Do I need a permit for swimming pool or spa in Guilford County?

Yes. In North Carolina, swimming pool or spa generally requires a permit, and Guilford County is no exception.

A permanent in-ground or above-ground pool requires building and electrical permits because it involves structural and electrical work; it is never covered by the minor-work exemption. NC Residential Code requires a compliant barrier (fencing, gate self-closing/self-latching, and alarms as applicable) before the pool is approved for use. Guilford County's own permitting office is the Guilford County Inspections Department, reachable on 336-641-3707 at https://www.guilfordcountync.gov/government/departments-and-agencies/inspections. Its online permit portal is https://citizenaccess.guilfordcountync.gov/energov_prod/selfservice#/home. It issues permits for the unincorporated county. If your city does not run its own building department, this is the office that will handle the job, and that is more common in North Carolina than most states: the county is often the building authority even inside city limits, with the city handling only zoning. A pool involves a building permit, a separate electrical permit for bonding, and a barrier inspection before final sign-off. Guilford County applies NC Residential Code Appendix V to pools, hot tubs, and spas holding water more than 24 inches deep. The residential pool permit fee is $150 including electrical, or $255 for a heated pool including electrical and fuel. A deck supporting a hot tub or spa needs a letter or stamped plans from an engineer verifying the deck can carry it. Guilford County Inspections permits and inspects all unincorporated addresses, and by contract also Jamestown, Oak Ridge, Pleasant Garden, Sedalia, Stokesdale, Summerfield, Whitsett, and the Piedmont Triad Airport Authority. Jamestown, Oak Ridge, Sedalia, Summerfield, Whitsett, and PTAA addresses need a town Development Clearance Certificate before applying.
