What Can a Handyman Do in Cook in Cook County, Illinois?

Illinois does not have a single, statewide “general contractor” license for typical handyman/home-improvement work; licensing is mostly trade-specific (plumbing is state-licensed; electrical/HVAC are commonly licensed at the local level) and many contractor rules are set by the city/village where the work occurs. In Cook County (especially Chicago and many suburbs), you typically need a local business license and must pull permits for regulated work even if you call yourself a handyman; there is no simple statewide dollar-threshold “handyman exemption” that lets you bypass trade licensing/permits.

In IL, jobs under $None typically don't require a contractor license. Always verify with your local licensing authority.

✅ What You Can Do Without a License

Interior/exterior painting and staining (non-lead regulated practices still apply; follow EPA RRP rules for pre-1978 homes when applicable)
Minor drywall patching and plaster repair that does not alter structural framing
Basic carpentry: install trim, baseboards, crown molding, shelving, and cabinetry (non-structural)
Replace interior doors and hardware (knobs, hinges) without changing structural openings
Tile repair or backsplash installation (non-structural; follow waterproofing best practices)
Gutter cleaning and minor gutter repairs (not full roof replacement as a “roofing contractor” scope)
Assemble furniture, mount TVs/shelves to studs with proper anchors (subject to landlord/HOA rules)
Minor exterior repairs that do not change structure or require a permit (scope depends on municipality)

⚠️ What Requires a License

Plumbing work for the public (Illinois state plumbing licensure required; avoid drain line modifications, water heater hookups, new supply lines, etc. unless properly licensed and permitted)
Electrical work where the municipality requires a licensed electrical contractor/electrician to pull permits (commonly panel work, new circuits, service upgrades, significant rewiring)
HVAC/mechanical system installation/alteration where local mechanical licensing/permits are required; refrigerant handling requires EPA Section 608 certification
Roof replacement and many roof repair activities when offered as a roofing contractor (Illinois roofing licensure requirement through IDFPR)
Structural work (load-bearing walls, beam modifications, foundation work) requiring building permits/engineering in many municipalities
Any work requiring a building permit in your municipality when the permit must be pulled by a licensed/registered contractor

State Licensing Rules (IL)

Even when a state credential is not required for “general handyman” tasks, you still must comply with: local building permits, local contractor registrations/licensing (common in Chicago and suburbs), and specialty-trade licensing (especially plumbing). Many municipalities also restrict who can pull permits (often a registered/licensed contractor).

Business License — Cook

Required. Varies by municipality (Cook County contains many cities/villages; major requirements differ notably for Chicago vs. each suburb vs. unincorporated Cook County)

Permit vs. Contractor License — What's the Difference?

A license (or contractor registration) is your legal authorization to offer/perform a category of work; a permit is job-specific approval from the building department to perform regulated work at a specific address. Even if you don’t need a state license for general handyman services, you can still be required to obtain permits—and many jurisdictions only allow licensed/registered contractors to pull them.

Important Notes for Cook in Cook County, Illinois Handymen

Insurance: Many municipalities and clients require general liability insurance (commonly $1,000,000 per occurrence) and workers’ compensation if you have employees; even when not required, it’s a standard expectation for contractor registration and commercial jobs.
Chicago/Cook suburbs frequently require contractor registration and may require you to show insurance certificates and sometimes bonding to pull permits.
If you touch pre-1978 painted surfaces in homes/child-occupied facilities, EPA Renovation, Repair and Painting (RRP) rules may apply (federal requirement).
Do not rely on a “job under $X” rule to avoid licensing—Illinois is driven by trade scope and local permitting, not a single statewide handyman threshold.
