Barndominium Builders in Marana, Arizona

We build barndominiums in Marana, on in-town lots and on the larger acreage at the edges of the town. Owners here usually want room for equipment, horses or a big garage, and a steel barndominium with a clear-span shop bay delivers that without interior posts. We run complete turnkey builds, and we also supply barndominium kits to owners who have their own crew lined up. Inside town limits, Marana's Development Services runs a one-stop counter where planners, building code examiners and engineering staff sit together, so zoning, drainage and plan questions get answered in one place. The town has adopted the 2024 International Residential Code for new applications, and our drawings follow that edition. Two things shape a Marana budget early: whether the lot is in a mapped floodplain, and who supplies its water. If you are sizing up barndominium contractors near Marana, ask each one how they will handle the floodplain use permit, because it runs alongside the building permit rather than inside it. Send us the parcel through the survey and we will check both before we sketch a floor plan.

City-issued permitWho issues the permit

Town of Marana Development Services (Building Safety)

For land inside Marana's town limits, the Building Safety staff in the town's Development Services department answer building code and permit questions and review residential plans, working from the One-Stop Shop at the Marana Municipal Complex. Marana is a town rather than a city, and a parcel just past its boundary goes to a different review office, so the parcel's jurisdiction is the first thing we confirm.

Tribal land: Marana lies in Pima County, where the county reports that tribal nation lands, the Tohono O'odham Nation among them, make up nearly half of the land area. On those lands the tribal government has jurisdiction, and town or county permits do not apply there.

One-stop development counter: Marana's Development Services says its One-Stop Shop, on the second floor of the Marana Municipal Complex, is staffed by town planners, building code examiners and engineering technicians as a single point of contact for new development. Building code and permit questions go to Building Safety; floodplain and geotechnical questions go to Engineering.
Adopted residential code: The Town of Marana lists the 2024 International Residential Code, adopted by Ordinance 2025.013, for all new applications received after 18 July 2025. Plans already in review before that date may stay on the earlier code cycle. The town kept the 2018 International Energy Conservation Code with local amendments.
Floodplain use permit: Marana's Need a Permit page notes that a structure located in a floodplain may need a floodplain use permit in addition to the building permit, and points owners to the town's Floodplain Management page for mapping.
Small sheds: The same Marana page says no permit is needed for a one-story detached structure of up to 200 square feet measured from the edge of the foundation. Anything larger needs a permit application and checklist, so a barndominium and any sizeable detached shop go through review.
Marana Water supply: Marana Water reports that ADWR granted the town a Designation of Assured Water Supply in 2024 totalling 15,353 acre-feet a year, the volume ADWR found it could reliably provide for the next 100 years. The utility says it used about 3,700 acre-feet in 2025, and that CAP water is about 15% of the designated portfolio.

Building on land near Marana

Land around Marana splits into lots with a water main at the road and acreage that does not have one. Marana Water publishes service-area maps for water and sewer, and a parcel outside them needs a well, a shared system or another provider, which changes the site budget. Washes cross a lot of this ground, so the floodplain map matters, and a pad in a mapped area may need to be raised. Pole barn homes and metal building homes on a bolted steel frame both suit these open parcels. We check the water map, the floodplain map and the zoning on Marana Maps before we price the slab.

Building in Marana: questions

Start the survey

What does a barndominium cost to build in Marana?

Your parcel sets much of the number. A lot on Marana Water with sewer at the street costs less to prepare than acreage that needs a well, a septic system and a raised pad. Once we know the land, we price the shell, the finish level and the site work separately. Our barndominium cost guide sets out sourced per-square-foot ranges and the factors that move them.

Do I need a building permit for a barndominium in Marana?

Yes. A new home inside the town needs a building permit from Marana's Building Safety, reviewed against the 2024 residential code the town adopted. If the lot is in a floodplain, a separate floodplain use permit may also be required. On a turnkey project we prepare the drawings and file the applications. See our permitting service for the steps.

Can I buy a kit and build it myself in Marana?

Yes. We supply the steel frame, the sheeting and the drawings the town needs for review, and your crew raises the building. The permit application is then yours. Many owners here pair a kit with our site preparation so the pad and drainage are ready before the delivery arrives.

Do you build outside the town limits?

We do. Much of the acreage around Marana is in unincorporated Pima County, and we also work in Tucson and north into Pinal County. Each has its own review office, and we confirm which one covers your land first.
