Arizona permits
Do you need a permit in Arizona?
Arizona enforces the IRC with state amendments at the municipal or county level. The Arizona Registrar of Contractors (AZ ROC) requires licensed contractors for any single residential project over $1,000 (including labor + materials), which is one of the stricter thresholds in the country. Major metros (Phoenix, Tucson, Mesa, Scottsdale) have full building departments; smaller jurisdictions vary.

Can a homeowner pull the permit?
Yes, in most cases. Owner-builder exemption applies to primary residences only. Homeowner self-performing is exempt from AZ ROC licensing. Hiring covered work requires a licensed contractor.
Where to file: City building department for incorporated areas, county for unincorporated. Phoenix uses PDD online; Maricopa County has online permitting. Plan review is typically 1-3 weeks.
