Guilford County, NC Building Safety: Building Inspections (2026)

Guilford County's Unified Development Ordinance makes the Certificate of Occupancy (CO) the final checkpoint of the building process. An application for a CO must be filed concurrently with the building, sign, use, or location permit application, and the county will not issue it until every permit condition is satisfied. Before signing off, the Planning and Development Director or other authorized county staff must inspect the completed work to confirm it complies with all applicable provisions of the Unified Development Ordinance. Where a septic system, well, or other on-site sanitary disposal method serves the property, the applicant must also produce a septic system Operations Permit or a well Certificate of Completion issued by the County or State Health Department before occupancy is authorized, and the project must separately comply with the applicable health, building, and fire codes.

If work is finished except for minor remaining items, the Director can issue a Temporary Certificate of Occupancy allowing use to begin early, provided the gap poses no health or safety risk; that temporary certificate runs for up to 180 days and the county may require a surety bond guaranteeing the missing elements get completed. A new Certificate of Occupancy is also required whenever a nonconforming use is renewed or altered. S. S. 143-138, other than residences, are exempt from these certificate requirements, though electrical systems in those buildings must still meet the NC Electrical Code even when the structure itself is exempt.
