Bellevue FAQ
Does a pool cover replace a fence in Bellevue?
No. Pool covers do not replace a 48-inch barrier. Only rigid locking safety covers meeting ASTM F1346 on hot tubs and spas qualify as an alternative.
Do I need a fence around an above-ground pool?
Yes, if water depth exceeds 24 inches. The pool wall may serve as the barrier if at least 48 inches tall and the ladder is removable or lockable.
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.
