Nonconforming Lots of Record
A. In any zone in which a one-family dwelling is permitted, a one-family dwelling and customary accessory buildings may be erected on any single lot of record at the effective date of adoption or amendment of this chapter creating the nonconformity, provided:
(1) Such lot was a valid, lawfully existing lot prior to the adoption or amendment of this chapter which created the nonconformity; and
(2) The nonconformity of the lot relates to size or area; and
(3) All other provisions of this chapter, including yard requirements, are complied with, or a variance from such compliance has been obtained from the Board of Appeals.
B. In addition, upon receipt of a special approval from the Board of Appeals, a two-family dwelling may be constructed on such a lot if permitted by the regulations of the zone, subject to the conditions set forth above, and subject to any conditions (such as occupancy or dwelling unit size) that govern two-family dwellings in the zone in which the dwelling is located.
Nonconforming Uses of Land
Where, at the effective date of adoption or amendment of this chapter, a lawful use of land exists that is made no longer permissible under the terms of this chapter as enacted or amended, such use may be continued, so long as it remains otherwise lawful, subject to the following provisions:
A. Such nonconforming use must not be enlarged or increased, nor extended to occupy a greater area of land than was occupied at the effective date of adoption or amendment of this chapter;
B. Such nonconforming use must not be moved in whole or in part to any other portion of the lot or parcel occupied by such use at the effective date of adoption or amendment of this chapter; and
C. If any such nonconforming use of land ceases for any reason for a period of more than one year, any subsequent use of such land must conform to the regulations specified by this chapter for the zone in which such land is located.
Nonconforming Structures
Where a lawful structure exists at the effective date of adoption or amendment of this chapter that could not be built under the terms of this chapter by reason of restrictions on area, lot coverage, height, yards, or other characteristics of the structure or its location on the lot, such structure may be continued so long as it remains otherwise lawful, subject to the following provisions:
A. No such structure may be enlarged or altered in a way which increases its nonconformity.
B. Should such structure be destroyed by any means, in whole or in part, it may be reconstructed in accordance with the provisions of §
270-211 below.
C. Should such structure be moved for any reason for any distance whatever, it must thereafter conform to the regulations for the zone in which it is located after it is moved.
Nonconforming Uses of Structures
If a lawful use of a structure, or of structure and land in combination, exists at the effective date of adoption or amendment of this chapter, that would not be allowed in the zone under the terms of this chapter as amended, the lawful use may be continued as long as it remains otherwise lawful, subject to the following provisions:
A. No existing structure devoted to a use not permitted by this chapter in the zone in which it is located may be enlarged, extended, constructed, moved, or structurally altered except in changing the use of the structure to a use permitted in the zone in which it is located or to a use permitted pursuant to §
270-210 below;
B. 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 such use must not be extended to occupy any land outside such building;
C. Any structure, or structure and land in combination, in or on which a nonconforming use is superseded by a permitted use must thereafter conform to the regulations for the zone in which such structure is located, and the nonconforming use may not thereafter be resumed;
D. When a nonconforming use of a structure, or structure and land in combination, ceases for a period of one year, the structure or structure and land in combination must not thereafter be used except in conformance with the regulations of the zone in which it is located;
E. Where nonconforming use status applies to a structure and land in combination, removal or destruction of the structure eliminates the nonconforming status of the land;
F. Where a nonconforming use exists in an area that has been or now requires site plan approval for any change of use, the nonconforming use may not be changed to any other use permitted in the zone until site plan approval has been obtained pursuant to the terms of this chapter.
Dwellings on Nonconforming Lots
Notwithstanding the provisions above prohibiting enlargement of nonconforming uses, if only a one-family dwelling or a legally existing two-family dwelling and related accessory buildings are present on a lot that is of a size or area less than that otherwise permitted in the zone in which the lot is located, and such lot is a valid nonconforming lot, such dwelling may be enlarged or altered provided:
A. The existing dwelling is in conformance with all requirements of this chapter except for the fact that it is located on a lot that is less than the required size or area which lot was of record at the time of the adoption or amendment of this chapter creating the nonconformity;
B. Such alteration or enlargement does not violate any other provisions of this chapter (e.g., yard, height, or other restrictions); and
C. If such dwelling is a single-family dwelling, upon completion of such enlargement or alteration the building and lot continue to be used only as a single-family dwelling, provided, however, that upon receipt of a special approval from the Board of Appeals, a single-family dwelling may be enlarged to a two-family dwelling, subject to the conditions set forth above, and subject to any conditions (such as occupancy or dwelling unit size) that govern two-family dwellings in the zone in which the dwelling is located.
