Carbon Monoxide Detector Affidavits

Q: I am processing Certificate of Occupancy issuance for a building, and have been asked to provide a Carbon Monoxide Detector Affidavit by DOB. When is this required by Code? What is the Law for Carbon Monoxide Detectors? Where can I find more information?

A: Carbon Monoxide Detectors are now required in certain Occupancy Groups per Local Law 7/2004. They are required in J-3 (Single- and Two-Family Residences), J-2 (Multiple Dwellings), J-1 (Hotels), G (Educational/School), and H-2 (Hospitals) Occupancies.

For Residential buildings, a CO Detector is required within 15' of the entrance to Sleeping Rooms, and also in the vicinity of Fossil-Fuel Burning Equipment (such as in a Boiler Room, Parking Garage, Laundry Room with Gas Dryers).

For G and H-2, at least one CO Detector shall be installed in the vicinity of Fossil-Fuel Burning Equipment.

An Affidavit for the installation of CO Detectors will be requested by the Construction Division at the time of TCO/CO issuance or TCO Renewal (unless already on file).
