What this page counts—and what it does not
Latest canonical record update in this view: July 15, 2026.
Canonical base
SpanVor's canonical property table, filtered to Massachusetts, 5 audited county GEOIDs, the small-bay industrial class, and non-duplicate map records.
Inventory, not availability
The total is a tracked public-record universe—not a count of buildings for sale, for lease, vacant, or currently marketed.
Measured fields only
Building area uses 100–199,999 SF and vintage uses plausible recorded years. Missing values are excluded, never filled.
Release gates
County totals must reconcile, size and vintage coverage must clear the publication floor, and all 12 property links must pass the stricter trailhead gate.
