Barndominium Builders in Dallas County, Iowa

Dallas County, Iowa, the one west of Des Moines with county offices in Adel and Perry, is where many metro families look first for acreage. Between the towns there is still farm ground and rural-residential land with space for a shop, a few outbuildings and a long driveway. On unincorporated land the Dallas County Planning and Development department handles zoning and building permits, and it has a building inspector on staff. The county's Uniform Construction Codes ordinance adopts the International Residential Code for houses outside the cities and writes in local design figures, including a 30 psf ground snow load and a 42-inch frost line. That gives a steel or post-frame design a fixed target. The order of approvals matters here: the county wants the septic permit, trade sub-permits and any road entrance permit in hand before it issues the building permit, so we line those up early. We design, supply and build the house, and we coordinate the paperwork so the start date holds. For anyone weighing barndominium contractors near Dallas County acreage, the survey tells us where the land is and what you want to build on it.

County-issued permitWho issues the permit

Dallas County Planning and Development, Adel

On unincorporated land the county planning office takes building permit applications by email, mail or in person, not through the self-service portal. Dwelling permits need a site plan, full construction plans, a septic permit, trade sub-permits and any entrance permit before issue. Cities such as Waukee permit their own land.

Building on land near Dallas County

Rural Dallas County mixes working farm ground with smaller rural-residential tracts carved from it. Floodplain maps matter near streams, and the county notes that its zoning ordinance may still apply to structures in a floodplain even where land is farm-exempt. Most acreage relies on a private well and septic, and the soil analysis for the septic design often fixes where the house and shop can go. Pole barn homes suit this ground, and metal building homes with clear spans are common where a buyer wants equipment storage. We walk the site with the permit rules in mind, since the county wants all four property lines and setbacks drawn on the site plan.

Building in Dallas County: questions

Start the survey
How much does it cost to build a barndominium in Dallas County?
Budget the land work first: a soil analysis and septic design, a well, a county road entrance and a power run can add up before the frame arrives. We do not publish a rate of our own. Use our barndominium cost guide for sourced ranges, and send the parcel through the survey for a quote.
Do I need a permit to build a barndominium in Dallas County, Iowa?
Yes, on unincorporated land the county planning office issues a building permit, and for a dwelling it will not issue one until the septic permit and electrical, mechanical and plumbing sub-permits are in place. A true farm house on a working farm can apply for the agricultural exemption from county zoning, but the Director decides whether it qualifies.
Can I build post frame homes or barndominium kits in Dallas County?
Yes. The county asks for floor plans, foundation and footing details, truss plans and framing details with the application, so post frame homes and barndominium kits need a complete drawing set, not just a catalogue sheet. We prepare or review that set against the county's code figures. See post-frame homes.
Does land inside Waukee follow the county permit rules?
No. Inside Waukee the city Community Development Department issues building permits under the city codes. Our Waukee page covers that side; the county process described here applies to unincorporated land outside the corporate limits of the cities.
