Building permits in Naperville — One of Illinois's largest cities, spanning DuPage and Will counties — are issued by TED Business Group — Building Services. Naperville enforces the 2024 ICC Building Codes (adopted April 2026).
This guide covers what requires a permit, the Civic Access Portal, fees, trade permits, and inspections — so your Naperville project stays on track.
Naperville — one of Illinois’s most affluent suburbs spanning DuPage and Will counties — issues permits through the TED Business Group — Building Services. As of April 1, 2026, the City Council adopted the 2024 ICC building codes for all new permit applications. All applications must be submitted electronically through the Civic Access Portal and conform to the City’s electronic submittal requirements.
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.
What requires a building permit in Naperville?
Under locally adopted codes, a permit is required for most construction activities:

Get the permit issued before starting work. Building without a permit in Naperville can result in fines, stop-work orders, and double fees. Work started without a permit may require opening walls for inspection.

Naperville 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.
