Kankakee County sits at the southern edge of the Chicago metro at about 106,000 residents, along the Kankakee River and anchored by Kankakee, Bradley and Bourbonnais. Its Planning Department handles unincorporated permitting and zoning, while the cities and villages run their own departments.
This guide covers the county’s unincorporated-area role, the river and agricultural context, the statewide layers, and where city work goes instead.
This guide covers unincorporated Kankakee County. Kankakee, Bradley, Bourbonnais and the other municipalities each run their own permitting.
Kankakee County pairs the southern metro edge with the Kankakee River and productive farmland, so the first question is whether the parcel is unincorporated county or inside a municipality. The Planning Department is the authority for unincorporated areas, where floodplain and land-use review often sit ahead of the building permit. Confirm the parcel before design.
What requires a building permit in Kankakee County?
Permit required
- New commercial, multi-family and residential construction, additions and change of occupancy
- Structural alterations, load-bearing changes, foundations, decks and retaining walls
- Electrical work — services, panels, circuits, solar and EV charging — under the adopted electrical code
- Plumbing under the statewide Illinois Plumbing Code, tied to a licensed plumber
- Mechanical and HVAC change-outs, and work affecting the energy envelope
- Re-roofing above the exempt scope, pools, signs, and demolition
Often exempt
- Minor repairs and maintenance replacing materials in kind
- Small accessory structures below the local threshold, where zoning allows
- Painting, flooring, cabinetry and other finish work
- Like-for-like fixture or appliance swaps with no alteration to wiring or piping
Because the code edition and its amendments are set locally, the exempt list and thresholds differ from one jurisdiction to the next — a project waved through in one town needs a full permit set in the next. An exemption from a building permit is never an exemption from zoning, the statewide energy or plumbing codes, or an electrical or plumbing permit. Confirm scope with the Planning Department before work starts.

Three Illinois codes apply statewide: the Illinois Energy Conservation Code, which applies even where a town does not actively enforce it; the Illinois Plumbing Code, from the Department of Public Health, which also licenses plumbers (a local government may adopt a stricter plumbing code, and Chicago has its own plumbing and energy codes and licenses its own plumbers); and the Illinois Accessibility Code. In unincorporated Kankakee County, the Planning Department administers the county’s adopted building code alongside zoning, floodplain and land-use review along the Kankakee River; the statewide Illinois codes apply on top.
Illinois leaves building codes to local government, but since 1 January 2025 any local code must regulate structural design at least as strictly as baseline editions of the International Building, Existing Building and Residential Codes, and where no code was adopted the statute sets minimums for commercial buildings and new homes (Public Act 103-0510). Illinois codes and the statewide baseline

The Planning Department is the authority for unincorporated Kankakee County, combining building permitting with zoning, floodplain and land-use review. The Kankakee River brings floodplain considerations, and productive farmland surrounds the metro core, where land use sits ahead of the building permit. The cities and villages run their own departments, so confirm the jurisdiction from the parcel first.
The county administers its adopted building code; the statewide Illinois energy, plumbing and accessibility codes apply on top, with plumbing tied to a state-licensed plumber.

Permit types
Residential permits
Unincorporated residential work spans river-adjacent properties, rural subdivisions and farmland parcels. Re-roofs, decks, solar and EV chargers need permits, plumbing is tied to a state-licensed plumber, and contractors register locally before pulling a permit.
Commercial permits
Commercial, industrial and agricultural work in unincorporated areas is a county matter, applying the adopted code with the statewide energy and accessibility requirements. All of it requires locally registered contractors and state-licensed plumbing.
Registration, trade licences and design professionals
Practically, three credential layers appear on Illinois projects: local contractor registration with the Planning Department; state licences for plumbing and roofing; and, on commercial and larger residential work, drawings from an Illinois-licensed design professional. Confirm what the Planning Department requires for the specific building before filing.
Illinois licenses plumbers through the Department of Public Health and roofing contractors through the Department of Financial and Professional Regulation; there is no state general contractor or electrician licence, and many jurisdictions require local registration.

Rather talk it over?
Call 1-855-478-4290 →Illinois sets one useful certainty in law: once a permit is issued, the code requirements in effect on January 1 of the year you applied govern for the life of that permit, so a mid-project code change will not move the target. Fee schedules, though, are local and change, so a figure from a neighbouring town is not reliable — ask the Planning Department for the schedule in force on your filing date.

Review, corrections and what actually causes delay
In Illinois, the first cause of delay is uncertainty over jurisdiction and the applicable code edition — filing under the wrong amendments, or with the county when a municipality should have it. After that come missing local contractor registrations, a plumbing scope not tied to a state-licensed plumber, energy-code documentation, and a submittal that did not match what the Planning Department requires. Build the review time into the schedule and confirm the checklist before filing.

Inspections in Kankakee County
Where a permit is required, standard checkpoints include footing and foundation, framing, rough-in electrical, plumbing and mechanical, insulation and energy, fire systems on commercial work, and final, with a certificate of occupancy before use. River-adjacent and farmland parcels add floodplain, land-use and septic verification.
Illinois is tightening inspector qualifications: from January 1, 2027, those who perform building inspections must hold International Code Council certification, with a grace period after hire. Confirm the notice the Planning Department needs and schedule around its inspection windows.
Do not cover work before the required inspection has been approved. Keep the issued permit, the approved plans, product listings, energy documentation and your correction responses available on site.

Permit records in Illinois sit with the local authority that issued them. Where the Kankakee County Planning Department is the authority for unincorporated Kankakee County, it holds the building permit, the inspection history and the certificate of occupancy. If you are buying, refinancing or renovating, confirm that past work was permitted rather than assuming it was — and confirm the code edition that was in force.
Confirm the authority having jurisdiction and the code edition first. Illinois’s local-adoption structure — with the statewide baseline now under it — means the applicable code and amendments vary by parcel. Confirm current requirements, fees and review turnaround for your filing date.

Frequently asked questions
Where do I get a Kankakee County building permit?

Is plumbing handled locally?
Partly. The Illinois Plumbing Code and plumber licensing are statewide (Department of Public Health), but a local government may adopt a stricter plumbing code, and plumbing permits and inspections are handled by the local building department where it runs them.

Permit-pulling trades typically register locally with the county; plumbing and roofing are state-licensed.
How do I run a Kankakee County permit search?
