No dwelling shall be erected on a lot that has less than 60 feet of frontage.

Each dwelling must have a separate lot area of at least 6,000 square feet. In the case of a one-family dwelling, there shall be not less than 900 square feet of living space above the foundation. In the case of a two-family dwelling, there shall be not less than 900 square feet of living space for the first dwelling unit and not less than 500 square feet of living space for the second dwelling unit. In the case of a two-family dwelling authorized as a special permit on a lot having less than 40 feet of frontage, the first dwelling unit may have not less than 750 square feet of living space and the second dwelling unit may have not less than 500 square feet of living space. Each such dwelling authorized as a special permit may have a lot area of not less than 4,000 square feet. All buildings, including accessory buildings, shall not cover more than 35% of the area of the lot.

The impervious surface area of any lot shall not exceed 40%; provided, however, that sidewalks, swimming pools and entrance pathways that lead to a front door shall not be included in the calculation of impervious surface area for the purposes of this section. Notwithstanding the provisions of this subsection, impervious surface coverage may exceed 40%, but shall not exceed 45%, where it is established to the reasonable satisfaction of the Chief Building Inspector that the disposition of rainfall and other surface water will comply with standard engineering practices/calculations of water percolation, or that the property will provide dry wells with sufficient capacity to retain and dispose of rainfall and surface water on site.

No building shall be raised, erected or altered in a Residential A District, the height of which exceeds two stories and/or the height of which exceeds the following:

For the main roof area of all dwellings, the slope shall be not less than four vertical over 12 horizontal. For gambrel or other main roof profiles composed of two or more segments of differing slope, the average slope of all segments shall be no less than four vertical over 12 horizontal. The slope ratio requirements shall not be applicable to dormers, one-story wings on multistory buildings, or secondary roof area. See accompanying illustration of roof pitches.

Accessory buildings may occupy 40% of the required area of the rear yard up to an average height of 12 feet. The yard area occupied by such accessory building shall, however, be included in computing the maximum percentage of the lot area which may be built upon. No accessory building shall be nearer any front property line than 45 feet, and accessory buildings must be at least two feet from the rear and side property lines.

No accessory buildings, including garages, shall be hereafter altered so that any part thereof shall contain a room or rooms designed for dwelling purposes.
