Several states are advancing mold disclosure 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.
Proposed disclosure requirements vary by state but typically require sellers and landlords to disclose known mold conditions, provide documentation of any mold remediation work performed, and in some cases obtain independent inspection and testing before completing a property transaction.
For restoration contractors, 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. Contractors who follow the standard and maintain thorough records are better positioned to meet disclosure requirements.
