Finding Regulations

Regulations, like statutes, are published in subject arrangements called codes. Regulations explain the details necessary to implement laws.

  • The regulations of Maryland are published in the Code of Maryland Regulations (“COMAR”).
  • The regulations for the United States government agencies are published in the Code of Federal Regulations (“CFR”).

To find any specific regulation in a code, you need its citation. You may have seen citations to both COMAR and the CFR on the Peoples Law Library.
