[Amended 10-25-1999 STM, by Art. S4]
A.
Applicability.
(1)
No provision of this Zoning Bylaw shall apply to structures or uses lawfully in existence or lawfully begun, or to a building or special permit issued before the first publication of notice of the public hearing required by MGL c. 40A, § 5. Such prior, lawfully existing nonconforming uses and structures may continue, provided that no modification of the use or structure is accomplished, unless authorized hereunder.
(2)
If real property has been improved by the erection or alteration of one or more structures and the structures or alterations have been in existence for a period of at least 10 years and no notice of action, suit or proceeding as to an alleged violation of this chapter or of a bylaw adopted under this chapter has been recorded in the Registry of Deed for the county or district in which the real estate is located or, in the case of registered land, has been filed in the registry district in which the land is located within a period of 10 years from the date the structures were erected, then the structures shall be deemed, for zoning purposes, to be legally nonconforming structures subject to MGL c. 40A, § 6, and any local bylaw related to nonconforming structures.
B.
Nonconforming uses. The Board of Appeals shall award a special permit to change a nonconforming use in accordance with this section only if it determines that such change or extension may not be substantially more detrimental than the existing nonconforming use to the neighborhood. The following types of changes to nonconforming uses may be considered by the Board of Appeals:
C.
Nonconforming structures. The Board of Appeals may award a special permit to reconstruct, extend, alter or change a nonconforming structure in accordance with this section only if it determines that such reconstruction, extension, alteration, or change shall not be substantially more detrimental than the existing nonconforming structure to the neighborhood. The following types of changes to nonconforming structures may be considered by the Board of Appeals:
D.
Variance required. Except as provided below in Subsection E, the reconstruction, extension or structural change of a nonconforming structure in such a manner as to increase an existing nonconformity, or create a new nonconformity, including the extension of an exterior wall at or along the same nonconforming distance within a required yard, shall require the issuance of a variance by the Board of Appeals.
E.
Nonconforming single- and two-family structures.
(1)
Nonconforming single- and two-family residential structures may be reconstructed, extended, altered or structurally changed upon a determination by the Building Commissioner that such proposed reconstruction, extension, alteration, or change does not increase the nonconforming nature of said structure. The following types of changes shall be deemed not to increase the nonconforming nature of said structure; provided, however, that in no case shall the alteration to the nonconforming structure result in (a) a structure no more than the lesser of the maximum height allowable under these bylaws, or a ten-percent increase in existing height, or (b) a structure closer to the side or rear lot lines than 10 feet in Residence A, 15 feet in Residence B, 20 feet in Residence C or 20 feet in Residence D; said residential districts as shown on the Zoning Map of the Town of Marion, Massachusetts, February, 1984, final revision date July, 1999:
(a)
Alteration to a structure located on a lot with insufficient area, where such alteration complies with all current setback, yard, building coverage, and building height requirements.
(b)
Alteration to a structure located on a lot with insufficient frontage, where such alteration complies with all current setback, yard, building coverage, and building height requirements.
(c)
Alteration to a structure encroaching upon one or more required yard or setback areas, where such alteration will comply with all current setback, yard, building coverage and building height requirements.
(2)
In any other case, the Building Commissioner shall refer the matter to the Board of Appeals. The Board of Appeals may, by special permit, allow such reconstruction, extension, alteration, or change where it determines that the proposed modification will not be substantially more detrimental than the existing nonconforming structure to the neighborhood.
[Amended 4-29-2003 STM by Art. S2]
F.
Abandonment or non-use. A nonconforming use or structure which has been abandoned, or not used for a period of two years, shall lose its protected status and be subject to all of the provisions of this Zoning Bylaw.
G.
Catastrophe or demolition. Any nonconforming structure may be reconstructed after a fire, explosion or other catastrophe or after demolition, provided that such reconstruction is completed within 24 months after such catastrophe or demolition caused by a catastrophic event, and provided that the building(s) as reconstructed shall be located on the footprint of the nonconforming structure and rebuilt to an extent only as great in volume or area as the original nonconforming structure unless a larger volume or area or different footprint is authorized by special permit from the Board of Appeals. The Board of Appeals may extend by 12 months the period of completion.
[Amended 10-15-2001 STM by Art. S11]
