Building a barndominium in Miami County

We are barndominium builders for Miami County landowners and for Dayton-area families moving north along I-75. We build turnkey barndominiums, supply barndominium kits for owner-builders, and put up pole barn homes and shouses with room for a shop, equipment or livestock under one roof. Miami County is still farm country, with more than eleven hundred farms, and its population has kept growing as the Dayton metro spreads north, so buildable acreage is easier to find here than in the suburbs.

The land is spread across the county's twelve townships, from Monroe and Bethel near Tipp City to Newberry, Newton and Union around Covington, Pleasant Hill and West Milton, and Staunton, Springcreek and Washington outside Troy and Piqua. Miami County administers county zoning in eight of those townships, while Bethel, Brown, Elizabeth and Lostcreek zone themselves, so the first question on any parcel is whose zoning rules apply. Miami County's building department in Troy reviews and inspects residential work for the county's unincorporated land and publishes the frost depth and snow load we design to. The same Troy department also serves neighbouring Darke County, which helps buyers looking a little further west. Tell us where your land is, and we will help you sort out zoning, septic, well and permits before you buy or build.

Local facts for building in Miami County

Where buyers find land near Miami County

We build across these neighbouring areas too. Each has its own building department, zoning and health district, so check the page for the one your land is in.

The statewide rules, in brief

  • Ohio has one statewide residential code, the Residential Code of Ohio, adopted by the Board of Building Standards.
  • The Residential Code of Ohio sets a 115 mph design wind speed statewide. Frost-line depth and ground snow load are left to the local jurisdiction, so we design to the figures published where your land is.
  • Whether your build is plan-reviewed and inspected depends on whether a building department certified by the Board for residential work covers your land. We confirm which one does before anything is drawn.
  • A barndominium that people live in is a dwelling, not a farm building. In our reading, the agricultural exemption covers barns, not homes.

Building in Miami County: common questions

5 questions we get asked most often about building in Miami County. If yours is not on the list, ask it directly.

Do you build barndominiums in Miami County?
Yes. We build turnkey barndominiums, supply barndominium kits and put up pole barn homes and shouses across Miami County, from the townships around Tipp City and Troy to the farm country around Covington, Pleasant Hill and West Milton. Send us your parcel and we will tell you what it needs.
Do I need a building permit for a barndominium in Miami County?
On unincorporated land, Miami County's building department in Troy is certified by the Ohio Board of Building Standards to enforce the Residential Code of Ohio, so plan on plan review and inspections. A barndominium you live in is a dwelling, not a farm building. Some cities and villages in the county are certified themselves, and if your parcel is inside one, that department handles it. Zoning approval comes separately.
Is my land under county zoning or township zoning?
Miami County administers zoning in eight townships: Concord, Monroe, Newberry, Newton, Springcreek, Staunton, Union and Washington. Bethel, Brown, Elizabeth and Lostcreek townships run their own zoning. The difference matters for lot size, setbacks and how large a shop or accessory building you can put up, so we confirm it on your parcel first.
I'm also looking at land in Darke County. Is the process different?
The permit office is the same. Miami County's building department in Troy is listed as Darke County's residential building department as well, and it publishes a Darke County jurisdiction table showing which villages it covers. Septic and zoning are still handled locally in Darke County, so we check those on the parcel.
How much does it cost to build a barndominium in Miami County?
Most of the variation comes from the site and the finish: clearing and grading, driveway length, a septic system, a private well, the distance to power, and how finished the interior is. A kit you complete yourself costs very differently from a turnkey build. Send us the parcel and a rough plan for a written quote.
