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

Yes. New one- and two-family homes in Racine County fall under Wisconsin's statewide Uniform Dwelling Code, which covers stick-built, modular and manufactured-home installations¹. Apply to the municipality when it has taken on the work; otherwise the application goes to Wisconsin DSPS¹. New homes need footing, foundation and foundation reinforcement, rough, insulation and final inspections; notify the inspector named on the UDC building permit¹. Occupancy follows a final inspection that finds no major health or safety violations, and only some municipalities issue a separate occupancy permit; the exterior must be finished within 2 years after the permit is issued⁷. An owner-occupant may skip the dwelling-contractor certification by signing the owner-occupant attestation, which does not remove the permit or inspections³.

Inside Racine, the Village of Mount Pleasant, the Village of Raymond and the Village of Rochester, the municipality handles building permits^9,10,11,12. Racine County Development Services issues POWTS sanitary permits countywide, including inside municipalities, and zoning permits for unincorporated townships and the Village of Caledonia². The county office is at the Ives Grove Office Complex, 14200 Washington Avenue, Sturtevant, WI 53177; call 262-886-8440 or email rcpublicworks@racinecounty.gov¹³. For Village of Raymond zoning questions call 262-835-4426, and for Village of Caledonia zoning questions call 262-835-4451². Some municipalities do not use the state online system, so ask the municipality how to file the UDC application³.

Racine County Development Services administers general zoning in all unincorporated townships and issues zoning permits in the Village of Caledonia². Racine, the Village of Mount Pleasant and the Village of Sturtevant have their own zoning ordinances, so the county district standards below do not apply to parcels there^14,15,16. Racine County Development Services still issues sanitary permits countywide². In the county's A-2 general farming and residential district II, each family needs at least 40,000 square feet plus any acreage antipollution rules require, and the lot must be at least 150 feet wide⁸. In the R-8 planned residential district a one-family lot needs at least 8,000 square feet; the R-5 urban residential district (II) minimum is 7,200 square feet¹⁷. We could not confirm complete yard setbacks, minimum dwelling sizes, or agricultural exemptions; ask Development Services for the parcel's district and applicable standards².

Racine County Development Services issues private onsite wastewater treatment system (POWTS) sanitary permits throughout Racine County, while Wisconsin DSPS regulates the POWTS program^2,18. Plans are required for a new POWTS and for replacement or added treatment, holding, or dispersal components; approved plan review is a condition of the local permit¹⁹. Any building using private sewage must have its sanitary permit before any local permit is issued¹⁹. Inspection of POWTS construction and installation is required under the plan-review approval letter; arrange it with the agency that issued the permit¹⁸. Existing systems must also be visually inspected at least once every 3 years²⁰. USDA rates only 2.3% of Racine County's soils as "not limited" for conventional septic drain fields; that does not make septic impossible, but supports budgeting for site evaluation and potentially an engineered or alternative design²¹.

We could not confirm a general Racine County rule allowing or prohibiting RV or tiny-home occupancy on private land; ask Racine County Development Services about the proposed use and parcel's zoning district². In Racine County floodfringe areas, an RV must be on site for less than 180 consecutive days and be fully licensed and ready for highway use, or meet elevation and anchoring requirements²². A dwelling covered by the statewide UDC still needs a building permit, including a manufactured-home installation; that approval does not establish local permission to occupy an RV or tiny home^1,2.

1. Ask Racine County Development Services for the parcel's zoning and sanitary requirements, and the municipality where to file the building-permit application^2,3.
2. For a building using private sewage, complete POWTS plan review and obtain the county sanitary permit before any local permit^2,19.
3. Obtain county zoning approval where applicable, then submit the UDC building-permit application with contractor license numbers and expiration dates, legible scaled or dimensioned plans, required project data, and the application fee^1,2. An owner who occupies or will occupy the dwelling can complete the owner-occupant attestation without dwelling-contractor certification; building permits and inspections remain required³.
4. Apply to the delegated municipality or Wisconsin DSPS otherwise; start construction after plans are approved and the building permit is issued and posted^1,7.
5. Notify the UDC permit's inspector for footing, foundation, rough, insulation, and final inspections, and arrange POWTS installation inspection with the sanitary-permit issuer^1,18. Take occupancy only after a final building inspection finds no major health or safety violations⁷.

USDA rates only 2.3% of Racine County soils as "not limited" for a conventional drain field; septic may still be feasible, but a site evaluation and potentially an engineered POWTS belong in the purchase budget²¹. For a private well, obtain a Wisconsin DNR notification number before construction and submit a well construction report afterward; most work requires licensed well drillers and pump installers⁵. Floodplain development typically needs land-use and building permits: floodways prohibit new structures, wells, and sewage systems, while qualifying floodfringe structures need dryland access and a first floor at least 2 feet above base flood elevation⁶. Shoreland buildings generally need a 75-foot setback from the ordinary high-water mark²³. A driveway connecting to a state highway needs a WisDOT connection permit²⁴. Farmland averages about $9,656 an acre, and the median property-tax bill is about $4,071 a year²¹.
