Please be advised that the regulations below are not the official version of the regulations. As is the case with all state regulations, the official versions are available from the Secretary of the Commonwealth' s State Publications and Regulations Division, through the State Bookstore, Room 116, Boston, MA 02133 or by calling (617) 727-2834. Official regulations also may be ordered from the State Bookstore on-line at http://www.sec.state.ma.us/spr/sprcat/catidx.htm. While the Department strives to keep the regulations included on this site current, that is not always possible. In the case of any discrepancy between the version on this site, and the official Code of State Massachusetts Regulations published by the Secretary of State, the Secretary of State's version takes precedence.
