Smoke Alarms/Carbon Monoxide Alarms
Smoke Alarms shall be listed and labeled in accordance with UL 217 and installed according to the manufacturer’s listing and installation/operating instructions and in accordance with the household fire warning equipment provisions of NFPA 72.

New Construction 

All new construction, including alterations, repairs and additions, as well as the unaltered existing portion of the residence, require "interconnected" (the actuation of one alarm will activate all alarms in the entire residence including habitable detached casitas), hard-wired smoke alarm devices with battery backup (see exceptions as noted in section R314.3.1, I.R.C.). These smoke alarm devices shall be installed in the following locations:

  • In each sleeping room
  • Outside each separate sleeping area in the immediate vicinity of the bedrooms
  • On each additional story of the dwelling, including basements, but not including crawl spaces and uninhabitable attics. In dwellings or dwelling units with split levels and without an intervening door between the adjacent levels, a smoke alarm device installed on the upper level shall suffice for the adjacent lower level provided that the lower level is less than one full story below the upper level
  • Where adjacent ceiling heights vary 24 inches or more, or where door openings and archways drop down 24 inches or more from the adjoining ceiling height


Existing Construction
The City highly recommends that all existing habitable residential buildings, constructed prior to the requirements for smoke alarm protection, be equipped with a level of smoke alarm protection. The smoke alarm devices may be battery operated and are to be located in the same locations as noted above (see “New Construction”).

Carbon Monoxide Alarms
An invisible killer could be lurking in your home.  You can't see it or smell it, but it can quickly incapacitate you and your family.  This invisible silent killer is carbon monoxide (CO).  Carbon monoxide is a poisonous gas that can result from faulty, improperly used or incorrectly vented fuel-burning appliances such as furnaces, generators, stoves, water heaters, fireplaces or cars.
 

Carbon monoxide
alarms shall be listed and labeled in accordance with UL 217, "Single and Multiple Station
Carbon monoxide (CO) Alarms".  As an alternate to self-contained CO alarms, a household carbon monoxide detection system installed in accordance with NFPA 720, "Standard for the Installation of Carbon Monoxide (CO) Detection and Warning Equipment" may be used
.

**Please note:  A household CO detection system must be owned by the homeowner and monitored by an approved supervising station.

New Construction

For new construction, an approved carbon monoxide alarm shall be installed outside of each separate sleeping area in the immediate vicinity of the bedrooms in dwelling units within which fuel-fired appliances are installed and in dwelling units that have attached garages.

Existing Construction
The City highly recommends that all existing habitable residential buildings, constructed prior to the requirements for carbon monoxide (CO) protection, be equipped with a level of CO alarm protection.  The CO alarm devices may be battery operated and are to be located in the same locations as noted above (see "new Construction").  Know the symptoms of CO poisoning:  headache, dizziness, weakness, nausea, vomiting, sleepiness and confusion.


***Please note: All smoke alarm devices (battery operated and hard-wired with battery backup) must be checked periodically for proper operation and batteries replaced at least once a year.
