continuous alarm sounds when any door or window, that permits access from the residence to the pool area that is without any intervening enclosure, is opened or is left ajar. Exit alarms may be battery operated or may be connected to the electrical wiring of the building.

home, the respective swimming pool or spa shall be equipped with at least two of the following seven drowning prevention safety features:
(1) An enclosure that meets the requirements of
Section 115923 and isolates the swimming pool or spa from the private single-family home.
(2) Removable mesh fencing that meets American
Society for Testing and Materials (ASTM) Spec- ifications F2286 standards in conjunction with a gate that is self-closing and self-latching and can accommodate a key lockable device.
(3) An approved safety pool cover, as defined in
subdivision (d) of Section 115921.
(4) Exit alarms on the private single-family home’s
doors that provide direct access to the swim- ming pool or spa. The exit alarm may cause either an alarm noise or a verbal warning, such as a repeating notification that “the door to the pool is open.”
(5) A self-closing, self-latching device with a
release mechanism placed no lower than 54 inches above the floor on the private single- family home’s doors providing direct access to the swimming pool or spa.

or spa, will sound upon detection of accidental or unauthorized entrance into the water. The alarm shall meet and be independently certified to the ASTM Standard F2208 “Standard Safety Specification for Residential Pool Alarms,” which includes surface motion, pressure, sonar, laser and infrared type alarms. A swimming protection alarm feature designed for individ- ual use, including an alarm attached to a child that sounds when the child exceeds a certain distance or becomes submerged in water, is not a qualifying drowning prevention safety feature.
(7) Other means of protection, if the degree of
protection afforded is equal to or greater than that afforded by any of the features set forth above and has been independently verified by an approved testing laboratory as meeting stan- dards for those features established by the ASTM or the American Society of Mechanical Engineers (ASME).
(b) Before the issuance of a final approval for the
completion of permitted construction or remodeling work, the local building code official shall inspect the drowning safety prevention features required by this section and, if no violations are found, shall give final approval. [Amended by Stats. 2017, Ch. 670, Sec. 4. (SB 442) Effective January 1, 2018.]
