A nonconforming structure may continue so long as it remains otherwise lawful, subject to the following:
A nonconforming structure may be enlarged or altered as long as the enlargement or alteration will not increase its nonconformity.
In the event any nonconforming building is destroyed by an act of God or any other cause not within the control of the owner, the owner may rebuild the destroyed building or one designated for the same use and may use the building for such use regardless of whether the provisions of this chapter may otherwise prohibit the construction of such a building or prohibit such a use in a district in which the land is located; provided, however, that the rebuilding of such structure shall commence not more than two years from the date of the event which caused the loss of the original structure, and provided further that the use of said rebuilt structure shall commence within one year from the completion of said building as provided for herein.
Should any nonconforming structure be moved for any reason, for any distance whatsoever, it shall thereafter conform to the regulations for the district in which it is located after it is moved.
If a lawful use of a structure and premises in combination exists on the effective date of adoption or amendment to this chapter that would not be allowed in the district under the terms of this chapter or chapter amendment, the lawful use may be continued so long as it remains otherwise lawful, subject to the following:
No existing structure devoted to a use not permitted by this chapter in the district in which it is located shall be enlarged, extended vertically or horizontally or moved, except in changing the use of the structure to a use permitted in the district in which it is located, except as otherwise provided for herein or except as may be accomplished or provided for under the variance procedure as set forth herein.
Any nonconforming use may be extended throughout any parts of a building which were manifestly arranged or designed for such use at the time of adoption or amendment of this chapter, but no such use shall be extended to occupy any land outside such building.
Any structure or structure and land in combination in or on which a nonconforming use is superseded by a permitted use shall thereafter conform to the regulations for the district in which such structure is located, and the nonconforming use may not thereafter be resumed.
When a nonconforming use of a structure or structure and premises in combination is discontinued or abandoned, for any other reason, for 12 consecutive months or for 18 months during any three-year period, such nonconforming use shall cease, and the structure or structure and premises in combination shall not thereafter be used except in conformance with the regulations of the district in which it is located.
All nonconforming uses existing at the time of the effective date of this chapter amendment may be registered by the Zoning Officer. Certificates of occupancy shall be issued to all nonconforming uses by the Zoning Officer. Any person, partnership, corporation or legal entity with an ownership interest in a nonconforming lot, structure, use or combination of nonconforming characteristics may also register such nonconformity with the Zoning Officer, provided verification of the nonconformity is provided.
Nothing in the zoning district regulations shall be held to prohibit the erection of a single-family dwelling in a zoning district upon a lot whose size is inadequate to meet the lot area regulations set for the district, provided that such lot on the effective date of this chapter is held under separate ownership from the lots adjoining thereto, has the right of direct access to a public street, and its use complies with all other applicable zoning district regulations.
