Champaign County sits in east-central Illinois at about 210,000 residents, anchored by the University of Illinois at Urbana-Champaign and surrounded by some of the most productive farmland in the state. The county issues no building permits: unincorporated construction needs a zoning use permit from the Champaign County Department of Planning and Zoning, at Scott M. Bennett Administrative Center, 102 E. Main Street, Urbana (217-384-3708, Monday to Friday 8:00am to 4:30pm). Champaign, Urbana and the smaller cities run their own building departments.
This guide covers the county’s unincorporated-area role, the university and farmland context, the statewide layers, and where city work goes instead.
This guide covers unincorporated Champaign County. Champaign, Urbana, Rantoul and the other municipalities each run their own permitting.
Champaign County pairs a major university with prime farmland, so the first question is whether the parcel is unincorporated county or inside a municipality. In unincorporated areas the county’s zoning use permit is the county permit, and land use and agricultural zoning often settle what can be built; Champaign and Urbana run their own building departments. Confirm the parcel before design.
What requires a building permit in Champaign 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 county 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 Champaign County, the county has not adopted a building code and does not inspect buildings under construction; its Department of Planning and Zoning reviews zoning, floodplain and stormwater rules. The statewide Illinois codes still apply.
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 county is the zoning authority for unincorporated Champaign County: a zoning use permit is required for construction and land use, except work covered by the agricultural exemption. Much of the unincorporated county is prime farmland, so agricultural zoning and land use frequently settle what can be built. Champaign and Urbana — and the university’s own construction — run separately, so confirm the jurisdiction from the parcel first.

Permit types
Residential permits
Unincorporated residential work spans farmland parcels and rural subdivisions. New homes, additions, accessory buildings, decks, pools and freestanding solar arrays need a county zoning use permit; there is no county building permit or trade permit, and plumbing is tied to a state-licensed plumber.
Commercial permits
Commercial and non-farm work in unincorporated areas needs a county zoning use permit; with no county building code, the statewide energy and accessibility requirements and state-licensed plumbing still apply, and agricultural buildings can fall under the agricultural exemption.
Registration, trade licences and design professionals
Practically, the credentials that matter in unincorporated Champaign County are state licences for plumbing and roofing and, on commercial and larger residential work, drawings from an Illinois-licensed design professional. The county has no contractor registration. Confirm what the department needs for the specific project 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.

Champaign County permit costs and fees
Budget the county zoning use permit, a $33 certificate of compliance, and any land-use, floodplain or stormwater review. The fees are by floor area, not valuation: $12 per 100 square feet for single- and two-family dwellings, and $275 plus $15 per 100 square feet for other buildings, with a $1,500 cap for any one structure (wind towers and solar farms excepted).

|---|---|
| Building permit | No county building permit; the zoning use permit is charged by floor area |
| Plan review | No county building plan review; a $33 certificate of compliance is added to most permits |
| Trade permits | None from the county |
| Contractor registration | None from the county |
| Zoning and impact | Local zoning review, and impact or capital fees in growth areas |
| Re-inspections and revisions | Additional fees for failed inspections, revisions and expired permits |
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 county for the schedule in force on your filing date.

Champaign, Urbana and Rantoul file with their own counters.
Farmland parcels raise these before the zoning use permit.
The county has no building code, so the statewide codes govern.
The county has no contractor registration.
Plumbing and roofing are state-licensed; the county issues no trade permits.

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 county requires. Build the review time into the schedule and confirm the checklist before filing.
A building permit carries a validity period set by Champaign County; confirm the expiry on phased or delayed work before it passes. Permit validity in Illinois
Inspections in Champaign County
The county does not inspect buildings under construction. Its Department of Planning and Zoning inspects for zoning compliance and issues a zoning compliance certificate; well and septic permits are separate public-health matters.
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 county 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. In unincorporated Champaign County, the Department of Planning and Zoning holds zoning use permits and zoning compliance certificates; there are no county building permits or building inspection records. 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 Champaign County building permit?
There is no county building permit. Unincorporated work needs a zoning use permit from the Champaign County Department of Planning and Zoning, Scott M. Bennett Administrative Center, 102 E. Main Street, Urbana (217-384-3708, Monday to Friday 8:00am to 4:30pm); Champaign, Urbana and the other municipalities run their own building departments.
Does farmland zoning affect what I can build?
Yes. Much of unincorporated Champaign County is prime farmland, and agricultural zoning frequently settles what can be built before a zoning use permit is issued.
Inspections are where schedules slip.
Get a free quote →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. In Champaign County, confirm with the department.
Who permits university construction?
University of Illinois construction is handled through the state and the university, separate from the county and city building departments.
Do contractors register with the county?
No. The county has no contractor registration and issues no trade permits; plumbing and roofing are state-licensed.
