Portage County sequences its permits tightly. A sanitary permit must be issued before a zoning permit can be issued for new homes and for additions that increase the number of bedrooms or disrupt the existing building sewer line — and only then does the town issue the Uniform Dwelling Code building permit.
The Planning and Zoning Department administers county zoning, shoreland and floodplain regulation and the sanitary programme from Strongs Avenue in Stevens Point, alongside Land and Water Conservation, which permits manure storage facilities, and the county's land information and GIS functions.
This guide covers unincorporated Portage County. Stevens Point, Plover, Amherst and Almond permit their own construction, and the Town of Hull's building permits are issued by Village of Plover building inspectors — an arrangement worth confirming before filing.
The septic answer comes first. A sanitary permit is required before a zoning permit can be issued for new homes and for additions that increase the number of bedrooms or disrupt the existing building sewer line. A licensed plumber submits the sanitary application; homeowners may apply themselves only for non-plumbing sanitary permits such as privies or outhouses.
What requires a building permit in Portage 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), Portage County may not enforce different technical standards — local ordinances must strictly conform to the state codes.
Typically permit required
- County zoning permits for construction in county zoning jurisdiction
- Sanitary permits, submitted by a licensed plumber, before the zoning permit on new homes and bedroom additions
- Stormwater plan review where an accessory building exceeds two thousand square feet in a residential district, for commercial development in any district, for any development in the commercial, industrial or planned development districts, or for new construction within three hundred feet of surface water or wetlands draining toward them
- Wetland permits for any activity in wetlands
- Property address assignment through the Town Clerk before construction on a new or vacant lot
- The town building permit, issued under the Uniform Dwelling Code
Often exempt
- Non-plumbing sanitary permits, which homeowners may apply for themselves
- 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 and enforced by the town. Portage County's layer is siting, septic and stormwater — and its stormwater triggers are unusually specific, catching large accessory buildings and any construction near surface water that drains toward it.
Who handles permitting in Portage County?
Planning and Zoning administers zoning, shoreland, floodplain and the sanitary programme. Land and Water Conservation issues county permits for constructing, installing or substantially altering animal manure storage facilities and transfer mechanisms. Towns issue building permits, and town clerks assign property addresses.

Permit types
Residential permits
A new home needs the sanitary permit first, then the county zoning permit, then the town building permit under the Uniform Dwelling Code with state Dwelling Contractor credentials. A property address must be assigned by the town clerk for any new or vacant lot, and a well notification number obtained from the state natural resources department before well construction.
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) Portage 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. Portage County licenses no trades; state credentials govern, and a licensed plumber must submit the sanitary permit application.
Commercial permits
Commercial buildings must have state approval for the building and for onsite waste treatment systems, and commercial development triggers stormwater plan review in any zoning district. County zoning approval precedes the town building permit as on the residential side; 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. Stormwater review is determined case by case, and the county asks applicants to call before submitting a zoning application to establish whether it applies.
Portage County permit costs and fees
County fees follow the published schedule, payable by card, cheque or cash. The scheduling constraint is the sanitary permit, which gates the zoning permit and therefore the whole sequence.
| Item | Fee or rule |
|---|---|
| Zoning permit | Per the county fee schedule, depending on the work proposed |
| Sanitary permit | Submitted by a licensed plumber; required before the zoning permit on new homes and bedroom additions |
| Stormwater plan review | Separate submittal where the stated triggers apply |
| Town building permit | Set by the town |
Large accessory buildings trigger stormwater review. A separate stormwater plan review is required for accessory buildings greater than two thousand square feet in any residential district, for commercial development in any district, and for new construction within three hundred feet of surface water or wetlands that drains toward them.
Trade permits and who may pull them
Trades are state-credentialed and permitted at town level; septic work runs through licensed plumbers under county permit.
Permit required
- Electrical, plumbing and HVAC — state credentials; town permits
- Private onsite wastewater systems — county sanitary permit submitted by a licensed plumber
- Wetland activity — wetland permits, with the county contacted alongside other agencies
- One- and two-family general work — state Dwelling Contractor plus Qualifier
Typically exempt
- Non-plumbing sanitary permits such as privies, which homeowners may apply for
- Work inside cities and villages

Review, corrections and what actually causes delay
The sanitary permit is the critical path in Portage County, since it gates the zoning permit, which gates the town's. Starting the soil test late pushes everything. Stormwater review, when triggered, adds a parallel submittal.
Inspections in Portage County
Building inspections are the town's under the Uniform Dwelling Code. County activity covers sanitary system compliance, zoning enforcement and stormwater.
