This section provides description and design standards for individual building types to ensure that proposed development is consistent with the RGC Subarea Plan’s goals for building form, physical character, land use, and quality.
Each building shall be designed in compliance with the applicable general requirements in Chapter
19.50 UPMC and all applicable requirements of the Washington building and fire codes as amended and adopted by the City.
Development standards for each building type generate the individual buildings on a block that, collectively with other buildings, shape the form of the public realm.
The standards to shape and locate buildings are based on their physical characteristics and compatibility. The successful fit of a new project into an existing character depends on how it relates to neighboring buildings to its side and rear in terms of setbacks, height, massing, scale, and arrangement of shared and open spaces.
Architectural features such as porches, stoops, bay windows, balconies and cornices can project into the setback area. In the RGC, balconies, cornices, awnings, stands selling magazines, fruits, vegetables, or flowers may project into the public right-of-way, subject to a right-of-way permit. Encroachments animate street life and should not affect pedestrian movement and maintenance of utilities.
Accessory structures: The height or footprint of an accessory structure may not exceed the height or footprint area of the principal structure.
A. Multiplex. A multiplex is a medium-sized structure that consists of three to six side-by-side and/or stacked dwelling units, typically with one shared entry or individual entries along the front. The multiplex should have the appearance of a medium-sized family home and is appropriately scaled to provide a transition from single-family neighborhoods into higher density areas. The multiplex type enables appropriately scaled, well-designed higher densities and is important for providing a broad choice of housing types and promoting walkability.

B. Townhouse. A townhouse is a small- to medium-sized building comprised of three or more attached dwelling units arrayed side by side, with the ground floor raised above grade in order to provide privacy for ground floor rooms. The primary building sits at the front of the property, with the garage at the rear, separated from the primary building by a rear yard. Each dwelling unit is directly accessed from the front yard/street. Garages must be located and accessed from the rear of the lot.
This building type is typically located within medium density neighborhoods or in a location that transitions from a primarily single-family neighborhood into a neighborhood main street. This building type enables appropriately scaled, well-designed higher densities and is important for providing a broad choice of housing types and promoting walkability.
The front elevation and massing of each row-house building may be either symmetrical or asymmetrical, repetitive or unique in disposition, if the delineation of each individual unit is evident.

C. Live-Work. A live-work is a small- to medium-sized attached or detached structure that consists of a single dwelling unit above and/or behind a flexible ground floor space that can be used for home-office uses such as residential, personal and general service, small-scale craft production or retail uses. Both the ground floor flex space and the unit above are owned by one entity.
This building type is typically located within medium density neighborhoods or in a location that transitions from a neighborhood into an urban neighborhood street. It is especially appropriate for incubating neighborhood-serving retail and service uses and allowing neighborhood main streets to expand as the market demands. Garages must be located in the rear of the lot. The workspace is accessed directly from the primary street, and the living space at the rear or above is accessed directly or indirectly from the working space.

D. Court. A court building accommodates five or more dwelling units vertically and horizontally integrated arranged to share one or more common courtyards. The courtyard is intended to be a semi-public outdoor room that is an extension of the public realm.
The main entry to ground floor units should be directly off the courtyard or from the primary street. Access to second story units should be directly from the courtyard through stairs. Elevator access, if any, should be provided between the underground garage and courtyard-podium only.
This building type is typically located within medium to high density neighborhoods and is subject to the City’s design standards. It is important for providing a broad choice of housing types including affordable housing.
This building must include shopfront first floor architecture in the shopfront overlay which may be in the form of live-work units.

Ground floor units on primary or secondary streets must have their entrances directly onto the street. Nonstreet front ground floor units shall access to a courtyard or plaza. Access to upper story units should be directly from a common entrance or from an internal lobby courtyard or plaza.
To differentiate between the ground floor and upper stories along street frontages alternate exterior materials shall be used. Examples would include brick or stone.
Parking is located behind/beside or under the building.
This building type is typically located within higher density neighborhoods and is subject to the City’s design standards. It is important for providing a broad choice of housing types including affordable housing.
Must include shopfront first floor architecture in shopfront overlay which may be in the form of live-work.

F. Commercial Building. A commercial building is a building type designed exclusively for commercial uses for retail, restaurants, services and/or offices. Commercial buildings may be single story or have multiple stories. Ground floor pedestrian access is provided from the primary street in midblock locations and from primary and secondary streets in corner locations. Upper floors are accessed through a street level lobby.
The primary shared common space is the rear or side yard designed as a courtyard. Courtyards can be located on the ground, or on a podium, or on a parking deck, and must be open to the sky. Side yards can also be formed to provide outdoor patios connected to ground floor commercial uses.

Upper floors are accessed through a street level lobby. Location: mid-block or corner. Parking is underground garage, surface, tuck under, or a combination.
The floor-to-ceiling height of the first floor is greater than the rest of the floors to accommodate the unique needs of commercial space and increase the comfort of occupants and guests. The main entrance to each ground floor tenant bay should be directly from the street. Parking is accommodated in an underground garage, surface lot, structure, tuck under facility, or some combination.

The building can be designed for occupancy by retail, service, and/or office uses on the ground floor, with upper floors configured for retail, service, office, and/or residential uses. The main entrance to each ground floor storefront and the theater or big box retail is directly from the street. Entrance to the upper levels of the building is through a street-level lobby accessible from the street or through a side yard.
Location: mid-block or corner. Parking is underground garage, surface, tuck under, or a combination.
