Tucson enforces strict zero-tolerance permitting for accessory structures. Our steel garages meet all local setback and UDC codes.
Building in Tucson, Arizona
Tucson properties often require practical, durable storage solutions for vehicles, equipment, and everyday use. Between local weather patterns and specific property layouts in Pima County, a pre-engineered steel garage provides the secure, enclosed space that residents need without the long timelines of traditional construction.
Our custom metal garages installed in Tucson are designed to handle the specific environmental demands of the Sonoran Desert region. Whether you need a compact single-car structure for a tight residential lot or a massive clear-span workshop for agricultural or commercial use, every building can be customized. Owners can adjust width, length, height, roof style, and color options to perfectly match their property before installation begins.
Popular Use Cases
- Compliant rear-yard steel garages and workshops
- Engineered RV covers and metal carports

Climate & Geography
Tucson soils often contain hardened caliche layers causing perched water tables and uneven bearing capacities. Proper site preparation and engineered concrete footings are critical to prevent differential settlement.

Possible Exemptions
The report groups Tucson/Pima with major Arizona jurisdictions using model accessory-structure exemptions around detached, single-story, non-habitable buildings up to 200 square feet, 10 feet high or less, and without electrical, plumbing, or mechanical systems. Local Tucson rules should be verified before relying on the exemption.
Setbacks
Accessory structures are generally subordinate to the primary dwelling and prohibited in required front yards or forward of the primary dwelling's front plane. Local Pima County or Tucson zoning determines parcel-specific side/rear setbacks.
Foundation
The report lists Pima County/Tucson at 115 mph Vult, SDC B or C, 0 psf snow load, 0 inch frost depth, and 1,500 psf prescriptive soil bearing. Expansive soils and caliche can require engineered foundations.
Inspections
Utility connections void the basic no-utility exemption and trigger trade permit review. Local Tucson/Pima submittal and inspection portals should be verified for the parcel jurisdiction.
