Cary FAQ
Can my hot tub cover replace a fence?
Yes — a locking safety cover meeting ASTM F 1346 satisfies the barrier requirement under NC Residential Code Appendix V.
Does my deck need an engineer's letter?
Yes for any new or modified deck supporting a hot tub. The letter must verify the deck supports the filled tub plus occupants.
Can I plug it into an outlet?
Generally no — most spas require a dedicated 240V GFCI circuit installed under permit. Plug-in 110V models still require GFCI compliance.
Raleigh FAQ
Do I need a fence around my hot tub in Raleigh?
Not if you install an ASTM F1346 lockable safety cover and keep it locked when not in use. Otherwise, a 48-inch barrier with self-latching gate is required.
Can I install a hot tub myself without a permit?
No. Raleigh requires an electrical permit even for plug-and-play 110V units when hardwired, and a 240V installation must be done by a licensed NC electrician with inspection.
