Palm Springs, CA Building Safety: Door Locking Hardware (2026)

170, the special residential building provisions in Article II, Building Security Regulations, requires exterior swinging doors and swinging doors from an attached garage into living space to carry a double- or single-cylinder deadbolt with at least a one-inch bolt projection and three-fourths-inch embedment into the strike, a jamb fastened directly to 2X material, a bolt built to resist cutting-tool attacks, and a cylinder with a cylinder guard, minimum five-pin tumblers, and connecting screws at least one-fourth inch in diameter. The requirement does not apply where panic hardware is required or an equivalent device is approved, and a dual locking mechanism that retracts both deadbolt and latch with one action of the interior knob may substitute if it meets the other specifications.

The same article requires the inactive leaf of double doors to carry flush bolts with at least five-eighths-inch embedment into the head and threshold, and glazing within 40 inches of a door lock to be fully tempered or burglary-resistant unless a double-cylinder deadbolt is installed. 110, pins down every hardware term used, including "bolt projection," "cylinder guard" and "dead latch," so a permit reviewer and an applicant are working from the same specification. 140 separately requires that, on occupancy, each unit in a tract or commercial development use lock combinations interchange-free from every other unit in that development, with written confirmation of compliance filed with the enforcing authority.
