Renton FAQ
Does a hot tub need a pool barrier in Renton?
A hot tub with a lockable, code-compliant safety cover meeting ASTM F1346 standards can satisfy the barrier requirement in place of a full fence.
Can my house wall be part of the pool barrier?
Yes, but all doors and windows opening into the pool area must have alarms, lockable window guards, or other code-approved protection.
Seattle FAQ
Does my spa need a pool fence in unincorporated King County?
Not if the spa has a locking, ASTM F1346 safety cover. Without a compliant cover, any spa holding water over 24 inches deep requires a 48-inch barrier with self-closing, self-latching gate.
Can my house wall be part of the pool barrier?
Yes, but doors from the house to the pool must have audible alarms, or the pool must have a powered safety cover. This is inspected at the final building permit sign-off.
