Cottage housing is intended to address the changing composition of households, and the need for smaller, more diverse, and often, more affordable housing choices. Providing for a variety of housing types also encourages innovation and diversity in housing design and site development, while ensuring compatibility with surrounding single unit detached dwelling developments.
2.
Ownership. Cottage housing developments may be sited on one commonly owned parcel with individual cottages owned in a condominium, cooperative, or similar arrangement, or cottages may be on individual lots with shared amenities and facilities owned in common.

a.
Maximum Floor Area. A cottage shall enclose an area of not more than twelve hundred (1,200) square feet.

c.
Maximum height shall not exceed twenty five (25) feet.
d.
A minimum of seventy-five (75) percent of the cottages front entrances must face the common open space or a street.
e.
Orientation of Cottages. Cottages shall be clustered around the common open space.

4.
Community Buildings. Cottage housing developments may include community buildings that provide space for accessory uses such as community meeting rooms, exercise rooms, day care, or community eating areas. They shall have a footprint of no more than eight hundred (800) square feet and may not exceed one story in height. Their design, including the rooflines, shall be similar to and compatible with that of the cottages within the cottage housing development.
5.
Common Open Space. Each cottage cluster shall have common open space in order to provide a sense of openness and community of residents. Common open space is subject to the following standards:
a.
Each cottage cluster shall contain at least one thousand five hundred (1,500) square feet of common open space regardless of the number of cottages in the cluster, b. Parking areas, required yards, private open space, and driveways do not qualify as common open space.
6.
Parking. Cottage housing developments shall have at least one space for each cottage.
7.
Interior Fences. Fences on the interior of the cottage housing development shall not exceed three feet in height and shall not consist of solid board fencing.
8.
Existing Structures. On a lot or parcel to be used for a cottage housing development, an existing single unit detached dwelling that may be nonconforming with respect to the requirements of this section may remain, but the extent of its nonconformity may not be increased. Such dwellings shall count towards the number of cottages allowed in the cottage housing development.
9.
