Backyard pools are common on the Peninsula, from ranch lots in Mountain View and Sunnyvale to estates in Atherton and the hill towns. The barrier around one is set by state law. California's Swimming Pool Safety Act describes the enclosure in Health and Safety Code section 115923: at least 60 inches high, no more than 2 inches of clearance at the bottom, no gap that passes a 4 inch sphere, and an outside face with nothing a small child could use to climb.
Gates are where most barriers fail inspection. The law requires access gates to open away from the pool and to close and latch on their own, with the latch at least 60 inches above the ground. We use aluminum or steel picket panels for most pool fences because they keep the yard open, do not rot and take self-closing hinges well. Where an Eichler's glass wall faces the pool, owners often prefer mesh or glass panels to keep the view.
Your city's building department inspects the barrier when a pool or spa is built or remodeled, and it can add local requirements. In Mountain View a metal fence needs a building permit of its own. In the hill towns the town fence permit applies on top of the state rule, and a tall solid enclosure may have to sit well inside the lot. We lay out the barrier with the pool contractor so the gate swings, equipment access and house doors all work together.
Pool fences in Mountain View: common questions
How tall does a pool fence have to be in Mountain View?
California's Swimming Pool Safety Act sets a minimum of 60 inches for an enclosure used as the pool barrier, with self-closing, self-latching gates that open away from the pool. Mountain View's Building Division inspects it under the pool permit and can tell you about any added local rule.
Can my existing wood back fence serve as the pool barrier?
Only if it meets every state requirement: 60 inches high, no more than 2 inches of gap under it, no opening a 4 inch sphere fits through, nothing climbable on the outside, and gates that comply. Old board fences often fail on gaps and gates. We can check yours on site.
My pool gate does not close by itself anymore. Can you fix only the gate?
Yes. New self-closing hinges, a latch set at the required height and a gate re-hung to swing away from the water are routine repairs. If the gate post has moved, we reset it first, because hardware will not hold on a leaning post.
