Information Bulletins

or Select by Topic


Information bulletins provide consistent and uniform interpretation of the codes, clarify code issues as they relate to new construction and new technologies, and explain new regulations.

Information bulletins supersede most of the previously published Rules of General Application (RGA's), Memorandums of General Distribution (MGD's) and other related public information handouts.

Please note that some provisions or interpretations of the code as written in the superseded RGA's and MGD's are no longer applicable due to subsequent code changes. Information from these outdated documents is not included in the new LADBS Information Bulletins.
