The lawful use of any structure of land existing at the time of enactment or subsequent amendment of this bylaw may be continued although such structure or use does not conform with provisions of the bylaw, subject to the following conditions: [Note: MGL c. 40A, § 6 attached (last few pages).[1]]
A.
Alteration or extension. No addition to or increase in the extent of a nonconforming use of a structure or land may be made, except that the Zoning Board of Appeals may grant a special permit for expansion of existing campgrounds, mobile home parks, motels or motor courts, and cottage colonies using only those parcels employed at the time the use was made nonconforming.
B.
Restoration. In case of destruction or damage by fire or other catastrophe, a legally nonconforming structure may be rebuilt in substantially the form it had at the time of the destruction or damage, or in any form if within applicable setback requirements in accordance with existing building code requirements, and not larger than previously (provided that reconstruction is started within 12 months and completed within 24 months of the catastrophe).
C.
Changes. A nonconforming use may be changed to a more nearly conforming use; and once changed to a more nearly conforming or conforming use, no structure or land shall be permitted to revert to a less conforming use.
D.
Discontinuance or abandonment. A nonconforming use, which has been abandoned, shall not be reestablished. Any nonconforming use discontinued for a period of two years or more shall not be reestablished, and any future use shall conform with this bylaw, unless reestablishment is authorized by special permit from the Zoning Board of Appeals, upon its determination that the discontinuation occurred despite good faith efforts of the owner to reestablish the use within two years, and that reasonable efforts will be made to mitigate any harmful impact upon the vicinity.

E.
Alterations to nonconforming single- or two-family residential structures.
(1)
Nonconforming single- or two-family residential structures may be altered if:
(a)
The Building Inspector determines that the alteration will not increase the nonconforming nature of the structure; or
(b)
If the alteration will increase the nonconforming nature of the structure, the Zoning Board of Appeals issues a special permit after determining that the alteration is not substantially more detrimental to the neighborhood than the existing nonconforming structure.
(2)
Conforming single- and two-family residential structures located on nonconforming lots may be altered if:
(a)
The structure after the alteration will continue to conform; or
(b)
If the structure after the alteration will not continue to conform, the Zoning Board of Appeals issues a special permit after determining the alteration is not substantially more detrimental to the neighborhood than the existing nonconforming use.
(3)
Permits issued under Subsection E(1)(b) and E(2)(b) of this section shall be subject to the provisions of § 235-8.4B(4) and § 235-8.4C(5) of this bylaw. In making the determination to issue the permit, the Zoning Board of Appeals may consider other criteria in § 235-8.4B.
