Lot Area. No structure other than a solar energy system may be erected on any lot that does not have at least the minimum lot area set forth in Table 2 for the district in which the lot is located.

Developable Site Area. No dwelling may be erected on any lot that does not contain a contiguous developable site area that is at least 90% of the minimum lot area for the district in which the lot is located.

Minimum Lot Frontage Required. No structure other than a solar energy system may be erected on any lot that does not have at least the minimum frontage set forth in Table 2[1] for the district in which the lot is located on a street. Frontage on unaccepted ways in existence prior to the adoption of the Subdivision Control Law must receive a favorable determination from the Planning Board. Ways laid out, but not constructed, may not be used as frontage.

Designation of Frontage Street. When a lot is bounded by more than one street, any one of them, but only one, must be designated as the frontage street, provided the street meets the requirements for minimum lot frontage described in this bylaw. In the case of a lot bounded by two streets forming an interior angle of more than 135°, their combined frontage may be used to satisfy the lot frontage requirement.

Measurement of Lot Frontage. Frontage is measured in a continuous line along the sideline of the street right-of-way between the points of intersection of the side lot lines with the street right-of-way line. The measurement of lot frontage excludes jogs in the street width, backup strips and other irregularities in the street line. In the case of a corner lot, the owner may extend to the midpoint of the curve connecting street lines, instead of to their intersection.

Access. An owner must provide a means of access for vehicles from the frontage street to a principal building for emergency services, for deliveries, and for off-street parking. Alternatively, the owner may provide the access from another street provided it can be demonstrated that it is both physically and legally possible to provide access from the designated frontage street.

Frontage Reduction on Curves. Where more than half of the lot frontage is on a circular turnaround, or on a curve of less than one-hundred-foot radius, frontage may be reduced to not less than 60% of the distance required in Table 2 if the distance between the side lot lines, measured along the arc parallel to the street line at the same distance from the street line as the front yard setback required by Table 2, is not less than the minimum lot frontage required by Table 2.

Frontage on Turnaround in CRO Districts. In CRO Districts where a lot abuts on a dead-end turnaround part of a street and also abuts on such street before the turnaround, the frontage may be measured in part along the street line before the turnaround and in part along a projection of the course of such street line through and beyond the turnaround, provided that the lot has frontage of not less than 60 feet on the street, including such turnaround.

The maximum height, in feet, for structures other than buildings may not exceed the maximum height for buildings as set forth in Table 2.[1]

Structures other than buildings may be located in a minimum required front, rear or side yard, provided the height of the structure is not greater than its horizontal distance from the lot line, except that:

A solar energy system may be located over any paved parking lot.

Structures shall not interfere with safe stopping sight distance on a street.

Where two or more fences or retaining walls are separated by a distance that is less than the height of the highest such structure, all such structures shall be considered a single structure and their height shall be equal to the combined height of the structures.

A sign, permitted under § 5.2, may be located in a front yard.

A solar energy system may be located over any paved parking lot.

Buildings for which a building permit application has been submitted before January 1, 2024, may be extended, altered, reconstructed or structurally changed so long as the total gross floor does not exceed that in Table 4.4.2.1 below based on lot area. For the purposes of this § 4.4.2, extension, alteration, reconstruction, and structural change shall not include any construction which involves demolition of more than 50% of the primary building's shell exclusive of demolition of a single-story attached garage. For purposes of calculating the percentages of any demolition under this subsection, all demolition shall be taken into account which commenced, or could have commenced, pursuant to an issued permit within two years prior to the date of any request for any permit to construct, reconstruct, alter, add, extend or otherwise structurally change any structure.

For the purposes of § 6.12.3.7(a), Table 4.4.2.1 shall be used to determine the gross floor area permitted based on a proof plan.
