Barndominium Builders in Mohave County, Arizona

We build barndominiums across unincorporated Mohave County: bolted steel shop homes, pole barn homes and full turnkey projects, and we ship barndominium kits to owners who want to raise the frame with their own crew. A lot of our Mohave work is on big, bare desert parcels in places like Golden Valley, Dolan Springs and the valleys around Kingman, where nothing is in the ground yet. That changes the order of the job. The county will not run power to vacant land or give it an address, so the first building permit is what brings electric onto the parcel, and any project with plumbing needs an approved septic system. Mohave County Development Services handles both the building permit and the septic permit, which keeps the paperwork in one office. For a steel barndominium the county wants stamped, engineered plans, and we draw to the wind and snow values it publishes for the elevation of your site. If you are comparing barndominium contractors for land in or near Mohave County, start the survey and tell us the parcel number; we check zoning, septic room and access before we price anything.

County-issued permitWho issues the permit

Mohave County Development Services, Building Division

On unincorporated land, Mohave County Development Services issues residential building permits through its online permitting portal, and its Planning & Zoning Division answers zoning and setback questions. The same department issues septic permits. Kingman, Lake Havasu City and other incorporated cities run their own building departments, so check the parcel's jurisdiction first: a Kingman mailing address does not mean the land is inside a city.

Tribal land: The Hualapai Tribe's reservation covers about one million acres along the Grand Canyon and the Colorado River, in parts of Mohave, Coconino and Yavapai counties. The tribal government has jurisdiction on its own land; county permits do not reach it.

Septic comes before plumbing: Mohave County's Residential page states that an approved septic system is required for all projects with plumbing. Development Services processes conventional and some alternative septic systems, from site investigation through construction authorization and discharge authorization, under authority the county says ADEQ has delegated to it.
Steel building plan requirements: For steel buildings, Mohave County asks for two full sets of engineered plans and calculations, one set wet-stamped, three sets inside the Strip. If the building package has no foundation plan, an engineer must design one, for a soil bearing pressure of 1,500 psf unless a soils report justifies a higher figure. Steel buildings are designed and inspected to AISC 360.
Published design values: The county's steel-building requirements list the 2018 International Building Code, a 95 mph basic wind speed (Risk Category II), exposure C and seismic category C. Ground snow load depends on elevation: zero up to 3,000 feet, 5 psf above 3,000 to 4,500 feet, and 10 psf above 4,500 to 5,400 feet.
Power and addresses on vacant land: Mohave County's building FAQ says no electric is permitted on vacant land; the first building permit applied for can provide electric to the property. The county also will not address vacant land: an address is assigned when a building permit is issued. Grading of 100 cubic yards or more needs its own permit.
Wells beside septic systems: The county's septic FAQ requires at least 100 feet between a septic system and a well, including a neighbour's system, recommends a 50-foot buffer between a well and the property line, and notes that current subdivision rules call for at least one acre. Where public water is not available, the septic system also keeps a 50-foot buffer to property lines unless neighbours record an agreement.
Hualapai Valley groundwater: Mohave County's water-information page tracks the Hualapai Valley Groundwater Basin Irrigation Non-Expansion Area, including ADWR's findings, decision and order dated 19 December 2022, and USGS studies of the Hualapai, Detrital and Sacramento valley basins.

Building on land near Mohave County

Cheap acreage is the draw in rural Mohave County, and it is usually raw. Before you buy, find out three things. How will the parcel get water: a private well, a shared well or hauled water? Is there room for a septic field with 100 feet to any well, yours or a neighbour's? And does the road in reach the lot, or does the last stretch cross a wash? A barndominium on bare land also waits on power, because the county ties electric service to the first building permit. Around the Hualapai Valley, the irrigation non-expansion area limits new irrigated farmland rather than a household well, but groundwater is watched closely there. We walk each parcel against these questions before we draw the pad.

Building in Mohave County: questions

How much does a barndominium cost in rural Mohave County?

On raw land the site often moves the number more than the building does. A well or water hauling, a septic system sized to the soil, a long power run and grading on a slope all land before the slab. We price against your parcel once we know where it is. For sourced per-square-foot ranges and the main cost drivers, read our barndominium cost guide.

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

Yes. A new home needs a residential building permit from Mohave County Development Services, and a steel building needs engineered, stamped plans. File the septic permit at the same time; the county recommends it so the system fits the setbacks from the new home. On turnkey builds we prepare the drawings and handle both applications. See our permitting service for the steps.

Do you sell kits for owners who build on their own land?

Yes. Many Mohave buyers order a kit and hire local trades for the slab and utilities. Our kits ship with the engineered drawings the county asks for, and we can size the frame to the snow value for your elevation. Compare the packages on our kits page, or look at metal building homes if you want us to finish the interior too.

Which parts of Mohave County do you serve?

The unincorporated county, including Golden Valley, Dolan Springs and the desert around it, plus Kingman and Lake Havasu City, which permit inside their own limits. We also work south in La Paz County. Tell us your parcel number in the survey and we confirm which office covers it.
