Pittsburg FAQ

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

Yes. Pools deeper than 18 inches or larger than 250 square feet require a building permit through the Pittsburg Permit Center and must comply with Municipal Code Chapter 15.56 fencing rules and the California Building Standards Code.

What kind of fence does my above-ground pool need?

Pittsburg MC 15.56 requires a fence or wall at least 5 feet high completely surrounding the pool, with no horizontal openings larger than 4 inches. Gates must be self-closing and self-latching. The pool wall itself can serve as the barrier only if it meets these standards.

Are there exemptions from the pool fencing rule?

Pools shallower than 18 inches and smaller than 250 square feet are not subject to Chapter 15.56. Doors of an occupied dwelling are exempt from the self-closing requirement, but garage back doors and breezeway doors that lead to the pool area must be self-closing and self-latching with the latch at least 4 feet 10 inches high.

What does California's SB 442 add on top?

California Health and Safety Code 115921 et seq. requires any new or remodeled residential pool at a single-family home to include at least two of seven approved drowning-prevention features, such as a 60-inch enclosure, removable mesh fence, approved safety cover, or self-closing pool-area doors with alarms.

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.
