Occupancy Permit

The occupancy permit (also called certificate of occupancy or CO) marks official project completion. Issued after all final inspections pass, it certifies the building meets code requirements and is safe for use. New homes can't be occupied without a CO. Major remodels affecting occupancy may require a CO before use. The permit documents legal occupancy—required for: moving in, getting utilities connected, obtaining insurance, and selling the property. Without a CO, the building legally cannot be occupied.

How to Obtain It

After construction completion, schedule final inspections with San Diego Development Services. Inspectors verify: all work matches approved plans, required inspections were completed and passed, all code corrections were made, and smoke detectors and carbon monoxide detectors are installed. Once final inspection passes, the department issues the occupancy permit. Keep this document with permanent property records—you'll need it for insurance, refinancing, and selling. For major remodels, clarify early whether an occupancy permit will be required.
