Palo Alto FAQ
Are key-locking deadbolts allowed on apartment unit doors?
Single-cylinder deadbolts releasable from inside by thumbturn are fine. Double-cylinder deadbolts requiring a key from inside are prohibited on required egress doors of dwelling units under Section 1010.1.9.3.
Can schools use classroom barricade devices?
Only devices meeting CBC Section 1010.1.9.13 exception language. The lock must release with a single motion, allow free egress, and permit emergency staff access from outside. Aftermarket barricades typically fail review.
San Jose FAQ
Are chains and padlocks ever allowed?
Never on doors serving an occupied space. Chained or padlocked exit doors are an immediate red-tag violation. Storage closets and exterior gates not in the egress path may use padlocks.
Can my retail store use a buzz-in door?
Only if the door still allows free single-action egress from inside. Mag-lock systems require automatic release on fire alarm, sprinkler flow, or power loss, plus a clearly marked manual override button.
