The purpose of permitting an accessory apartment is to:
A. Provide homeowners with a means of obtaining, through tenants in an accessory apartment, rental income, companionship, security and services, and thereby to enable them to stay more comfortably in homes and neighborhoods they might otherwise be forced to leave;
B. Add inexpensive rental units to the available housing within the Town to meet the needs of smaller households, both young and old;
C. Make housing units available to moderate income households who might otherwise have difficulty finding homes within the Town;
D. Develop accessory apartments where single family dwellings are allowed that are appropriate for small households at a variety of stages in the life cycle, thereby lessening fluctuations in neighborhood demand for particular services.
