What is a certificate of occupancy?

A certificate of occupancy (CO) is the formal document a city or county issues to confirm that a building or individual unit has passed all required inspections and meets local building codes, fire codes, and safety standards. In Greater Austin, the municipality will not permit tenants to legally move into a new apartment complex or lease-up unit until this certificate is in place.

For apartment developers and operators, the CO is a mandatory legal gateway between construction completion and revenue generation. Austin's building and planning departments conduct final inspections covering structural integrity, electrical systems, plumbing, fire suppression, egress routes, and accessibility compliance. Only after all deficiencies are corrected and signed off will the city issue the certificate.

The CO matters because it protects both residents and property owners. Residents gain assurance the unit is habitable and safe. Operators avoid liability and legal penalties for leasing uninspected or non-compliant space. Lenders and investors also require COs before funding or appraising new lease-ups, making it essential to project timelines and lease-start dates.

In Austin's competitive apartment market, timing of the CO directly affects when a building can begin collecting rent. Delays in the inspection process or code corrections can push lease-up windows and cash flow projections. Once issued, a CO remains valid unless the building undergoes major renovation or change of use.
