Tips

Custom single-family homes: 12/8 working-day review goals (1st/2nd reviews); standardized plans: 3/3 days. Targets are A.R.S. § 9-835 max time frames.
All permit applications go through OneStopShop at onestopshop.gilbertaz.gov — not a walk-in counter process.
Permits expire if substantial work is not started and inspections are not requested within 180 days of issuance. One 180-day extension may be requested in writing.
Work-before-permit-issuance doubles the permit fee (penalty equals the full permit fee per Gilbert's IBC §109.4 amendment).
Up to 80% of permit and plan review fees are refundable if no work is done or application is withdrawn; written request required from original permittee.
Soils reports: call (480) 503-6700 before assuming you need a new one — your subdivision may already have one on file.
