The Code of Massachusetts Regulations (CMR) houses the state’s Administrative Law (regulations), including administrative orders and decisions, promulgated by state agencies pursuant to the Administrative Procedures Act (M.G.L. c. 30A).
Updates (or filings) are published every two weeks in the Massachusetts Register by the Secretary of the Commonwealth’s State Publication and Regulations Division.
Each agency in Massachusetts is assigned a three digit title number. The first digit represents the cabinet office involved, while the last two digits represent the specific agency. The digit title number is then broken down into chapters and sections. For example:
105 CMR (digit title number) – Department of Public Health
105 CMR 125.004 – Types of Licenses
The CMR also consists of emergency regulations, which an agency can adopt temporarily until certain requirements are met. For more information on the rules and procedures involved in filing regulations, agency and title number indexes, as well as a list of filing and publishing dates, please see The Regulations Manual or visit the State Publication and Regulation Division’s website.
