State Laws and Rights

Vermont mold law snapshot

Vermont does not have a mold-specific statute, but habitability rules still apply.

Vermont recognizes an implied warranty of habitability for all residential rentals under 9 V.S.A. 4457. Landlords are required to deliver and maintain premises that are safe, clean, and fit for human habitation throughout the entire tenancy. This warranty cannot be waived by any provision in the rental agreement, and any such waiver is deemed contrary to public policy and unenforceable. The warranty covers all latent and patent defects in essential facilities vital to residential use, including issues like mold that may render premises unsafe or unsanitary. The 1984 Vermont Supreme Court decision in Hilder v. St. Peter established that tenants can seek reimbursement of rent paid and additional damages without needing to abandon the premises when the warranty is breached.
