Barndominium Builders in Beloit, Wisconsin

Beloit sits on the state line along the Rock River, and the land around it is a patchwork of city lots, town subdivisions and Rock County farm fields. That patchwork matters more than most buyers expect, because the City of Beloit and the Town of Beloit are two separate governments with separate permit desks. We build barndominiums on both sides of that line: turnkey post-frame and steel-framed homes, a shouse with the living space beside a heated shop, and barndominium kits for owners who plan to do part of the interior themselves. Metal building homes on a narrower footprint fit an infill lot inside the city; larger parcels farther out suit a wider plan with a drive-through bay. Inside the city, the first stop is Planning and Building Services, where a site plan has to clear the zoning ordinance before a building permit can be issued. Barndominium contractors who line up that zoning sign-off early keep the plan review from starting over. If you have land near Beloit in mind, tell us where it is and what you want on it: start the survey, and we will come back with how the build would run on that parcel and which office will review it.

City or village permitWho issues the permit

City of Beloit Planning and Building Services (City Hall, 100 State Street, third floor)

Inside the City of Beloit, the city's building inspectors review plans for every one- and two-family project, and a permit is required before construction begins. A new structure first needs site plan review and a Certificate of Zoning Compliance. The Town of Beloit is a different government: it issues its own zoning and building permits for town parcels.

Plan review in the city: City of Beloit building inspectors review plans for all one- and two-family projects; larger commercial work goes to the state or the city's plan review consultant. The city requires a permit before construction, alteration or moving any building, and takes permit applications by email to its permits address.
Zoning compliance first: The City of Beloit requires site plan review before a new structure is built. Its Planning Division checks the site plan against the zoning ordinance and issues a Certificate of Zoning Compliance, which then allows the building permit; a Certificate of Occupancy follows once the work is completed and inspected. Architectural review does not apply to buildings of one or two units.
New homes approved in 2025: The City of Beloit's New Housing Fee Report counts 26 new dwelling units approved in 2025, all one- and two-family or manufactured homes and no multifamily. Its fee schedule for new homes includes plan review, a state permit stamp and an erosion control inspection for one- and two-family construction.
Town of Beloit: Rock County lists the Town of Beloit as issuing its own zoning and building permits and administering its own rural addresses, unlike several Rock County towns where the county handles zoning. Driveways onto county highways still need a Rock County permit.
Septic outside the sewer area: Where a lot is not served by public sewer, Rock County Public Health reviews plans, issues permits and inspects the installation of each new or replacement septic system, and its maintenance program requires an inspection by a certified professional every three years.

Building on land near Beloit

Start by pinning down which government the parcel answers to. A city lot comes with a zoning district, sewer and a site plan review at Planning and Building Services. A parcel in the Town of Beloit goes to the town hall for both zoning and the building permit, and one in another town may split zoning and building between the county and the town. Past the sewer lines, the soil has to pass a test for a septic system and the house needs a private well. For town land across the rest of the county, see the [Rock County page](/areas/rock-county-wi/); for the city to the north, see [Janesville](/areas/janesville-wi/).

Building in Beloit: questions

Start the survey

How much does it cost to build a barndominium near Beloit?

It turns on the plan size, the finish level, the foundation and how much site work the lot needs before the slab goes in. We give a figure only after seeing the plan and the parcel. Our barndominium cost guide lays out each cost category with third-party sources; a rural lot adds a well and a septic system to the list.

Do I need a building permit for a barndominium in Beloit?

Yes. In the City of Beloit, a new house needs site plan review and a Certificate of Zoning Compliance, then a building permit after the city's inspectors review the plans, and a Certificate of Occupancy at the end. In the Town of Beloit, the town issues the zoning and building permits itself, so the process runs through the town hall instead.

Is the Town of Beloit the same as the City of Beloit?

No. They are separate municipalities with separate offices. The city's Planning and Building Services handles permits within city limits, while the town issues its own zoning and building permits for town parcels. Check the parcel's municipality on its tax bill or the county land records before you plan anything.

Do you build pole barn homes around Beloit?

Yes, on parcels where the zoning allows a house of that size and layout. A post-frame house is permitted and inspected as a dwelling, the same as a stick-built home. See our pole barn homes page for how we plan the frame, insulation and finish.
