Building a barndominium in Brown County

We build barndominiums across Brown County, Ohio, from Mount Orab and Fayetteville in the north down to Georgetown, Ripley and Aberdeen on the river. Our barndominium builders deliver turnkey steel and post-frame homes, shop houses with room for equipment or a hobby shop, and barndominium kits for owners who want to take on part of the work.

Brown County is open farm country. More than half the land is in farms, with 1,103 farms averaging 161 acres, and it is where Cincinnati buyers go when Clermont County runs short of the acreage they want. Mount Orab and the SR 32 corridor give the shortest drive west to the city. The central and southern parts of the county, around Georgetown, Sardinia and Ripley, have larger parcels, more farmland for sale and quieter roads. Lots of 5 to 50 acres are common, and many buyers want a shop, a barn and a house on the same ground, which a barndominium does in one building.

Rural Brown County means rural site work. Most parcels need a septic system and a well, many need a new driveway and some grading, and a new lot split goes through the county's subdivision review before you can build. The county building department reviews plans and inspects new homes under the Residential Code of Ohio. We plan the site, the permits and the building together so the schedule holds from the first survey to move-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 Brown County: common questions

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

Do you build barndominiums in Brown County?
Yes. We build turnkey barndominiums, shop houses and pole barn style homes, and supply barndominium kits, across Brown County, from Mount Orab and Fayetteville to Georgetown, Sardinia and Ripley. Most of our builds here are on farm acreage of 5 acres and up.
Do I need a building permit for a barndominium in Brown County?
Yes for a home. The Brown County Building Department is certified by the Ohio Board of Building Standards and covers one-, two- and three-family dwellings under the Residential Code of Ohio. It asks for two sets of plans, reviews them, issues the permit on approval and inspects the build, with inspections requested 24 hours in advance. A barndominium you live in is a dwelling, even on a working farm.
What do I need before building on a new lot in Brown County?
If the parcel is being split from a larger tract, the survey or plat goes through the county's subdivision regulations. A Technical Review Committee with the County Engineer, the Health Department, the Planning Commission and Soil and Water Conservation reviews it weekly. Septic and well permits come from the Brown County Health Department, and your township or village can tell you whether zoning applies.
How much does it cost to build a barndominium in Brown County?
Site work carries a lot of the weight here: a septic system and well on most parcels, a new driveway, grading, and power run to the building site. Building size and finish level do the rest. Send us the parcel and your plan and we will quote it in writing.
