Manitowoc County's general zoning ordinance carries a clean rule: no building or structure may be erected, moved, established, located or structurally altered until a zoning and setback permit has been issued. The town's building permit follows once the county's is in hand.
The Planning and Zoning Department, created in 1959 by county board resolution, provides planning services under state statute and administers the county's Chapter 8 general zoning ordinance, the sanitary programme for private sewage systems, and shoreland regulation.
This guide covers unincorporated Manitowoc County under county zoning. The City of Manitowoc, Two Rivers, Kiel, Reedsville, Mishicot and Valders permit their own construction, and each town issues its own building permits.
The county permit precedes the town's. Towns across the county publish the same sequence: resolve zoning, then obtain the county zoning and setback permit and a sanitary permit if required — an accurate site plan is needed for both — then take the driveway or culvert permit and, finally, the town building permit on the Wisconsin uniform building permit application.
What requires a building permit in Manitowoc 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), Manitowoc County may not enforce different technical standards — local ordinances must strictly conform to the state codes.
Typically permit required
- County zoning and setback permits before any structure is erected, moved, established, located or structurally altered
- Sanitary permits before installing, locating, moving, reconstructing, extending, enlarging, altering, converting or modifying a private sewage system, or changing the land use connected to it
- Sanitary permits for adding bedrooms to an existing dwelling, which changes system loading
- Shoreland approvals where applicable
- Driveway or culvert permits — from the county highway department on a county highway, or the town road superintendent on a town road
- The town building permit
Often exempt
- Exterior landscaping, which requires no permit
- Anything inside a city or village, which permits independently
- 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
Building standards are statewide. Manitowoc County's layer is Chapter 8 general zoning with its setback regime, and the sanitary ordinance, which reaches further than most — a bedroom addition alone triggers a sanitary permit because it changes the system's design loading.
Who handles permitting in Manitowoc County?
The Planning and Zoning Department issues zoning and setback permits, sanitary permits and shoreland approvals. Town building inspectors issue building permits, several of them named individuals contracted by the town. Conditional use, variance and zone change requests require an on-site inspection and a public hearing, and the process takes several months.

Permit types
Residential permits
A rural house needs the county zoning and setback permit with an accurate site plan, a sanitary permit where a private system is involved, a driveway or culvert permit, and then the town building permit using the Wisconsin uniform building permit application. Adding bedrooms to an existing house requires its own county sanitary permit.
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) Manitowoc 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. Manitowoc County licenses no trades; state credentials govern and the town inspector verifies them.
Commercial permits
Commercial development under county zoning needs the zoning and setback permit and any conditional use approval, which requires an on-site inspection and public hearing over several months. Town building permits for commercial work generally require state-approved plans to accompany the submittal. 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. Because sanitary permits attach to changes in land use connected to a system as well as to the system itself, a change of use in an existing building can trigger county review even without new construction.
Manitowoc County permit costs and fees
County permit fees are published by category and are separate from town building fees, which the towns set themselves and often price commercial work distinctly.
| Item | Fee or rule |
|---|---|
| Zoning setback permit — single family home, mobile home, cottage or addition | Published county fee, in the low hundreds of dollars |
| Zoning setback permit — accessory structures | Roughly half the single-family figure |
| Sanitary permit | Required for system work and for bedroom additions |
| Town building permit | Set by the town; towns commonly price commercial work separately and may limit permit renewals |
Town permits expire and renew a limited number of times. Town ordinances in the county commonly make building permits valid for one year, renewable up to three times, after which a new permit is required — and failure to obtain permits can mean double fees, deconstruction of what was built, and a fine.
Trade permits and who may pull them
Trades are state-credentialed and permitted at town level; county permits cover siting and sewage.
Permit required
- Electrical, plumbing and HVAC — state credentials; town permits
- Private sewage systems — county sanitary permit for installation, alteration or a change in connected land use
- Bedroom additions — county sanitary permit, because system loading changes
- One- and two-family general work — state Dwelling Contractor plus Qualifier
Typically exempt
- Exterior landscaping
- Work inside cities and villages

Review, corrections and what actually causes delay
The county side is quick once the site plan is accurate; the slow path is any conditional use, variance or rezoning, which requires an on-site inspection and public hearing and runs several months. Plan those before the construction schedule is set.
