Los Angeles FAQ
Can teachers use barricade locks during a lockdown?
Only if the device meets ANSI A156.41, unlocks with one motion from inside, and allows outside override by staff. Improvised wedges and door-blockers violate LABC and CFC.
Are double-cylinder deadbolts allowed at home?
On a single-family home main door, yes if no group sleeps above. Apartments, ADUs, and any required exit door must use thumb-turn or single-action hardware only.
Palmdale 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 §1010.1.9.3.
Can schools use classroom barricade devices?
Only devices meeting CBC §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.
