Summary

The City of La Mesa requires every exterior door and garage-entry door on a single-family dwelling to carry a deadbolt in addition to a deadlocking latch under La Mesa Municipal Code Section 14.07.040, with both retractable by one motion of the interior door knob, as part of Chapter 14.07's detached-dwelling security standards.

A.Exterior doors and doors leading from garage areas into single-family dwellings shall be of solid core as per the specifications set forth in the Uniform Building Code, 1976 Edition.B.Exterior doors and doors leading from garage areas into private family dwellings shall have deadbolts in addition to deadlocking latches. The locks shall be so constructed that both deadbolt and deadlocking latch can be retracted by a single action of the inside door knob. Alternate devices equally able to resist illegal entry may be substituted subject to prior approval of the Building Official.

Full Breakdown

Chapter 14.07, the city's Security Ordinance, sets minimum hardware standards administered by the Director of Building Inspection and Housing under Section 14.07.030. For detached dwellings, Section 14.07.040 requires exterior doors and doors leading from garages into single-family homes to be solid core per the 1976 Uniform Building Code, and to carry deadbolts in addition to deadlocking latches, both released by a single action of the interior knob unless the Building Official approves an equally secure alternate device. The same section requires non-removable hinge pins on out-swinging doors, rabbited jambs on in-swinging doors, burglary-resistant vision panels, mail slots no larger than 24 square inches with interior knob protection if within 3 feet of a lock, and flush extension bolts with a three-quarter-inch throw on the inactive leaf of double doors.

Section 14.07.050 separately requires sliding patio doors to have a keyed, pin-tumbler dead lock with inaccessible mounting screws and a bolt able to withstand 800 pounds of force, and Section 14.07.060 requires overhead or accordion garage doors without electric power to be secured with a cylinder lock, padlock, or slide bolt using non-removable exterior fasteners. Section 14.07.070 requires ground-level windows to be lockable so they cannot be lifted from the frame and to resist 300 pounds of force, and bars louvered windows outright. Multifamily buildings, hotels, motels, and apartments face parallel deadbolt, self-closing, and key-box rules under Sections 14.07.100 through 14.07.140, and non-residential buildings face separate double-cylinder deadbolt and door-glazing standards under Sections 14.07.180 and 14.07.190.

Appeals go to the board established under Section 204 of the 1976 Uniform Building Code, sitting as the board of appeals for the Security Ordinance under Section 14.07.230.

Violations & Fines

Chapter 14.07 does not print its own fine schedule in the text reviewed; because building-related code violations are carved out of the infraction default in the general penalty clause, Section 1.01.080 classifies violations of the building code, which the security ordinance sits within, as misdemeanors punishable by up to a $1,000 fine, six months in San Diego County jail, or both, unless a different penalty is specified.

Frequently Asked Questions

Do all La Mesa homes need a deadbolt on every exterior door?
Section 14.07.040 requires it for single-family dwellings: every exterior door and every door leading from a garage into the home must have a deadbolt in addition to a deadlocking latch, both operable together by one action of the interior knob, unless the Building Official approves an equally secure alternate.
What force must a La Mesa sliding patio door lock withstand?
Section 14.07.050 requires the lock bolt on a sliding patio door to be hardened steel or contain hardened steel inserts capable of withstanding 800 pounds of force applied in any direction, with mounting screws inaccessible from the outside. The section also requires a keyed, pin-tumbler bored cylinder operable from the outside, and on double sliding doors, the meeting rail itself must lock and meet those same strength requirements.
Are louvered windows allowed under La Mesa's security code?
No. Section 14.07.070 bars louvered windows on detached dwellings outright, and the same prohibition is repeated for multifamily buildings under Section 14.07.140 and applies to ground-floor or otherwise accessible openings covered by the chapter. Any window the rule does allow must still be built so it cannot be lifted from its frame when locked and must resist 300 pounds of force applied in any direction.
