If you live in Folsom or are thinking about moving there, swimming pools & spas are one of those things you probably won't think about until they affect you directly. Folsom has 5 specific rules on the books covering different aspects of swimming pools & spas, and some of them might surprise you.
Hot Tub Rules
Hot tubs and spas in Folsom require a building and electrical permit unless the unit is portable, UL-listed, and has a lockable safety cover meeting ASTM F1346 in lieu of fencing. Electrical must include GFCI protection and bonding.

Safety Rules
California HSC §115922 requires pools built or remodeled after January 1, 2018 to have at least TWO of seven approved safety features: enclosing fence, safety cover, removable mesh, exit alarms on doors, pool alarm, self-latching devices on doors, or other ASTM-approved drowning prevention.

Sale without proper inspection/disclosure: Civil Code §1102 penalties. Non-compliant pool: cannot be filled/used.
This is not one of those rules that cities tend to ignore. Folsom actively enforces its safety rules requirements.
Above-Ground Pools
Folsom treats above-ground pools over 18 inches deep the same as in-ground pools for barrier and permit purposes. The wall of the pool may serve as part of the barrier if at least 60 inches high; ladders must be removable or lockable when not in use.
