A. 
The following provisions shall apply to uses and structures which lawfully existed prior to the adoption of the zoning regulations or any amendment thereof but which do not presently conform to this article:
(1) 
Continuation permitted. Any nonconforming use or structure which lawfully existed at the time of adoption of this chapter or any amendment thereto may be continued upon the lot or in the structure so occupied. Any such nonconforming structure may be restored or repaired in the event of partial destruction thereof, as provided in Subsection A(5) below.
(2) 
Subdivisions involving same. No lot containing a nonconforming use shall be subdivided so as to reduce the lot area of such lot. No lot containing a nonconforming structure shall be subdivided so as to increase the degree or extent of the nonconforming condition.
(3) 
Expansions or alterations. The following provisions shall apply to the expansion or alteration of nonconforming structures or uses:
(a) 
Any nonconforming use or structure which is nonconforming because of use shall not be enlarged, extended or structurally altered in any manner whatsoever.
(b) 
No nonconforming structure may be altered if the alteration would increase the degree or extent of the nonconforming condition or would create any condition on the property that would not be in conformance with this chapter.
(c) 
A nonconforming use or structure changed or altered to a conforming use or structure may not thereafter be changed back to a nonconforming use or structure.
(d) 
A nonconforming use or structure shall not be changed or altered to diminish the nature, degree or extent of the nonconforming condition in one location while simultaneously increasing the nature, degree or extent of the nonconforming condition in another location on the property.
(4) 
Abandonment of nonconforming uses. Notwithstanding the provisions of Subsection A(1) above, in the event that there shall be an abandonment of any nonconforming use, such use shall not be permitted to continue. For purposes of administering this chapter, a nonconforming use shall be presumed to be abandoned if such use shall have ceased to operate for a period of 18 consecutive calendar months, absent showing by the property owner, and a finding by the Zoning Board of Adjustment, that the use has not been abandoned, notwithstanding the cessation of operation.
(5) 
Restoration or repairs. Nothing in this section shall prevent restoration or continuance of a nonconforming building or structure which is partially destroyed by fire, explosion, act of God, or of any public enemy, or the like. "Partial destruction" shall be defined as any destruction of less than 50% of the area or volume, whichever is more restrictive, of the whole building or structure at the time of the partial destruction. If, however, any such building or structure shall be destroyed in excess of 50% of the area or volume of the whole building or structure at the time of such destruction, then after any permitted reconstruction, the same may be used only in such manner as to conform to all the requirements, terms and conditions of this chapter.
B. 
The following provisions shall apply to any lot which lawfully existed at the time of the adoption of the zoning regulations or any amendment thereto but which presently does not conform to the zoning requirements for lot area, lot width, lot frontage, or lot location:
(1) 
Such lots may be used for any use permitted in the district in which it is located, subject to the following requirements:
(a) 
At the time of and since the adoption of the zoning regulation making such lot nonconforming, the owner of the lot shall not have owned any adjoining property, or the lot must be part of a recorded subdivision approved by the Planning Board or the Zoning Board of Adjustment; and
(b) 
All other applicable zoning regulations besides lot area, lot width, lot frontage or lot location must be complied with.
(2) 
Such lots shall not be subdivided so as to increase the degree or extent of any nonconforming lot condition or so as to prevent compliance with this chapter by any reasonable future development on the property.
C. 
The prospective purchaser, prospective mortgagee, or any other person interested in any land upon which a nonconforming use or structure exists may apply in writing for the issuance of a certificate certifying that the use or structure existed before the adoption of the ordinance which rendered the use or structure nonconforming. The applicant shall have the burden of proof. Application pursuant hereto may be made to the administrative officer within one year of the adoption of the ordinance which rendered the use or structure nonconforming or at any time to the Zoning Board of Adjustment. The administrative officer shall be entitled to demand and receive for such certificate issued by him a reasonable fee not in excess of those provided in N.J.S.A. 54:5-14 and 54:5-15. The fees collected by the official shall be paid by him to the municipality. Denial by the administrative officer shall be appealable to the Zoning Board of Adjustment. N.J.S.A. 40:55D-72 to 40:55D-75 shall apply to applications or appeals to the Zoning Board of Adjustment.

(2) 
At least two vertical limit markers shall be set at locations in close proximity to each stockpile area, clearly establishing maximum vertical limits for each stockpile area. The maximum height of stockpiles shall be 20 feet above existing grade in facilities located in areas zoned other than industrial or where the stockpile is within 50 feet of a property line abutting a residential, institutional or public-serving commercial property.
