Any lawful nonconforming use of buildings or open land in existence on the effective date of this chapter may be continued indefinitely if maintained in accordance with all applicable codes, ordinances, regulations and other requirements, but shall not be expanded, extended, moved, changed or reestablished except as specifically provided in this article:
(1) A nonconforming use may be expanded within an existing structure or on an existing site, provided that the extent of such expansion, whether occurring as a single expansion or as the aggregate of two or more smaller expansions, does not exceed 50% of the gross floor area of the structure or land area of the portion of the site dedicated to the nonconforming use at the time of enactment of this chapter. Any such expansion shall be preceded by site plan review and approval by the Planning Board in accordance with Article
VII of this chapter.
(2) An existing building housing a nonconforming use may be extended and thereafter occupied by the nonconforming use, provided that the extent of such addition, whether occurring as a single addition or as the aggregate of two or more smaller additions, does not exceed 50% of the gross floor area of the existing building and the addition is in strict compliance with the requirements set forth for the zoning district in the District Schedule of Area and Bulk Regulations. Any such extension shall be preceded by site plan review and approval by the Planning Board in accordance with Article
VII of this chapter.
(3) Nothing contained herein shall be deemed to prevent the restoration of a lawful nonconforming use after damage for any reason or by any cause, provided that the replacement facility shall not have a greater floor area or be able to accommodate a greater number of patrons or customers than the facility which existed prior to the damage, that all applicable provisions of the New York State Uniform Fire Prevention and Building Code are strictly met, and that the restoration is commenced within 12 calendar months of the damage and is fully completed within two calendar years of such occurrence. The issuance of a building permit for any such restoration shall be preceded by site plan review and approval by the Planning Board in accordance with Article
VII of this chapter.
