Hot tubs and spas in Apex are treated as pools under NC Residential Code Appendix V (2018) / Appendix NC-A (2024) and require Wake County building and electrical permits when they hold more than 24 inches of water. Spas and hot tubs with a safety cover that complies with ASTM F1346 are exempt from the barrier provisions of Appendix V (AV105.5). Decks supporting a hot tub or spa require engineer-stamped plans verifying load capacity (Wake County). Apex UDO Sec. 8.2.7.A.4.b requires any chain link around a residential hot tub or spa to be vinyl coated in black, brown, or dark green.
Appendix V Section AV105.5 (Indoor swimming pool / spa exception): 'Spas or hot tubs with a safety cover that complies with ASTM F1346 shall be exempt from the provisions of this appendix.' This is the critical distinction from in-ground pools: a hot tub with a listed ASTM F1346 safety cover does not require a 48-inch perimeter barrier. Wake County confirms: 'All swimming pools, hot tubs, and spas that hold more than 24 inches of water need both a building and an electrical permit,' so the permit obligation still applies even for hot tubs without a separate barrier. Wake County also states that 'Decks supporting hot tubs/spas need engineer-stamped plans verifying load capacity' (commonly 100 pounds per square foot for spa decks under the NC Building Code). Pool/spa electrical bonding must comply with NEC Article 680, enforced by Apex Building Inspections at (919) 249-3418. Apex UDO Sec. 8.2.7.A.4.b expressly lists 'hot tubs, spas' alongside other recreational accessory uses subject to the vinyl-coated chain link requirement when chain link is used around them. Sec. 4.5.4 of the UDO governs accessory uses such as residential spas.
Installing a hot tub or spa holding more than 24 inches of water without Wake County building and electrical permits is a code violation. A hot tub on a deck without engineered load verification violates Wake County's site plan requirements. A hot tub without an ASTM F1346 cover or a code-compliant 48-inch barrier violates Appendix V. Uncoated chain link around a residential hot tub violates Apex UDO Sec. 8.2.7.A.4.b.
