10-50.110.010 Purpose

This division provides illustrations, descriptions and standards for permitted building types, and specifies the transect zones in which they are allowed.

The purpose of these provisions is to ensure development that reinforces and compliments the existing character and architecture found in Flagstaff’s neighborhoods and downtown.

10-50.110.020 Applicability

A.    The requirements of this division shall apply to all proposed development within the transect zones, and shall be considered in combination with the standards for the applicable zone in Chapter 10-40, Specific to Zones, and in the rest of this chapter.

B.    The standards set forth in this division may also be used in the non-transect zones with Director approval.

C.    Civic buildings shall not be subject to the physical requirements of the building type standards in this division.

10-50.110.030 Building Types Overview

This section provides an overview of allowed building types. The name of the building type is not intended to limit allowed uses within a specific building type. For example nonresidential uses (such as a restaurant or offices) may be located within a single-family house, and a commercial block building type may include non-commercial uses. Height regulations are primarily determined by the zone the building type resides within and are provided in Chapter 10-40, Specific to Zones. Specifics of how to measure building height are provided in Division 10-50.30, Building Height.

Table 10-50.110.030.A., Allowed Building Types, provides an overview of allowed building types.

A. Description

 

The carriage house building type is an accessory structure or accessory dwelling unit (ADU) typically located at the rear of a lot (see also Section 10-40.60.030, Accessory Dwelling Units). This structure typically provides either a small residential unit, home office space, or other small commercial or service use that may be above a garage or at ground level. This building type is important for providing affordable housing opportunities and incubating small businesses within walkable neighborhoods.

The carriage house building type is the only detached ADU allowed in transect zones.

The windows and doors of the carriage house need to be carefully placed to ensure privacy for the property owner and neighbors.

This type is appropriately scaled to fit within primarily single-family neighborhoods or medium-density neighborhoods. This type enables appropriately scaled, well-designed higher densities and is important for providing a broad choice of housing types and promoting walkability.

10-50.110.100 Duplex, Stacked

In this stacked duplex, the entry to the right opens to a stair leading to the upper unit, which takes up the entire upper floor. The door to the left opens directly into the lower unit, which takes up the entire lower floor.

 

General Note: The drawings and photos on this page are illustrative, not regulatory.

The scale of this duplex makes it compatible with adjacent single-family houses.

The difference in the form between this duplex and single-family houses in the neighborhood is barely perceivable.

 

 

A. Description

 

This duplex building type is a small to medium-sized structure that consists of two dwelling units, one on top of the other. This type has the appearance of a medium to large single-family home and is appropriately scaled to fit within primarily single-family neighborhoods or medium-density neighborhoods. This type enables appropriately scaled, well-designed higher densities and is important for providing a broad choice of housing types and promoting walkability.

This is the preferred type of duplex on 50-foot-wide lots in Flagstaff neighborhoods not zoned for single-family because it is capable of accommodating two units in a smaller footprint, thus maximizing compatibility in size and privacy to the rear of adjacent units.

10-50.110.110 Duplex, Front-and-Back

Both units in this duplex have private frontages that engage and address the street.

 

General Note: The drawings and photos on this page are illustrative, not regulatory.

The massing of this duplex has the front and back unit offset enough to allow the rear unit to have a private frontage that addresses the street.

This front and back duplex fits into a neighborhood made up of predominately large single-family houses.

 

 

A. Description

 

This duplex building type is a small- to medium-sized structure that consists of two dwelling units, one adjacent to the street and the other attached but tucked behind. This type has the appearance of a medium to large single-family home and is appropriately scaled to fit within primarily single-family neighborhoods or medium-density neighborhoods. This type enables appropriately scaled, well-designed higher densities and is important for providing a broad choice of housing types and promoting walkability.

Four attached townhouses designed as a row of houses.

 

 

A. Description

 

The townhouse building type is a small to medium-sized attached structure that consists of three or more dwelling units placed side by side. This 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 type enables appropriately scaled, well-designed higher densities and is important for providing a broad choice of housing types and promoting walkability. Syn: Rowhouse

A courtyard with communal seating for residents and guests.

 

 

A. Description

 

The courtyard apartment building type is a medium-to-large-sized structure that consists of multiple side-by-side and/or stacked dwelling units accessed from a courtyard or series of courtyards. Each unit may have its own individual entry, or up to three units may share a common entry. This type is appropriately scaled to fit in sparingly within primarily single-family neighborhoods or into medium-density neighborhoods. This type enables appropriately scaled, well-designed higher densities and is important for providing a broad choice of housing types and promoting walkability.

10-50.110.160 Live/Work

This live/work unit has a ground-floor flex space with a two-story residence above. The residence entry is to the far right, and the ground-floor flex space entry is on the corner.

 

General Note: The drawings and photos on this page are illustrative, not regulatory.

 

A. Description

 

The live/work building type is a small to medium-sized attached or detached structure that can be used to provide a mix of uses with ground floor residential, commercial, service, or retail uses and upper floor commercial, service, or residential uses. Ground floor residential uses are not permitted unless permitted in the underlying transect zone. This type is typically located within medium-density neighborhoods or in a location that transitions from a neighborhood into a neighborhood main street. It is especially appropriate for incubating neighborhood-serving commercial uses and allowing neighborhood main streets to expand as the market demands.

 

 

This three-story corner live/work unit stepping down to two-and-a-half stories as it transitions to single-family homes. These units provide incubator space for small, locally owned, neighborhood-serving commercial businesses.

Shopfront frontages are typically found on commercial block buildings.
