Representative Sean Casten (IL-06) led 16 House Democrats in urging leaders of the real estate industry to provide homebuyers with critical information on the climate risks to which prospective individual home purchases may be exposed. The letter was sent to the CEOs of Zillow, Rocket Companies (Redfin), Compass, and Realtor.com, and asked whether they are committed to providing homebuyers with the best available information on climate-related risks affecting a prospective property.

This is a direct, official record that Casten took concrete action on the claim by sending letters to major real-estate industry leaders asking for upfront climate-risk disclosure to homebuyers.

The letter says that real estate platforms are consumers' first point of contact, that upfront access to comprehensive and trustworthy information is critical, that consumers are increasingly exposed to climate-related risks in the real estate market, and that 'the risk is rarely disclosed to homebuyers at the time of purchase.' It asks Zillow: 'Is your company committed to providing homebuyers with the best available information on the climate-related risks affecting a prospective property?'

This is the clearest primary-source evidence of the requested action: Casten explicitly urged a major industry leader to provide homebuyers with upfront climate-risk information for prospective properties.

Letter to Zillow April 2026

The letter states that failing to provide transparent, actionable information to consumers distorts housing markets and leaves families exposed to escalating costs, and that many homebuyers and renters remain unaware of their exposure because real-estate platforms and MLS systems often do not disclose climate risk. It asks about data sources and how the information is conveyed to prospective homebuyers.

This corroborates that Casten pressed another major listing platform to disclose climate risk information up front to homebuyers and renters.

The letter says cooperation across the housing listing ecosystem in providing ready access to climate risk information is critical, that consumers are increasingly exposed to climate-related risks in the real estate market, and that homebuyers need upfront access to comprehensive and trustworthy information when making major financial decisions.

This provides additional direct proof that Casten pursued the same goal with another real-estate leader, strengthening the record of concrete advocacy rather than a merely rhetorical statement.
