Cupertino, CA Swimming Pools & Spas: Fencing & Safety Requirements (2026)

140. Under the adopted Section 115922(a), when a building permit is issued for construction of a new pool or spa, or the remodeling of an existing swimming pool or spa, at a private single-family home, the pool or spa must be equipped with at least two of seven listed drowning prevention safety features. Those options include an enclosure isolating the pool from the home under Section 115923, removable mesh fencing meeting ASTM F2286 with a self-closing, self-latching gate, a power-operated safety cover meeting ASTM F1346-23, exit alarms on doors and windows leading to the pool area, a self-closing, self-latching door device with a release mechanism mounted no lower than 54 inches above the floor, and a pool-entry alarm certified to ASTM F2208.

Section 115922(b) specifies that certain combinations do not satisfy the requirement, such as an exit alarm paired with a self-closing, self-latching device on the same door, or an exit alarm paired with a door latch on separate doors. Before final approval of the permitted construction or remodeling, Section 115922(c) requires the local building official to inspect the required drowning safety prevention features and confirm no violations exist before signing off on the project.
