Summary

Swimming pools at private single-family homes in San Francisco must comply with the California Swimming Pool Safety Act (Health and Safety Code Sec. 115920-115929). When a building permit is issued for a new or remodeled pool or spa, the property owner must install at least two of seven approved drowning prevention safety features. Compliance is verified at final inspection by the Department of Building Inspection. The California Building Code (CBC Sec. 3109) further governs pool barrier construction standards.

115923. An enclosure shall have all of the following characteristics:

(a) Any access gates through the enclosure open away from the swimming pool, and are self-closing with a self-latching device placed no lower than 60 inches above the ground.

(b) A minimum height of 60 inches.

(c) A maximum vertical clearance from the ground to the bottom of the enclosure of two inches.

(d) Gaps or voids, if any, do not allow passage of a sphere equal to or greater than four inches in diameter.

(e) An outside surface free of protrusions, cavities, or other physical characteristics that would serve as handholds or footholds that could enable a child below the age of five years to climb over.

Full Breakdown

California Health and Safety Code Sec. 115922 requires that any new or remodeled swimming pool or spa at a private single-family home incorporate at least two of the following seven safety features: (1) a perimeter enclosure (fence, wall, or barrier) that isolates the pool from the home and meets standards in Sec. 115923; (2) removable mesh fencing meeting ASTM International F2286 with a self-closing, self-latching gate; (3) a manually or power-operated safety pool cover meeting ASTM International F1346-23; (4) exit alarms on the home's doors and windows providing direct pool access, producing an audible continuous alarm or repeating verbal warning; (5) a self-closing, self-latching device with a release mechanism placed no lower than 54 inches above the floor on doors with direct pool access; (6) a water immersion alarm meeting ASTM F2208 standards that sounds upon detection of accidental entry; or (7) other equivalent protection certified by an independent approved testing laboratory.

Certain feature combinations are prohibited (for example, combining an exit alarm and a self-closing device on the same door does not satisfy the two-feature requirement). The California Building Code Sec. 3109 sets construction standards for pool barriers. The San Francisco Department of Building Inspection enforces these requirements during permit review and final inspection. Owners are responsible for keeping all selected safety features in good repair and operable as designed.

Violations & Fines

Failure to comply with the Pool Safety Act can result in denial of permit final inspection and orders to abate from the San Francisco Department of Building Inspection. Permits will not be finalized until at least two qualifying safety features are installed and verified. Civil liability for drowning incidents may also apply where required barriers or alarms were absent or inoperable. Contact the SF Department of Building Inspection for specific enforcement procedures.

Frequently Asked Questions

Does this apply to existing pools?
The two-feature requirement is triggered when a building permit is issued for a new pool or spa or for remodeling an existing one.
Can I just install a pool cover?
No. A safety pool cover counts as one feature; you must install a second qualifying feature, and the cover must meet ASTM F1346-23.
