Boston permits — week of 2026-05-18
A single permit at 421 Park Drive accounts for $438 million — nearly three-quarters of Boston's entire declared construction value this week, and it's filed as a new erection, not a renovation. That kind of valuation on a ground-up build is rare enough to anchor the whole conversation. Elsewhere, the Seaport and Back Bay are seeing serious interior overhaul money move through the system, with five renovations across the top ten clearing a combined $68 million.
