NEW YORK — Commercial property owners are facing a growing number of mold-related lawsuits from tenants in 2026, as awareness of mold's health effects increases and courts in several states increasingly hold landlords liable for failing to maintain mold-free conditions in leased premises.
The legal theory in most mold liability cases is breach of the implied warranty of habitability — the legal requirement that landlords maintain rental properties in a condition fit for human occupancy. Courts in California, New York, Texas, and Florida have all issued significant mold liability verdicts in recent years, with awards ranging from tens of thousands to millions of dollars.
Commercial tenants — including office tenants, retail tenants, and industrial tenants — are increasingly including mold inspection and remediation clauses in their lease agreements, requiring landlords to inspect for mold at specified intervals and to remediate any mold found within a specified timeframe.
Property managers who respond promptly to mold complaints, document their response, and retain qualified remediation contractors are significantly less likely to face successful mold liability claims. The key is documentation — property managers who can demonstrate that they responded appropriately to a mold complaint are in a much stronger legal position than those who cannot.
Restoration contractors who work with commercial property managers should understand the legal context of their work and provide documentation that supports the property manager's defense in the event of a tenant lawsuit. This includes detailed scope of work documentation, post-remediation verification test results, and records of all communications with the property manager regarding the remediation.
