Acreage near Springfield

Springfield itself is built out into neighbourhood lots, so most barndominium owners here buy acreage in unincorporated Sangamon County or in neighbouring Christian and Menard counties. A rural parcel usually means a private septic system and well, which the Sangamon County Department of Public Health permits.

Building in Springfield: common questions

Who builds barndominiums in Springfield, Illinois?
We do. We supply barndominium kits and custom plans and run turnkey builds for owners in and around Springfield, Illinois. Start with the free land survey form: tell us where your parcel is and how you want to live and work in the building, and we will come back with a plan, a build sequence and a price range.
Do I need a building permit for a barndominium in Springfield, Illinois?
Yes. Inside the city limits, new homes are permitted by the City of Springfield's Building and Zoning division, which lists the 2018 International Residential Code among the codes it uses. On land outside the city, Sangamon County's Building Safety Section reviews plans and issues the permit. A barndominium you live in is a house, not an agricultural-exempt building.
How much does a barndominium cost near Springfield?
It depends on the floor area, the shop-to-living split, the finish level and how much site work the land needs, such as a driveway, septic system and well. We do not quote a flat number before we know your parcel; the survey lets us price your building on your land.
Can I build a barndominium on acreage in Sangamon County?
Usually, yes, subject to county zoning and a building permit. Rural parcels normally need a private septic system permitted by the Sangamon County Department of Public Health, which requires a soil assessment by a licensed soil scientist, so budget time for that before construction.
Can I buy a barndominium kit and have you finish it?
Yes. We supply kit packages for owners who want to manage part of the work, or take the build turnkey from foundation to finishes. The metal roof is installed by a licensed Illinois roofing contractor, and plumbing by a licensed Illinois plumber.
