N.J. Stat. § 5:3-48
If there are practical difficulties or unnecessary hardships for an owner to comply with any rules and regulations adopted pursuant to this act, or if an owner is aggrieved by any order issued thereto, the department may modify the application of such rules, regulations or order in the spirit of the provisions of this act with regard to public safety. Any owner may, within 10 days after the promulgation of such rules or regulations or the service of such order, apply to the department for a modification of said rules, regulations or order. The request shall be in writing and shall state the grounds for applying for such modification. It shall be the duty of the department to provide such hearing at the earliest convenient opportunity, at which time the owner shall have the right to be heard personally or by counsel, to cross-examine witnesses appearing against him and to produce evidence in his own behalf. After such hearing the department shall report in writing its findings and recommendations, which shall include a description of the conditions under which the modifications, if any, are permitted. Such hearing and decision shall conform to the applicable provisions of the "Administrative Procedure Act," and a record of all authorized modifications shall be kept by the department and open to the public.
