What Is COMAR?
Maryland State agency regulations are compiled in the
Code of Maryland Regulations (COMAR). COMAR contains 36 Titles, with each Title corresponding to a department or agency. Each regulation is assigned a unique four-part codification number.
COMAR Codification System
Under the COMAR codification system, every regulation is assigned unique four-part codification number by which it may be identified.
All regulations are arranged by title. Each title is divided into numbered chapters, and each chapter into numbered regulations.
A regulation may be divided into lettered sections, a section divided into numbered subsections, a subsection divided into lettered paragraphs, and a paragraph divided into numbered subparagraphs.
- COMAR regulations are effective to date.
- COMAR is updated biweekly corresponding with the effective dates in the most current Maryland Register issue.
Under State Government Article, §7-217, Annotated Code of Maryland, the printed version of COMAR is the official and enforceable text. Only the official text may be judicially noticed under Courts and Judicial Proceedings Article, §10-203 Annotated Code of Maryland.
