If a landlord breaches the warranty of habitability, the tenant may sue for a rent reduction. Alternatively, rent regulated tenants can also file a rent reduction complaint with DHCR. The tenant may also withhold rent, but in response, the landlord may sue the tenant for non-payment of rent. In such case, the tenant may countersue for breach of the warranty.
