Barndominium Builders in Pinal County, Arizona

Unincorporated Pinal County is where our acreage builds happen: horse properties, desert parcels off a county road, and former farm ground being split into homesites. We build steel-framed barndominiums, pole-style homes and turnkey projects out here, and we supply barndominium kits to owners who have the equipment and the crew to stand a frame. Outside the cities and towns, the county's Building Safety Department does the plan review and the inspections, and its current adopted codes are the 2018 International Codes, including the 2018 International Residential Code. The same department also serves some towns under intergovernmental agreements, so a Pinal address does not tell you which office will review the plans; the parcel record does. Rural land here usually brings three county permits beyond the building permit: a septic permit from the Aquifer Protection program, a well review on smaller parcels, and a Floodplain Use Permit if any part of the lot is in a mapped floodplain. We line those up before the building plans are final. If you are comparing barndominium contractors near Pinal County acreage, ask each one how they sequence those reviews. Start the survey and give us the parcel number.

Pinal County Development Services, Building Safety Department (Florence)

Applications go through the county's Citizen Access Portal.

Adopted codes: Pinal County's Building Safety page lists its current adopted codes as the 2018 International Building Code, the 2018 International Residential Code, the 2018 mechanical, plumbing, fuel gas, fire and property maintenance codes, the 2017 National Electrical Code and the 2018 energy code.
Septic and well reviews: The county's Aquifer Protection program permits and inspects conventional on-site wastewater systems up to 24,000 gallons per day and alternative systems up to 3,000 gallons per day, and reviews well permit applications on parcels of 5 acres and smaller for referral to the Arizona Department of Water Resources.
Floodplain use permits: Pinal County's Flood Control District requires a Floodplain Use Permit before construction begins on any development in a floodplain. For a single-lot home it is applied for separately from the building permit, and the district notes that requirements such as elevating the building one foot above the base flood elevation may apply.
Minor land divisions: Pinal County reviews land divisions that create five or fewer lots, parcels or fractional interests, with one or more of them 10 acres or less, in unincorporated areas through its Minor Land Division process. Applications must be submitted online through the Citizen Access Portal.
Groundwater: the Pinal AMA: A.R.S. 45-411 established the Pinal active management area as one of the initial AMAs, made up of the Maricopa-Stanfield, Eloy, Aguirre valley, Santa Rosa valley and Vekol valley sub-basins. ADWR's management plan puts it at about 4,000 square miles, taking in portions of Pinal, Maricopa and Pima counties.

Building on land near Pinal County

Pinal County acreage looks simple on a listing and rarely is. Check the zoning on the county's GIS map first, because it sets the setbacks, the animals you can keep and whether a parcel can be split. A split into five or fewer lots goes through the county's Minor Land Division review, and the zoning, the acreage and any earlier divisions decide whether it qualifies. Water comes next: a large part of the county lies in the Pinal Active Management Area, and a rural lot may depend on its own well. Then wastewater and washes: most rural parcels need a septic permit, and a floodplain adds its own county permit. Metal building homes on open desert ground also need an all-weather drive for trucks, so we plan the access road with the pad.

Building in Pinal County: questions

Start the survey

What does a barndominium cost on Pinal County acreage?

Rural land adds costs a city lot does not have: a well or a water connection, a septic system, a long driveway and sometimes floodplain elevation. The building itself is only part of the figure. Give us the parcel in the survey and we will price that ground. The barndominium cost guide has sourced ranges and the main cost drivers.

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

Yes. The county's Building Safety Department reviews the plans under its 2018-based codes and inspects the work, and a rural lot usually also needs a septic permit and, in a floodplain, a Floodplain Use Permit. On turnkey builds we prepare the drawings and file the applications; kit buyers file with our drawings. See our permitting service.

Do pole barn homes suit rural Pinal County land?

Often, yes. Pole barn homes put the posts in the ground under a clear-span roof, which leaves room for equipment or horses under the same roofline. A steel barndominium on a slab is the other common choice out here. Our pole-barn page and site preparation page explain what each needs from the ground.

Which parts of Pinal County do you cover?

The unincorporated county plus the towns and cities within it, including San Tan Valley, Casa Grande and the City of Maricopa. Each has a different permit office, so we confirm the jurisdiction from the parcel record before we draw.
