District of Columbia Research Guide

The D.C. Office of Documents and Administrative Issuances (ODAI) publishes the D.C. Municipal Regulations (DCMR) and the D.C. Register. The D.C. Register is published weekly on a Friday. If the Friday is a public holiday, the Register is published on the Thursday.

Mayor's Orders can be searched by either the order number or by conducting a calendar search, if the month and year are known.

Mayor's Memoranda are searchable by the Memorandum number or by calendar.

From 1967-1974, the District of Columbia was governed by a Commissioner. This office was established by Congress, and was eventually replaced by the current mayoral position.

To locate Commissioners' Orders from 1952-1972, call the Office of the Secretary at 202-727-5090 or email dcdocuments@dc.gov for assistance.
