New York law requires that a functioning carbon monoxide and smoke detector be installed in every one or two-family dwelling, co-op or condo constructed or offered for sale. Additional rules apply regarding location and type.
Carbon monoxide detector rules are covered in section 5-a and apply when there is a carbon monoxide source in the home.
Smoke detector rules are covered in section 5-b.
An affidavit of compliance is required. Title companies and attorneys have template affidavits used prior to a closing to comply with these laws. An affidavit furnished by an association (HGAR) can also be found here:
