Analysis: Review of proposed new standards NFPA 720-2009 and UL 2034-2008 indicated that, in the opinion of ICC Staff, the standards did comply with ICC standards criteria.
Modify proposal as follows:

The carbon monoxide detectors shall be listed as complying with UL 2075.

R2 occupancies not already equipped with a carbon monoxide alarm shall be provided with a carbon monoxide alarm when alterations, repairs or additions requiring a permit occur. Or one or more sleeping rooms are added or created. The carbon monoxide alarms shall be listed as complying with UL 2034 and be installed and maintained in accordance with NFPA 720 and the manufacturer’s instructions.
Exception: Sleeping units or dwelling units in R-1 occupancies and R-2 college dormitories, hotel, and DSHS licensed boarding home and residential treatment facility occupancies which do not themselves contain a fuel-burning appliance or fuel burning fire place or have an attached garage, but which are located in a building with a fuel-burning appliance or an attached garage, need not be provided with single station carbon monoxide alarms provided that:

(Portions of the proposal not shown remain unchanged.)
Committee Reason: The committee approved the proposal adding CO detectors to the code since having provisions within the IBC and IFC is a better approach than what has been occurring on a state level through the legislative process. This also makes the IBC and IFC consistent with the IRC. The first modification clarifies that ventilated enclosed parking garages were not intended to be considered as an attached garage for the purposes of enforcing this section. The second modification includes the use of CO detectors and associated systems in accordance with UL 2075. Such detectors are allowed by NFPA 720 and the committee felt it was appropriate to recognize both CO alarms and detectors.
