Kenosha County's Department of Planning and Development runs zoning, sanitation and land conservation for the unincorporated townships of Brighton, Paris, Randall, Somers and Wheatland — and it front-loads the process: a zoning permit must be issued before the town building inspector will issue a building permit.
The department administers the Kenosha County General Zoning and Shoreland/Floodplain Zoning Ordinance, which is Chapter 12 of the county's municipal code, alongside the sanitary code and private sewage ordinance, the land division ordinance and the stormwater, erosion control and illicit discharge ordinance.
This guide covers unincorporated Kenosha County. The City of Kenosha, Pleasant Prairie, Twin Lakes, Salem Lakes, Paddock Lake and Bristol permit their own construction — the city enforces the 2021 code editions from its own dated page.
The survey comes back after the build. County zoning code requires the owner to hire a Wisconsin professional surveyor to update the plat of survey after any building is constructed — house, detached accessory building or addition — to verify it was built to the approved size and setbacks. The due date is printed on the face of the zoning permit and can be no later than permit expiration. Decks, balconies, pools and fences are exempt.
What requires a building permit in Kenosha County?
Wisconsin splits construction into two statewide instruments, and neither one is a city invention. One- and two-family homes run on the Wisconsin Uniform Dwelling Code (SPS 320 to 325), a code Wisconsin wrote for itself — the state never adopted the International Residential Code, so IRC chapter references from other states simply do not apply here. Everything that is a public building or a place of employment, including any residential building of three or more units, runs on the Wisconsin Commercial Building Code (SPS 361 to 366), which moved to the 2021 I-codes effective September 1, 2025; plans submitted on or after November 1, 2025 must comply with the 2021 editions. Under Wis. Stat. 101.65(1c) and 101.02(7r)(a), Kenosha County may not enforce different technical standards — local ordinances must strictly conform to the state codes.
Typically permit required
- County zoning permits, issued before the town building permit for new construction, additions and expansions
- Sanitary permits for new residential construction on private systems, and septic evaluations for additions to existing structures
- Stormwater, erosion control and illicit discharge permits under county ordinance
- Land division approvals under the county land division ordinance
- Conditional use permits, at a published county fee
- The town building permit, issued by the township after the county's approval
Often exempt
- Decks, balconies, pools and fences — from the foundation survey requirement, though zoning permits may still apply
- Anything inside an incorporated city or village, which is outside county jurisdiction
- Buildings used for farming — exempt from the state code under Wis. Stat. 101.05(5), with farming defined by DSPS rule; a produce stand stays exempt only while the farmer raised substantially all of what it sells
- Primitive rural hunting cabins — carved out of municipal jurisdiction by Wis. Stat. 101.65(1g)
- Bed-and-breakfast establishments as defined by statute (Wis. Stat. 101.05(2))
What is actually local, and what is not
The building code is statewide; the county controls siting. Zoning district classification, setbacks, environmental asset proximity and sanitation capacity are the county's questions, and the answers determine whether the town can issue at all.
Who handles permitting in Kenosha County?
Planning and Development, through its Division of County Development, issues zoning permits and administers sanitation and land conservation. Town building inspectors issue the building permits. The county recommends meeting with development staff before submitting a zoning application to discuss sanitation, access, building design and setback requirements.

Permit types
Residential permits
New residential construction needs a county zoning permit application with a stake-out survey and construction drawings including floor plans and elevations, plus the appropriate fee. A sanitary permit is needed where the lot is on a private system; additions may need a septic system evaluation instead. After construction, the updated plat of survey closes the file.
How Wisconsin contractor licensing works
Wisconsin has no state general contractor license for commercial work — the city's own forms note that 2013 Wisconsin Act 20 ended state building-contractor registration on July 2, 2013. For one- and two-family work the state requires a Dwelling Contractor certification on the business and a Dwelling Contractor Qualifier on an individual, and under Wis. Stat. 101.65(1m) Kenosha County may not issue a building permit to a contractor who cannot produce them; owner-occupants are exempt. Electricians and plumbers are licensed statewide by DSPS. HVAC contractors only register with the state — there is no state HVAC license — which is exactly where local rules step in. Kenosha County licenses no trades; state credentials govern and the town building inspector verifies them.
Commercial permits
New commercial, manufacturing and institutional construction follows its own published county procedure, with conditional use permits available for uses that need them at a published fee. Building code plan review routes to the state or a delegated municipality; the county holds no commercial plan review delegation.
Mechanical work, and where the state reviews directly
Commercial plan review in Wisconsin is a two-step: under Wis. Stat. 101.12(3)(h) the plan approval comes first and the local permit cannot issue without it. The state review trigger is 25,000 cubic feet, plus categorical triggers at any size for schools, high-hazard occupancies and residential buildings of three or more units. At 50,000 cubic feet plans must be prepared, signed and sealed by a Wisconsin-registered design professional, with a supervising professional retained for construction observation. Commercial plumbing plans go to review at sixteen or more fixtures. Applicants also complete obligations for the foundation survey, waiver of liability where applicable, stormwater as-built requirements and any certificate of occupancy conditions.
Kenosha County permit costs and fees
County fees follow the Planning and Development fee schedule, and the penalty for starting early is among the steepest in the state.
| Item | Fee or rule |
|---|---|
| Zoning permit | Per the county fee schedule, by project type |
| Conditional use permit | Published county fee, in the hundreds of dollars |
| Work started before permitting | Triple fees, per the county's own statement |
| Minor structures | Zoning permits for decks, fences and outbuildings generally issued immediately, first come first served |
| Town building permit | Set by the township |
Triple fees for starting early. The county states plainly that triple fees shall be charged if work has started prior to applying for the appropriate permit — matching the sharpest municipal penalty in the state.
Trade permits and who may pull them
Trades are state-credentialed and permitted at town level; sanitation work runs through the county sanitarian.
Permit required
- Electrical, plumbing and HVAC — state credentials; town permits
- Private sewage systems — county sanitary permit; contact the County Sanitarian at Planning and Development
- Land disturbance — county stormwater and erosion control permits
- One- and two-family general work — state Dwelling Contractor plus Qualifier
Typically exempt
- Minor structures for the survey requirement — decks, balconies, pools and fences
- Work inside cities and villages, which follows municipal rules
How to apply for a Kenosha County building permit
Brighton, Paris, Randall, Somers or Wheatland; call the county with a tax key number if unsure.
The county recommends it, to settle sanitation, access, design and setbacks.
With stake-out survey or site plan, floor plans, elevations and the fee.
New construction on a private system needs the permit; additions may need an evaluation.
Only after the zoning permit is issued.
A Wisconsin professional surveyor updates the plat by the date printed on the zoning permit.
Review, corrections and what actually causes delay
Minor structures move fast — deck, fence and outbuilding zoning permits are generally issued on the spot. New construction moves at the pace of the sanitation answer, which is why the county pushes a pre-application meeting.
Inspections in Kenosha County
