Release of New LADBS Information Bulletins

The City of Los Angeles Department of Building and Safety (LADBS) is extremely pleased to announce the publication of the new LADBS Information Bulletins. These bulletins will provide consistent and uniform interpretation of the codes, clarify code issues as they relate to new construction and new technologies, and explain new regulations.

These bulletins are categorized into the following topics (see Matrix 1 - Information Bulletin Index):

General Information
Building Code
Electrical Code
Elevator Code
Mechanical Code
Plumbing Code
Zoning Code

The new LADBS 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. For cross reference purpose, a matrix of previously issued documents is provided to allow historical tracking of all superseded RGA's, MGD's and other public information that have been converted into the new format (see Matrix 2 - Cross Reference Index to Previously Issued Public Information).

Please note that some provisions or interpretations of the code as written in the superseded RGA's and MGD's are no longer applicable due to subsequent code changes. Information from these outdated documents is not included in the new LADBS Information Bulletins (see Matrix 3 for a list of Obsolete RGA's and MGD's).

LADBS will continue to update and publish new Information Bulletins in order to ensure constant and uniform interpretation of codes and regulations. As part of our continuing effort to enhance customer service and assist the construction industry, all of the new and updated LADBS Information Bulletins will be made available on the Department's Internet web site at
