Auburn FAQ

Does my hot tub need a fence?

Not if you have an ASTM F1346 compliant safety cover that locks. Otherwise the same IRC Appendix G barrier rules as pools apply.

Can I plug my hot tub into a regular outlet?

Only 120V plug-and-play models on a dedicated GFCI circuit. 240V hardwired units need a licensed electrician and permit.

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.
