Building permits, zoning and land rules in Wood County, Wisconsin

A UDC building permit is required for a new one- or two-family dwelling in Wood County, including stick-built, modular and manufactured-home installations¹. Wisconsin’s Uniform Dwelling Code sets construction standards and inspection procedures for these dwellings¹. The delegated municipality issues the building permit; where the municipality lacks authority, applications go to Wisconsin DSPS through eSLA¹. An owner who will occupy the home may apply without dwelling-contractor certification, but that exemption does not remove building-permit or inspection requirements¹⁰.

For a new home in unincorporated Wood County, the town usually holds the building-permit authority, not the county. Arpin, Auburndale, Dexter, Hiles, Milladore and Rudolph have a named UDC issuer or inspector⁵. Cameron, Cary, Grand Rapids, Hansen, Lincoln, Marshfield, Port Edwards, Remington, Richfield, Rock, Saratoga, Seneca, Sherry, Sigel and Wood are listed by DSPS as delegated, so the town is the permit authority, but we could not confirm who currently inspects there; ask the town clerk or use the DSPS Inspector Look-Up Tool^1,5. The county does not take over those permits⁵. Inside the cities and villages, Biron issues its own building permits through the Building Inspector, Nekoosa through its Building Inspector, and Pittsville through the city clerk-treasurer^11,12,13. Septic permits stay with Wood County Planning & Zoning for every address, city or not³. Required new-home inspections cover footings, foundation and reinforcement, rough work, insulation, and final inspection; notify the inspector named on the UDC permit¹.

Wood County administers its 1934 general zoning ordinance, plus shoreland and floodplain zoning, in unincorporated areas; 12 of its 22 towns have adopted their own zoning ordinances, and in those towns the town, not the county, administers and enforces zoning². Shoreland rules apply especially within 300 feet of a river or navigable stream and within 1,000 feet of a lake, and county approval is needed before listed work there². County and town zoning maps are published separately, so identify the parcel’s administrator and district first². Biron and Pittsville have their own zoning inside municipal limits; septic permits remain with Wood County Planning & Zoning^3,14,15. In unincorporated Wood County shoreland areas, buildings generally need a 75-foot setback from the ordinary high-water mark, subject to exemptions and adjustments¹⁶. Sewered shoreland lots generally need 10,000 square feet and 65-foot average width; unsewered lots need 20,000 square feet, 100-foot average width and 100 feet of shoreline frontage, with conditional provisions for existing substandard lots¹⁶. Town ordinances set their own dimensions. In the Town of Lincoln's R-1 district, lots need 1.5 acres and a 100-foot average width, with 200 feet of frontage (125 feet with public sewer and water)¹⁷. Lincoln R-1 buildings sit 25 feet from side and rear lines, and 75 feet from the centerline or 42 feet from the right-of-way of a town or county road, whichever is greater¹⁷. The Town of Grand Rapids requires a minimum ground floor of 400 square feet per dwelling unit in its R-2 and R-2S districts¹⁸. Other towns can add restrictions: the Town of Marshfield agricultural district specifies a 100-foot water setback and also directs applicants to county shoreland and floodplain rules¹⁹.

Wood County Planning & Zoning regulates and inspects septic systems and issues sanitary permits countywide, under the Wisconsin Uniform Plumbing Code and Wood County Ordinance #702³. The plumber responsible for the installation must request the inspection, which checks the work against the sanitary permit and state plumbing code⁸. A sanitary permit is required for septic installation, repair or alteration; the application needs the form, soil report, approved plans, any required holding-tank agreement and fee⁸. Wood County must issue the appropriate sanitary permit before construction, work or a change of use begins on a structure designed for human habitation or requiring private wastewater treatment²⁰. Holding tanks are permitted individually only when no other private onsite wastewater system can be installed⁸. Only about 0.6% of county soils are rated without severe conventional-drain-field limits, so establish septic feasibility before committing to a home site²¹. If approved public sanitary sewer becomes available, an existing private system or holding tank must be disconnected and the premises connected within one year²⁰.

We could not confirm a countywide rule for private-land RV living, temporary camping or tiny-home occupancy in Wood County; ask the applicable town zoning office or Wood County Planning & Zoning². One town shows how strict a local rule can be: in the Town of Rock, a travel trailer or motor home may be located only within a travel trailer park licensed by the Town Board, though a mobile home may be occupied temporarily on a residential lot during construction of a primary dwelling²². The answer can vary because zoning administration may belong to Wood County or the town². A manufactured home installed as a new dwelling falls within the statewide UDC program, while local zoning and land-use requirements may still apply^1,23. For an off-grid project with plumbing, Wisconsin still requires an approved way to treat, disperse, recycle or hold wastewater²⁴.

1. Identify the municipality and the zoning administrator for the parcel².

1. Ask the municipality for its current UDC permit issuer and inspector; the municipality or its contracted inspection agency may perform those functions⁴.

1. Obtain the soil evaluation and Wood County sanitary permit before construction begins on a home requiring private septic²⁰.

1. File the completed UDC application, prerequisite approvals and plans with the delegated municipality or DSPS, as applicable^1,7.

1. Obtain county approval for driveway work in a shoreland or floodplain zone, or a WisDOT connection permit where access meets a state highway^2,25.

1. Start after permit issuance, then notify the permit's inspector when each required inspection is ready¹.

Before buying in unincorporated Wood County, identify the town and zoning district, then ask Wood County Planning & Zoning about shoreland or floodplain restrictions; county approval is required before covered development begins in those zones². Floodplain property may also face use restrictions and flood-insurance requirements². New lots or building sites of 10 acres or less fall under the county land subdivision ordinance in unincorporated areas: divisions creating four or fewer lots need a Certified Survey Map, while five or more need a subdivision plat²⁶. A lot is not legally created until all approving authorities approve the map or plat and the instrument is recorded with the Register of Deeds²⁶. For subdivisions governed by the county ordinance, town-road building setbacks are the greater of 63 feet from centerline or 30 feet from right-of-way, unless zoning is more restrictive; separate standards apply along county and state highways²⁷.
