Real Property Law Section 231-B Amendment: Mandatory Flood Provisions in Proprietary Leases

November 7, 2023

Real Property Law Section 231-B has been amended, effective immediately, to require that every existing and prospective residential lease provide a notice to the tenant with respect to the leased premises advising the tenant of the following:

  • Partial or full inclusion in a FEMA designated flood plain;
  • Partial or full inclusion in a Special Flood Hazard Area;
  • Partial or full inclusion in a moderate risk flood hazard area; and
  • Flood history and current flood risk arising from natural events such as heavy rain fall, coastal surges, tidal inundation or river over flows.

The law does not relate to flooding due to broken pipes or bathroom leaks, etc.

The statute’s reference to residential leases includes proprietary leases between cooperative apartment corporation’s and their shareholders, subleases between shareholder’s and their subtenants as well as leases between unit owners in condominium and HOAs and their tenants.

The requisite notice must also apprise the lessee/tenant of the availability of flood insurance and limitations of typical policies which typically do not cover flood damage.

The rationale behind this legislation is to increase public awareness of the risk of flood damage and availability of insurance so as to encourage tenants to procure adequate protection.
