Do I need a permit for swimming pool or spa in Cary?
Yes. In North Carolina, swimming pool or spa generally requires a permit, and Cary 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. The Town of Cary requires a permit to install a swimming pool, hot tub, or spa, including above-ground pools, that contains 18 inches or more of water, so above-ground pools are not automatically exempt here. Installing or replacing the pool barrier fence also requires a permit, and the barrier must be in place before the work passes final inspection. Review the Town's Residential Swimming Pools, Spas, and Hot Tubs Guide and confirm setbacks with a plot plan and as-built survey, since a pool near a setback, easement, or buffer needs an as-built survey. Wake County's own permitting office is Wake County Permits and Inspections. It issues permits for the unincorporated county, and in North Carolina the county is often the building authority even inside city limits, so confirm which applies to your address. Erosion control here depends on which town you are in. Wake County administers erosion control for all unincorporated areas plus six municipalities under interlocal agreements: Garner, Knightdale, Morrisville, Wendell, Rolesville and Zebulon. If you are in one of those six, or in the unincorporated county, your plan goes to Wake County. Raleigh, Cary, Apex and the other Wake towns run their own programs. A pool means excavation and spoil handling, so on a large lot this is the residential project most likely to approach the one-acre disturbance threshold. The trigger is size, not cost: Wake County reviews construction plans for land development over one acre of disturbance. Ordinary single-family work is normally well under that, so this bites on large lots, big site regrading, or a project combined with substantial clearing.
