3.3.2.5 Two-thirds (2/3) of the total land area of every building lot must be free from
wetlands as defined in Massachusetts Wetland Protection Act as most recently revised
and other conditions which make building impossible or hazardous. However, where a
building lot contains a contiguous upland area equal to two-thirds (2/3) of the minimum
lot size required in that district, the lot shall be exempt from the provisions of this
section. No such lot shall be further subdivided so that the contiguous upland area is
reduced to less than two-thirds (2/3) of the minimum lot size required by this section.
3.3.2.6 In districts where accessory apartments are permitted, no dwelling unit shall
contain more than one (1) accessory apartment.

front, rear and side lot lines.

access utility service, and drainage serving each structure shall be functionally equivalent
to that required for separate lots in the Planning Board's adopted Subdivision
Regulations; the minimum lot area, width, and frontage shall be the sum of the
requirements for each structure; and the minimum distance between such structure shall
be the height of the higher building.
3.3.3.2 Where no street line has been established or can be readily determined, such line
shall be assumed to be thirty (30) feet from the center of the traveled roadway for the
purpose of applying these regulations.
3.3.3.3 Projections of not more than three (3) feet are permitted in required yards for
architectural features of a building, such as stairs, chimneys, cornices, eaves or canopies,
but not for bay windows or other enclosed habitable projections.

equal to the front yard setback requirement in the district.
