Kenosha is unusually explicit about dates and thresholds. The Building Inspection page states the city has adopted the 2021 International Building Code as of November 1, 2025 and tells commercial submitters to align plans with it; the accessory-building line sits at one hundred twenty square feet in residential zones; and occupancy for a new business takes four inspections after the application clears.
The Department of City Inspections operates from Room 100 of the Municipal Building at 625 52nd Street, handling plumbing, electrical, mechanical and structural permitting and inspections for the city, with over-the-counter issuance available for routine residential electrical and HVAC permits.
This guide covers the City of Kenosha. Pleasant Prairie, Somers, Bristol and the rest of the county permit separately — several towns and villages through their own inspectors — and Kenosha County's development office in Bristol is a different authority entirely.
Two rules straight off the city's page. First, the code date: the 2021 IBC applies, adopted as of November 1, 2025 — submit commercial plans to the 2021 editions. Second, a Kenosha-specific enforcement note on commercial HVAC: all exhaust and intake plastic pipe must comply with UL1738; residential HVAC is expressly not subject to it.
What requires a building permit in Kenosha?
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 may not enforce different technical standards — local ordinances must strictly conform to the state codes.
Typically permit required
- New buildings, additions, alterations and change of use on both tracks
- Any accessory building over one hundred twenty square feet in residential zones — and of any size in every other zoning district, under ordinance 9.06 H.1.(a)
- Plumbing, electrical and mechanical work under separate trade permits
- Exterior sewer and water lateral work — plus a Street Opening Permit from Public Works when the work enters the right-of-way
- Razing a garage or shed of five hundred square feet or greater, which takes a raze permit packet
Often exempt
- Accessory buildings of one hundred twenty square feet or less in residentially zoned areas
- Ordinary repairs that do not alter structure or systems
- 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
Kenosha's technical standards are the state's — what the city adds is calibration. The one hundred twenty square foot accessory line, the UL1738 pipe rule on commercial HVAC, the four-inspection occupancy sequence and Chapter 9.07C penalty fees are the local layer; the codes underneath are SPS 320 to 325 and SPS 361 to 366 as adopted statewide.
Who handles permitting in Kenosha?
The Department of City Inspections issues permits and inspects; the Director of Inspections leads the office. Kenosha holds second-class-city delegation covering commercial buildings of all sizes and contracts plan review to E-Plan Exam per the state's roster. The city's own forms note that for buildings over fifty thousand cubic feet, plans must be reviewed by the state or a delegated agent under Wis. Stat. 101.12.

Permit types
Residential permits
Houses run on the Uniform Dwelling Code with permits from Room 100; routine residential electrical and HVAC permits can typically be submitted, paid and issued over the counter in one visit. A property owner acting as their own general contractor signs the city's Cautionary Statement in place of the Dwelling Contractor certification; hired general contractors on one- and two-family work must carry the state certification and qualifier.
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 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 adds no municipal trade license — and its own licensing form is the rare city document that cites the reason for the commercial gap, noting that 2013 Wisconsin Act 20 invalidated state building-contractor registration effective July 2, 2013.
Commercial permits
Commercial plans go to the 2021 editions — the city page says so with a date — and route through the city's all-size delegation with E-Plan Exam reviewing. The city's application materials restate the statutory split: over fifty thousand cubic feet, review by the state or a delegated agent; the city can perform commercial plumbing plan review where required.
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. Kenosha's own enforcement note adds a product standard on top: commercial HVAC exhaust and intake plastic pipe must comply with UL1738, a requirement the city expressly does not extend to residential systems.
Kenosha permit costs and fees
Kenosha publishes clean, split fees. A new accessory building prices at one hundred eighty dollars, itemized as sixty dollars each for the building permit, plan review and zoning review; repair to an existing accessory structure is sixty dollars.
| Item | Fee or rule |
|---|---|
| Accessory building, new | One hundred eighty dollars — sixty for permit, sixty for plan review, sixty for zoning review |
| Accessory building, repair | Sixty dollars |
| Unpermitted work | Penalty fee charged under Chapter 9.07C of the Code of General Ordinances |
| Occupancy, business or shell | Application approval followed by four required inspections before issuance |
| Trade permits | Per the current schedule; routine residential electrical and HVAC issue over the counter |
Occupancy is a sequence, not a stamp. A business occupancy or a new shell building takes four inspections after the application is approved before the occupancy issues — build the timeline around it.
Trade permits and who may pull them
Trades are state-credentialed. Exterior sewer and water lateral contractors and interior plumbing contractors must hold the state Master Plumber license; electrical and HVAC follow the state scheme, with the city issuing the permits.
Permit required
- Plumbing and laterals — state Master Plumber license; Street Opening Permit added in the right-of-way
- Electrical — state license; city permit, often over-the-counter for residential
- HVAC — state DSPS registration; UL1738 pipe compliance on commercial systems
- One- and two-family general work — state Dwelling Contractor plus Qualifier, or the owner's signed Cautionary Statement
Typically exempt
- Owner-occupants on their own one- or two-family dwelling, with the Cautionary Statement signed
- Like-for-like maintenance below permit triggers
How to apply for a Kenosha building permit
Pleasant Prairie, Somers and the county's Bristol office are different authorities.
One hundred twenty square feet is the residential-zone line; other districts permit at any size.
Commercial plans align to the 2021 IBC per the city's page — dated November 1, 2025.
625 52nd Street, Room 100; bldgpermits@kenosha.org; routine trade permits issue over the counter.
Lateral work in the street takes a Public Works Street Opening Permit alongside.
Business and shell occupancies sequence four inspections after approval.
Review, corrections and what actually causes delay
Kenosha's review runs cleanly when the plans match the stated editions; the recurring stumble since the change-over is 2015-era drawings resubmitted unrevised. On the residential side the desk moves fast — over-the-counter issuance for routine trade permits is the norm, not the exception.
Inspections in Kenosha
Trade and building inspections schedule through Room 100; erosion control has its own specialist. Occupancy for a business or new shell building requires four inspections following application approval before the certificate issues.
