Barndominium Builders in Yuma County, Arizona

We build barndominiums across unincorporated Yuma County, Arizona: on irrigated farm ground in the valley, on desert acreage away from the river and on edge-of-town lots. The work covers steel shop homes, pole barn homes, full turnkey builds, and barndominium kits for owners who want to erect the shell themselves. Outside the cities, the Yuma County Department of Development Services is the office that matters. Its Building Safety Division issues the construction permit a new home needs, its Environmental Programs Division reviews the septic system, and its engineering and flood control staff may review the same project, so a complete plan set clears faster than a piecemeal one. Land near a military air base is its own case: the county's zoning ordinance has a separate article for property near them, so we check that before a design is fixed. A steel barndominium with an insulated envelope and generous shade handles the low-desert summer, and a clear-span shop has room for farm equipment. If you are comparing barndominium contractors near Yuma County parcels, ask how they will bundle the septic design with the building plans. Use the survey to tell us about your land.

County-issued permitWho issues the permit

Yuma County Department of Development Services, Building Safety Division

In unincorporated Yuma County, the Building Safety Division issues building permits and inspects the work; the county's FAQ says a construction permit is needed for all new construction. Inspection requests made before 4:00 p.m. on a weekday get next-business-day service. Inside its limits, the City of Yuma issues its own permits.

Tribal land: The Cocopah Indian Tribe's reservation, established in 1917, covers about 6,500 acres and lies 13 miles south of Yuma. The tribal government has jurisdiction on its own land; county permits do not reach it.

Permit needed for new construction: Yuma County's Building Safety FAQ states that a construction permit is needed for all new construction, and in most cases for repairs, replacements and additions. Other divisions of Development Services, such as Engineering and Flood Control, may also need to review and approve a project.
Septic application package: Yuma County's Environmental Programs FAQ says an Environmental Health Plan Review application and a Sewage Disposal Permit application are submitted together. The submittal includes a site plan, a notice of intent to discharge, a justified design flow, a perc test or soil investigation report and an engineering design. Soil reports come from a private engineering firm.
Wells within 100 feet: The same FAQ says a septic application lists the number of bedrooms, the plumbing fixture units, any existing septic systems and any well locations within 100 feet. Water from an individual well can be tested by a local testing laboratory.
Land near military air bases: The county's Planning & Zoning FAQ refers questions about developing property near a military air base to the Planner on Duty and to Article VII of the Zoning Ordinance. Its building FAQ adds that a manufactured home in an airport noise zone needs proof of noise attenuation or a sound test.
Adopted building code: Yuma County's Building Safety Code Amendments page lists the county's amendments to the 2024 International Building Code as its amendments to the adopted codes.

Building on land near Yuma County

Rural Yuma County land comes in two main types. Farm parcels in the valley sit among working fields, while desert acreage away from the river may have no utilities at all. Off sewer, a home needs a septic system designed from a perc test or soil investigation, and any well within 100 feet goes on the application. Some parcels sit near an air base, where the zoning ordinance adds its own rules. Metal building homes on these lots go faster when the septic design, the flood review and the zoning check are done alongside the building plans instead of after them. We line those pieces up for you before we price the build.

Building in Yuma County: questions

Start the survey

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

On rural land the site costs are the swing factor: a septic system with its soil report and engineering, a well or a water connection, the power run and the pad. The steel shell is easier to predict. We price the whole project once we know the parcel. For sourced per-square-foot ranges, see our barndominium cost guide before you set a budget.

Do I need a building permit for a barndominium in unincorporated Yuma County?

Yes. The county says every new construction project needs a construction permit from Building Safety, and a home off sewer also needs septic approval from Environmental Programs. Engineering and flood control may review the same plans. On turnkey builds we prepare the drawings and coordinate each review; the permitting service page describes how.

Can you build on farmland outside Yuma?

Yes, where the zoning allows a home. We confirm the zoning district with the county first, then plan the pad, drive and utility trenches around the fields. Our site preparation service covers that groundwork. For a building inside the city limits, see our Yuma page; we also build north in La Paz County.
