Federal Way FAQ
Do I need a fence around my Federal Way hot tub?
If the hot tub has water 24 inches or deeper, yes, unless it has a locking rigid cover meeting ASTM F1346 standards.
How tall does a Federal Way pool fence need to be?
At least 48 inches on the outside face, with no footholds and gates that self-close and self-latch outward from the pool.
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.
