Barndominium Builders in Leavenworth County, Kansas

Outside the city limits, Leavenworth County runs its own building permit desk. The county Planning and Zoning department issues building permits for the unincorporated area, and it also writes the wastewater system permits, administers the sanitary code and handles floodplain administration, so one office answers most of the questions a rural barndominium raises. Towns inside the county, such as Lansing, Basehor and Tonganoxie, keep their own planning and permit counters. We plan and build barndominiums, shop houses and post frame homes on acreage across Leavenworth County, Kansas, from a finished turnkey house to a steel shell that your own crew completes. Where the design calls for plumbing, electrical or HVAC, licensed trade contractors handle that work. The deciding factor out here is usually the wastewater system, not the building: parcel size and soil set whether a conventional septic field, an engineered system or a lagoon is allowed. Tell us about your land in the survey and we will map the county route for your tract before you commit to a floor plan.

County-issued permitWho issues the permit

Leavenworth County Planning and Zoning Department

On unincorporated land, Leavenworth County Planning and Zoning requires a building permit for any home, addition or accessory structure, pole barns included; buildings under 200 square feet are not regulated. A permit stays valid for one year. The applicant must be on the deed or file an owner authorization. Land inside a city is permitted by that city, not the county.

Source: Building Permit (leavenworthcounty.gov)

County permit scope: The county requires a building permit for homes, building additions and accessory structures such as pole barns and outbuildings anywhere in unincorporated Leavenworth County. Structures smaller than 200 square feet are not regulated, and a permit is valid for one year from issue.
Engineered septic under 2.5 acres: Leavenworth County Planning and Zoning states that an engineered waste disposal system is required on parcels of less than 2.5 acres, and may also be required on larger lots where the soil is poor.
Lagoon conditions: A lagoon (waste stabilization pond) is considered only when a septic tank and lateral field or an alternative system is not possible, on a tract of five acres or more with at least 300 feet of road frontage. No further subdivision of that tract is allowed.
One office for land use: The county department administers the zoning and subdivision regulations, the sanitary code and the floodplain development regulation for unincorporated Leavenworth County. People inside city limits (Leavenworth, Lansing, Basehor, Tonganoxie, Easton and Linwood) go to their own city.
County seat permits separately: Inside the county seat, the city inspections division issues its own building permits under the 2018 International Residential Code, which covers single-family dwellings and accessory structures there. That review is separate from the county process.

Building on land near Leavenworth County

Rural tracts in Leavenworth County are mostly unsewered; the county itself notes that a majority of households outside the cities rely on septic systems. That makes acreage the first design input. Below two and a half acres, plan on an engineered wastewater system; at five acres with enough road frontage, a lagoon becomes possible if a lateral field will not work. Check the county interactive map for zoning and flood zones before closing, since floodplain development rules apply on top of the building permit. Pole barn homes fit these bigger tracts well, and the extra ground leaves room for a detached shop, which needs its own county permit when it tops 200 square feet.

Building in Leavenworth County: questions

Start the survey

What does a barndominium cost to build in Leavenworth County?

Land work often decides the budget here: an engineered septic system on a small parcel, a long entrance drive or a lagoon on a bigger tract can outweigh differences in the shell. After that, the size of the living area, the finish level and the shop bay drive the price of metal building homes as much as the steel itself. Our barndominium cost guide lists sourced ranges, and the survey lets us price your specific tract.

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

Yes, on unincorporated land. The county Planning and Zoning department permits homes and accessory buildings, and it expects the applicant to be on the deed or to file an owner authorization form. If the land lies inside Lansing, Basehor, Tonganoxie or another city, that city issues the permit instead. Our permitting service assembles the package.

How many acres do I need for septic in Leavenworth County?

There is no single number, but the county draws two lines. Parcels under two and a half acres need an engineered system, and a lagoon is only considered on five acres or more with at least 300 feet of road frontage. The county keeps a list of approved septic installers and designers, and one of them should look at your soil early.

Can I buy barndominium kits for land in Leavenworth County?

Yes. We supply barndominium kits with drawings sized to the county permit review, and your own crew or one of the other barndominium contractors in the area assembles the steel or post-frame shell on site. Compare layouts in our floor plans before choosing a kit.
