The building types defined in this section are allowed within the BC, DN, WG, and PWD Districts. The design standards and regulations that apply to each building type are in addition to those required within each zoning district.
A.
Shopfront building type.
(1)
The facade of the shopfront building type is placed at or close to the front lot line with an entrance generally at sidewalk grade. Pedestrian-oriented retail or office uses are generally located on the ground floor with upper floor typically designed for residential, hospitality, or employment uses. The shopfront building type is characterized by:

(a)
Massing.
[1]
Maximum length of building wall along a street shall be 200 feet.
[2]
Buildings must have a break in facade at least every 50 feet from the previous break or the end of the building. A facade break may be met through the use of architectural features (such as bay windows, porches, porticos, recessed doorways, etc.), through changes in building material or finish or by other similar means.
(b)
(c)
Entrances.
(d)
Corner articulation.
B.
Midrise building type.
(1)
The midrise building is a key characteristic of an urban downtown providing higher-density buildings where the building line generally meets the lot line. Midrise buildings may include a vertical mix of uses (such as ground-floor retail or service with upper floors residential, service, or offices), or single-use building (such as residential or office).

Standards.
(a)
Massing.
[1]
Maximum length of building wall along a street shall be 200 feet.
[2]
Buildings must have a break in facade at least every 50 feet from the previous break or the end of the building. A facade break may be met through the use of architectural features (such as bay windows, porches, porticos, recessed doorways, etc.), through changes in building material or finish, or by other similar means.
(b)
Windows.
[1]
Minimum 30% window coverage on first floor.
[2]
Minimum 15% window coverage above the first floor.
[3]
Individual window proportions shall be greater in height than width.

(c)
Entrances.
[1]
Main building entrances shall be accentuated; permitted accents include: recessed, awning, canopy, portico, or overhang.
[2]

[3]
A midrise building may also have a forecourt entrance. A forecourt entrance is when a small courtyard is placed on the front lot line of the building. A forecourt may occupy no more than 35% of the length of the front facade and must be placed in the middle of the building's front facade such that no less than 25% of the length of the front facade is located on either side of the forecourt. The forecourt shall be no more than 30 feet deep and no wider than half of the building's height.
(d)
Corner articulation.
C.
Rowhouse building type.
(1)
Description.
(a)
The rowhouse building type is a residential structure typically located on a narrow lot, that shares a party wall with a structure on an adjoining lot. Rowhouses typically range from two to four stories and are also called townhouses and attached houses. Rowhouses are prominent in the Downtown Neighborhood District in particular and help provide a broad choice of housing types within the City.
(b)
Rowhouses shall be no more than 30 feet wide, and the front facade shall be located near the front lot line.
(2)
Standards.
(a)
Windows.
[1]
Individual window proportions shall be greater in height than width.
[2]
Exterior window guards (e.g., security guards) shall be integrated with the design of the building.
[3]
Windows shall be placed in a consistent pattern within the first floor, floors two through the penultimate floor, and the top floor.
(c)
Entrance types.
[1]
Stoop.

The elevated stoop serves to engage the sidewalk and ensure privacy within the building.
[b]
The stairs of the stoop align with, or near to, the lot line.
[c]
The stairs to the stoop may be perpendicular or parallel to the sidewalk.
[d]
The stoop may have an awning, porch, or portico.
[e]
A low wall, fence, or hedge may be provided to define the frontage line.
[2]
[3]
Lightwell.
[a]
In the lightwell entrance type, the setback of the main building facade features either an elevated terrace or recessed lightwell.
[b]
The lightwell entrance type allows natural sunlight to enter the floor below grade and often serves to allow an outside entrance from the ground floor and the one immediately below.
[c]
Neither the top of the terrace nor the bottom of the lightwell shall be more than six feet in vertical distance from the sidewalk. In no instance shall the distance between the top of the terrace and the bottom of the lightwell be more than 10 feet.

E.
Civic. Owing to its special and public or quasi-public use, the civic building type is designed to stand out from the form of the adjacent area. Civic buildings are often architecturally distinctive buildings that occupy prominent spaces in the community. The civic building type requires a special use permit and site plan approval from the Planning Board in all districts. Civic buildings do not need to be institutionally or government owned. For example, civic buildings could include theaters.
