MassBuilds is the definitive inventory of past, present, and projected real estate development in Metro Boston and across Massachusetts. MassBuilds brings MAPC's longstanding efforts to track development into the modern age with a fully-interactive website that allows users to search, filter, summarize, and download information about over 3,500 residential and commercial development projects in the region.

This data inventory is designed to help analysts, planners, real estate developers and community advocates understand development in our region by compiling reliable, project-level data not available elsewhere. Available attributes about each project include housing units and commercial square footage, status, year of completion, parking availability, proximity to transit, WalkScore™ and other information.
