Arizona's desert climate creates unique code requirements — cool roofing, thermal mass, and energy efficiency standards are more demanding than most states. Phoenix and Tucson have invested heavily in online permitting and express permit programs for common project types.

How to get a building permit in Arizona
1
Find your city or county portal
Arizona's 15 counties and major cities each have their own systems. Phoenix, Scottsdale, Tempe, Mesa, Chandler, and Tucson all offer robust online permitting.
2
Check for express permit programs
Phoenix, Scottsdale, and several Valley cities offer express permits for common projects (HVAC, water heater, re-roof) with same-day or next-day approval.

Submit plans if required
Trade permits usually do not require plans. Structural projects require architectural plans. Arizona-specific: energy compliance (ResCheck or COMcheck) and pool barrier compliance plans.

Pay fees
Arizona permit fees are moderate nationally. Phoenix charges roughly 1% of project valuation for construction permits. Most trade permits are flat-rate.
5
Inspections
Major Arizona cities offer online inspection scheduling with next-day availability. Final inspection is required before occupancy for all structural work.

Frequently asked questions — Arizona permits
Does Arizona have a statewide building code?
Arizona does not mandate a single statewide code, but most cities and counties have adopted the IBC/IRC. Maricopa County enforces codes in unincorporated areas. Some rural areas have minimal requirements.
How ADU-friendly is Arizona?
Very. Arizona passed statewide ADU preemption legislation that prevents cities from imposing unreasonable restrictions. Cities cannot require owner-occupancy, prohibit rental, or set parking requirements that make ADUs impractical.
What is the Arizona Solar Rights Act?
Arizona law prohibits HOAs and local governments from unreasonably restricting solar panel installation. Solar permits are streamlined and approvals are generally fast — often under a week.
How do pool permits work in Maricopa County?
Pool permits require plan review showing pool location, barrier design, and equipment placement. Multiple inspections are required: steel, shell, fence, electrical, and final. Water cannot be added before final inspection passes.
