Location Requirements
- Per City Code Section 36.12.55, all swimming pools must be located at least five (5) feet from any property line. Any pool equipment must be at least three (3) feet from any property line.
- If the location of the swimming pool is near windows or glass doors, the applicant must verify compliance with CRC R308.4.5 glazing and wet surfaces requirements.

- Overhead electrical conductors/wires located over the swimming pool and within 10 feet horizontally of the pool must be a minimum of 22.5 feet above the maximum water level and 14.5 feet above any diving platform (CEC table 680.9(A)).
Safety Requirements
- In order to prevent drowning, safety features are required to be installed to restrict unauthorized access to the pool from the house and from the public sidewalk. All private swimming pools must be equipped with at least two of the following safety features to limit access from both the house and from the public sidewalk:
- An enclosure that isolates the swimming pool or spa from the private single-family home and meets the following requirements:
- Gates must open away from the swimming pool with open devices placed no lower than 60 inches above the ground; gates must be self-closing and self-latching.
- Enclosure must be a minimum of 60 inches in height.
- A vertical clearance from the ground to the bottom of the enclosure must be 2 inches maximum.
- If there are any gaps or voids in the enclosure, the gap cannot allow a sphere equal or greater than 4 inches in diameter to pass through.
- The enclosure must not have any protrusions, cavities or other characteristics that would serve as handholds or footholds.
- Removable mesh fencing that meets American Society for Testing and Materials (ASTM) Specifications F2286 standards in conjunction with a self-closing and self-latching gate that can accommodate a key lockable device.
- An approved safety pool cover that meets all the requirements of the ASTM Specifications F1346-91.
- Exit alarms on the private single-family home’s doors that provide direct access to the swimming pool. The exit alarm may either be an alarm noise or a verbal warning, such as a repeating notification that “the door to the pool is open."
- 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 that provide direct access to the swimming pool.
- An alarm that, when placed in a swimming pool, will sound upon detection of accidental or unauthorized entrance into the water. The alarm must meet all the requirements for ASTM Specifications F2208. Note: Swimming pool alarms do not include swimming protection alarm devices designed for individual use, such as an alarm attached to a child that sounds when the child exceeds a certain distance or becomes submerged in water.
- An enclosure that isolates the swimming pool or spa from the private single-family home and meets the following requirements:

- Where none of the bonded parts is in direct connection with the pool water, the pool water must be in direct contact with an approved corrosion-resistant conductive surface that exposes a minimum of 9 square inches of surface area to the pool water at all times. The conductive surface must be located where it is not exposed to physical damage or dislodgment during usual pool activities and it must be bonded as noted above (CEC 680.26(C)).
