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

Alhambra zoning Section 23.12.150 provides that swimming pools and spas having a depth of more than 18 inches that are not completely enclosed within a building must comply with the standards of that section plus Municipal Code Chapter 9.52. The construction-side barrier requirements come from the city's Swimming Pool and Spa Code (Chapter 20.15), which adopts the California Swimming Pool and Spa Code, and from the statewide Swimming Pool Safety Act (California Health and Safety Code Section 115922). State law requires that when a building permit is issued to construct a new pool or spa, or to remodel an existing one, at a private single-family home, the pool be equipped with at least two of seven listed drowning-prevention safety features. Those features include an isolation enclosure meeting Section 115923 that separates the pool from the home; removable mesh fencing meeting ASTM F2286 with a self-closing, self-latching gate; an approved safety pool cover (ASTM F1346); exit alarms on doors with direct pool access; self-closing, self-latching doors with raised release mechanisms; and an approved pool alarm (ASTM F2208). The local building official must inspect these features before final approval. Because Alhambra defers to this state framework rather than imposing a stricter unique barrier height, the practical standard is the state's enclosure requirements (a code-compliant barrier with a self-latching gate) confirmed against the city's adopted pool code.
