This chapter is enacted for the purpose of protecting the health and safety of the residents of the County, its visitors and employees, by requiring operable carbon monoxide detectors in existing residential occupancies thereby hopefully reducing the number of injuries and fatalities resulting from carbon monoxide (CO) poisoning.
The provisions of this ordinance shall apply to: 1) all new residential construction containing a sleeping unit; 2) additions to residential buildings containing a sleeping unit; 3) remodels of residential buildings containing a sleeping unit for which a building permit is required; 4) residential units where a fuel burning appliance is added or replaced and for which a permit is required; 5) all existing residential buildings, including single family, duplex, townhome and multifamily.
The following terms as used in this chapter shall have the indicated meaning:
BUILDING CODES: The building and other technical codes adopted pursuant to Title 11 of this code.
CO DETECTOR: A device sensing invisible particles of carbon monoxide that is either battery powered, AC powered with battery backup or connected to a system via an approved control panel that has been installed in accordance with its manufacturer’s recommendations, which, when activated, will provide some form of visual or audible signal, and which has been either UL (Underwriters Laboratories Inc.) listed or CSA (Canadian Standards Association) approved.
DWELLING: Any building or portion thereof containing one or more dwelling units occupied as, or designed or intended for occupancy as, a residence by one or more families.
DWELLING UNIT: Any building or portion thereof designed, occupied, or intended as a `residence, with complete and independent living facilities for one or more persons including permanent provisions for living, sleeping, eating, cooking and sanitation.
RESIDENTIAL OCCUPANCIES:
SEPARATE SLEEPING AREA: Bedrooms or sleeping rooms separated by other use areas, such as a kitchen or living room, but not including bathrooms.
SLEEPING UNIT: A room or space in which people sleep, which can also include permanent provisions for living, eating, and either sanitation or kitchen facilities but not both.
A. All existing residential occupancies and all residential occupancies to be constructed in the future shall be equipped with CO detectors in accordance with the requirements of this chapter.
B. The owner of a residential occupancy shall be responsible to:
C. The owner of a dwelling or dwelling unit that is rented or leased to a tenant, shall:
D. A tenant in possession of a dwelling or dwelling unit shall be responsible for:
A. CO detector(s) shall be centrally located outside of each separate sleeping area in the immediate vicinity of the bedrooms or sleeping rooms and on each level of the residence. Residential occupancies shall be considered to be in compliance with this requirement if CO detector(s) are installed within a dwelling unit such that an audible signal not less than 70 decibels reaches each sleeping area. CO detectors shall be hard wired or connected to a system via an approved control panel in new construction. In interior alterations, repairs or additions requiring a permit, or when one or more sleeping rooms are added or created in existing dwellings, detectors shall be hard wired or connected to a system via an approved control panel where the alterations or repairs result in the removal of interior wall or ceiling finishes unless there is an attic, crawlspace or basement available which would provide access for hard wiring.
B. CO detectors are required in sleeping units containing fuel burning appliances, e.g. gas clothes dryer, decorative gas fireplace, wood burning appliance, etc.
C. It is the intention of this chapter to implement the requirements of the existing building codes, including the latest edition of National Fire Protection Association #720, to the greatest extent practicable for existing residential occupancies. The building official or the fire marshal may approve alternative locations or methods for the installation of CO detectors, if the result would meet the spirit and intent of the building codes and NFPA #720. The building official, in coordination with the fire marshal, may also adopt written guidelines illustrating or describing required locations of CO detectors, and any approved alternative locations or methods for bringing residential occupancies into compliance with the requirements of this chapter.
D. A CO detector is deemed approved for purposes of this chapter if it complies with all applicable state and federal regulations, and bears the label of a nationally recognized standard testing laboratory and meets the revised standard of at least ANSI/UL 2034, Single and Multiple Station Carbon Monoxide Alarms, or ANSI/UL 2075, Gas and Vapor Detectors and Sensors, and subsequent revision or its equivalent. The CO detector may be a combination smoke/gas/CO device.
E. Each CO detector will be mounted in accordance with the manufacturer’s instructions, though ceiling mounting is preferred. CO detector(s) will not be mounted in areas of low air movement (dead air spaces),
F. If a CO detector is required to be installed in a common hallway and found to be tampered with it shall be replaced with a hard-wired device (missing or inoperable batteries shall not constitute tampering) or replaced with a system-connected detector.
G. In new construction, the required CO detector shall receive its primary power from the building wiring when such wiring is served from a commercial source, and when primary power is interrupted, shall receive power from a battery or from an approved control panel. Wiring shall be permanent and without a disconnecting switch other than those required for over current protection. CO detectors shall be permitted to be battery operated when installed in buildings without commercial power or in buildings that undergo alterations, repairs or additions as stipulated in Section 11.38.050 A.
A. It shall be unlawful for any owner of a residential occupancy to fail to install and maintain an operable CO detector when required under the provisions of this chapter.
B. It shall be unlawful for any person to remove or render ineffective a CO detector installed to satisfy the requirements of this ordinance. This provision shall not apply to a building owner, manager or his/her agent in the normal procedure of repairing or replacing a CO detector.
C. No person shall, without privilege to do so, knowingly move, deface, damage, destroy or otherwise improperly tamper with a CO detector required to be installed pursuant to the provisions of this chapter so as to destroy or diminish its effectiveness or availability for its intended purpose.
The building official and the fire code official, or their designees, shall monitor compliance with this chapter and may perform enforcement inspections upon, but not limited to, the following instances: when notified of a change in occupancy; when reviewing or inspecting the construction, repair, rehabilitation or renovation of the interior of a residential occupancy pursuant to a required permit, when inspecting at the request of the building owner or his representative; when inspecting for any other purpose under the provisions of this code; or when on the premises for any lawful purpose, including but not limited to such purposes as responding to a fire or other request for fire department services.
A. Violations, Criminal Enforcement and Penalties
B. Violations, Civil Enforcement.
All owners of residential occupancies shall come into compliance with the requirements of this chapter on or before March 2, 2009. (enacted ord. 03-09)
