This guide covers what requires a permit, the Joliet Permit Portal, fees, trade permits, and inspections — so your Joliet project stays on track.
Joliet — the fourth-largest city in Illinois and the seat of Will County — issues building permits through its Building Division within the Community Development Department. The city follows the 2018 I-Codes as locally adopted and is transitioning toward updated code compliance per the statewide mandate. Joliet requires local contractor registration and proof of insurance.
Illinois enacted its first-ever statewide building code on January 1, 2025 via Public Act 103-0510. All municipalities and counties must now enforce codes at least as stringent as the ICC model codes (IBC, IRC, IEBC). The Illinois Capital Development Board (CDB) oversees baseline compliance. However, each jurisdiction still administers its own permitting — processes, fees, and review timelines vary widely by city and county.

Joliet trade permits
Electrical, plumbing, and mechanical work each needs its own permit and appropriately licensed tradespeople.
Electrical permits
Required for service installations, panel upgrades, solar PV, EV chargers, and most wiring alterations — performed by an electrician licensed at the local level (Illinois does not issue a statewide electrician license).
Plumbing permits
Required for new plumbing, repipes, water heater changeouts, fixtures, backflow, and sewer connections — performed by a contractor licensed through the Illinois Department of Public Health (IDPH).
Mechanical (HVAC) permits
Required for HVAC installations, changeouts, ductwork changes, and venting modifications — performed by a qualified mechanical contractor per local requirements.
Miscellaneous & specialty
Fencing, pools, decks, sheds, and patio covers may require special permits depending on size and utility hookups. Demolition, sign, and right-of-way permits follow separate tracks.
Verify contractor licensing. Illinois does not issue a statewide general contractor license — general contractor licensing is handled at the local city or county level. However, two trades are state-regulated: plumbers are licensed by the Illinois Department of Public Health (IDPH), and roofing contractors are licensed by the Illinois Department of Financial & Professional Regulation (IDFPR) under the Roofing Industry Licensing Act. Electricians and HVAC technicians are regulated locally. Workers’ compensation insurance is mandatory for any Illinois employer — construction is classified as extra-hazardous.
