Change of Use / Change of Occupancy Permit in Unincorporated Navajo County, Arizona

Navajo County expressly requires a permit to change the occupancy of a building or structure in the unincorporated county, and the Building Official must issue a Certificate of Occupancy before any change in the existing occupancy classification takes effect. The county publishes no distinct change-of-occupancy fee line; the work is priced as a Building Permit on the IBC/UBC Building Valuation Data and IRC 2018 charts adopted by Board of Supervisors Resolution 9-2022, plus Plan Review/Check at 35% of the total building permit fee. Fire and life-safety review for the new occupancy is performed by the fire district serving the parcel, not by Navajo County, which adopts no fire code.

Inspection process

  1. 1

    Required inspections per the Addenda & Additions

    The county's published inspection list (Addenda & Additions, 'Required Inspections', printed page 8) covers septic systems, foundation piers/trenches, rough plumbing/mechanical/gas/electrical prior to covering, floodplain, fire resistance where required, footing steel, stem steel, under-slab, under-floor framing, roof sheathing and shear panel nail-off, rough-in framing/electrical/plumbing/venting/heating, drywall nailing and final; which of these apply depends on the scope of the occupancy change. Additional inspections may be required for specialized projects.

  2. 2

    Final — Certificate of Occupancy

    'All inspections must be performed, and work approved before issuance of a Certificate of Occupancy' (Addenda & Additions, printed page 8). No change in the existing occupancy classification is effective until the Building Official has issued the Certificate of Occupancy (printed page 6).

Tips

  • Navajo County does not review fire and life safety for your new occupancy — it adopts no fire code. The fire district serving your parcel (for example Timber Mesa Fire and Medical District or Pinetop Fire District) runs its own plan review, issues its own construction permit and bills you directly. Start that conversation before you submit to the county.
  • There is no published change-of-occupancy fee. The county prices the work as a building permit on the adopted valuation charts plus 35% plan review, so a change of use with little or no construction value has no published price — call Planning & Development Services at 928-532-6040 for a project-specific quote.
  • Planning & Development Services works Monday through Thursday only. Emergency inspections are offered Fridays at $75.00 per hour with a Thursday 3:00 p.m. scheduling cutoff.
  • An approved septic system or a Letter of Release from a Sanitary District is a hard prerequisite to permit issuance — if the new occupancy increases fixture load, resolve wastewater capacity first.

The fire district serving the parcel, not the county. Navajo County adopts no fire code and its fee schedule carries no fire line. Timber Mesa Fire and Medical District states that it conducts plan reviews and requires permits on construction projects and occupancy operations, works in conjunction with the Navajo County Building and Planning Department, and that fees for a district permit must be submitted directly to its own office as a separate process from the jurisdictions it serves. Pinetop Fire District issues construction permits based on the International Fire Code and publishes its own fire sprinkler permit form.
