Summary
Huntington Beach's Building Code adds a standalone Chapter 36, 'Building Security,' requiring every entry door on a dwelling unit to carry a keyed dead bolt and deadlocking latch. Under Section 3605, a straight dead bolt must have at least a one-inch throw, and cylinder guards are mandatory wherever a lock cylinder projects beyond the door face or is exposed to gripping tools.
§ 3605. Doors. A. General. A door forming a part of the enclosure of a dwelling unit or of an area of a building occupied by one tenant shall be constructed, installed, and secured as set forth in this section. B. Swinging doors. 1. Swinging wooden doors which can be opened from the inside without using a key shall be of solid core construction. Lights in doors shall be as set forth in this chapter. 2. A single swinging door, the active leaf of a pair of doors, and the bottom leaf of Dutch doors shall be equipped with a dead bolt and deadlocking latch. The dead bolt and latch may be activated by one lock or by individual locks. Dead bolts shall contain hardened inserts, or equivalent, designed to repel cutting tool attack. The lock or locks shall be key operated from the exterior side of the door and engaged or disengaged from the interior side of the door by a device which requires no key, special knowledge or effort. 3. A straight dead bolt shall have a minimum throw of one inch and the embedment shall be not less than five-eighths inch into the holding device receiving the projected bolt.
Full Breakdown
' The dead bolt needs hardened inserts to resist a cutting-tool attack, a straight-bolt throw of at least one inch, and at least five-eighths-inch embedment into the strike; locks that fire two or more bolts at once need only half-inch to three-quarter-inch embedment. Deadlocking latches need a minimum five-eighths-inch bolt projection. Cylinder guards are required on every mortise or rim-type cylinder lock whose cylinder projects past the door face or is otherwise reachable by gripping tools, and hinge pins accessible from outside a closed door must be non-removable.
Section 3604 separately requires main and front entry doors to residential (R) occupancies to give the occupant a view of the area outside without opening the door, through a viewer, view port, or window, with that area lit.
Violations & Fines
Installing or maintaining doors that skip these hardware standards is a Building Code violation, enforceable under Chapter 1.16 like any other Municipal Code offense: a misdemeanor carries up to six months in jail and a $1,000 fine, and an infraction starts at $100 for a first offense, $200 for a second, and up to $500 for later offenses in the same year, plus cost reimbursement. In practice the Building Division checks Chapter 36 hardware before a certificate of occupancy issues.
