A.
Continuance.
(1)
Any lawful nonconforming use on a lot which existed on the date of adoption of this chapter may be continued.
(2)
Any existing structure designed, arranged, intended or devoted to a nonconforming use may be structurally altered subject to the following regulations:
(a)
A nonconforming use shall not be enlarged unless the use is changed to a conforming use; provided, however, that where a building meets the use requirements of this chapter and is nonconforming because of height, area and/or yard regulations, said use may be enlarged, provided that height, area or yard regulations are not further violated, and further provided that in the case of a building which is located in violation of a side or rear yard regulation, any expansion thereof within the same plane of the wall which is in violation of said yard regulations shall be considered a further violation and shall require granting variance therefor, prior to such expansion.
(b)
A nonconforming use changed to a conforming use shall not thereafter be changed back to a nonconforming use.
(c)
A nonconforming use in existence at the time of adoption of this chapter shall not be permitted to be changed to another nonconforming use unless such change would reduce the degree of nonconformance.
(d)
If any nonconforming use shall terminate or cease its activity for a continuous period of not less than two years, it shall not be reestablished but shall be replaced with a use in full conformity with the provisions of this chapter, except that the Board of Adjustment may permit such nonconforming use to be reestablished only to the extent that it existed upon passage of this chapter if it shall find, upon petition therefor and presentation of adequate factual evidence, that such peculiar circumstances exist, whether it is in the form of structural improvements, formation or character of the lot and lands, that no other use in closer conformity to the standards of this chapter may be established thereon.
(e)
Any existing lot which is nonconforming may be modified, provided that when a new lot is formed so as to include within its boundaries any part of a former lot on which there is an existing building or use, the subdivision must be carried out in such a manner as will not infringe upon any of the provisions of this chapter, either with respect to any existing structures or use or any proposed structures or use.
(f)
A zoning permit may only be issued for a nonconforming use or structure after application to the Zoning Board of Adjustment and a hearing on the same, upon notice to all parties entitled thereto.
B.
Completion of existing buildings. Nothing in this chapter shall require any change in plans, construction or designated use of a structure for which a building permit has been issued when construction has been diligently prosecuted within six months following the date of such permit and completed within the term of such permit.
C.
Termination of existing nonconforming uses. If the owner of property upon which a nonconforming use exists wishes to terminate such use and replace it with a use of less objectionable or obnoxious character or with a use in closer conformity with the standards established in the zone for health, safety and neighborhood character, he may do so upon appeal to the Zoning Board and upon finding thereto upon submittal of appropriate factual evidence. The Zoning Board, in granting such appeal, shall impose such conditions as shall ensure adequate limitations upon the extent of such use and the design or alteration of any structure to these ends.
D.
Unlawful use not authorized. Nothing in this chapter shall be interpreted as implied authorization for or approval of the continuance of the use of a structure premises in violation of zoning regulations in effect at the time of adoption of this chapter.
E.
Nonconforming structures, land or uses due to reclassification. The foregoing provisions of this article shall also apply to structures, land or uses which hereafter become nonconforming due to any reclassification of zones under this chapter or any subsequent change in the regulations of this chapter.
