The use of a building or structure, lot or land, or part thereof, lawfully in existence on February 17, 1987 (the day immediately preceding the effective date of this chapter), or the use of a building or structure, lot or land, or part thereof, lawfully in existence on the day immediately preceding the effective date of any amendment to this chapter affecting such use, and consistently carried on thereafter, which does not conform to the use restrictions presently applicable in the zoning district in which that use is being conducted, may be continued indefinitely, regardless of change of title, possession or occupancy, subject to the following:
A. No nonconforming use shall be enlarged, altered, extended or restored or placed on a different portion of the lot or parcel of land occupied by such use on the effective date of this chapter (or on the effective date of any amendment thereto affecting such use), nor shall any external evidence of such use be increased by any means whatsoever.
B. No nonconforming use shall be moved to another location on a separate lot or parcel where such use would be nonconforming.
C. No nonconforming use shall be changed to another nonconforming use without approval by the Board of Zoning Appeals, and then only by grant of a use variance upon satisfactory proof of eligibility for same.
D. A nonconforming use may be changed to any conforming use and the applicable district bulk regulations and off-street parking requirements shall not apply to such change of use or to alterations made in order to accommodate such conforming use, provided that such alterations do not create any new or additional nonconformity in regard to such regulations or requirements nor increase the degree of any such noncompliance with bulk requirements as may then exist.
E. A nonconforming use that has been changed to a conforming use or been granted a use variance to carry on a different nonconforming use shall immediately and forever lose the limited protection afforded by this section.
F. No nonconforming use shall be reestablished if such use has been abandoned or has been changed to, or replaced by, a conforming use. Intent to resume a nonconforming use shall not confer the right to do so. Discontinuance of a nonconforming use for a period of one year or more shall create a rebuttable presumption of abandonment.
G. Domestic occupancy. The prior use of accessory or principal buildings by servants or employees does not establish use by one or more families.
