The degree to which the proposed use furthers the Town's interest in providing a range of housing types, where applicable. 3. The degree to which the application addresses the following design standards: i) Achieve compatibility with the established pattern of uses in the district. The Residential 4 District consists primarily of single-family dwellings near the Stevens Memorial Library Area and off of Massachusetts Avenue, and more compact neighborhoods with a mix of residential uses toward Waverly Road. New construction or substantial alteration of buildings must compliment and reinforce the design features of these neighborhoods. ii) Achieve design compatibility with architectural features and exterior materials of surrounding structures. iii) Preserve existing structures of historic value.

For purposes of zoning compliance, additions or alterations that adhere to the U.S. Secretary of the Interior's Standards for the Treatment of Historic Properties will generally be presumed to maintain or promote such status. iv) Preserve established, mature vegetation. b. The right to apply for a special permit to convert an existing dwelling shall extend to any dwelling to be converted for use as a dwelling of not more than five (5) residential units, and meeting all requirements of the State and Town Statutes and Bylaws, including the Health Codes, Building Codes, Zoning Laws and Zoning Bylaws.
