor registration systems. Others rely on permit-based oversight without formal contractor registration. Homeowners outside Chicago should contact the local building department to understand what credentials are required in their specific jurisdiction.

Illinois specialty contractors — electricians, plumbers, and HVAC technicians — require state licenses from their respective boards. Any remodeling contractor must use appropriately licensed specialty subcontractors for these trade components, regardless of the local contractor licensing requirements that apply to the general contractor.

How do you look up a remodeling contractor's credentials in Illinois?

For Chicago projects, verify Home Repair License or General Contractor license status at the Chicago Department of Buildings license portal at chicago.gov/buildings. Search by contractor name, business name, or license number. The database shows license type, status, expiration date, and any violations or disciplinary actions on file.

For municipalities outside Chicago, contact the local building department directly or check the city's website for a contractor registration lookup. Illinois does not maintain a statewide contractor registration database for general contractors, so verification outside Chicago requires jurisdiction-specific research.

Illinois' Department of Professional Regulation does license specialty contractors. Verify electrical, plumbing, and HVAC credentials through the appropriate state licensing boards to confirm all specialty tradespeople involved in your remodel are properly licensed in Illinois.

What scope of work triggers licensing for Illinois remodeling?

In Chicago, home repair work above $1,000 requires either a Home Repair License or General Contractor License. Work above $100,000 requires a full General Contractor License. This covers virtually all kitchen renovations, bathroom remodels, additions, and whole-house renovations in Chicago.

Illinois' Home Repair and Remodeling Act applies statewide and requires written contracts for all home improvement work above $1,000. The Act also provides homeowners with a three-day right of cancellation for contracts signed at their home. These protections apply regardless of whether a specific municipality requires contractor registration.

Permit requirements for structural changes, additions, and systems work apply in most Illinois municipalities. Work requiring permits must be performed by contractors who are registered to pull permits in that jurisdiction. A remodeling contractor who advises against permits is advising illegal action and is likely avoiding the permit process because they lack required credentials.

What bond and insurance does an Illinois remodeling contractor need?

Chicago requires Home Repair License holders to carry $100,000 in general liability insurance and General Contractor license holders to carry $1,000,000. Workers' compensation is required for all Illinois employers with one or more employees. These requirements are verified as part of the Chicago licensing process.

Request a certificate of insurance before any work begins. Confirm the coverage amount matches the license type and is appropriate for your project size. Workers' compensation can be verified through the Illinois Workers' Compensation Commission. For projects in the $50,000-$200,000 range, ask for $1,000,000 in general liability regardless of the license type.

A surety bond is not required for Chicago Home Repair License holders, but many professional remodeling contractors carry one voluntarily. A bond provides additional financial protection if the contractor abandons the project or fails to pay subcontractors.

What are common remodeling scams to watch for in Illinois?

Chicago sees significant remodeling fraud, particularly in neighborhoods experiencing gentrification. Unlicensed contractors target homeowners in transitional neighborhoods, offer below-market quotes, take large deposits, and perform substandard work or disappear before completion. The Chicago Department of Buildings actively investigates unlicensed contractor complaints.

Permit fraud is a common issue in Chicago. Some contractors pull permits using other contractors' license numbers without authorization, or misrepresent the scope of work to obtain permits for work they are not authorized to perform. Verify permits directly with the Chicago DOB rather than accepting the contractor's assurance.

Storm damage contractor fraud follows major weather events in Illinois, particularly after hailstorms in the Chicago suburbs and tornado events in downstate Illinois. Out-of-state crews arrive, collect deposits, and disappear or produce work that does not withstand subsequent weather.

What should you check before signing a remodeling contract in Illinois?

For Chicago projects, verify an active Chicago DOB contractor license. For other Illinois municipalities, verify local registration requirements and confirm specialty contractor licenses for all tradespeople. Confirm insurance at levels appropriate for your project. Get a written contract as required by the Home Repair and Remodeling Act.

Illinois' Home Repair and Remodeling Act gives you three days to cancel a contract signed at your home. Do not sign under pressure. Verify the contractor's credentials before signing, not after.

Chicago's older housing stock — particularly homes in the city's bungalow belt and north side neighborhoods — often contains lead paint and outdated electrical systems. Ask your remodeling contractor about hazardous material assessment and EPA RRP compliance for pre-1978 homes.
