Comprehensive Ordinance List PREFACE TO THE ENVIRONMENT CODE On July 3, 2003, the Board of Supervisors and the Mayor adopted this Municipal Environment Code. The Environment Code was developed to consolidate the City's ordinances governing protection of the environment, natural resources and sustainability that were previously scattered throughout the Administrative Code. This electronic version of the City and County of San Francisco Municipal Code is updated as amending legislation is approved. New Ordinance Notices are inserted where applicable to call the user's attention to material that has been affected by legislation that has been passed but is not yet effective. Any references to such legislation are also compiled in a table at the end of this Code. The amendments are then incorporated into the Code when they become effective. Beginning with ordinances passed in 2011, all ordinances affecting this Code are summarized in a table that lists the identifying information (ordinance and file numbers), effective date, short title, and sections affected for each such ordinance. Users should note that the operative date of an ordinance may be later than the effective date of the ordinance. A delayed operative date will be noted in the ordinance. This Code may contain various Editor's Notes (explaining the disposition of or cross referencing various provisions), and/or Codification Notes (documenting scrivener's errors and the like found in the underlying ordinances). Such notes have been inserted by the publisher for the convenience of the user or as historical references. They have not been approved or adopted by the City and County of San Francisco, and are of no legal force or effect.
