In late 2025, Zillow rolled out its new Listing Access Standards, which basically require that if a listing is being marketed publicly, it must also be available through the MLS so Zillow and Trulia can display it. Zillow has been enforcing this rule across most of the country, but not in the Chicago region covered by Midwest Real Estate Data (MRED).

According to reporting from trusted real estate outlets, that delay is tied to MRED’s unique Private Listing Network (PLN), which is a system that allows agents to share listings internally without making them public.

• Real Estate News explains that Zillow has temporarily paused enforcement in the Chicago area while it works through disagreements with MRED:

• Inman reports that Zillow views private-style networks as potential “hidden listing schemes,” but Zillow hasn’t sent violation notices to the Chicago region while discussions continue:

• HousingWire notes that MRED argues its contract with Zillow requires Zillow to display its licensed listings without restricting them, creating a conflict with Zillow’s new enforcement rules.

• The Real Deal highlights that MRED believes Zillow blocking or limiting access to listings could violate that licensing agreement.

So why isn’t Zillow enforcing the rule yet?

MRED’s Private Listing Network predates Zillow’s new standards, and the two systems don’t align. Zillow wants public-marketed listings to be publicly displayed everywhere. MRED’s PLN allows a listing to be marketed to brokers first and, in some cases, marketed selectively without full public exposure.

The delay seems to come down to:

• contract disagreements,

• concerns about limiting listing visibility,

• and ongoing negotiations about the future of PLN-style systems.

Zillow’s approach elsewhere has been straightforward—non-compliant listings may be blocked from its platform. But in Chicago, Zillow is pausing enforcement while the two sides work things out.

Does the delay change anything for buyers and sellers?

Buyers using Zillow in the Chicago area may not see every property that’s being circulated within the MLS’s Private Listing Network. It’s still possible for homes to be marketed privately to agents before going fully public, and that means some listings may not appear on Zillow right away.

For sellers, it means agents in the Chicago market still have flexibility to choose how and when to publicly market a home. However, any future enforcement from Zillow could eventually change how listings flow from MRED to national portals.

The Zillow–MRED enforcement delay highlights a bigger industry debate about listing transparency and how much control sellers and agents should have over early-stage marketing. For now, Zillow’s Listing Access Standards apply broadly across the country, but Chicago remains a rare exception while both sides negotiate.
