Building in DeKalb County: common questions

Who builds barndominiums in DeKalb County?
We do. We supply barndominium kits, custom plans, pole barn homes and turnkey builds on acreage across unincorporated DeKalb County. Send us your parcel and we will return a scope, the permit steps and a price range.
Do I need a building permit for a barndominium in DeKalb County?
Yes. A barndominium used as a home is a dwelling, so in the unincorporated county it goes through DeKalb County Community Development under the 2021 International Residential Code. The agricultural exemption card covers farm structures, not houses. Inside a city or village, the municipality issues the permit.
Who approves the well and septic for a DeKalb County barndominium?
The DeKalb County Health Department issues water well and septic permits. Plan that review early, because the septic system's size and location shape where the house can sit on the lot.
How much does a barndominium cost in DeKalb County?
Size, finish level, foundation and site work (well, septic, driveway) set the price. We price each build against your parcel after a free survey rather than quoting a flat figure.
