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

010 as providing a minimum level of resistance to unlawful entry through minimum design and maintenance standards for security equipment, while still allowing alternate devices the police department approves as equally secure. 050. 140: solid-core doors at least 1-3/8 inches thick, a self-locking deadlatch plus a one-inch-throw deadbolt keyed alike to the deadlatch so one key fits both, and a locking device on main entrance doors letting both the deadbolt and deadlatch retract with a single inside-doorknob action. The same section also requires cylinders resistant to gripping by pliers or wrenching tools, locks operable from inside without a key, flush bolts with a 5/8-inch throw top and bottom on the inactive leaf of paired doors, one-piece or rabbet-jointed door stops on wood jambs for in-swing doors, hinges accessible only from inside when the door is closed, and anti-lift devices on sliding doors. 080, which separately requires hardened-steel deadbolt inserts and specific hardware for overhead and accordion-type doors. 22 LMC.
