N.J. Stat. § 20:4-3.1
A municipality may provide by resolution that where a tenant residing in a structure of two dwelling units or more, is displaced from his dwelling by fire or other emergency, and the damage resulting from the fire or other emergency in the judgment of the housing inspector or other official charged with equivalent responsibility is such as to render the dwelling uninhabitable, the tenant shall be deemed a displaced person under the "Relocation Assistance Act" and shall be eligible for relocation assistance as afforded persons displaced as a result of code enforcement activities. State appropriations of relocation assistance shall not be used for this purpose unless specifically permitted by language in the annual appropriations act.
