Statement of Basis and Purpose of Proposed Rule


On December 30, 2013, Local Law 141 of 2013 was signed by the Mayor.   Among other changes, Local Law 141 amended section 908.7.2 of the New York City Building Code, which requires carbon monoxide (CO) detectors in Group E (educational), I-2 and I-4 occupancies (institutional uses, including hospitals and supervised care facilities). Local Law 141 amended section 908.7.2 to specify where these detectors must be installed.  On April 25, 2014, Local Law 10 of 2014 was signed by the Mayor.  Local Law 10 further amended the New York City Building Code to require that CO detectors be installed in buildings equipped with fire alarm systems that contain Group A-1, A-2, A-3 and certain Group B occupancies (assembly spaces).  These local laws both go into effect on October 1, 2014 but allow the Department to promulgate rules necessary for the implementation of the law prior to the effective date.


This proposed rule sets out the locations within the listed building occupancies where CO detectors must be installed and sets out other requirements related to the installation of CO detectors.


The Department of Buildings’ authority for these rules is found in sections 643 and 1043(a) of the New York City Charter and sections 908.7.2, 908.7.3, and 908.7.4 of the New York City Building Code.
