Controversy and lawsuits
While factors contributing to estimates are described elsewhere, Zillow seemingly overemphasizes home square footage as the major metric driving property valuation.[100] This method may not be unique to Zillow, but unduly distorts value expectations.[101] Listings in areas where land is priced at high premiums often reflect an identical Zillow estimate to that of nearby homes with comparable interior square footage, but where the home might be decades older. Condition, age of home, special features, and proximity to nuisances are insufficiently factored into the estimate. Zillow has made some effort to add balance by including an option for owners to provide their own value estimate, but these figures can be similarly unreliable as being opinion instead of quantifiable.
In 2014, Zillow faced several lawsuits from former employees at the Zillow operation in Irvine, California, alleging violations of California Labor Code and California Business and Professions Code.[102] On February 26, 2016, the U.S. District Court for the Central District of California certified the class to include anyone who worked as an inside sales consultant at Zillow between November 2010 and January 2015.[103] Among the numerous allegations brought by high-profile attorneys Bobby Samini and Mark Geragos, Zillow is accused of failing to pay wages, failing to pay overtime pay, and failing to provide meal and rest breaks. Zillow responded: "the narrative being pushed by this law firm through their multiple lawsuits is completely inconsistent with those who know and work with Zillow...the behavior described does not accurately depict our culture or the 1,200 Zillow employees."[104]
In addition, Samini and Geragos represented a former Zillow employee in a sexual harassment action against the company, alleging "sexual torture"[105] and "the most heinous acts of sexual harassment imaginable".[106] According to the lawsuit, Zillow's Southern California office represents an "adult frat house where sexual harassment and misconduct are normalized, condoned, and promoted by male managers."[105] Based on the allegations against the company, Samini has called Zillow a "modern day Animal House."[107] On May 5, 2016, Zillow settled the action for an undisclosed amount, without admitting any wrongdoing.[108]
In 2017, Zillow sent a cease-and-desist letter to Kate Wagner, the author of McMansion Hell, a blog that lampooned the presentations of luxury homes found on the site.[109][110] Wagner was represented by the Electronic Frontier Foundation. Zillow later released a statement saying it had "decided against moving forward with legal action" on the matter.[111]
In June 2025, the real estate brokerage, Compass, Inc., sued Zillow, alleging that Zillow violated federal antitrust laws with its policy that any home that was put on the market but not available for listing on Zillow within 24 hours would be forever banned from its site. The Zillow policy seemed to target Compass' "Private Exclusives" marketing channel, in which about 7,000 home listings were temporarily available only to Compass agents and the buyers working with them.[112][113]
In September 2025, a proposed class action lawsuit was filed against Zillow in Seattle, alleging that Zillow violated federal real estate law as well as a Washington state consumer protection law by misleading prospective home buyers into contacting real estate agents affiliated with the company, from whom Zillow takes up to 40% of the commissions agents earn, rather than the agent who listed a home for sale.[114][115]
In 2025, Virginia, Connecticut, Arizona, New York State and Washington State sued Zillow alleging that Zillow paying Redfin "$100 million to cease competing for multifamily housing listings, terminate its existing multifamily advertising contracts, and transition its customers to Zillow" violated federal antitrust law.[116][117]
