What does the new zoning allow on your street?

About this map

A public reference showing what Cambridge’s 2025 multifamily zoning allows on each lot, and what residents are tracking in the development pipeline.

The two layers

Eligibility shades each parcel by what the ordinance permits — 4 stories by right everywhere, 6 stories on lots over 5,000 sq ft that make 20% of homes permanently affordable. A fact about zoning, not a prediction.

Tracked projects carry a confidence tier set by the evidence behind each one — an issued permit, a scheduled meeting, a listing, or an uncorroborated tip.

What this is not

Not a real-estate or investment tool, and not a prediction of which homes will be redeveloped.
