Change of Use (No Distinct Certificate-of-Occupancy Process — Routed Through the Zoning Use Permit's Amendment Track) in Duncan, Arizona

The Town of Duncan does not issue a Certificate of Occupancy and has no standalone 'change of use permit.' Town Code Chapter 7 (Building) contains no occupancy-certificate or final-occupancy-sign-off provision of any kind, and no such document appears on the Town's Building Permits & Fees page, the Application for Building Permit and Inspection form, or the combined Zoning Use, Building, Historic District and Floodplain Permit form. Instead, a change in use is handled as the 'Amendment (changed use)' line already present on that combined permit form — the same Board of Adjustment hearing track documented in this file's zoning-use-permit entry — and, in at least the Public Zone (Town Code § 15-7-3(D)-(E), Rev. 03/20), an explicit 'change of use variance' can trigger added off-street parking and loading-space requirements once a specific use classification changes.

When you need this permit

  • No Certificate of Occupancy is issued by the Town of Duncan for any use — confirmed absent from Town Code Chapter 7 (Building, Rev. 6/06), the Building Permits & Fees page, the Application for Building Permit and Inspection form, and the combined Zoning Use/Building/Historic District/Floodplain Permit form
  • A change of use is processed via the 'Amendment (changed use)' line on the combined Zoning Use, Building, Historic District and Floodplain Permit form, which routes to a Board of Adjustment hearing (per Town Council, per the form's own labeling) — the identical track documented in this file's zoning-use-permit entry
  • In the Public Zone specifically, a 'change of use variance' after the code's effective date triggers off-street parking at 3 spaces per 1,000 sq ft of floor space (1 space per 5 seats for churches) and, for buildings of 2,000 sq ft or more receiving/distributing merchandise by vehicle, at least one off-street loading space of 10' x 25' x 14' (Town Code § 15-7-3(D)-(E))
  • As with any Zoning Use Permit action, the resulting permit becomes void six months after issuance unless substantial utilization has begun, and must be posted on-site during construction

    Tips

    • Duncan issues no Certificate of Occupancy of any kind — do not expect a final 'C.O.' document at project completion the way many larger Arizona cities provide one. A change in use is instead an 'Amendment (changed use)' action on the same combined permit form used for the Town's Zoning Use Permit, billed at the same $200 Amendment Application fee.
    • If your change of use falls within the Public Zone specifically, watch for the added off-street parking (3 spaces/1,000 sq ft) and loading-space (10'x25'x14' for 2,000+ sq ft buildings receiving merchandise by vehicle) triggers under Town Code § 15-7-3(D)-(E) — these are the only explicit 'change of use variance' consequences named anywhere in Duncan's zoning code.
    • Because this action shares the Zoning Use Permit's Board of Adjustment hearing track, it also shares that track's unpublished review-timeline gap — budget lead time for a hearing cycle and confirm current Board of Adjustment meeting dates with Town Hall directly.

Title 9 for municipalities). The Town of Duncan is a small incorporated town that runs its own building-permit program directly out of Town Hall (the Town Manager's office functions as Building Official) rather than deferring to Greenlee County; this is confirmed by the Town's own Building Permits & Fees page, its Chapter 7 (Building) town code chapter, its Schedule of Fees and Charges, and its paper 'Application for Building Permit and Inspection' form, all of which are Duncan's own documents (not county documents).
