Applies to: Certificate of Occupancy (Change of Use/Occupancy)

  1. 1

    Building Final Inspection (new construction)

    For new construction, the CO is issued upon the Building Final Inspection already documented as the final step of this file's residential-building-permit entry (order 6) — no separate CO-specific inspection exists in that scenario.

  2. 2

    As-Built / Occupancy Classification Verification (change of use on existing building)

    For a change of use on an existing building with no new construction, no distinct published inspection checklist was found; a site visit by the Building Official to confirm the building meets the applicable code requirements for the new occupancy classification is standard IBC § 111 practice, but Doña Ana County does not itemize this on any published document — confirm the process with Building Services, (575) 647-7350.

Applies to: Electrical Permit

  1. 1

    Electrical Rough-In

    Panel, all wire boxes for receptacles, switches, cable, phone, and lighting — part of the 2nd-phase inspections on new construction

    Fire Prevention Plan Review

    Construction documents for automatic fire-extinguishing and fire alarm systems are reviewed by the County Fire Code Official (Fire Prevention Division) prior to permit issuance, per the adopted IFC's administrative provisions and DAC Code § 195-3(A)(8).

  2. 2

    Final Fire Inspection

    A final inspection by the Fire Prevention Division confirming the installed system matches the approved plans is required before the system may be placed in service, consistent with the adopted IFC's general permit/inspection framework. Doña Ana County does not publish a distinct itemized inspection checklist for fire-sprinkler/alarm permits specifically (unlike the phased building/electrical/plumbing inspection checklists documented elsewhere in this file) — confirm the specific inspection sequence with the Fire Prevention Division, (575) 647-7925.
