PrimeMLS is continuing efforts to become RESO Compliant. RESO is the Real Estate Standards Organization, an independent body formed to develop data standards and processes that create efficiencies for all participants in real estate transactions, focusing on streamlining data for all.


What does this mean for PrimeMLS?

To achieve this data standardization, certain adjustments are made, including renaming or reorganizing fields, removing fields, or transferring selections within a field to a different one. These changes will impact both the search and listing input/maintenance modules. These modifications are essential for ensuring consistency and compatibility across different systems and platforms.


When will these changes take place?

Round 3 of RESO updates will occur on July 8, 2025.


Reports in Paragon Connect and Paragon Professional, as well as the listing input forms (located in the MLS Documents section of Paragon), will be updated in accordance with the changes highlighted in each round. 


This latest round of updates is a big one with over 300 changes to field names and selections as part of our ongoing RESO compliance work. Most of these are minor, consistency-driven adjustments. For instance, "Attic - Finished" is now "Finished Attic" and "Date - MLS List" has been revised to "MLS List Date."


While every updated field is noted in the documentation, not every individual selection within each field is listed. Once you dive in, you'll get the idea. Because of the volume of changes, we've skipped including a chart here. Instead, the changes are compiled into a single document for easy review.
