This is PermitBase’s published record for Flagstaff as of 2026-07-20. It has since been superseded — see the current record. A historical record reflects what PermitBase had verified at that time; it may not capture a real-world change the jurisdiction had made but PermitBase had not yet verified, and it includes any errors we later corrected.

Codes adopted
Arizona has no mandatory statewide building code edition — cities and counties each adopt and amend their own codes (per Arizona Revised Statutes framework for municipal building regulation; no state building-code-adoption agency parallel to Montana's DLI exists). The City of Flagstaff independently administers its own Building Safety program within city limits, separate from Coconino County's building department, which handles unincorporated county areas.

EV Charger / Electric Vehicle Charging Circuit Permit
VerifiedFlagstaff has no standalone EV charger permit or fee line — installing an EV charger circuit is electrical work processed through the same Over-the-Counter (OTC) or full Electrical Permit pathway documented in the electrical-permit entry, billed under the generic 'Circuits (each)' or service/subpanel line items (no work item is itemized specifically as 'EV charger' on the OTC fee schedule). Separately, Flagstaff's 2019 local amendment to the 2018 IRC (Chapter 4-03) REQUIRES new one- and two-family dwelling construction to include at least one dedicated 208/240-volt, 50-amp-minimum garage branch circuit for EV charging (2018 IRC E3901.9 as amended) — this requirement is verified directly in codesAdopted/residential-building-permit, but it is a new-construction code mandate, not a separate retrofit permit type. Re-chased 2026-07-20: directly downloaded and text-extracted the live OTC Permit Application PDF, confirming the exact same fee figures verbatim ($29.90 base, $6.05/circuit, $38.85/$79.15 subpanel tiers) are still current.

- Retrofitting an EV charger circuit into an existing home: apply for an Over-the-Counter (OTC) electrical permit for the circuit (and, if needed, a service entrance or subpanel upgrade) — no EV-specific line item exists, so the applicable OTC category is 'Circuits (each)' plus any panel/service upgrade required to support the load
- Governed by the 2017 NEC as adopted and locally amended by the City of Flagstaff (copper-only current-carrying conductors; aluminum only for feeders/service-entrance conductors)
- If the service entrance or subpanel must be upgraded above 400 amps to support the charger, a full residential or commercial Building Permit application (site plan, load calculation, panel schedule) is required instead of the OTC pathway
