Purpose. The purpose of § 250-5.1. is to define all dimensional regulations related to allowable lot area, width, frontage, including dimensional regulations for all districts, and to clarify the regulations for dwellings per lot, lot size exceptions and reduction of occupied lots.
A.
Wetlands or land under water. In all districts, no more than 10% of the required lot area, as defined in this Article V, shall consist of wetlands or land under water.
B.
Lot area, width, shape and frontage. Except as provided in Subsections C, D and § 250-5.5, no building, except a detached building of accessory use, shall be constructed on a lot having less area than the "Required Lot Area" or having less width than the "Required Lot Width Through Building," specified in the following table for the district in which said lot is located:
[Amended 11-16-2021 STM by Art. 18]

|---|---|---|---|
Residence A | 40,000 | 175 | 100 |
Residence B | 80,000 | 175 | 100 |
Outlying | 80,000 | 175 | 100 |
Dimensional requirements with sewer | |||
Limited Business/Residential | 40,000 | 100 | 100 |
Commercial | 40,000 | 150 | 100 |
Office Park and Industrial | 60,000 | 200 | 150 |
(1)
An area of access is the portion of the lot between the accepted or approved Town way and the point where the required lot width through the principal building is reached.
(2)
Lot shape. Unless approved in connection with a subdivision plan under MGL c. 41, or with a development plan review under this bylaw, lots shall maintain, beyond the principal building, a lot width as defined in Subsection B of the definition of "lot" in § 250-2.1, and measured from side lot line to side lot line to be a minimum of 50% of the required lot width as defined in this Subsection B above. Any lot area width less than the minimum described above shall not be calculated in the required area dimension or used for any other purpose.
(3)
Frontage can be reduced by 50% when it provides the only access to one dwelling unit on a lot which is equal to at least twice the minimum lot area requirement, provided that:
(a)
Not more than two lots with such reduced frontage can be placed side by side.
(b)
There shall be at least two lots with the otherwise required 100% frontage adjacent to any two 50% frontages.
(c)
Each 50% frontage lot must be the access to its own lot.
(d)
No more than 30% of the required lot frontage can be encumbered by easement or used for a common driveway.
(e)
Entrances and/or driveways to lots in all districts must be made from an accepted or approved Town way.
(4)
The frontage of a lot must be available for access.
(a)
The Planning Board shall determine that the frontage is adequate and available for safe vehicular access in accordance with its Rules and Regulations Governing the Subdivision of Land[1] and/or when the Building Commissioner requests a determination.
(b)
Except for public utilities in place at the time of the passage of this provision, no more than 30% of required frontage shall be encumbered by easements, drives, access strips, or ways of any type.
C.
Recreation District. In a Recreation District, except for municipal recreation uses, the following minimum areas and frontages are required:
(1)
The minimum frontage for all uses shall be 200 feet.
(2)
For a golf course, the minimum lot area shall be at least 120 acres.
(3)
For all other uses, the minimum lot area shall be at least two acres of lot area plus sufficient area for the proposed use as determined by the standards contained in Time-Saver Standards for Site Planning, Joseph DeChiara and Lee E. Koppleman, McGraw Hill, New York City, 1984, pages 424 and 425.
D.
Retail Commercial, Commercial and Office Park and Industrial Districts.
(1)
In a Retail Commercial or Commercial District, no building shall be constructed as a dwelling or so used on a lot having less area or width than the amount required for the construction of a dwelling in an abutting Residence A, Residence B or Outlying District or where more than one such district abuts, in the particular district having the greatest length of common boundary with the Retail Commercial or Commercial District in question.
(2)
In an Office Park and Industrial District, the following minimum areas and frontage are required:
E.
One dwelling per lot. In all districts, not more than one building on each lot shall be constructed as a dwelling or so used except as provided in Section 3.4.
F.
Reduction of occupied lots. No lot on which a building is located in any district shall be reduced or changed in size or shape so that the building or lot fails to comply with lot area, width, setback or yard provisions of this bylaw, or, if such building or lot already fails to comply with said provisions, such reduction or change would bring about a greater degree of noncompliance with said provisions. This prohibition shall not apply, however, when a portion of a lot is taken or conveyed for a public purpose.
