The method stays attached to the market signal.

County assessor and land records arrive with different identifiers, addresses, building conventions, and update cycles. SpanVor normalizes those records into a canonical industrial-property universe, resolves duplicate source representations, and preserves source provenance.

• A property must satisfy the industrial-universe classification contract; a marketing label alone does not qualify it.
• Building area, lot area, year built, assessed value, and other ordinary facts are retained only when a source supplies a usable value.
• Missing values stay blank. They are excluded from medians and coverage calculations instead of being silently estimated.
• Public property pages use explicit field allowlists. Adding a new source column does not make it public by default.

Supply begins with official planning, zoning, permit, inspection, occupancy, and development records. One real project may create many records across authorities, phases, revisions, addresses, and dates. SpanVor links corroborating events to a parent project and prevents those supporting events from becoming additive projects.

Discovery record

Evidence that a possible industrial or self-storage project exists. It may still need local corroboration and does not automatically carry a lifecycle claim.

Project record

A reconciled project or opportunity with a stated asset family, stage, time signal, and evidence basis.

Lifecycle

Planning, approval, construction, inspection, occupancy, completion, or another explicitly supported stage. A later record may revise an earlier stage.

Verified lower bound

The visible total from connected, producing source lanes. It is not a claim that every authority or project in the market has been captured.

Demand intelligence tracks evidence that can create or concentrate industrial demand: planned housing, active residential permits, employers, retail, schools, healthcare, infrastructure, and other locally relevant drivers.

• Planned homes or lots describe stated future capacity; they are not the same as active permitted units.
• Permit and construction activity describes observed velocity at the time of the release.
• Annual Census or other market benchmarks calibrate source coverage. They are never added to project totals.
• Named drivers, parties, exact locations, and source records are premium detail. Public pages receive safe categories, counts, and approximate geography.

Public spatial discovery is intentionally coarser than Pro. Aggregate property cells suppress groups smaller than five, public map exploration stays below zoom 10, and public Supply/Demand coordinates are rounded to approximately 0.02 degrees. Pro access is rechecked server-side before exact points or close zoom are returned.

Every Phase 4 Supply and Demand map is paired with a complete searchable list or table from the same record universe, including records that cannot be mapped. The national property Map and List share the same filter and selection state.

A market becomes discoverable only when its release manifest records explicit approval and the website verifies market identity, state membership, freshness, path containment, regular-file status, and exact Supply and Demand artifact hashes.

Current

The approved release is within its stated review window and its artifacts still match the approved hashes.

Last known good

A previously approved release may remain visible with a stale warning only when its contract explicitly allows that posture.

Withheld

Missing, unapproved, stale without permission, path-unsafe, identity-mismatched, or hash-mismatched releases do not enter navigation or the canonical sitemap.

Correction

A material error is recorded, corrected at its source or presentation layer, and listed on the corrections page when it affected published interpretation.

SpanVor scores and classifications organize large property universes for investigation. They are signals based on available fields and documented rules—not appraisals, broker opinions of value, investment recommendations, vacancy estimates, or promises that an owner will sell.
