Anaheim FAQ
Do I need a permit for an above-ground pool in Anaheim?
Yes. All pools require building permits and compliant barriers per AMC 6.56 regardless of whether they are above-ground or in-ground.
Do above-ground pools need fencing?
Yes. Pool barriers are required for all pools. Above-ground pools with walls under 48 inches need additional fencing to meet minimum height.
Costa Mesa FAQ
Do I need a permit for an above-ground pool in Costa Mesa?
Yes if the pool can hold more than 18 inches of water. Under California Health and Safety Code Section 115921 it is treated as a swimming pool, and the California Residential Code adopted in CMMC Title 5 requires a building permit and inspection. Smaller portable wading pools under 18 inches are not regulated as pools, but the city may still treat repeated use as a nuisance. Confirm thresholds with the Costa Mesa Building Division at (714) 754-5273.
How tall does the fence around my above-ground pool need to be?
California Health and Safety Code Section 115923 requires any pool isolation barrier to be at least 60 inches tall measured from the outside, with no more than a 2-inch gap at the bottom, no openings that allow a 4-inch sphere through, and no climbable footholds within 60 inches of the top. The pool wall itself can serve as part of the barrier only if it meets these standards. Gates must be self-closing and self-latching with the release at least 60 inches above grade.
What safety features does Costa Mesa require for a new pool?
Under California Health and Safety Code Section 115922, any new or remodeled residential pool, including an above-ground pool over 18 inches deep, must have at least two of seven approved drowning-prevention features: an isolation enclosure, removable mesh fencing meeting ASTM F2286, an ASTM F1346 safety cover, exit alarms on doors leading to the pool, an approved self-closing self-latching door device, an ASTM F2208 pool alarm, or another approved means. The Costa Mesa Building Division verifies these at final inspection.
