A public reference for two questions: what Cambridge zoning lets you build on any given lot, and where new housing is being built or proposed. The goal is to let anyone, without a planning background, see how their city is changing — in one place. We focus on projects that add or reshape housing — new multifamily buildings, redevelopments, teardowns, and Affordable Housing projects.
All of this site's data is open and self-describing. Point an AI assistant (Claude, ChatGPT, etc.) at it and ask questions in plain English — no account or code needed.
