A. 
Except as otherwise provided in this chapter, the lawful use of the land or a building existing at the date of the adoption of this chapter may be continued although such use or building does not conform to the regulations specified by this chapter for the zone in which such land or building is located; provided, however, that:
(1) 
No nonconforming lot shall be further reduced in size.
(2) 
No nonconforming building shall be enlarged, extended or increased unless such enlargement is conforming.
(3) 
No nonconforming use may be expanded.
A nonconforming use shall be presumed to be abandoned when there occurs a cessation of such use or activity by an apparent act or failure on the part of the tenant or owner to reinstate such use within a period of one year from the date of cessation or discontinuance. Such use shall not thereafter be reinstated and the structure shall not be reoccupied, except in conformance with this chapter.
If any nonconforming building shall be destroyed by reasons of windstorm, fire, explosion, act of God, or otherwise, to an extent of more than partial destruction as provided for in N.J.S.A. 40:55D-68, then such destruction shall be deemed complete destruction, and the structure may not be rebuilt, restored or repaired, except in conformity with the regulations of this chapter. Nothing in this chapter shall prevent the strengthening or restoring to a safe condition of any wall, floor or roof which has been declared unsafe by the Construction Official.
No nonconforming use shall, if once changed into a conforming use, be changed back again into a nonconforming use.
A nonconforming building may be altered, but not enlarged or extended, during its life to an extent not exceeding the aggregate 50% of the assessed value, as recorded in the records of the Tax Assessor, unless said building is changed to a building conforming to the requirements of this chapter.
Nothing herein contained shall require any change in the plans, construction or designated use of a building for which a building permit has been heretofore issued and substantial construction has taken place prior to the date of the adoption of this chapter.
Whenever the boundaries of a district shall be changed so as to transfer an area from one district to another of a different classification, the provisions of this chapter shall also apply to any nonconforming uses existing therein or created thereby.

In the case of a detached single-family dwelling and a lot in the R-1A, R-3A and R-5A zones, which were conforming on December 29, 2002, said detached single-family dwelling may be enlarged or extended provided: 1) The proposed addition, enlargement, or extension complies with all of the regulations of the zone district in which the structure was situated on December 29, 2002; or 2) At the time of and since the adoption of Ord. No. 02-46 on December 30, 2002, which rendered the lot nonconforming, either the owner of the lot does not and did not own adjoining property, which would otherwise render the property more conforming or conforming, or the owner of such property has consolidated by deed, or does agree to consolidate by deed, the adjoining land owned in common to render the property more conforming or conforming to the current zoning requirements.
[Amended 6-26-2003 by Ord. No. 2003-10]
A single construction permit permitting the construction of one detached single-family dwelling may be issued for any parcel of land in the R-1A, R-3A and R-5A Residential Zones with an area less than required for a lot in the zone in which the lot is located provided: 1) The proposed single-family detached dwelling and lot comply with all the zoning requirements of the zone district in which the lot was located on December 29, 2002; or 2) At the time of and since the adoption of Ord. No. 02-46 on December 30, 2002, which rendered the lot nonconforming, the owner of the lot does not and did not own a contiguous lot (or lots), not qualifying under this section, in and of itself, which would otherwise render the property more conforming or conforming. The owner of such non-qualifying property shall consolidate by deed, or shall agree to consolidate by deed, the adjoining lot (or lots) to render the property more conforming or conforming to the current zoning requirements.
Notwithstanding the above, the provisions of this section will expire on December 31, 2003. This expiration provision shall not be construed to affect any parcel with rights conferred pursuant to a valid building permit or approval granted by the Planning Board of Zoning Board of Adjustment.
[Amended 9-11-2003 by Ord. No. 2003-22]
Notwithstanding an existing nonconforming front yard setback of a non-residential structure fronting on Route 9 in the General Business (GB) Zone, such structure may be enlarged or extended within the required front yard setback area provided that: such enlargement does not extend beyond the existing non-conforming front yard setback; does not enlarge or extend the structure into any other required side or rear yard, which is now conforming; and the current or proposed use of the structure is a permitted use within the GB Zone. The proposed enlargement or extension, which would otherwise be non-conforming except as otherwise permitted pursuant to this subsection, may not exceed 1,000 square feet in total floor area.
