Handyman License Requirements in Joliet, IL

By Ray Duke, Founder of Bulletproof Handyman · Last reviewed July 2026

In Joliet, Illinois (Will County), handymen and small contractors are NOT subject to a statewide dollar-threshold exemption—Illinois has no statewide general contractor license. However, Joliet REQUIRES a City business license, and certain trades (plumbing, roofing, electrical, HVAC) require state or local licenses regardless of project size. Any work requiring a building permit also requires a licensed contractor. General handyman work like painting, drywall repair, and carpentry can be performed without a state license, but you must obtain a Joliet city business license and comply with all local permit requirements.

⚠️ What Requires a Contractor License

The following work requires a state-issued contractor license in IL. Performing this work without a license exposes you to fines, stop-work orders, and civil liability:

• ANY electrical work beyond simple fixture changes – requires City of Joliet Electrical License
• ANY plumbing work – requires Illinois Department of Public Health State Plumbing License (even minor work like fixture replacement or drain clearing)
• HVAC system installation, repair, or maintenance – requires City of Joliet HVAC License and federal EPA 608 certification for refrigerant work
• Roofing work of any kind – requires Illinois Department of Financial and Professional Regulation State Roofing License
• Any work requiring a building permit (water heater installation, structural modifications, window/door replacement affecting structure, electrical panel work)
• Work in the Joliet Historic District affecting exterior appearance – requires Historic Preservation Permit
• Any work on federal property (Midewin National Tallgrass Prairie) – requires SAM.gov registration for contracts over $10,000

State Contractor Licensing Law (IL)

Even though no statewide handyman exemption exists, handymen may perform general repair and maintenance (painting, drywall patching, trim carpentry, basic carpentry) without a state license. However, ANY work requiring a building permit, and ALL plumbing, roofing, electrical, and HVAC work require appropriate licenses. Verify exemption limits directly with the City of Joliet Community Development – Inspection Division.

Permit vs. Contractor License — The Legal Difference

A LICENSE is a credential issued by a government agency (state or city) that authorizes you to perform a specific trade or operate a business. A PERMIT is a one-time approval for a specific project, issued before work begins. In Joliet, you need a BUSINESS LICENSE to operate as a contractor, and you need TRADE LICENSES (electrical, plumbing, HVAC, roofing) to perform those specific trades. PERMITS are required for individual projects that affect building structure, electrical systems, plumbing, HVAC, or historic properties. Even if you hold all required licenses, you MUST obtain permits for qualifying work before starting. Performing permitted work without a permit can result in fines, stop-work orders, and liability issues.

Business Entity Registration (IL)

To operate legally you must register your business. LLC filing fee in IL: $150 (one-time).

Compliance Notes for Joliet, Illinois (Will County)

• Insurance: General liability insurance is STRONGLY RECOMMENDED for all handymen and contractors in Illinois. For roofing work, it is REQUIRED ($250,000 minimum for Limited License, $500,000 for Unlimited). For HVAC work, EPA 608 certification is REQUIRED for any refrigerant handling.
• Compliance Mistakes: (1) Performing plumbing or electrical work without state/local licenses – this is illegal and can result in fines and liability. (2) Failing to pull required permits – stop-work orders and fines can result. (3) Operating without a Joliet business license – the city can impose penalties and shut down operations. (4) Working in the historic district without Historic Preservation approval – fines up to $5,000+.
• Illinois-Specific Quirks: Illinois has NO statewide general contractor license, but plumbing and roofing ARE licensed at the state level. Electrical and HVAC are licensed locally only. This creates a patchwork where some trades are state-regulated and others are city-regulated. Always verify which authority governs the specific trade you're performing.
