Barndominium Builders in Oshkosh, Wisconsin

Around Oshkosh, the first thing to pin down is which government your parcel answers to. The City of Oshkosh runs its own zoning and issues every permit inside the city limits. The Town of Oshkosh is a separate government, with its own contracted building inspector and its own zoning ordinance, and Winnebago County steps in on any lot within the shoreland area of Lake Winnebago or another lake or navigable stream. We design and build barndominiums for both situations: full turnkey homes, barndominium kits for owners who want to handle part of the work, steel-framed metal building homes, and pole barn homes on post-frame. A common request on acreage outside the city is a shouse, a shop with living quarters under the same roof, sized for boats, trailers and farm equipment. Barndominium contractors who know where the city line runs, which town the parcel sits in, and whether the shoreland boundary touches the lot keep the permit sequence short. Start the survey and tell us about your land, and we will lay out how the build would go on that site.

City or village permitWho issues the permit

City of Oshkosh Inspection Services (City Hall, 215 Church Avenue)

Winnebago County lists the City of Oshkosh among the incorporated places that keep their own zoning jurisdiction and issue all required permits, so a house inside the city goes through the city. Land in the Town of Oshkosh is different: the town's contracted inspector issues the building permit, and Winnebago County handles shoreland, sanitary and erosion control permits there.

City vs town zoning
Winnebago County's zoning office names four kinds of zoning jurisdiction. The City of Oshkosh is incorporated and issues its own permits; the Town of Oshkosh is one of eleven towns that keep their own zoning jurisdiction for zoning permits only, while the county keeps shoreland areas.

Town of Oshkosh inspector
The Town of Oshkosh changed its building permit process: from August 15, 2025, applicants apply directly to AJ Inspection Services LLC, which processes permit applications and conducts inspections by appointment. For a new home, the town says to submit the State DSPS new-home application first, then complete the town's own building permit application.

Shoreland in the Town of Oshkosh
The Town of Oshkosh states that Winnebago County keeps jurisdiction over shoreland areas, 1,000 feet from navigable waters, and that owners of property in the shoreland area apply to the Winnebago County Zoning Department rather than the town.

Sewer or septic
In the Town of Oshkosh, a property inside a sanitary district needs a lateral permit from that district to connect; a private onsite system needs a sanitary permit from Winnebago County. The county regulates all septic systems and holding tanks and became a delegated plan review authority for one- and two-family systems on August 28, 2019.

Private wells
Winnebago County does not regulate wells: its zoning office sends well questions to the Department of Natural Resources office in Oshkosh or to a licensed well driller. The Town of Oshkosh likewise points owners to DNR private well information.

Building on land near Oshkosh

Most acreage near Oshkosh sits in the surrounding towns, and each one draws the lines a little differently. The Town of Oshkosh sets its own zoning, while towns such as Algoma, Nekimi and Omro fall under county zoning. Near Lake Winnebago and the county's other lakes and rivers, shoreland rules add a county permit on top of the town's. Before you commit to a lot, check whether it lies inside a town sanitary district, which decides between a sewer lateral and a septic system, and whether a private well will be needed. Parcels in the other towns are covered on the [Winnebago County page](/areas/winnebago-county-wi/).

Building in Oshkosh: questions

Start the survey
How much does it cost to build a barndominium near Oshkosh?
Size, finishes, foundation type and the distance to sewer, water and power set the price, so we will not quote a number before we see a plan and a parcel. Our barndominium cost guide breaks the cost down line by line with third-party sources. On a rural lot, budget separately for a county sanitary permit and system, a well, and any shoreland permit.
Do I need a building permit for a barndominium in Oshkosh?
Yes. Inside the city limits, the City of Oshkosh issues the permits. In the Town of Oshkosh, the town's contracted inspector handles the building permit after the State new-home application is accepted, and a lot within the shoreland area also needs a Winnebago County permit. The credentialed dwelling contractor on your build applies for the permit.
Is the Town of Oshkosh the same as the City of Oshkosh?
No. They are separate governments with separate permit offices. The city issues its own permits for land inside its limits; the town governs land outside the city, keeps its own zoning ordinance and uses a contracted building inspector. Check the tax bill or the county parcel viewer to see which one your lot is in before you apply for anything.
Can I build a barndominium on Lake Winnebago shoreland?
Often, but Winnebago County sets the rules inside the shoreland zone, and its zoning office says wetlands cannot be filled regardless of size. Expect a county zoning permit alongside the town or city permit, and possibly a wetland delineation if the lot has unmapped wetland. Choose a plan that fits the buildable area; our floor plans can be narrowed or turned for a lakeside lot.
