Barndominium Builders in Pottawatomie County, Kansas

Pottawatomie County, Kansas, sits between Manhattan and Topeka, and much of its rural land is still zoned A1 agriculture from the countywide zoning of 1972. The Planning and Zoning Office in Westmoreland issues building permits for site-built homes across the unincorporated county, and its first piece of advice is to call before you buy a tract, because acreage, water supply and zoning all decide whether a house can go there. We design and build barndominiums, shop houses and metal building homes for owners with land across Pottawatomie County, from Wamego and St. Marys to Onaga and the Green Valley area. Some owners want a turnkey build; others take one of our barndominium kits and put their own crew on it, with licensed trade contractors covering plumbing, electrical and HVAC. The Blue Township sewer district near Manhattan is the exception to the rural pattern: the county has adopted building codes there and licenses the contractors who work in it. Elsewhere the county permit, the septic health permit and the zoning check carry most of the weight. Start the survey with your tract and we will tell you what the county will ask for and which plan fits the land.

County-issued permitWho issues the permit

Pottawatomie County Planning & Zoning Office, Westmoreland

The county Planning & Zoning Office issues building permits on unincorporated land, along with floodplain management, addressing and plat review under the Unified Development Regulations. Adopted building codes apply in the Blue Township Sewer District/Green Valley area. Cities permit their own homes: Wamego requires a city permit for new houses and checks zoning just outside its limits.

Acreage for a house: The Planning & Zoning Office gives a general rule of 3 acres minimum for a house served by a rural or city water district with a private septic system, and 5 acres with both a private well and private septic, and asks buyers to contact the office before purchasing a rural tract.
Zoning: When countywide zoning was set up in 1972, the whole county was zoned A1 (agriculture) with a few exceptions; the county says building a single-family home may require rezoning, depending on the property's current zoning.
Farm structures: A building permit is needed for all site-built dwellings and accessory structures; agricultural structures also need a permit so the county can check floodplain placement and setbacks.
Building codes and licensing: Pottawatomie County has adopted building codes for the area known as the Blue Township Sewer District/Green Valley, adopted code amendments in 2023, and issues county general contractor and trade contractor licences.
Septic and wells: The county Environmental Health Division, run through Public Works, oversees the installation and use of private wastewater disposal systems and private water supplies, issues the health permit for a new-construction waste disposal system and registers system installers.
Wamego zoning area: The City of Wamego requires a city building permit for new homes, and says projects just outside the city but inside the Wamego Zoning Jurisdiction must check with the city on zoning, even though city building codes are not applied outside city limits.

Building on land near Pottawatomie County

Most rural land here carries agricultural zoning, so a homesite search starts with three questions: how many acres, where the water comes from, and whether the tract needs rezoning. A parcel on a rural water district can work at three acres with a septic system; add a private well and the county's general rule rises to five. The Big Blue and Kansas river bottoms bring floodplain checks, and the county reviews floodplain placement even for farm structures. Post frame homes and pole barn homes are a natural match for these tracts, with room for equipment, a shop and a family under one roof. Talk to Planning and Zoning, then order the soil evaluation, before you close on anything.

Building in Pottawatomie County: questions

Start the survey

How much does a barndominium cost in Pottawatomie County?

Budgets swing with the tract: a well and septic on five acres, a rural water tap on three, the driveway and any floodplain work all land before the building is priced. Finish level and shop size follow. Our barndominium cost guide sets out sourced ranges, and the survey lets us price against your parcel.

Do I need a building permit for a barndominium in Pottawatomie County?

Yes. The county requires a permit for every site-built dwelling on unincorporated land, issued by the Planning & Zoning Office in Westmoreland through its online portal. Inside Wamego or another city, the city issues it. Near the county line with Riley County, see our Manhattan page as well. Our permitting service explains how we prepare the application.

How many acres do I need to build a house here?

The county's general rule is three acres if a water district serves the tract and the house uses a septic system, and five acres with a private well plus septic. Zoning, access and floodplain can still rule a tract out, which is why the county asks buyers to check with Planning and Zoning before purchase. Tell us about your land and we will help you ask the right questions.

Can I buy a kit and use my own builders?

Yes. Many owners order a kit and bring in their own crew or other barndominium contractors, while others hire us for the whole job. If the site is in the Blue Township sewer district, ask the county whether your trades need its contractor licence. Browse our floor plans to find a size for your tract.
