Who issues permits in Pinal County?
Depends on your address
Inside city limits, the city building department issues the permit. Outside city limits — unincorporated Pinal County — the county building department reviews, permits and inspects the work. Both enforce the same code basis (Local adoption of the IRC by city and county), but fee schedules, zoning setbacks and review times differ.

Common questions
Who issues my permit — the city or the county?
If your address is inside city limits, the city building department issues the permit. Outside city limits, the county building department does. A quick call to either office with your parcel number settles it in a minute.
Can I pull my own permit as a homeowner?
Most states allow an owner-builder permit on a home you occupy, with conditions: you may have to appear in person, sign an affidavit, and you cannot hire unlicensed help. Trades like electrical and gas often still require a licensed contractor.
What happens if work was done without a permit?
Unpermitted work usually surfaces at resale or during an insurance claim. Most jurisdictions offer a retroactive or after-the-fact permit, typically at a higher fee, and may require opening finished areas so an inspector can see the structure.
How long does permit review take?
Simple over-the-counter trade permits are often same-day to a week. Structural or additions work commonly runs two to eight weeks depending on backlog, and coastal, historic or floodplain review adds time.
