New Jersey Statutes Title 2A. Administration of Civil and Criminal Justice 2A § 42-88

a. The public officer or any tenant occupying a dwelling may maintain a proceeding as provided in this act, upon the grounds that there exists in such dwellings or in housing space thereof a lack of heat or of running water or of light or of electricity or of adequate sewage disposal facilities, or any other condition or conditions in substantial violation of the standards of fitness for human habitation established under the State or local housing or health codes or regulations or any other condition dangerous to life, health or safety.

b. A public officer, a tenant whose utility service has been diverted or a utility company providing electric, gas or water utility service to a dwelling may maintain a proceeding as provided in this act upon the grounds (1) that there exists in these dwellings or in housing space thereof a wrongful diversion of electric, gas or water utility service by the owner or owners or other party from a tenant of the dwelling without the consent of the tenant, or the use by the owner or other party in the dwelling without the tenant's consent of electric, gas or water utility service that is being charged to the tenant, and (2) that the owner has been notified by either a public officer, a tenant whose utility service has been diverted or a utility company of the wrongful diversion or unconsented use by certified mail and has failed to take necessary action to correct or eliminate the wrongful diversion or unconsented use within 30 days of receipt of such notice. If an owner fails or refuses to accept a notice sent by certified mail, the date of receipt shall be deemed to be the third day after mailing, provided the notice was sent to the owner at an address to which the owner's utility bills or municipal tax bills are sent.
