What are the pool fence rules in Santa Clara?

When a building permit is issued for a new pool or spa, or to remodel one at a single-family home, California requires at least two of seven drowning prevention features. If one is a fence, it must be at least 60 inches tall, leave no more than 2 inches at the bottom, block a 4-inch sphere, and have self-closing, self-latching gates that open away from the pool.

What are the seven features?

Health and Safety Code Section 115922 lists them. In plain terms:

1. An enclosure that isolates the pool or spa from the house.
2. Removable mesh pool fencing that meets ASTM F2286, with a self-closing, self-latching gate that can take a key lock.
3. A safety pool cover meeting the listed ASTM standard.
4. Exit alarms on doors and windows that open to the pool area.
5. Self-closing, self-latching devices on those doors, with the release at least 54 inches above the floor.
6. A pool alarm meeting ASTM F2208 (wearable alarms do not count).
7. Other means at least as protective, independently verified.

Two features on the same door, or a safety cover combined with a pool alarm, do not satisfy the requirement.

What are the enclosure specs?

• Minimum height of 60 inches.
• No more than 2 inches between the ground and the bottom of the fence.
• No gap that lets a 4-inch sphere through.
• Gates open away from the pool, close on their own and self-latch, with the latch no lower than 60 inches.
• No climbable handholds or footholds on the outside face.

Does Santa Clara add anything?

The city's zoning code says pools, spas and similar water features must be enclosed in line with the Building Code, and that the required fence around the immediate pool area should not exceed the height the Building Code requires. The barrier is checked with the pool permit.

When does the answer change?

It depends on whether you are pulling a permit. The two-of-seven rule applies at permit time for a new pool or spa, or a remodel at a single-family home. An existing pool with no new permit may not trigger it, but a proper barrier is still one of the best protections for young children.

Which fences meet the specs most easily?

Powder-coated aluminum with narrow picket spacing is the usual choice. Smooth-faced vinyl also works. Horizontal rails on the outside face are a problem because children can climb them. See pool fences.
