Lacey, WA Building Safety: Carbon Monoxide Detectors (2026)

LMC 14.14.025(G) is where the City of Lacey code addresses carbon monoxide alarms by name. It sits in Chapter 14.14, the manufactured home standards chapter, and covers recreational park trailers and recreational vehicles installed within a manufactured home park under RCW 35A.21.312. A working CO alarm must be installed per NFPA 1192 Current Edition, Section 6.4.6 for a recreational vehicle, or per ANSI A119.5 Current Edition, Section 3-5 for a recreational park trailer.

The CO alarm is one of eight conditions in the same subsection. The unit also needs a working smoke detector (NFPA 1192 Section 6.3 or ANSI A119.5 Section 3-3) and egress directly from the sleeping area through a door or an egress window with a minimum size of 24 x 17. The electrical cord must be protected within rigid conduit. The unit connects to the water supply and the sanitary sewer system provided within the park, under the adopted uniform plumbing code with all applicable fees paid. Steps, landings, stairways, decks and balconies must meet the International Residential Code and be independently supported. Each unit needs an internal toilet and internal shower, or the park must provide a common toilet and shower facility.

Installation also needs a permit. LMC 14.14.020 bars installing a recreational park trailer or recreational vehicle without complying with the adopted standards or without an installation permit from the city, issued after the owner or installer applies on city forms and pays a fee set by the city council. Under LMC 14.14.030 the city inspects each permitted installation and does not permit occupancy until inspection and approval are given.
