Berkeley, CA Building Safety: Door Locking Hardware (2026)

BMC Chapter 19.80, Minimum Security in the City of Berkeley, applies to Group R-1, R-3, and M occupancies, exempting enclosed Group M space not used for dwelling or lodging (§ 19.80.020). Section 19.80.030 reaches every exterior door of a rental dwelling unit, or of an area occupied by a single tenant, that is directly accessible from a street, yard, court, passageway, corridor, balcony, patio, breezeway, or garage, and extends to hotels, motels, and boarding and lodging houses. Section 19.80.050 sets the hardware specification: a 1-inch single-cylinder deadlock with a hardened cylinder guard, key-operated from outside and turnpiece- or knob-operated from inside; a deadlocking latch with a guarded bolt; deadbolts with hardened inserts to resist a cutting-tool attack; non-removable hinge pins that are welded, flanged, or screw-secured; and strike plates fastened with screws at least 2.5 inches long, shorter only where the jamb itself is steel or set in concrete or masonry.

Section 19.80.060 applies a nearly identical specification to shared entry doors, stairwells, lobbies, and garages in hotels and apartment houses of two or more stories or more than four units, and additionally requires that both the deadbolt and latch retract with a single turn of the interior knob on main tenant exit doors. Locking devices installed before December 9, 1973 are grandfathered if the building official finds them equivalent in security (§ 19.80.070B), and any alternative device can be approved if it provides equivalent security, with an appeal of a denial running through § 19.44.020.

Owners, or their authorized managing agents, bear responsibility for compliance under § 19.80.080, and § 19.80.090 makes clear the City has no duty to inspect and no liability for failing to catch a noncompliant lock.
