Zoning Ordinance
About the Zoning Ordinance
As a public service, this page provides links to the full text and associated maps of the Cambridge, Massachusetts Zoning Ordinance. Our goal is to make zoning more accessible by placing the Zoning Ordinance on the Web. The Ordinance is a complex legal document . Reading about some of the underlying principles of zoning and land use planning discussed in The Zoning Guide will provide necessary information and make the Ordinance easier for the general public to use.
For
a primer on the different aspects of zoning in Cambridge go to the Zoning Guide.
There is an interim period between the date when the City Council adopts a text or map amendment to the Zoning Ordinance and the revision date of this web site. Zoning text and map amendments, as well as corrections, will be placed on-line as available. The web version of the Zoning Ordinance of the City of Cambridge currently includes all text amendments approved by the City Council up to Ordinance #1330 approved on September 21, 2009.
Viewing the On-Line Zoning Ordinance
Both the zoning text and the zoning maps are available on line only in Portable Document Format (PDF) format. In order to view the text and map files in PDF format, you will need at least version 5.0 of the free Adobe Acrobat viewer. Use of an earlier version may result in errors or limited capabilities. The most recent version of the Acrobat Reader should work well with most version 5.0 or higher internet browsers.
Generally, text files in PDF format can be printed with little loss of legibility. Conversion to PDF format sometimes compromises legibility of map features when printed. If you wish to obtain a current paper copy of one of the maps referenced by the Ordinance, contact the City Clerk's office at 617/349-4260.
