A. 
Continuance, alteration, extension. Any lawful single- or two-family building in existence at the time of adoption of this bylaw may continue unchanged, or may be altered and extended in any way which would not result in new or increased violation of any of the dimensional or parking requirements of this bylaw. No other nonconforming building may be altered or extended unless authorized by a special permit acted on by the Board of Appeals upon its finding that such change in structure and in the extent of the associated use will not be substantially more detrimental to the neighborhood than the existing nonconforming structure and use.
[Amended 10-24-2000]
B. 
Reconstruction.
(1) 
A nonconforming building which has been destroyed in part or whole, by catastrophe or otherwise, may be reconstructed as in Subsection A above provided that such reconstruction is begun within six months after destruction and is substantially completed within two years of destruction.
(2) 
Any destroyed portion of a nonconforming building which has not been substantially reconstructed within two years of destruction shall conform to all the dimensional and parking requirements of this bylaw.
C. 
Razing of destroyed or condemned buildings. Any building or other structure which has remained unused after damage and has not been restored to usable condition within five years of damage and any dwelling condemned for habitation and vacant for five years after condemnation shall, within the following year and at the owner's expense, be restored to usable condition or be razed and the site shall be cleared of debris, cellar holes and all other hazards. Owners of any buildings destroyed or condemned prior to the effective date of this bylaw shall have six years from the effective date in which to comply.
A. 
Continuance. Any lawful use in existence at the time of adoption of this bylaw may continue unchanged.
B. 
Change in use. Any change in use or increase in the number of dwelling units shall require an occupancy permit. The most recent nonconforming use which has not been discontinued as defined in Subsection C below may be replaced by another nonconforming use upon granting of a special permit by the Board of Appeals upon its finding that such change in use will not be substantially more detrimental to the neighborhood than the existing nonconforming use.
[Amended 10-24-2000]
C. 
Resumption after discontinuance. Any use replacing a discontinued nonconforming use shall conform to the use and parking regulations of this bylaw. A nonconforming use shall be deemed to have been discontinued if it has been abandoned or not used for a period of two years.
[Amended 10-24-2000]
D. 
Dwellings in nonresidential districts. Any lot in an LI, LI2, EZ, or GI District which was in existence and in separate ownership from all adjoining land on May 3, 1988, and which has a minimum of 5,000 square feet of area and 50 feet of frontage on a way which meets the adequacy requirements referenced in § 220-10B of this bylaw, may be used for one single-family detached dwelling.
[Added 10-24-2000; amended 5-5-2008 ATM by Art. 14; 5-6-2013 ATM by Art. 12; 5-5-2014 ATM by Art. 14]
[Amended 10-24-2000]
A. 
Preexisting lots. The protections afforded under MGL c. 40A, § 6, Subsection 4, to certain preexisting lots for single- and two-family use shall apply in the same manner to lots for nonresidential use.
B. 
Inconsequential change. Existing legally nonconforming lots, whether built upon or not, may be changed in shape or combined, provided that the change does not thereby increase the number of potential building lots, or create or increase a nonconformity, as noted by the Planning Board in reviewing a plan submitted for endorsement that approval under the Subdivision Control Law is not required, or otherwise. Making such change shall not terminate the protection from current requirements provided in MGL c. 40A or in this bylaw.
