N.J. Admin. Code § 7:45-12.8
Government and private projects otherwise subject to review by the Commission for reconstruction or minor alterations may be waived from strict compliance with the Commission's standards if the applicant establishes to the satisfaction of the Commission that the project consists solely of the reconstruction of a previously existing structure that was partially destroyed by fire, flood, or other natural disaster, and that the reconstruction will not increase the use or the exterior dimensions of the structure. For projects within Zone A, reconstruction must not alter the appearance of the structure prior to the natural disaster. Structures that are totally destroyed by such natural disasters are not eligible for waiver.
