[Amended 4-8-1997; 12-17-2019; 7-12-2022]
The Town Board recognizes an existing and growing need for alternative housing choices from single-family dwellings and larger multifamily developments. The Residence CAA District is intended to provide for low-density residential buildings compatible in scale and form with detached single-family homes to be located in walkable neighborhoods. The provisions contained in this article are intended to maintain the residential character of the site and neighborhood through the regulation of architecture and streetscape design while limiting the location of such properties to those adjoining or within walking distance of commercial areas that provide necessary goods and services.
[Added 7-12-2022]
A. 
The site shall be located within walking distance to a downtown center or existing retail services.
B. 
The site shall be of sufficient size and shape so as to provide for the required buffer, landscaping, and setback requirements.
C. 
The site shall be of sufficient size to provide for adequate parking in accordance with Town standards while still maintaining a residential appearance to the site.
D. 
The site shall be of sufficient size to provide for ample yard space (see § 68-155B) consistent with those of neighboring single-family dwellings.
E. 
The site shall not be located mid-block among other single-family dwellings unless adjacent to institutional uses or a mitigating circumstance exists whereas the goals of this article are better served.
[Added 7-12-2022]
In a Residence CAA District, no building, structure, or premises shall be used or occupied and no building or part thereof or other structure shall be so erected or altered, except for one or more of the following purposes:
A. 
One-family dwelling.
B. 
Two-family dwelling.
C. 
A single three- or four-family dwelling with a side yard adjacent to a property zoned Residence C, Residence CA, Business District, Business 1, Business 2 or General Service T District and having no uses other than accessory uses on the subject parcel. The subject parcel shall meet the requirements of §§ 68-500 and 68-501. The building must have a lobby/foyer from which all units are accessible (via hallways, elevators). No visible entry doors to each individual unit are permitted. Only one visible front entrance shall be permitted, unless a determination is made by the Commissioner of Planning or his or her designee that the architectural character of a preexisting building will be preserved by allowing one additional visible front entrance.
[Amended 3-14-2023]
The uses permitted by special permit from the Town Board after a public hearing shall be the same as those permitted in a Residence AAA District when authorized by a special permit from the Town Board after public hearing, and no other.
The uses permitted as special exceptions by the Board of Appeals after a public hearing shall be the same as those permitted in a Residence AAA District when authorized as a special exception by the Board of Appeals, and no other.
No accessory use and structure shall be permitted in a Residence CAA District except those which are permitted in a Residence AAA District.
