and, for a number of use categories, exceptions—i.e., those uses that might appear to fall
within the use category, but are included in another use category.
Use Types
The specific use types included in each use category identify specific principal uses that are
considered to possess the characteristics identified for the use category. For example, single-family
detached dwellings, duplex dwellings, single-family attached dwellings, multifamily dwellings, and
manufactured home dwellings are use types in the Household Living use category.
C.
Development with Multiple Principal Use Types
A development may include multiple principal uses, provided each principal use is a principal use type
allowed in the applicable zoning district and the development complies with any use-specific standards
applicable to each of the included use types. If a use within a development is determined to be an
accessory use to a principal use in the development, such accessory use shall be subject to the accessory
use standards in
Section 4.3, Accessory Uses and Structures.D.
Agricultural and Animal Related Uses Classification
Agriculture Uses
The Agriculture Uses category is characterized by activities related to the production of field crops,
fruits, vegetables, ornamental and flowering plants, and the breeding, raising, or keeping of
livestock, poultry, swine, or other animals for food or other marketable products. The Agriculture
Uses category also includes silvicultural activities related to the planting, management, protection,
and harvesting of trees for timber or other forest products. Example use types include farms,
forestry, and greenhouse and nursery production. Also included are garden centers, and community
gardens. This use category does not include the processing of animal or plant products for
wholesale or retail sale purposes, which is generally considered an industrial manufacturing use
type. Accessory uses may include offices, storage areas, barns, irrigation systems, and repair
facilities related to the agricultural activities.
Animal Related Uses
The Animal Related Uses category includes use types that provide services, general care, and
boarding services for domestic animals. Example use types include stables, kennels, and veterinary
clinics. Accessory uses may include offices, storage areas, stables, outdoor exercise pens or runs,
and limited retail sales.
E.
Residential Uses Classification
Household Living Uses
The Household Living Uses category includes use types providing for the residential occupancy of
a dwelling unit by a single family. Tenancy is generally arranged on a month-to-month or longer
basis. Example use types include single-family detached dwellings, duplex dwellings, single-family
attached dwellings, multifamily dwellings, bungalow court, pocket neighborhood, and
manufactured home dwellings. In accordance with State law, dwelling units providing a single
housekeeping environment for groups of six or fewer persons with physical, emotional, or mental
disabilities are treated as any other household living use, and not as a group living use. This use
category does not include residential use types that generally involve some level of managed
personal care for a larger number of residents (e.g., congregate living facilities), which are
categorized as group living uses. It also does not include use types where persons generally occupy
living units for periods of less than 30 days (e.g., hotel/motel), which are categorized as visitor
accommodation uses. Accessory uses common to household living uses include recreational activities,
raising of domestic pets, hobbies, swimming pools, and parking of the occupants’ vehicles. Some
accessory uses (e.g., home occupations and accessory dwelling units) are subject to additional
regulations (se
e Section 4.3, Accessory Uses and Structures).
