Antioch FAQ

Do I need a permit for an above-ground pool in Antioch?

Permits may be required for larger pools or those with permanent electrical connections. Check with the Building Division.

Does my above-ground pool need a fence in Antioch?

If walls are 60+ inches and the ladder is removable, walls may serve as the barrier. Otherwise, a separate 60-inch fence is needed.

Walnut Creek FAQ

Do I need a permit for an above-ground pool in Walnut Creek?

Only if the prefabricated pool walls exceed 24 inches or capacity exceeds 5,000 gallons. Beyond either threshold, the Walnut Creek Permit Center requires a building permit reviewed under the California Building Standards Code.

How tall does the pool fence have to be in Walnut Creek?

Walnut Creek requires at least a 54-inch fence with a self-latching gate around any swimming pool, and the fence must comply with the California Building Code or Residential Code. Note that California's Pool Safety Act sets a 60-inch enclosure benchmark for new and remodeled pools.

Does the wall of my above-ground pool count as the required fence?

Only if the pool's perimeter wall is non-climbable, has gaps no larger than 4 inches, and any access ladder or step has a self-closing, self-latching gate opening away from the pool. Most stock above-ground pool walls do not meet these criteria on their own.

What does SB 442 require for a new pool?

California Health and Safety Code 115921 et seq. requires at least two of seven approved drowning-prevention features at any new or remodeled residential pool at a single-family home, including a 60-inch enclosure, removable mesh fencing, an approved safety cover, exit alarms, or self-closing and self-latching pool doors.
