Department of Revenue Issues Emergency Rule Blocking Zillow, Redfin Access in Medina After Detecting 'Suspicious Browsing Activity'

Bellevue Chamber of Commerce  |  April 1, 2026

OLYMPIA — The Washington State Department of Revenue (DOR) issued an emergency rule late Tuesday temporarily blocking access to Zillow and Redfin in Medina and several nearby Points communities after detecting what officials described as, "highly irregular and coordinated browsing behavior."

According to DOR, the action follows a sudden surge in online activity tied to luxury home listings — many exceeding $5 million — that appeared within hours of the close of the most recent legislative session.

"We observed a statistically significant spike in listing activity concentrated in a very small number of zip codes," said a DOR spokesperson. "From a pattern-recognition standpoint, it did not appear ... organic."

Officials declined to speculate on potential causes, but confirmed that internal monitoring flagged repeated searches involving terms such as "no state income tax," "residency requirements," and "how long do you have to live in Nevada?"

Out-of-State Activity Raises Questions

Further complicating matters, DOR analysts reported that a meaningful share of the browsing and listing activity originated from IP addresses outside Washington state.

"We're seeing clusters of activity from locations like Sun Valley, Scottsdale, and — interestingly — boats. That raises legitimate questions about whether this is standard market behavior or something more coordinated." — DOR Spokesperson

State officials emphasized that, at this time, they are treating the situation as a potential cybersecurity issue.

"When you see this many high-value properties come online simultaneously, you have to consider the possibility of malware or a coordinated attack," said one official. "There's no obvious policy explanation that would cause this kind of behavior all at once."

Market Disruptions Felt Locally

The emergency rule has temporarily cut off access to major Multiple Listing Service (MLS)-connected platforms, frustrating local real estate professionals and their clients.

"This has been incredibly disruptive," said a broker with Compass Realty, who asked not to be named due to ongoing client sensitivity. "A number of our clients were preparing to list, and now they can't even check comparables."

According to the broker, several homeowners attempted to pivot to off-market, private listings, only to encounter additional complications.

"They were told that practice was effectively prohibited under legislation passed last session," she said. "So, now they're in a position where they can't list publicly, and they can't list privately. It's ... a tight market."

Officials Urge Calm

Despite the disruption, DOR is urging residents to remain calm while the situation is reviewed.

"We are confident this is either a technical anomaly or some form of external interference," the spokesperson said. "We do not currently have evidence to suggest this reflects any kind of broader behavioral shift."

In the meantime, access to Zillow and Redfin in the affected areas will remain restricted pending further analysis.

Officials noted that normal activity is expected to resume once browsing patterns return to what they described as "historically stationary conditions."
