Illinois General Contractor License Requirements (2026)

Illinois does not issue a statewide general contractor license. Contractor licensing, registration, permits, insurance, and project qualifications are instead set by the authority having jurisdiction. Chicago is a substantial local example: its Department of Buildings licenses general contractors in five annual classes. A Chicago license is not an Illinois statewide credential and should not be assumed to satisfy another municipality’s requirements. Separate state credentials can also apply to particular scopes, such as plumbing, roofing, fire-sprinkler contracting, or security/alarm work.

Who Regulates This Work

State and Local Eligibility Rules

There is no single statewide application for this work, so this guide does not impose a uniform applicant-age, identification, or tax-number rule. Check the business, specialty-trade, and local authorities that govern the actual project. Illinois has no state general-contractor credential or statewide residency rule. Chicago’s program applies to work in Chicago regardless of the applicant’s domicile or residence; local requirements elsewhere vary.

State-level applicant screening

There is no statewide general-contractor character standard. Chicago’s application requires disclosures concerning bribery convictions, charges, and indictments for the applicant and controlling persons; its code sets the resulting eligibility limits.

Background-check requirements

There is no statewide general-contractor background-check program. Chicago requires government identification and specified criminal disclosures; other jurisdictions set their own process.

Experience and Scope Requirements

No single statewide year-based experience threshold governs the local or scope-specific path described here. The controlling requirement is Illinois sets no statewide general-contractor experience requirement. Chicago’s cited application rule does not prescribe a fixed number of experience years, but does require business history, a financial-solvency affidavit, insurance, and other application information..

Relevant records and local documents

• No Illinois state general-contractor experience documentation is required
• Chicago requires the location from which the applicant has engaged in general contracting during the preceding five years
• Other local authorities may require their own experience, reference, business, or insurance documentation

Education and scope boundaries

Not applicable at the state general-contractor level. Follow the requirements of the local licensing authority.

Testing Requirements

There is no single statewide trade examination for the local or scope-specific path described here. The applicable testing rule is: Illinois has no state general-contractor examination. Chicago’s cited general-contractor licensing provisions do not prescribe a written trade examination.

Examination fee: No Illinois state general-contractor examination fee.

Retake policy: Not applicable at the state level.

Insurance, Bonds, and Project Requirements

No statewide contractor-license bond applies to the local or scope-specific path described here. A city, county, permit authority, public owner, or project contract may still require a bond, so confirm the actual project requirements before bidding.

General liability

Illinois does not impose a statewide general-contractor liability minimum. Chicago requires commercial general liability and names the City as additional insured: Class A $5,000,000 per occurrence; Class B $3,000,000 per occurrence; Classes C and D $1,000,000 per occurrence/$2,000,000 aggregate; Class E $1,000,000 per occurrence. These are Chicago rules, not statewide requirements.

Workers' compensation

Workers’ compensation is an employer obligation under Illinois law, not a condition of a statewide general-contractor license. Confirm the applicable employment, contract, and local requirements for the project.

Financial or filing requirements

No statewide general-contractor bond or financial-statement rule is identified. Chicago requires a financial-solvency affidavit as part of its application; local jurisdictions can impose different requirements.

Renewal and Ongoing Compliance

The Illinois General Contractor — No State License (Local Requirements Apply) runs on a year renewal cycle. The current renewal fee is $300. There is no statewide license to renew. Chicago licenses expire one year after issuance; expired licenses may only be reinstated within three years.

Continuing education: Illinois has no statewide general-contractor continuing-education requirement. Confirm any local program requirement directly.

Out-of-State Credentials and Local Recognition

Illinois has no single statewide credential for this path to transfer through NASCLA. An authority may consider an outside license, examination, or experience record only under its own current rules.

There is no Illinois state general-contractor credential to reciprocate. A local authority may decide whether it recognizes any outside credential or documentation; never assume that it does.

Step-by-Step Compliance Roadmap

1. Identify the project jurisdiction and scope. Determine the city, county, or other authority that will issue the permit and identify all separately regulated work in the project.
2. Check the local contractor program before bidding. Confirm current registration or license requirements, class limits, permits, insurance, fees, and renewal terms with the authority having jurisdiction.
3. Use the correct Chicago class when working in Chicago. Chicago Class A is unlimited; B is limited to $20 million at a single site; C to $10 million; D to $4 million; and E to $500,000. Demolition and excavation authority also differs by class.
4. Prepare the local application materials. For Chicago, this includes entity/controlling-person information, the class selected, fee, financial-solvency affidavit, Illinois authorization to do business when applicable, insurance, identification, and the required bribery disclosures.
5. Meet project-specific insurance and specialty requirements. Use the actual local program and project contract. A general-contractor license does not replace an applicable state or local specialty credential.
6. Obtain permits and maintain local eligibility. Permit issuance, inspections, reporting changes, and renewals are controlled locally. Chicago requires changes in application information to be reported within 14 business days.

Common Compliance Mistakes

The issues below are the most likely to create an unlicensed-work, registration, permit, or scope problem for Illinois General Contractor work, based on the official sources cited on this page.

Treating Chicago’s program as statewide

Chicago is a local program. Verify each project jurisdiction’s own contractor and permit rules.

Using the wrong Chicago class

Using outdated biennial fee information

Chicago’s current general-contractor licenses are annual, with Class E at $300 and Class A at $3,500.

Assuming the GC credential covers specialty work

The appropriate state or local specialty rules still apply to the actual work performed.
