New Jersey Statutes Title 26. Health and Vital Statistics 26 § 3-31.5

The governing body of any municipality may provide, by ordinance, that the local health officer or other officer designated in the ordinance shall, whenever necessary to protect the health and safety of residential tenants, act as an agent for a landlord in engaging a fuel oil dealer to deliver fuel oil at a reasonable price per gallon and to refire the burner to restore the proper heating of any residential property rented by said landlord; provided, however, that at least 12 hours have elapsed, if the outside air temperature is between 33° and 55° F., inclusive, or at least 4 hours have elapsed, if the outside air temperature is 32° F. or less, since the tenant has lodged a complaint with any municipal officer or agency, prior to which complaint a bona fide attempt has been made by the tenant or his representative to notify the landlord of the lack of heat, and the landlord has failed to take appropriate action. Lack of heat means maintaining less heat than required by R.S. 26:3-31.
