Summary
Pleasanton requires every private swimming pool, spa or hot tub holding more than 18 inches of water to be enclosed by a fence or barrier meeting California Building Code Section 3109. Gates must self-close and self-latch, with the release mechanism on the pool side if it sits below 60 inches. Enforcement runs through the Property Maintenance Code.
Private swimming pools, hot tubs and spas containing water more than 18 inches (457 mm) in depth shall be completely surrounded by a fence or barrier in compliance with Section 3109 in the 2025 California Building Code as applicable. Gates and doors in such barriers shall be self-closing and self-latching. Where the self-latching device is less than 60 inches (1,524 mm) above finished grade or landing, the release mechanism shall be located on the pool side of the gate. Self-closing and self-latching gates shall be maintained such that the gate will positively close and latch when released from an open position of 6 inches (152 mm) from the gatepost. No existing pool enclosure shall be removed, replaced or changed in a manner that reduces its effectiveness as a safety barrier.

Full Breakdown
65, the Pleasanton Property Maintenance Code, most recently amended by Ordinance 2299 on October 21, 2025. The rule applies to any private swimming pool, hot tub or spa on residential property where the water is deeper than 18 inches: the enclosure must comply with Section 3109 of the 2025 California Building Code. Gates and doors set into the barrier must be both self-closing and self-latching. If the latch sits lower than 60 inches above finished grade, the release mechanism has to face the pool side of the gate so someone outside cannot reach it.
The gate must positively close and latch after being released from just 6 inches open, and owners cannot remove, replace or alter an existing enclosure in a way that weakens it as a safety barrier. Spas or hot tubs fitted with a safety cover meeting ASTM F 1346-91 are exempt from the barrier rule entirely. 55, the Pleasanton Swimming Pool and Spa Code (adopted from the 2024 International Swimming Pool and Spa Code, also last amended by Ordinance 2299), separately requires outdoor pool and spa barriers under amended ISPSC Section 305 to meet California Building Code Section 3109 for single-family homes and Section 3119B for public pools, so both chapters point to the same building-code barrier standard for a residential backyard pool.
Violations & Fines
A missing, broken or non-latching barrier is a Property Maintenance Code violation. Under Section 107.4 as amended, each day a violation continues after a notice of violation has been served counts as a separate offense, and any violation of the Property Maintenance Code is also a violation of the Pleasanton Municipal Code, subject to penalties under PMC §§ 1.12.020, 1.24.030 or 1.28.030.
