Mass. Gen. Laws ch. 138 § 16C
Premises, except those of an innholder and except such parts of buildings as are located ten or more floors above street level, located within a radius of five hundred feet of a school or church shall not be licensed for the sale of alcoholic beverages unless the local licensing authority determines in writing and after a hearing that the premises are not detrimental to the educational and spiritual activities of said school or church; but this provision shall not apply to the transfer of a license from premises located within said distance to other premises located therein, if it is transferred to a location not less remote from the nearest school or church than its former location. Any applicant who has been denied a license under this section shall have the right to an appeal under section sixty-seven.
In this section a church shall mean a church or synagogue building dedicated to divine worship and in regular use for that purpose, but not a chapel occupying a minor portion of a building primarily devoted to other uses, and a school shall mean an elementary or secondary school, public or private, giving not less than the minimum instruction and training required by chapter seventy-one to children of compulsory school age. This section shall not apply to an extension of licensed premises provided said extension does not exceed fifty feet.
