Zoning History StoryMaps

We are creating a StoryMap collection to show how the Cambridge Zoning Ordinance and Map have evolved over time. StoryMaps combine maps with text and images into a multimedia online narrative. Starting with a chapter on the 1924 Zoning Ordinance, these StoryMaps explain how zoning was being used at different points in time, the context that surrounded them, and how it affected the growth of the city. More chapters will be added in the future!


Zoning Archive

We have been gathering and digitizing zoning maps and ordinances from over the past 100 years so that you can look at them online. On this page you can read the Cambridge Zoning Ordinance and Building Code from 1924 and look at the very first Cambridge Zoning Map, as well as major changes to the Zoning Ordinance and Map over time. This is not a complete record of zoning ordinances, and they should not be considered official documents for legal purposes. Official copies of City of Cambridge Zoning Ordinances and Zoning Maps are on file at the Office of the City Clerk.
