Rent abatement is a legal remedy that allows tenants to reduce or withhold rent when their rental unit becomes partially or fully uninhabitable due to the landlord’s failure to maintain safe and livable conditions. Common reasons include lack of heat, water damage, pest infestations, or structural hazards. In New York City, rent abatement protects tenants under the warranty of habitability and can be pursued through negotiation or housing court. Tenants must document issues and notify the landlord before seeking relief. Understanding your rights to rent abatement ensures you’re not paying full rent for a space that fails basic living standards.
