Phoenix can issue a temporary certificate of occupancy before the entire permitted project is complete, provided the approved portion can be occupied safely. It requires the city’s process, applicable inspection approvals, written conditions and a valid stated term. Unfinished plumbing is not automatically acceptable, and a contractor’s readiness statement cannot substitute for the signed occupancy authorization.
What should the owner identify first?
A Phoenix temporary certificate of occupancy can cover an approved portion before all work under the original permit is finished. That does not mean an owner can open around any unfinished plumbing. The city must determine that the proposed portion can be occupied safely, and its stated scope and conditions govern the use.
Phoenix's adopted administrative provisions address temporary occupancy in Section 111.3. The city's published TCO permit process adds the practical inspection and signing steps. This page concerns Phoenix; another jurisdiction's temporary-occupancy process may differ.
Describe the exact portion and use requested:
- Rooms or levels proposed for occupancy and any areas remaining construction space.
- Working restrooms, handwashing and other plumbing needed for that use.
- Affected supply, drainage, equipment and dependent systems.
- Routes into, through and out of the occupied portion.
- Work still open, how it is separated and when it is planned for completion.
An unfinished fixture outside the requested portion is a different issue from an essential sink inside it. Have the designer and city inspectors evaluate the actual layout rather than assuming the same answer applies to both.
Which approvals make the TCO valid?
The city's process calls for pre-TCO approval by all applicable disciplines under the original building permit. The owner or agent then works with an Inspections Field Supervisor on the TCO permit, conditions and required inspections. The city document says it becomes valid only after all inspection disciplines and the owner or agent have signed it.
Accessibility and applicable fire and life-safety systems also have completion requirements in the TCO process. Plumbing approval alone does not complete those disciplines. Plumbing final versus occupancy approval explains that separation. A failed inspection still needs its required correction or accepted resolution.
Can stocking begin before customer occupancy?
Phoenix's process distinguishes a stocking-only TCO from full occupancy and says stock-and-train TCOs are considered full occupancy. Get the approved use stated on the permit. Do not expand it based on a verbal understanding or a planned opening date.
The city sets the term, which cannot exceed the duration of the original permit. Scope changes require the city's applicable TCO process. Track the signed conditions and expiry alongside the open-permit file.
Food establishments also need the applicable Maricopa County operating approval. A city TCO does not replace that separate process. Keep both approvals with the closeout documents, and resolve operating questions before occupants begin the use.
