5 rules for unincorporated Lake County, California.
Verified from official government sources
Unincorporated Lake County requires a building permit through the Community Development Department's Building & Safety Division for private swimming pools and spas. Pools are regulated under 2019 California Building Code Section 3109, as modified by the County, and contractors must give buyers the state pool-safety notice.
In unincorporated Lake County, a private pool must be enclosed by a fence or wall at least 60 inches high with gaps that won't pass a 4-inch sphere. Gates must be self-closing and self-latching with the latch at least 60 inches above the ground. These rules follow CBC 3109.4 as modified by the County.
Unincorporated Lake County requires a pool to be isolated from the home by at least one approved method before filling: a compliant enclosure, removable mesh fencing, an ASTM F1346 safety cover, door exit alarms, self-latching doors, or an ASTM F2208 pool alarm. The intent is to prevent unsupervised child access.
In unincorporated Lake County, above-ground pools are treated as swimming pools whenever they hold water over 18 inches deep. The County's barrier handout expressly includes above-ground structures, so the same 60-inch fence/Part A and Part B isolation requirements and building permit apply.
In unincorporated Lake County, a self-contained hot tub or spa with a locking safety cover meeting ASTM ES 13-89 (ASTM F-1346) is exempt from the pool fence requirement. Non-self-contained spas are treated as swimming pools and must meet the full enclosure and isolation rules.
