A. Purpose: This section sets forth standards for development of individual building types to achieve the intended physical character of each zone and provide housing choices and small businesses as amenities within walkable neighborhoods.
B. General Building Type Standards:
1. Scale: Building types are categorized into house-scale buildings and block-scale buildings. The individual types within these two (2) categories are determined by the intended physical character of each Form-Based Zone. See Figure 14-2H-6B-1 (Example Of House-Scale And Block-Scale Buildings) for further details.
2. Design Site Size: The design site size standards for each building type in section 14-2H-2 (Zones) generate pedestrian-oriented buildings that accommodate the automobile while not letting it visually dominate the fronts of buildings and streetscapes. The design site size standards identify the range of design site sizes on which the given building type is allowed to be built.
3. Building Types Per Design Site: Each design site shall contain only one primary building type, except as follows:
a. Where allowed by the zone and as allowed in sub-section 14-2H-6C (Carriage House), one (1) carriage house is allowed in addition to the primary building type;
b. Certain building types may consist of multiple individual buildings per design site as specified in Item 2 of each building type. For an example of a building type where a design site may include multiple individual buildings, see Cottage Court (14-2H-6H).
4. Building Types Per Parcel: More than one (1) building type is allowed on a parcel that contains multiple design sites that meet the standards of this section. See Figure 14-2H-6B-2 (Example of Multiple Design Sites On An Existing Parcel).
5. Location Of Frontage: Each building type shall have at least one (1) frontage type along the front street, side street or a civic space. The Cottage Court building is only required to have a frontage type on the court. The primary building entrance shall be through said frontage type.
6. Diversity Of Building Types: Except in the T4MS zone, there shall be a mix of at least two (2) different primary building types within each block, using only the types allowed in the zone.
7. Number Of Units: The standard regarding the minimum number of units per building listed in Item 2 (Number Of Units) only applies to residential uses. Where a building type is occupied by a nonresidential use, only the maximum number of units per building listed in Item 2 (Number Of Units) applies.
C. Carriage House:
