Zillow Removes Climate Risk Data After Realtor Backlash
▼ Summary
– Zillow removed climate risk scores from over 1 million listings after real estate agents complained the data was causing lost sales.
– The scores, added in September 2024, were provided by First Street, a startup whose data remains on sites like Realtor.com and Redfin.
– Real estate agents, including the CEO of CRMLS, argued the scores negatively impacted property desirability and questioned their accuracy.
– First Street defended its models as transparent and peer-reviewed, citing their accuracy in predicting Los Angeles wildfire damage.
– The removal highlights a tension between consumer access to climate risk data and industry resistance, despite growing investor and insurer reliance on such information.
For those navigating the complex journey of purchasing a home, access to transparent environmental data has become a critical factor. Zillow recently removed climate risk scores from over a million property listings, a significant reversal after introducing the feature just over a year ago. The decision came in direct response to complaints from real estate professionals, particularly the California Regional Multiple Listing Service (CRMLS), who argued the prominently displayed information was negatively impacting sales.
The climate risk data, supplied by analytics firm First Street, assessed factors like flood and wildfire probability. Zillow had initially integrated these scores, citing research that a vast majority of buyers consider such risks. Following the backlash, the platform replaced the explicit scores with a more subtle link to First Street’s records. A spokesperson for First Street, Matthew Eby, emphasized the consequence of this shift, stating that without clear pre-purchase information, the financial risk simply transfers to become a post-purchase liability for the homeowner.
This data remains visible on other major real estate platforms, including Realtor.com, Redfin, and Homes.com. First Street, which has secured substantial funding from notable investors, stands by its methodology. The company asserts its models rely on transparent, peer-reviewed science and point to their accurate predictions during events like the Los Angeles wildfires as validation.
The core of the dispute lies in the perceived impact and accuracy of the information. CRMLS CEO Art Carter expressed concern that displaying specific flood probabilities could dramatically alter a property’s desirability. He also questioned the data’s precision for areas with no recent history of flooding. This sentiment echoes previous agent complaints that such scores unnecessarily introduce doubt into buyers’ minds.
This tension highlights a broader clash between market transparency and sales facilitation. Official hazard maps, often criticized for being outdated, may underestimate true risk, leaving homeowners unprepared. As climate change intensifies weather-related threats, the real estate and insurance industries are grappling with how to accurately price and communicate these dangers. Investors and insurers are increasingly relying on data from firms like First Street to assess long-term viability and risk.
While these stakeholders will continue to use advanced climate analytics, the removal of scores from Zillow represents a setback for consumer access. The platform had briefly helped democratize information, allowing everyday buyers to perform due diligence with the same tools available to institutions. Now, obtaining that crucial insight requires an extra step, placing the burden of research more firmly on the consumer in an already asymmetric marketplace.
