A new home in Lincoln County, Wisconsin needs a Uniform Dwelling Code building permit, issued by the town or city if it has delegated authority and otherwise through Wisconsin DSPS1. County zoning applies only in the towns that adopted it, and unzoned towns still fall under county shoreland zoning2. Septic permits for every town come from Lincoln County Land Services34.

Do you need a building permit in Lincoln County, Wisconsin?
Yes. Wisconsin's Uniform Dwelling Code applies statewide to one- and two-family dwellings, including manufactured-home installations9. A UDC building permit is required for a new one- or two-family dwelling, including stick-built, modular and manufactured-home installations; a municipality with delegated authority issues the permit, while other applications go to Wisconsin DSPS1. Construction may begin only after plans are approved and the building permit is issued and posted, and permit requirements for additions and alterations vary by municipality10. Ask the applicable town or city whether an addition or alteration needs a building permit11. An owner who occupies or will occupy the home may apply without a dwelling-contractor certification, but the owner-builder allowance does not remove other permit obligations5. County zoning permits and septic permits are separate approvals from the UDC building permit4.
Who handles Lincoln County building permits and inspections?
The town or city with delegated UDC authority is the first contact for a Lincoln County building permit and construction inspections; where a municipality has no delegated authority, the application goes to Wisconsin DSPS1. The responsible building inspector depends on the town, so confirm the current inspector with the town clerk, using the county's municipal officials contact page11. Lincoln County Land Services is the separate contact for county zoning approvals, shoreland and floodplain questions, and septic permits; its office is at the Lincoln County Service Center, 801 N. Sales Street, Suite 103, Merrill, and the phone number is 715-539-10874. New one- and two-family dwellings require footing, foundation and reinforcement, rough, insulation and final inspections12. Occupancy follows a final inspection with no major health or safety violations; some municipalities also issue an occupancy permit13.
Does Lincoln County have zoning?
Lincoln County zoning applies only in the towns that adopted it: Bradley, Corning, Harding, King, Merrill, Russell, Schley, Scott, Skanawan, Tomahawk and Wilson2. The other towns are unzoned by the county, and they remain subject to Lincoln County shoreland zoning2. An unzoned town may still have its own rules, so ask the town clerk as well11.
County shoreland zoning covers unincorporated land within 1,000 feet of a lake, pond or flowage or within 300 feet of a river or stream14. In those shoreland areas, buildings must sit at least 75 feet from the ordinary high-water mark, and lots need at least 10,000 square feet with public sewer or 20,000 square feet without it1516. Development within the county's regulated floodplain requires a land-use permit, flood-safety review and compliance with the applicable floodplain standards17.
Lincoln County minimum lot size, ordinary setbacks, lot coverage and general building-height limits in the zoned towns could not be confirmed; ask Land Services which district and ordinance govern the parcel4.
How do septic permits work in Lincoln County?
Lincoln County Land Services reviews private onsite wastewater treatment system designs and issues sanitary permits, including in towns without county general zoning318. A sanitary permit is required for installation, construction, replacement or an addition to a POWTS, and the local permit depends on approved plan review19. POWTS plan materials include owner and project information, signed plans, supporting documents and the plan-review fee20. Inspection of POWTS construction and installation is required; follow the approval letter and contact the agency that issued the permit21. Mapped soils show 0% without severe limitations for a conventional drain field, so arrange a soil evaluation before fixing the house location8. Wisconsin requires private wastewater systems to be visually inspected at least once every 3 years22.
Can you live in an RV or tiny home on land in Lincoln County?
Lincoln County has not confirmed one countywide answer for living in an RV, temporary camping on an ordinary private parcel, or occupying a tiny home. Ask Lincoln County Land Services which zoning rules apply to the parcel, then ask the applicable town about any town-level ordinance before buying or placing a unit4. A separate rule applies to camping units in public or private campgrounds within regulated floodplain areas: a unit may remain on a site for no more than 180 consecutive days, must then leave the floodplain for at least 24 hours, and needs the campground operator's written authorization when it remains longer than 30 days6. Private campgrounds in county zoning districts are for nonpermanent overnight habitation and must have 4 or more camping units23. Neither campground rule answers whether someone may live in an RV on an ordinary private lot. A tiny home that qualifies as a new one- or two-family dwelling must follow the statewide UDC permit rules, and a private wastewater system requires county review243.
Building a home in Lincoln County: the steps, in order
- Ask Lincoln County Land Services to identify the parcel's zoning coverage and any shoreland, floodplain or land-use approvals425. Floodplain development requires a land-use permit and flood-safety review17.
- Ask the town clerk which building inspector and town permits apply11.
- If the home will use private wastewater, submit the owner and project information, signed plans, supporting documents and review fee, then obtain the sanitary permit after plan approval2019.
- Submit the UDC application, plans, required project data, contractor-license information when applicable, and fee to the delegated municipality or Wisconsin DSPS201.
- Notify the inspector identified on the UDC permit at each required inspection stage12.
- Occupy the home only after a final inspection finds no major health or safety violations; ask whether the municipality also issues an occupancy permit13.
What should you check before buying land in Lincoln County?
Start by checking the parcel on Lincoln County's zoning map because county zoning coverage varies by area, then separately check shoreland and floodplain jurisdiction2526. Development in a regulated floodplain requires a land-use permit and review for flood safety17. Test the proposed septic area early because mapped soils show 0% without severe limitations for a conventional drain field8. For a new private well, Wisconsin generally requires advance DNR notice; a high-capacity well capable of 70 gallons per minute or more instead requires written approval7. If access will connect to a state highway, WisDOT requires a connection permit27. Lincoln County is 80.3% wooded and 93.7% of its land is at a slope of 15% or less, but parcel-level timber, drainage and buildability still need on-site review2829.
Watch-outs
- A parcel in an unzoned town is not automatically unrestricted because county shoreland zoning, floodplain rules and town rules may still apply226.
- The floodplain campground rule does not settle RV living on an ordinary private parcel; ask Land Services and the applicable town before purchase64.
- Building permits, county zoning permits and septic permits come from three different offices, so confirm each one for the parcel14.
