13-64-200 Carbon monoxide detectors – Exemptions.

   The following dwelling units shall not require carbon monoxide detectors:

   (a)   A dwelling unit in a building that (1) does not rely on combustion of fossil fuel for heat, ventilation, cooking, or hot water, (2) does not contain a fossil fuel burning fireplace, and (3) is not sufficiently close to any ventilated source of carbon monoxide, as determined by the building commissioner, to receive carbon monoxide from that source.

   (b)   A dwelling unit that (1) is heated by steam, hot water or electric heat, (2) does not contain a fossil fuel burning fireplace, (3) is not connected by ductwork or ventilation shafts to any room containing a fossil fuel- burning boiler or heater, and (4) is not sufficiently close to any ventilated source of carbon monoxide, as determined by the building commissioner, to receive carbon monoxide from that source.

   (c)   Notwithstanding the foregoing, a residential unit that is in any way connected to a garage shall not be exempt under this section unless the building commissioner has determined that the residential unit is not sufficiently close to any ventilated source of carbon monoxide to receive carbon monoxide from that source.

      (3)   Carbon monoxide detection systems. Carbon monoxide detection systems shall be an acceptable alternative to carbon monoxide alarms and shall comply with the following:

         (A)   General. Carbon monoxide detection systems shall comply with NFPA 720-15. Carbon monoxide detectors shall be listed in accordance with UL 2075.

         (B)   Locations. Carbon monoxide detectors shall be installed in the locations specified in Section 13-64-210. These locations supersede the locations specified in NFPA 720.

         (C)   Combination detectors. Combination carbon monoxide/smoke detectors installed in carbon monoxide detection systems shall be an acceptable alternative to carbon monoxide detectors, provided they are listed in accordance with UL 2075 and UL 268.
