Barndominium Builders in Dane County, Wisconsin

Dane County, Wisconsin draws more barndominium interest than any other county in the state's south-central region, and nearly all of it lands on town land: acreage outside the cities and villages, where the county's zoning code sets the district rules and the town handles the building permit. We plan and build steel-framed and post-frame barndominiums across Dane County, from finished turnkey homes to barndominium kits for owners who want to take on some of the work themselves. A common request is a single-family home on a few acres with a big shop bay, often set up as a shouse with the living space and the workshop under one roof. Rural parcels bring their own checklist. The zoning district decides whether a new residence is permitted outright or needs a conditional use, lots near lakes and streams need a shoreland permit, and nearly every country home needs a septic sanitary permit and a well location permit before anything else moves. Experienced barndominium contractors sort those approvals before the concrete is ordered, not after. Tell us about your land, or start the survey if you are still shopping for a parcel, and we will lay out how the build would run on that site.

Town-issued permitWho issues the permit

The town building inspector (or the town's contracted inspector), after a Dane County zoning permit

On town land, a new house starts with a zoning permit from the Dane County zoning division, which inspects the work, usually twice, and closes with a certificate of compliance. The county says the town where the parcel sits may also require its own building permit, so the town clerk confirms who inspects the house. Parcels inside a city or village go to that municipality instead.

Farmland preservation zoning: Dane County's FP-35 General Farmland Preservation district has a 35-acre minimum lot size. Residences that existed on Feb. 20, 2010 are permitted; a new farm residence is a conditional use, not a permitted one (Dane County zoning fact sheet, Chapter 10, section 10.222).
Rural residential lots: In the county's RR-4 Rural Residential district, one single-family home is permitted per parcel on a lot of 4 to under 8 acres, with buildings covering no more than 10% of the lot. A detached accessory building may not contain living space, and the house must exist or be under construction before an accessory building gets its zoning permit.
Farmland Preservation Plan: The Dane County Board adopted the 2022 Farmland Preservation Plan on Dec. 19, 2022, and the Wisconsin Department of Agriculture, Trade and Consumer Protection has certified it through Dec. 31, 2032. The county publishes town-by-town acreage limitations alongside the plan.
Shoreland zoning: Dane County treats land within 300 feet of a river or stream, or 1,000 feet of a lake or pond, as the shoreland zoning district. A new structure within 300 feet of navigable water needs a county shoreland zoning permit, backed by a plat of survey from a licensed surveyor showing the ordinary high water mark.
Floodplain administrator: The Dane County Zoning Division is the floodplain administrator for rural parts of the county. Building in a Zone A or AE floodplain requires a floodplain development permit under the county's Chapter 17 floodplain zoning rules.
Septic and well permits: Public Health Madison & Dane County issues sanitary permits for private septic systems after a soil evaluation by a certified soil tester and a design from a licensed professional, and it issues well location permits before a well is built. A separate well construction permit comes from the DNR.

Building on land near Dane County

Before buying acreage in the towns, look up the parcel's zoning on the county's Access Dane map. A rural residential lot generally allows one home by right, while much of the farmland sits in the FP-35 district, where a new house is a conditional use and each town's acreage limits apply. Check the shoreland and floodplain maps for any parcel near a lake, river or creek. Away from public sewer, budget time for a soil test, a septic design and a well location permit. Pole barn homes and metal building homes fit most rural residential lots once the setbacks and height limits are checked. For a lot inside the capital city, see the [Madison page](/areas/madison-wi/).

Building in Dane County: questions

Start the survey

How much does it cost to build a barndominium near Dane County?

The number depends on the plan, the finish level, the foundation, and how much site work the parcel needs for a driveway, septic and well, so we price it once we have seen both the plan and the land. The barndominium cost guide breaks each category down with third-party sources. On rural Dane County land, add the soil test and septic design to the early budget.

Do I need a building permit for a barndominium in Dane County, Wisconsin?

Yes. A new home on town land needs a county zoning permit first, and the town where the parcel sits may require its own building permit and inspections, so ask the town clerk. Inside a city or village, the municipality's building inspection office handles it. The credentialed dwelling contractor on the job applies for the permit, and our permitting service explains the sequence.

Can I build a barndominium on farmland in Dane County?

Sometimes. In the FP-35 farmland preservation district, a new farm residence needs a conditional use permit and the lot minimum is 35 acres, so many buyers rezone a smaller lot or buy land already zoned rural residential. Check the zoning and the town's acreage limits before you make an offer.

Can a shop with living quarters be my only building?

In the RR-4 rural residential district, a detached accessory building may not contain living space, so the living quarters have to be part of the house itself. A design that puts the home and the shop under one roof as the principal residence is the usual answer; our floor plans include layouts built that way.
