Certificate of Occupancy / Change of Occupancy in Gilbert, Arizona

The Town of Gilbert does not offer a standalone 'change of use' or 'change of occupancy' application distinct from its Building Permit process. A standard Certificate of Occupancy is issued automatically upon passing final inspection under an active, paid Building Permit (per IBC §111 as adopted). For situations without new construction, Gilbert's adopted fee schedule separately lists a 'Courtesy Certificate of Occupancy (C of O)' product (two price tiers, Option A and Option B) and a 'Temporary Certificate of Occupancy (TCO) or Partial Certificate of Completion (PCC)' product used to grant occupancy of part of a building before the entire project is complete. Critically, Gilbert's local Fire Code amendment (2018 IFC §903.2.2, Town of Gilbert Technical Codes 2020 Edition) requires an automatic fire sprinkler system to be installed whenever a building within Fire Hazard Level 1 undergoes a change of occupancy, regardless of building area — this is the primary code trigger tied to a change of occupancy in Gilbert.

When you need this permit

  • Submit through OneStopShop portal at onestopshop.gilbertaz.gov if a permit is required for the change of occupancy (e.g., fire sprinkler retrofit or other construction)
  • A building must pass final inspection under an active, paid Building Permit before legal occupancy, per IBC §111 as adopted by the Town of Gilbert
  • A change of occupancy within Fire Hazard Level 1 requires installation of an automatic fire sprinkler system regardless of building area, per 2018 IFC §903.2.2 as locally amended (Town of Gilbert Technical Codes 2020 Edition)
  • A Temporary Certificate of Occupancy (TCO) is capped at 60 calendar days per issuance; renewals (also capped at 60 additional days each) are granted at the sole discretion of the Building Official based on remaining work; if the TCO and any extensions expire without completion of all outstanding items, the matter is referred to Code Compliance for enforcement (IBC §111.3 as locally amended)
  • Contact Development Services at (480) 503-6700 to confirm which Courtesy Certificate of Occupancy fee tier (Option A or Option B) applies — the published fee schedule does not itself define the criteria distinguishing the two tiers

Inspection process

  1. 1

    Final Inspection (Standard Certificate of Occupancy)

  2. 2

    Fire Sprinkler System Inspection (Change of Occupancy, Fire Hazard Level 1 only)

    Required when a change of occupancy within Fire Hazard Level 1 triggers the automatic fire sprinkler system requirement under 2018 IFC §903.2.2 as locally amended, regardless of building area

Tips

  • Gilbert has no dedicated 'change of use permit' or 'change of occupancy permit' application in OneStopShop — a change of occupancy is handled either as a Courtesy Certificate of Occupancy request (no construction) or through the standard Building Permit / Tenant Improvement process (if construction is involved).
  • The fee schedule lists two Courtesy Certificate of Occupancy price tiers ($110 Option A / $250 Option B) but does not publish the criteria distinguishing them — call Development Services at (480) 503-6700 before assuming which applies.
  • A change of occupancy within Fire Hazard Level 1 triggers a mandatory automatic fire sprinkler system retrofit regardless of building size, per Gilbert's local IFC §903.2.2 amendment — a significant, easy-to-miss requirement for anyone occupying an existing building under a new use classification without other construction work.
  • A Temporary Certificate of Occupancy (TCO) or Partial Certificate of Completion (PCC) is capped at 60 calendar days and may be renewed at the Building Official's discretion (also capped at 60 additional days per renewal); renewal fees escalate ($125 / $250 / $500 for 1st / 2nd / 3rd renewal).
  • The $340 TCO/PCC exception rate applies specifically to an initial TCO or PCC for a tenant improvement under 2,000 sq ft that requires only Building, Fire, and Backflow signatures.
