Violations may also be submitted by email. Additional details in the form of PDFs, photos, and screenshots are extremely helpful and can be sent to [email protected]

The name of the person reporting the violation will not be disclosed whether it is reported to the hotline, email, or both.


The MLS Clear Cooperation Policy (also known as NAR Policy 8) mandated by the National Association of REALTORS® was incorporated into the Columbus REALTORS MLS Rules & Regulations as Section 1.01 Clear Cooperation, effective May 1, 2020.

Section 1.01 - Clear Cooperation

"Within one (1) business day of marketing a property to the public, the listing broker must submit the listing to the MLS for cooperation with other MLS participants. Public marketing includes, but is not limited to, flyers displayed in windows, yard signs, digital marketing on public facing websites, brokerage website displays (including IDX and VOW), digital communications marketing (email blasts), multi-brokerage listing sharing networks, and applications available to the general public."
