Certificate of Occupancy / Change of Occupancy Permit in Casa Grande, Arizona

Required whenever a building in Casa Grande is occupied for the first time, or when there is a change of tenancy, ownership, or use of an existing building or tenant space. Governed by Casa Grande Code of Ordinances Title 15, Article IV (Issuance of Building Permits and Certificates of Occupancy). Any new business location, change of ownership, or change of use requires an occupancy inspection conducted jointly by the Building Department and the Fire Department before occupancy is authorized. Casa Grande runs two distinct tracks: a construction-involved 'Change of Occupancy / Major Alteration / T.I.' commercial building permit, and a no-construction 'Change of Occupancy Permit' (billed as the flat-fee Occupancy Permit) for a simple tenant, ownership, or use change to an already-code-compliant space.

When you need this permit

  • A Certificate of Occupancy (or Occupancy Permit) is required for each new occupancy of a building; a change of tenancy, ownership, or use of an existing building may also require a new Certificate of Occupancy or Occupancy Permit to be issued
  • Any new business location, change of ownership, or change of use requires an occupancy inspection conducted by BOTH the Building Department and the Fire Department, per the City's own 'Determining if Your New Business Location Meets Planning & Building Requirements' guidance
  • A change of occupancy/use accompanied by construction, tenant-improvement work, or an occupancy-classification change is processed as the Commercial/Industrial 'Change of Occupancy / Major Alteration / T.I.' building permit, using the standard Building Permit Application and the valuation-based Building Permit Fee table documented in the residential-building-permit and electrical-permit entries
  • A change of occupancy/use with no construction work (simple tenant, ownership, or use change verifying the existing building still meets code) is processed under the Miscellaneous 'Change of Occupancy Permit' track at the flat Occupancy Permit fee
  • Confirm the proposed use is allowed in the applicable zoning district BEFORE signing a lease or applying -- email the Planning Department or request a Zoning Verification Letter
  • A City business license is required to conduct business at the permitted location
  • A Certificate of Occupancy issued together with a new building permit carries no separate charge; Temporary and Partial Certificates of Occupancy are billed as standalone line items

Tips

  • Any new business location, change of ownership, or change of use in Casa Grande requires an occupancy inspection conducted by BOTH the Building Department and the Fire Department -- budget time for two inspections, not one.
  • If no construction is involved, a change of occupancy is billed at the flat $100.00 Occupancy Permit fee under the 'Change of Occupancy Permit' Miscellaneous track (24-business-day maximum); if the change of use involves construction or tenant-improvement work, it is processed as a full Commercial 'Change of Occupancy / Major Alteration / T.I.' building permit at the valuation-based Building Permit Fee table (44-business-day maximum) documented in the residential-building-permit entry.
  • Confirm your proposed use is allowed in the zoning district BEFORE signing a lease -- email the Planning Department or request a Zoning Verification Letter ($50.00) to avoid discovering only at permit application that a use isn't allowed on the property.
  • A Certificate of Occupancy issued together with a new building permit carries no separate charge; only Temporary ($200.00) and Partial ($200.00) Certificates of Occupancy are billed as standalone line items.
