Subsurface waste water disposal – Any request for an accessory apartment shall conform to all provisions of the Maine Subsurface Waste Water Disposal Rules and no dwelling that is served by an on-site wastewater disposal system shall be modified to create an accessory apartment until a site evaluation has been conducted by a licensed site evaluator which demonstrates that a new system can be installed to meet the disposal needs of both dwelling units.
Entrance – The dwelling shall have only one front entrance and all other entrances shall be on the side or in the rear of the dwelling. An entrance leading to a foyer with entrances leading from the foyer to the two dwelling units is permitted.
