Summary

In the City of Lacey, Washington, every unit in a rental complex of five or more dwelling units must have single-cylinder deadbolts on all exterior hinged doors, a reinforced 4-inch strike plate, a door viewer with at least a 180 degree field of vision, and secondary locks on sliding doors and windows. The rule sits in Section 425 of the city's amended building code.

In all rental unit complexes consisting of five or more dwelling units, each unit shall be provided with the following crime prevention devices and design considerations: 1. Security locking devices: a. Single-cylinder deadbolt locks on all exterior hinged doors; b. A reinforced 4-inch strike-plate attached to the wood framing by not less than two No. 8 by 3-inch screws; c. A door viewer having a field of vision of not less than 180 degrees; d. Secondary security locking device on all sliding doors in addition to the factory-provided door locking device; e. Secondary security locking device on all sliding windows in addition to the factory-installed sash-type lock; f. Secondary security locking device on all crank-type or jalousie windows separate from the factory-installed crank device. All secondary security locks must meet the requirements of Section 310.4, to be openable without keys, any special knowledge or effort.

Full Breakdown

Lacey Municipal Code § 14.04.015 adds Section 425 to the International Building Code as adopted in the City of Lacey. It applies in all rental unit complexes consisting of five or more dwelling units, and each unit must be provided with the listed crime prevention devices. The security locking list requires single-cylinder deadbolt locks on all exterior hinged doors and a reinforced 4-inch strike-plate attached to the wood framing by not less than two No. 8 by 3-inch screws. Each unit also needs a door viewer with a field of vision of not less than 180 degrees.

Sliding doors and sliding windows each need a secondary security locking device in addition to the factory-provided or factory-installed lock. Crank-type or jalousie windows need a secondary device separate from the factory crank. All secondary security locks must meet Section 310.4, meaning they are openable without keys, any special knowledge or effort, so the added hardware cannot trap an occupant.

Section 425 goes beyond locks. Walkways, hallways, stairwells and entry areas need lighting giving a minimum of one foot-candle at floor or ground level, entrance foyers need three foot-candles, and parking lot lighting must run on timers or photo-electric switching that turns on at dusk. Fences must provide through-visibility and sight-obscuring fencing is not permitted. The complex must post address numbers, a site map at the entrance, and a sign reading “No Trespassing On This Property. LMC 9.28.080 - .090.”

A separate certificate of occupancy prerequisite in the same section requires a property of five or more dwelling units in one complex to be registered in the Residential Building Rental Registration Program under Chapter 14.02.

Violations & Fines

Any violation of the International Building Code as adopted in the City of Lacey, including the Section 425 amendments, is a misdemeanor under Lacey Municipal Code § 14.04.020. The building official enforces the code and can withhold a certificate of occupancy until the listed prerequisites are met.

Frequently Asked Questions

Which rental properties in Lacey must have deadbolts under Section 425?
Section 425 covers rental unit complexes consisting of five or more dwelling units, and it requires each unit to have single-cylinder deadbolt locks on all exterior hinged doors. The text sets the threshold at five or more dwelling units, so the requirements are written for complexes rather than for a single rented house in the City of Lacey.
What does the strike plate have to look like?
It must be a reinforced 4-inch strike-plate attached to the wood framing by not less than two No. 8 by 3-inch screws. The code pairs it with the deadbolt, so the plate and the screws are part of the required security locking devices for each unit, not an optional upgrade.
Can a secondary lock on a sliding door need a key?
No. All secondary security locks must meet Section 310.4, which the code states as being openable without keys, any special knowledge or effort. That applies to the extra devices on sliding doors, sliding windows and crank-type or jalousie windows, so occupants can still exit quickly.
Does Section 425 limit fences at an apartment complex?
Yes. All fences constructed must provide through-visibility, and sight-obscuring fencing is not permitted. The same item states that fences in Group R, Division 2 Occupancies are not exempt from building permit requirements, so even a low fence at such a complex goes through the building permit process.
