Any structure or use which was legal when built
or commenced and which was in existence at the time of enactment or
amendment of this chapter, which becomes nonconforming as a result
of such enactment or amendment, may be continued, except that:
A. A sign which is nonconforming under this chapter or
under any previous ordinance or local law shall be subject to the
provisions of § 145-39D(6).
B. Outdoor storage areas shall be required to comply with §
145-51.
A nonconforming use or structure shall not be
extended, enlarged, or structurally altered except as provided below.
The extension of a conforming use to any portion of a nonconforming
structure shall not be deemed the extension of a nonconforming structure
or use.
A. A nonconforming structure or use may be rebuilt in
the event of its total or partial destruction, to occupy the same
or a lesser amount of footprint, but may not exceed the original height
of the totally or partially destroyed structure. Such rebuilding shall
require site plan review by the Planning Board.
B. The Planning Board may issue a special permit allowing an expansion of a nonconforming use or structure by up to 50% of its area at the time of the adoption of this chapter, provided that all other requirements can be met, and that such expansion does not reduce any nonconforming setbacks by more than 20%. Expansion or introduction of uses prohibited by §
145-10C shall not be permitted.
C. A nonconforming soil mining operation may expand by
mining within the boundaries of the original parcel on which the mine
was legally permitted only to the extent allowed by an existing Department
of Environmental Conservation (DEC) permit or as otherwise provided
by the laws of New York State. A soil mining operation commenced in
violation of the Dover Zoning Law after September 1, 1991, shall be
permitted to continue mining under a valid DEC permit but shall not
be permitted to expand or otherwise benefit from the legal protections
afforded under state law for a nonconforming use that was commenced
in full compliance with applicable local laws and regulations. Such
an operation may not process materials mined off site by crushing,
screening, sorting, washing, drying, or otherwise. This shall not
prevent the continuation of any nonconforming industrial use of a
property where soil mining products mined off site are used as a raw
material.
D. A nonconforming use or structure may be repaired or
restored to a safe condition.
A nonconforming use of a structure or parcel of land may, upon issuance of a special permit by the Planning Board, be changed to another nonconforming use which is of the same or lesser impact, except that no use prohibited by §
145-10C shall be permitted under any circumstances. No structure in which a nonconforming use has been changed to a use of lesser impact shall again be devoted to a nonconforming use with greater impact. In determining whether a use is of greater or lesser impact, the Planning Board shall consider the impact criteria listed in §
145-63.
Any preexisting legal use which is allowable
by special permit under this chapter, but which has not been issued
a special permit, shall be considered a nonconforming use until it
is granted a special permit by the Planning Board. The expansion of
such a use, other than a single-family or two-family residence, shall
require site plan approval.
Any structure for which construction was begun prior to the effective date of this chapter, or of any amendment thereto, may be completed and used in accordance with the approved plans and specifications for such structure. Any structure for which construction has not begun pursuant to approved plans shall be subject to the provisions of this chapter and any amendments thereto, even if all preconstruction approvals have been granted. For purposes of this §
145-28, "beginning construction" shall mean excavation and pouring of footings or the installation of any other means of permanently attaching a structure to the ground.
