Building a barndominium in Madison County

Madison County sits just west of Columbus along I-70, and it is one of the places our clients go when they want real acreage without a long commute into the city. We build turnkey barndominiums for families moving out to the country, barndominium kits for buyers who want to finish the interior themselves, pole barn homes on post-frame, and shouses that give a farm or trade business a proper shop next to the house.

This is farm country first. Roughly four-fifths of the county's land is in farms, 763 of them averaging about 310 acres, which is why a 5, 10 or 20 acre split off a larger tract is a realistic purchase here. The county has grown modestly, about 4 percent from 2020 to 2024, with most of the change near West Jefferson, Plain City and the Franklin County line, while the townships around London and toward the Fayette and Clark county lines stay open ground. One thing makes Madison County simpler than most of its neighbours: it has countywide zoning, administered by the county for 13 of its 14 townships, so the rules for a rural lot are largely the same from one township to the next. Building permits are handled for the county by the Village of West Jefferson under contract, and septic and well permits come from Madison County Public Health. As barndominium builders working across Madison County, we confirm the zoning district, the setbacks and the septic site for your parcel before we fix the footprint.

Local facts for building in Madison County

Madison County is certified by the Board of Building Standards to enforce the Residential Code of Ohio, and it runs its building permits through the Village of West Jefferson under contract, so a new home goes through plan review, permits and inspections. The City of London is certified separately, so a parcel inside the city goes to London's own department.

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 Madison County: common questions

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

Do you build barndominiums in Madison County?
Yes. We are barndominium builders for all of Madison County: we build turnkey barndominiums, supply barndominium kits and build pole barn homes and shouses throughout the county. Most of our clients here are buying a split of farm ground in the townships around London or toward the Fayette and Clark county lines, where parcels are large and the traffic is light.
Do I need a building permit for a barndominium in Madison County?
Yes. Madison County is certified by the Ohio Board of Building Standards to enforce the Residential Code of Ohio, and it contracts with the Village of West Jefferson to process building permits, so a new home needs plan approval, permits and inspections. Inside the City of London, the city's own certified department handles it. You also need county zoning approval and septic and well permits from Madison County Public Health.
Is zoning the same everywhere in Madison County?
Largely, yes. Madison County has countywide zoning, and the county office administers it for 13 of the 14 townships, so lot-size, frontage and setback rules do not change every time you cross a township line the way they do in many Ohio counties. We still check the zoning district on your specific parcel, because agricultural and residential districts carry different requirements.
Can I find 10 or more acres for a barndominium in Madison County?
Often. About 79 percent of the county is farmland and the average farm is around 310 acres, so smaller splits off larger tracts do come to market. The best odds are away from the eastern edge near West Jefferson and Plain City, where growth from the Columbus side is pushing prices up.
How much does it cost to build a barndominium in Madison County?
It turns on the parcel as much as the building. Farm ground often needs a new well, a septic system sized to the health district's rules, a drive long enough to meet the setback, and sometimes drainage work on flat, heavy soil. The size of the home, the shell system and the level of finish account for the rest. Tell us about the land and the plan you have in mind and we will send a quote.
