Altadena FAQ
Do I need a permit for an above-ground pool in LA County?
Yes, if it holds 3,000+ gallons or is deeper than 24 inches. Smaller temporary pools don't need a permit but still need safety barriers. Contact Building & Safety at (626) 458-3171.
Do above-ground pools need a fence?
Yes. All pools, including above-ground, must have safety barriers under the CA Swimming Pool Safety Act. If the pool walls are at least 5 feet with a lockable ladder, they may partially satisfy the barrier requirement.

Pool water should be drained to a sanitary sewer cleanout, not to the street or storm drain. Chlorinated water in storm drains harms aquatic life and violates environmental regulations. Contact your sewer utility for guidance.
