Disclosure Requirement for Residential Real Estate in the Sea Level Rise Exposure Area Flyer

 

 The State of Hawaiʻi enacted a new update to the Mandatory Seller Disclosures in Real Estate Transactions Law in 2021, codified within Hawaiʻi Revised Statutes §508D-15, requiring that real estate transactions within the State of Hawaiʻi must disclose any risk of sea level rise to the property.

Risks to oceanfront properties from shoreline erosion and coastal flooding are increasing with sea level rise as documented in scientific and government studies around Hawaiʻi.
