Palo Alto FAQ
Does my existing pool need a 60 inch fence?
Only if a remodel triggers the statute; older pools are governed by the rules in effect when permitted.
Is a pool cover by itself enough?
No. State law requires at least two approved features, not just a cover.
San Jose FAQ
Do I need a permit to install or replace a pool fence in San Jose?
Yes. Pool construction, remodels, and barrier installations require a building permit through San Jose Planning, Building & Code Enforcement. Inspectors verify the 60-inch barrier, the 4-inch gap rule, the 60-inch latch height, and the two required drowning prevention features under HSC §115922 before final approval.
Can San Jose require a stricter pool barrier than the state minimum?
San Jose adopts the California Building Code §3109 and the Swimming Pool Safety Act through Title 17 (Building) and Chapter 17.28. The 60-inch minimum height, 2-inch ground clearance limit, and 4-inch gap rule are state-set floors and apply citywide; San Jose enforces these through permit review and inspection.
