Likewise drainage requirements of 248 CMR, when applicable must be satisfied. Also to meet accessibility requirements of 521 CMR for existing buildings with exit constraints, local jurisdictions may allow encroachment onto public right-of-way.
The projection of any structure or portion thereof shall be the distance measured horizontally from the lot line to the outermost point of the projection.
A part of a building erected below grade that is necessary for structural support of the building or structure shall not project beyond the lot lines, except that the footings of street walls or their supports which are located at least 8 feet (2438 mm) below grade shall not project more than 12 inches (305 mm) beyond the street lot line.
