Kirkland FAQ
Does Kirkland require a fence around my pool?
Yes. Any pool or spa deeper than 24 inches needs a 48-inch compliant barrier under the Washington State Building Code and IRC Appendix G.
Can a pool cover replace the fence?
Not for a swimming pool. Only rigid locking safety covers meeting ASTM F1346 on hot tubs and spas qualify as an alternative to the full barrier.
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.
