Understand what Boston allows on your lot before you pay an architect or land-use attorney. Buildability™ reads the current Boston zoning ordinance against your address and returns the district, permitted uses, development standards, and overlay restrictions — plus your Buildability Score™ — in about 20 seconds.
Understanding Boston zoning districts
Boston's zoning is built around a handful of base districts. Residential zones (often R-1, R-2, RM-1, etc.) control single-family and multi-family housing with different lot size, setback, and height limits. Commercial zones (C-1, C-2, C-3) permit retail, office, and mixed-use. Industrial zones (I or M) cover manufacturing, warehousing, and heavy uses. Mixed-use and transit-oriented zones layer housing above commercial. Buildability™ returns your exact district and decodes what it means for your specific Boston parcel.
Overlays and the things that trip people up
Non-conforming uses are the other common surprise in Boston. If your property's existing structure or use predates the current zoning, you may have grandfathered rights — but rebuilding, expanding, or changing use can trigger full conformance with modern code. Buildability™ reads the code history and flags whether non-conforming status applies.
