What is mold and what are a seller's disclosure obligations?

Mold is a fungus that grows in damp conditions and can cause health problems including allergic reactions, asthma attacks, and respiratory infections. While there is no federal law specifically requiring mold disclosure in residential sales, most state disclosure laws require sellers to reveal known material defects that affect health and safety, which includes known mold problems. Real estate agents have an independent duty to disclose known mold. Mold is commonly found after water damage from leaks, floods, or high humidity.
