reference · Scope: business · Status: current

Created 2026-06-21

Summary

Claim. The Property resource in RESO DD 2.0 contains 652 fields, organised into 13 named groups: Business, Characteristics, Equipment, Farming, Financial, HOA, Listing, Location, OccupantOwner, Structure, Tax, UnitTypes, Utilities.

Source. dd.reso.org/DD2.0/Property/ ("Property … 652 fields"); ddwiki.reso.org/display/DDW20/Property+Resource, accessed 2026-06-21.

Confidence. Verified. Standards-body primary source.

Caveats. Field-count by group is RESO's grouping convention; the same fields may legitimately be re-grouped in board implementations. Use as headline architecture, not as a database schema you can copy.

Implication / use. Drives the "even one resource is too big to use" framing. A typical agent touches dozens of fields out of 652 in the Property resource alone.
