State Laws and Rights

Indiana mold law snapshot

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

Indiana Code 32-31-8-5 establishes the implied warranty of habitability, requiring landlords to deliver rental premises in a safe, clean, and habitable condition. Landlords must comply with all applicable health and housing codes, maintain common areas in a clean and proper condition, and provide and maintain electrical systems, plumbing systems with adequate hot and cold running water, sanitary systems, and HVAC systems with adequate heat. This warranty cannot be waived by contract. The Indiana Supreme Court affirmed these protections in Rainbow Realty Group, Inc. v. Carter (2019), holding that landlords cannot contract around habitability requirements.
