In all districts, after the effective date of this chapter, any existing building or other structure or any tract of land or use which is not in conformity with the regulations for the district in which it is located shall be deemed legally nonconforming and may continue subject to the appropriate regulations of this chapter governing such nonconforming uses, lots and structures. A nonconforming structure, which is destroyed by casualty, may be rebuilt to the same dimensions and height, and on the same footprint, as the nonconforming structure, provided that construction is started within one year of the date of destruction. A nonconforming use or structure shall not be expanded without a variance approval from the Zoning Board, except that an existing nonconforming single-family residence structure may be expanded without a variance, provided that the expansion does not increase the nonconformity in any manner. All construction shall be according to the New Jersey building and construction codes.

Where two or more adjoining lots are under the same ownership and one or more of said lots should not conform with the minimum area or dimension requirements for the zone in which it is located, the lots shall be considered as a single lot and the provisions of the following subsection shall not apply.

Any nonconforming lot existing on the effective date of this chapter which does not meet the definition of the previous subsection may have a building permit issued for a permitted use without an appeal to the Board of Adjustment, provided that the building coverage is not exceeded and the parking and yard requirements are met.
