Several states are advancing legislation in 2026 that would require sellers and landlords to disclose known mold conditions in residential properties, creating new documentation requirements for restoration contractors and property owners.
The legislative trend reflects growing consumer awareness of the health risks associated with mold exposure and increasing pressure on state legislatures to provide stronger protections for homebuyers and renters.
For restoration contractors, stronger mold disclosure requirements create both opportunities and obligations. Contractors who perform mold remediation work may be asked to provide documentation that is used in real estate transactions, and the accuracy and completeness of that documentation can have significant legal implications.
The IICRC S520 standard provides a framework for mold remediation documentation that is increasingly being referenced in state disclosure requirements and real estate transactions. Contractors who follow the standard and maintain thorough records are better positioned to meet disclosure requirements.
Industry observers note that the trend toward stronger mold disclosure requirements is likely to continue, driven by increasing public awareness of mold health risks and the growing body of scientific evidence linking mold exposure to serious health conditions.
