Building permits, zoning and septic rules in Outagamie County, Wisconsin

Yes. A Uniform Dwelling Code permit is required for every new one- or two-family dwelling in Outagamie County, including stick-built, modular, and manufactured-home installations¹. The enforcing agency depends on the parcel: a delegated municipality handles its own permits, while another delegated authority or the Wisconsin Department of Safety and Professional Services handles other locations¹. If public sewer is unavailable, Outagamie County requires the sanitary permit for the private onsite wastewater treatment system before construction begins and before the building permit can issue². New homes require inspections of footings, foundation and reinforcement, rough work, insulation, and the finished building; notify the inspector identified on the permit when each stage is ready¹. Occupancy can begin after a final inspection finds no major health or safety violations, but only some municipalities issue a separate occupancy permit⁶.

Outagamie County Development & Land Services administers county zoning and sanitary systems from 320 S. Walnut St., Appleton, WI 54911². For zoning questions, call the Zoning Administrator at 920-832-5046². For sanitary-permit questions, call the Code Inspector at 920-832-6032². A property owner cannot submit the sanitary application directly; a licensed plumbing contractor must apply electronically through CityView⁷. Outagamie County has no zoning jurisdiction or permitting authority inside any city or village, such as the City of Appleton⁸. Building permits are separate and depend on the parcel's municipality or other delegated enforcing agency, so identify the authority before submitting a Uniform Dwelling Code building permit application; the county sanitary permit still comes from Development & Land Services^2,9. Outagamie County publishes its Development and Land Services fees: a gravity-system sanitary permit is $675, a mound-system permit is $825, an erosion-control permit is $350, and starting development before permit issuance doubles the applicable fee⁵.

Partly. County general zoning applies in 13 of Outagamie County's 19 townships, while cities, villages, and some towns administer their own zoning, so parcel location determines which zoning office and ordinance apply². Black Creek, Hortonia, Greenville, Grand Chute, Kaukauna, and Buchanan administer their own town zoning codes, while the Town of Maine has no general zoning⁸. County-administered shoreland rules generally apply within 300 feet of navigable waters and in mapped shoreland-wetland areas, while floodplain rules apply in mapped flood-hazard districts and airport zoning applies near Appleton International Airport². State shoreland rules generally place buildings at least 75 feet from the ordinary high-water mark and cap height at 35 feet within that band^10,11. Inside a city or village, zoning approval comes from that city or village, not from the county⁸. Use the county's zoning ordinance and GIS zoning map to identify the parcel's district^2,8. In a township under county zoning, a single-family house or mobile home on its own lot in the AGD general agricultural district needs at least 24,000 square feet and 100 feet of lot width, with a 25-foot front yard, 30-foot rear yard and 20-foot side yards¹². A lot rezoned out of the AED exclusive agricultural district to build a residence must meet the same minimums and may not exceed two acres¹². In AED, a preexisting or accessory dwelling on its own parcel needs 24,000 square feet and 100 feet of width, with front and rear yards of at least 25 feet and side yards of at least 15 feet¹³. Near Appleton International Airport, airport zoning sets land-use and height limits that depend on the airport-zoning area². Outside county zoning, ask the town, city or village that zones the parcel.

When public sewer is unavailable, new construction in Outagamie County needs a private onsite wastewater treatment system, or POWTS, and Development & Land Services administers the county sanitary permit². The permit must be issued before construction begins and before a building permit can issue; it is typically required for a new or replacement system, a system change, or added use that increases wastewater flow². A licensed plumbing contractor—not the property owner—must submit the application electronically through CityView⁷. Published county fees are $675 for a gravity-system sanitary permit and $825 for a mound-system permit, with double fees when development starts before permit issuance⁵. Only 9.3% of county soils are rated free of severe limitations for a conventional drain field, so test the site before treating a rural parcel as buildable¹⁴. A holding-tank sanitary permit costs $950⁵. Wisconsin requires existing POWTS to receive a visual inspection at least once every 3 years¹⁵. A composting toilet or similar setup does not settle the wastewater question because buildings off public sewer still need suitable provision for wastewater from plumbing fixtures¹⁶. For a private well, Wisconsin law requires advance notice to the DNR before construction of a new well that is not high capacity, with a $50.50 notification fee and a Well Construction Report within 30 days; the source describes a notification, not a general county well permit¹⁷.

We could not confirm a countywide rule for RV occupancy, temporary camping, or tiny-home occupancy on private land in Outagamie County, so ask the zoning authority for the parcel before relying on any of those uses. The one county RV rule we found covers floodfringe areas: a mobile recreational vehicle that stays on site 180 consecutive days or more, or is not fully licensed and ready for highway use, must meet the county's elevation and anchoring requirements for manufactured homes¹⁸. County general zoning reaches 13 of the county's 19 townships, while cities, villages, and some towns apply their own rules². Wisconsin State Park System camping limits apply to state-park campsites, not private parcels in Outagamie County¹⁹. A manufactured-home installation is expressly covered by the Uniform Dwelling Code and requires a permit as a new dwelling, but local zoning still determines where that use may be placed¹. A covered dwelling may be occupied after its final inspection finds no major health or safety violations; some municipalities also issue occupancy permits⁶. For a tiny home with plumbing where public sewer is unavailable, the county's POWTS permit remains part of the path². Wisconsin also requires a state lodging permit when a home, cabin, or similar lodging is rented to tourists or transients²⁰.

1. Locate the parcel and identify whether county zoning or a city, village, or town ordinance applies².
2. Check the applicable zoning district, mapped floodplain, shoreland, and airport constraints before finalizing a house site².
3. If public sewer is unavailable, hire a licensed plumbing contractor to submit the POWTS application through CityView; the owner cannot apply directly^2,7.
4. Obtain the sanitary permit before construction and before seeking the building permit².
5. Apply to the municipality or other delegated authority responsible for the parcel for the Uniform Dwelling Code building permit^1,9.
6. If you own and will occupy the finished home, use the owner-builder path for the construction and erosion-control permit without Dwelling Contractor certification³.
7. Do not begin development before permits issue because Outagamie County applies double fees to early work⁵.
8. Before drilling a private well, give the DNR advance notice and file the Well Construction Report within 30 days of completion¹⁷.
9. Notify the inspector named on the permit for required inspections, including footings, foundation, rough work, insulation, and final inspection¹.

Start with wastewater feasibility: only 9.3% of Outagamie County soils are rated free of severe limitations for a conventional drain field¹⁴. Confirm the zoning authority and district because county general zoning covers 13 of 19 townships, several towns use their own codes, and the Town of Maine has no general zoning^2,8. Check mapped flood hazards before choosing a house site; county review is often required for buildings, additions, major remodels, fill, grading, excavation, drainage changes, crossings, and post-flood repairs in covered districts². If a future split matters, Outagamie County reviews land divisions for legal, buildable parcels with wastewater service and safe access, commonly through a Certified Survey Map or subdivision plat². The land is mostly gentle, with 98.8% at a slope of 15% or less¹⁴. Farmland averages about $7,559 per acre, the typical home value is about $346,594, and the effective property-tax rate is about 1.5% with a median bill near $3,580¹⁴.
