Building in Boston: Local Market Context
Boston consistently ranks among the most expensive places to build in the country, and the reasons stack on top of each other: extremely limited buildable land in a city that's largely built out, a strong union labor market that keeps wage scales high, and, in many established neighborhoods, historic district or preservation review that constrains exterior materials, massing, and design in ways that add both cost and time to a project.
New England's climate brings its own requirements — deep frost lines mean foundations need to go well below grade, and older, smaller urban lots often require careful site work to fit a modern build within tight setbacks and easement constraints. Most residential construction activity within the city itself skews toward renovation, addition, and teardown-rebuild projects rather than greenfield new construction, since undeveloped lots are scarce.
Boston's Inspectional Services Department handles building permits and code enforcement within city limits, and projects in historic districts typically require separate design review before a building permit can be issued, which adds a step most other metros don't have. The dozens of surrounding municipalities that make up Greater Boston each maintain their own independent building departments.

Build vs. Buy in Boston
These two figures aren't directly comparable: the home-value figure includes land and an existing structure, while the build estimate covers construction only — add local land, site work, and financing costs before comparing directly. See our build vs. buy framework for how to weigh the two.
