What this page counts—and what it does not

Latest canonical record update in this view: July 8, 2026.

Canonical base

SpanVor's canonical property table, filtered to Arizona, 2 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.
