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

030. 020 limits the chapter's scope to new buildings for which permit applications are filed after the ordinance's effective date, plus any building undergoing additions, alterations, or repairs exceeding 75 percent of its value on the county assessor's tax rolls. 080 sets the nonresidential hardware standard: locking devices for exterior doors must meet the Uniform Building Code and Titles 19 and 24 of the California Code of Regulations, and where allowed, a single-cylinder deadbolt must be installed with the latch set so both retract with a single-hand motion.

Swinging wood or steel exterior doors need a deadbolt with a minimum one-inch bolt projection, three-quarter-inch embedment into the strike, a cylinder guard, and a minimum of five pin tumblers built to repel cutting-tool attacks; double doors additionally need an inactive-leaf flush bolt and a minimum one-eighth-inch steel astragal covering the gap between doors. Aluminum-frame swinging doors must have jambs able to withstand sixteen hundred pounds of pressure near the strike. 100 apply comparable deadbolt-and-latch requirements to hotel, motel, multifamily, duplex, and single-family entrance doors, generally requiring solid-core construction with a minimum rail and stile thickness around one and three-eighths to one and three-quarters inches.
