Tips
- Over-the-Counter electrical permits carry a $29.90 base fee plus itemized per-item charges (e.g., $38.85 for a sub-200-amp service entrance).
- Service entrances or subpanels rated above 400 amps cannot use the Over-the-Counter process — they require a full Building Permit application with an electrical plan, load calculation, and panel schedules.
- Aluminum wire may only be used for feeders and service-entrance conductors under Flagstaff's NEC amendment — never for branch-circuit wiring.
- reviewTimelineDays is 0 (no plan-review period): a qualifying Over-the-Counter electrical permit is issued at the counter with no two-stage plan review. The City's ARS 9-835/9-836 timeframes documents (Residential Building Permits Plan Review Process and Timeframes; Commercial Plan Review) and the Over-the-Counter Permit Application itself contain no plan-review timeframe for OTC trade permits because they are not plan-reviewed. Only if the work exceeds OTC limits (e.g., a service/subpanel over 400 amps) does it convert to a full Building Permit reviewed under the 'Small Residential Plans' track (35 working days overall).
