A.
Continuance. The lawful use of any structure or land existing at the time of the enactment or subsequent amendment of this chapter may be continued although such structure or use does not conform with the provisions of this chapter, subject to the following conditions and exceptions.
B.
Restoration or reconstruction.
(1)
In the event that a nonconforming building is destroyed by fire, explosion or other natural cause, or is in a state of disrepair and dilapidated, the same may be reconstructed or repaired on the same location for the same use or a conforming use, provided the new building is at least equal in appearance and character to the original structure.
(2)
Restoration or reconstruction due to fire, explosion or other natural cause, must be undertaken within one year of the date damage is inflicted unless, upon application to the Board of Appeals, the owner can show that restoration within the time limit is impracticable, in which case extension of time may be granted.
C.
Change, extension or alteration.
(1)
As provided in MGL c. 40A, § 6, a nonconforming single- or two-family dwelling may be altered or extended provided that the Inspector of Buildings determines that doing so does not increase the nonconforming nature of said structure. Other preexisting nonconforming structures or uses may be extended, altered, or changed in use on special permit from the Board of Appeals if the Board of Appeals finds that such extension, alteration, or change will not be substantially more detrimental to the neighborhood than the existing nonconforming use.
(2)
Once changed to a conforming use, no structure or land shall be permitted to revert to a nonconforming use.
D.
Abandonment. A nonconforming use which has been abandoned for a period of two years shall not be reestablished and any future use shall conform with this chapter, except in the case of land used for agriculture, horticulture, or floriculture where such non-use shall have existed for a period of five consecutive years.
E.
Reuse of nonconforming structures. A building or structure which is nonconforming in that such building or structure does not conform to setback, height, or other dimensional requirements may be reused for any other use permitted by right or by special permit in that zoning district without the need to conform to such dimensional requirements provided that the Inspector of Buildings determines that the new use meets all the requirements of the Zoning Ordinance and that any changes or alterations to the structure do not increase the nonconforming nature of the structure or result in a new nonconformity with the existing requirements of the district; and provided further that the Zoning Board of Appeals or designated special permit granting authority issues a special permit for uses requiring a special permit.
