Kirkland FAQ
Do I need a fence around my hot tub?
Not if you install a lockable cover meeting ASTM F1346; without such a cover the hot tub must be inside a 48-inch pool-style barrier with self-closing gate.
Can I put my hot tub on my existing deck?
Yes if the deck is engineered to support the filled spa load and a licensed contractor installs an appropriate electrical feed; a structural review during permitting confirms adequate support.
Renton FAQ
Do I need a fence around my Renton hot tub?
Not if you use a locking ASTM F1346 safety cover. Without the cover, a 48-inch IRC Appendix G barrier is required around the spa.
Can I plug my hot tub into a regular outlet?
No. A dedicated 240V circuit with GFCI protection per NEC Article 680 and a bonding grid is required; an electrical permit is mandatory.
