[Added 7-7-1992]
It is the purpose of this ordinance to provide an opportunity, in locations where adverse impacts do not result and in a manner consistent with the Comprehensive Plan, for the creation of small apartments within the existing structure of owner-occupied single-family detached dwellings. It is the intent of the ordinance to meet the special housing needs of small households and to allow for the efficient use of the Town's existing stock of single-family dwellings. It is also the intent of this ordinance to increase compliance with building and fire codes, preserve neighborhood stability and reduce the impact of foreclosure and deferred property maintenance, thereby preserving property values and the health, safety and general welfare of the community.
As used in this ordinance, the following terms shall have the meanings indicated:
ACCESSORY APARTMENT
A dwelling unit which is subordinate to a permitted principal one-family residence use in terms of size, location and appearance, and is located within the principal structure.
