Rules By Department

---

IMPORTANT NOTICE (April 26, 2024): Due to a backlog of adopted rules that need to be posted on the Office of the Secretary of State’s website, individuals interested in obtaining a copy of the most recently adopted version of an agency rule should directly contact the agency that administers the rule to request a copy of such. Thank you.

Rule chapters in the Code of Maine Rules (CMR) are arranged by unique numbers which identify the department, departmental unit, and chapter. For example, 01-015 CMR Chapter 1 represents Chapter 1 of the Department of Agriculture, Conservation and Forestry, Maine Milk Commission. They are listed in alphabetical order, by department, on this page.

Click on the highlighted departmental designation to reach a complete list of its current chapters. We also offer advice if you're having trouble trying to view these chapters.

Each rulemaking agency designates a liaison as a single point of contact on rule inquiries.

Important Note: Posting of adopted rules on the APA web site is most often up-to-date within a week of filing.
