Los Angeles's Swimming Pools & Spas: The Rules That Matter
Every city handles swimming pools & spas a little differently. In Los Angeles, California, there are 5 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.
Pool Permits
A building permit from LADBS is required for construction of any in-ground or permanent above-ground swimming pool. Electrical and plumbing permits are also needed. Plans must show barrier compliance, drainage, and setbacks. Pools in hillside areas may require additional grading permits. Express permits are available for simple installations meeting standard criteria.
Key details: Building Permit: Required for all pools. Additional Permits: Electrical and plumbing. Hillside: Grading permit may be needed. Express Permit: Available for standard installs. Agency: LADBS.
Building without a permit subjects owners to LADBS enforcement, potential fines, and orders to remove or modify non-compliant construction. Unpermitted pools may affect property insurance and sale transactions.
Above-Ground Pools
Above-ground pools with water 18+ inches deep are subject to the same barrier requirements as in-ground pools under LAMC 91.6109. If the pool structure itself serves as the barrier, the ladder or steps must be removable or surrounded by a separate barrier. Portable pools under 18 inches deep are exempt from barrier requirements but still subject to water safety rules.
Key details: Barrier Required: Yes, if water 18+ inches deep. Structure as Barrier: Ladder must be removable/secured. Under 18 Inches: Exempt from barrier rules. Code Section: LAMC 91.6109.
Unpermitted pools: removal or retroactive permit with double fees. Safety violations: immediate correction required. Fines $100 to $500.
Fencing Requirements
LAMC 91.3109 and 91.6109 require residential pool barriers at least 60 inches high with self-closing, self-latching gates. Openings may not allow passage of a 4-inch sphere. At least 2 of 7 drowning prevention safety features required for new pools including mesh fencing, safety covers, or exit alarms. The barrier must be non-climbable with no horizontal members less than 45 inches apart on the outside.
Key details: Height: 60 inches minimum. Gates: Self-closing, self-latching. Safety Features: 2 of 7 required for new pools. Anti-Climb: No horizontal members under 45 in. apart. Code Section: LAMC 91.3109, 91.6109.
LADBS enforces pool barrier requirements. Non-compliant barriers must be corrected. Unpermitted modifications to pool fencing can result in stop-work orders and fines.
Compared to other cities, Los Angeles takes a harder line on fencing requirements. The enforcement and penalty structure reflects that.
Safety Rules
CA Swimming Pool Safety Act (H&S Code 115920-115929) applies in LA. All new residential pools require at least 2 drowning prevention features. Drain covers must comply with the federal Virginia Graeme Baker Act. Pool equipment must meet Title 24 energy standards. Public pools have additional requirements including 5-foot barriers and regular health inspections.
Key details: State Law: CA H&S Code 115920-115929. Drowning Prevention: 2 of 7 features required. Drain Covers: VGB Act compliant. Public Pools: 5 ft barrier, health inspections. Energy: Title 24 pool equipment standards.
LADBS and the LA County Department of Public Health enforce pool safety requirements. Non-compliant pools face orders to install required safety devices. Public pool violations may result in closure until compliance is achieved.
This is one of the stricter rules in Los Angeles's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.
Hot Tub Rules
Hot tubs, spas, and portable spas are included in the LAMC definition of swimming pool and are subject to the same barrier and safety requirements when containing 18+ inches of water. Covers meeting ASTM F1346 can serve as one of the required drowning prevention features. A lockable safety cover may reduce but not eliminate barrier requirements. Electrical installation requires a permit.
Key details: Classification: Treated as swimming pool under LAMC. Barrier: Required if 18+ inches of water. Safety Cover: Counts as 1 of 7 safety features. Electrical: Permit required for installation.
Unpermitted electrical work: fines and required correction. Drainage violations: remediation required. Safety cover violations: immediate correction.
