Barndominium Builders in Sauk County, Wisconsin

Sauk County, Wisconsin takes in rolling farmland, wooded hills and lake frontage around Baraboo and the Wisconsin Dells, and buyers come here for acreage with a view as often as for farmland. We build steel-framed and post-frame barndominiums across Sauk County, from move-in-ready turnkey homes to barndominium kits for owners who want to finish part of the work themselves. A typical plan is a family home with a generous shop, and the shouse format, living quarters and workshop under one roof, suits the many buyers who need space for equipment, boats or a trade. Permits here come from two directions. The county's Land Resources and Environment office handles land use permits, shoreland and floodplain rules and septic sanitary permits, and applications now go through its online portal. The building permit for the house comes from the town, and several towns run their own zoning on top of the county's rules. Barndominium contractors who line those approvals up early avoid the most common delay: a town that will not issue its permit until the county has signed off. Tell us about your land, or start the survey if you are still looking, and we will explain how a build would run on that parcel.

Town-issued permitWho issues the permit

The town's building inspector, after Sauk County land use and sanitary approvals

Sauk County's Zoning Division issues land use and sanitary permits and enforces the shoreland, floodplain and septic ordinances; the town issues the building permit. DSPS has delegated UDC permitting and inspection to towns such as Sumpter, which uses a contracted inspector. The Town of Merrimac will not issue its building permit until the county approves the septic permit. Cities and villages issue their own.

County land use and septic permits: Sauk County's Land Resources and Environment Department, through its Zoning Division, permits, inspects and enforces the county's zoning, shoreland protection, floodplain, rural addressing and private onsite wastewater treatment (septic) ordinances. Land use and sanitary permits are now filed through the county's online OpenGov portal.
Shoreland permits: Sauk County repealed and recreated its Shoreland Protection Ordinance (Chapter 8) in 2019. The county's shoreland brochure lists a detailed plot plan with setbacks, written local driveway approval and signed floor plans for a land use permit, and states that erosion control plans are required for all land uses in the shoreland area.
Agricultural Enterprise Area: Sauk County says landowners in the Bear Creek, Dellona, Fairfield and Woodland townships can apply for a farmland preservation agreement on land inside an Agricultural Enterprise Area. The agreement keeps the land in agricultural use for 10 years in return for a farmland preservation tax credit.
Town-run UDC permits: In an April 29, 2024 letter, the Wisconsin Department of Safety and Professional Services confirmed the Town of Sumpter's jurisdiction over construction and inspection of new one- and two-family dwellings, delegating permitting and inspection to the town, and named Johnson Inspection LLC as the town's primary code enforcement contact.
Town of Merrimac house rules: The Town of Merrimac (the town, not the Village of Merrimac) runs its own zoning. In its Single Family Residential district a new home needs at least 1,000 sq. ft. of living area and a width of at least 20 feet, height is capped at 35 feet, and accessory buildings are not allowed on a lot without a primary residence.
County approval comes first: The Town of Merrimac states it will not grant a building permit until Sauk County has approved the private sewage (septic) permit, and will not issue a permit in the shoreland zone, which it describes as land within 1,000 feet of shoreline, until any required county approval is granted.

Building on land near Sauk County

When a parcel is sloped, wooded or close to water, the building pad, driveway and septic site usually decide the plan rather than the other way round. Start with the county GIS shoreland layer, then ask the town clerk whether the town has its own zoning code, minimum home size or limits on accessory buildings, because those rules differ from town to town. Plan for a soil and site evaluation before the septic permit, and expect an erosion control plan on any lot near a lake or stream. Pole barn homes and metal building homes suit most rural lots here once the town and county setbacks are met.

Building in Sauk County: questions

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

It depends on the plan, the finishes, the foundation and how much grading, driveway and septic work a hillside or lakeside parcel needs, so we quote after seeing the plan and the site. Our barndominium cost guide explains each cost category with third-party sources. On sloped lots here, put excavation and erosion control near the top of the early budget.

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

Yes. On town land you will need a Sauk County land use permit and sanitary permit, and a building permit from the town, whose inspector reviews and inspects the house. Some towns will not issue their permit until the county approvals are in place, so apply to the county first. The credentialed dwelling contractor on the job applies for the building permit; see our permitting service.

Can I build a barndominium near a lake or river in Sauk County?

Often, yes, but lots near water fall under the county's shoreland ordinance. Expect a land use permit with a detailed plot plan, signed floor plans and an erosion control plan, and check the town's own rules as well. Our site preparation service covers the groundwork these lots need.

Is there a minimum house size for a barndominium in Sauk County?

Some towns set one. The Town of Merrimac, for example, requires at least 1,000 sq. ft. of living area in its single-family district. Ask the town before choosing one of our floor plans, especially a compact one.
