Tips

  • Plumbing single-trade permits fall under 'Single Trade (MPE Permit)' on the City's A.R.S. § 9-835 review timeframe chart: 2-business-day Administrative Completeness Review, plus 10 business days each for Initial and Resubmittal Substantive Review (24-business-day Over-All Timeframe maximum).
  • Gas line repair is not a routine same-day item — the utility company will not restore gas service until the City has inspected and approved the repaired line, so plan for the permit/inspection cycle before requesting reconnection.
  • Electrical, mechanical, and plumbing single-trade permits share one consolidated flat fee line ($75 residential / $300 commercial) on the fee schedule rather than separate per-trade dollar amounts.
