Regulations
Building a Prefab Home in Arizona: What You Need to Know
Before you start building a prefab home in Arizona, it’s critical to understand the state’s building codes, zoning laws, and permit requirements. Every county and municipality in Arizona sets its own rules for lot size, septic and well systems, energy compliance, and inspections. These rules determine whether your project qualifies as a primary residence, vacation cabin, or rental property. To help you plan successfully, here are the most important regulations to watch—plus reliable resources with detailed guidance on Arizona housing codes and local zoning.
Key Regulation Areas & Resources
Zoning & Permits: Arizona requires building permits at the county or city level. Permits typically cover site plans, septic approval, and compliance with the Arizona State Building Codes. Modular and factory-built buildings are regulated by the Arizona Office of Manufactured Housing (OMH), part of the Department of Housing.

Tiny & Cabin Size Limits: Arizona has no statewide law for tiny homes. Many counties adopt the International Residential Code (IRC), which sets minimum ceiling heights, egress windows, and utility standards. Cities like Phoenix and Tucson are exploring accessory dwelling unit (ADU) ordinances.

Off-Grid & Rural Builds: In rural Arizona, prefab homes on acreage often require septic permits from county health departments. Septic and well approvals are handled locally under rules from the Arizona Department of Environmental Quality (ADEQ).

Energy Code & Weatherization: Arizona follows the 2018 International Energy Conservation Code (IECC) with local amendments in many jurisdictions. Requirements cover insulation, HVAC efficiency, and energy performance standards critical for desert climates.
