Federal Way FAQ
Does my Federal Way hot tub need a fence?
Only if it lacks a lockable safety cover meeting ASTM F1346. Hot tubs with compliant covers are typically exempt from perimeter barrier requirements.
Do I need permits for a hot tub?
Yes. Hot tubs deeper than 24 inches require a building permit plus an electrical permit for the dedicated GFCI circuit and any plumbing work.
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.
