Building permits in Springfield — Illinois's state capital, the seat of Sangamon County — are issued by Office of Public Works — Building & Zoning. Springfield enforces the ICC-based codes (as locally adopted).
This guide covers what requires a permit, the Springfield Permit Portal, fees, trade permits, and inspections — so your Springfield project stays on track.
Springfield — Illinois’s state capital and the seat of Sangamon County — issues building permits through the Office of Public Works — Building & Zoning. The city follows ICC-based codes as locally adopted. Springfield requires local contractor registration and separate permit applications for each trade (building, electrical, plumbing, mechanical). The $75 reinspection fee applies to failed inspections.
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 Springfield?
Under locally adopted codes, a permit is required for most construction activities:
Permit required

- Structural and load-bearing alterations
- Reroofing, siding, windows, sign installation
- Electrical, plumbing, and HVAC installations
- Decks, fences, pools, garages, sheds

Typically exempt
- Painting, wallpapering, tiling, carpeting, cabinet installation
- Cosmetic updates without electrical/plumbing relocation
- Freestanding decks ≤ 30 in. above grade
- Small at-grade patio slabs under 120 sq ft
Exemptions are narrow and scope-specific. When unsure, confirm with the building department before starting — see the penalty note below.
Get the permit issued before starting work. Building without a permit in Springfield can result in fines, stop-work orders, and double permit fees.

Springfield 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.
