For two-family/two single family, in the URA, B, C zones, there is a minimum building occupancy in
accordance with the following:
(1) Dimensional Standards
URC URB URA
Side Setback (min) See Tables
Rear Setback (min) See Tables
Build-to-Zone (min-max) 10’-25’ 10’-25’ 20’-40’

20’ 20’ 20’
1) Building Massing
Maximum length of Massing is 50’ “B”
(a) A dwelling may have more than one mass.

(b) When a mass is attached to another mass, the masses must be designed with one
or more of the following:
(i) The roofs of adjacent masses run in different directions.
(ii) The roofs of adjacent masses that run in the same direction have at least a 2’
difference in height.
(iii) Adjacent masses are arranged to create an Ell or T shaped building. The leg of

2) Building Frontage
a. Within the URA, URB, URC zones, in order to create a transitional space
between a building’s façade and the public realm that enhances neighborhood
character, a new two-family dwelling or substantial alteration of a single-family
dwelling that adds 50% or more gross floor area must include a covered front
entry that meets the standards below.
I. The covered front entry must be located within the build-to-zone, except
when a pre-existing building is not located within the build-to zone.
5
II. The covered front entry must face the street. This is required for buildings
facing and along the street front within the build-to zone. This is not
applicable for additional structures built behind such buildings and which are
not within the build-to zone.
III. A covered front entry must have a minimum contiguous floor area of six (6)
feet by eight (8) feet, exclusive of any stairs or ramps, for each unit’s entry.
The Planning Board, through site plan review may approve a smaller size but
not smaller than 4’x4’ for each unit.
IV. The roof must cover an area of at least 4’x4’ .
V. At least one side of the covered entry shall be open between 3’ and 7’
above its floor surface.
VI. A front entry may project beyond the front façade of a building or may be
integral to the overall massing and roof form of the building.
VII. Any stair egresses to porches above first floor covered entries must be within
the footprint of the porch and may not project on the exterior of the porch
footprint if it is within the build-to-zone.
6
Illustrative examples:
b. A two-family dwelling may have a shared front entry, or two separate front
entries.
c. When a dwelling or dwelling unit is located to the rear of another dwelling unit
that has a covered front entry, the principal entrance to the rear dwelling may
face the side or rear of the lot. In this case, the covered front entry must be at
7
least 20’ from the lot line unless other means to create a buffer/private outdoor
space to adjoining properties are approved by the Planning Board. The entrance
must meet the requirements for a covered front entry as described above.
3) Parking/Garage Placement
a. General Parking
i. A parking area must be located to the side or rear of a dwelling. No more
than 1 parking space may be located in front of a dwelling’s front façade.
ii. Where a pre-existing parking area in front of a dwelling’s front facade is
proposed to be used in association with a new two-family use: the parking
area may be expanded toward the side of the lot but may not encroach
further in front of the home between the home and the street.
iii. No more than four cars may be parked beside a dwelling. Additional
vehicles must be parked behind a dwelling or inside a garage.
iv. Parking for more than four cars shall be separated by landscaped areas
of at least six (6) feet by six (6) feet.
v. Parking areas behind a dwelling shall be adequately screened to block
car headlights from illuminating adjacent properties
vi. The Planning Board may issue a special permit for alternative parking
configurations when: the proposed design maintains an equal level of
safety and no more than four cars will be visible from a public way

b. Detached Garage Design
i. When a detached garage is located to the side of a dwelling and the garage
doors face and are visible from the street, the width of the detached garage
must be no more than 75% of the width of the principal dwelling on the
property.
ii. Detached Garage Front Setback -20’ min
c. Attached Garage Design
i. When an attached garage is located between two dwelling units, the garage
doors must face the side or rear of the lot.
ii. When the garage door(s) of an attached garage faces and is visible from the
street, no garage door shall be wider than 12’.
iii. For attached garages in the SR, RR, and WSP districts when the garage
doors do not face the street, the façade of the garage visible from the street
shall have window glazing that covers at least 20% of that exterior façade.
4) Screening
a. All exterior mechanical structures must be located along the sides or rear of
structures or screened from view from public ways.
b. All refuse containers must be contained within a structure or screened from view
from a public way and adjacent properties.
