Building a barndominium in Warren County

We are barndominium builders for Warren County, the growth county between Cincinnati and Dayton. Families move here for the I-71 and I-75 access and then want more room than a subdivision lot gives them. We build turnkey barndominiums, supply barndominium kits for owner-builders, and put up pole barn homes and shouses with a shop, horse barn or equipment bay built into the same frame.

The southwest of the county, around Mason, Deerfield and the Route 42 corridor, is suburban now. The land is further east and north. Washington, Harlan and Massie townships, out past Lebanon and toward Morrow, Pleasant Plain, Butlerville and Harveysburg, are the least crowded parts of the county, with farm ground, woods and rural lots big enough for a house and a shop. Union Township around Lebanon and Salem Township near Morrow and Corwin fill in between. Warren County administers its own rural zoning in Franklin, Harlan, Turtlecreek, Union and Washington townships; elsewhere the county code does not apply and zoning goes through the township, so the lot-size and accessory-building rules depend on which side of a township line you buy. Warren County Building & Zoning in Lebanon reviews plans and inspects homes on unincorporated land and also serves several of the villages, and it publishes its own frost line, which we build to. Before you buy, we check the zoning, which department has the parcel and whether it needs septic and a well, then we quote the build for that land.

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 Warren County: common questions

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

Start your project

Do you build barndominiums in Warren County?

Yes. We build turnkey barndominiums, supply barndominium kits and put up pole barn homes and shouses across Warren County. Most of the acreage our clients buy is east and north of Lebanon, in Washington, Harlan and Massie townships, with Union and Salem townships closer in. Send us the parcel and we will tell you what it needs.

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

Yes. On unincorporated land, Warren County Building & Zoning is certified by the Ohio Board of Building Standards to enforce the Residential Code of Ohio, so a barndominium goes through plan review and inspections in Lebanon. A barndominium you live in is a dwelling, not a farm building. If the parcel is inside a certified city such as Franklin or Carlisle, that city's department handles it.

What frost depth do Warren County footings use?

Warren County Building & Zoning gives the frost line for its area as 30 inches below grade, and we set footings and foundations to that. The Residential Code of Ohio also sets a 115 mph design wind speed statewide, which matters on a tall, open-span building with big door openings.

Who handles zoning for a barndominium in rural Warren County?

It depends on the township. Warren County's own rural zoning code covers Franklin, Harlan, Turtlecreek, Union and Washington townships, so zoning approval comes from the county there. In the other townships, start at the township hall. Minimum lot size, setbacks and the rules for a large accessory building differ, so we check them before you close on land.

How much does it cost to build a barndominium in Warren County?

Land prices here reflect the growth, and the site work adds to it: clearing and grading, driveway length, a septic system and private well, the distance to power, and the interior finish level. A kit you finish yourself and a turnkey build land in very different places. Send us the parcel and a rough plan and we will quote it in writing.
