Historic Resources Inventory The Historic Resources Inventory (HRI) is a database containing building descriptions and evaluations of potential historic resources in Santa Monica. Each property listed on the HRI has been evaluated by professionals using accepted industry standards and criteria. City staff uses the HRI to identify properties of potential historic significance. The Historic Resources Inventory is currently undergoing a comprehensive citywide update. Please visit the HRI Update page for more information. Check Property Status Properties listed in the HRI will return a data sheet including an evaluation code. In accordance with Chapter 9.33, sellers are required by law to disclose to buyers whether their property is listed in the HRI or is a designated Historic Resource. Data sheets in the HRI currently reflect information from the 2008-2010 citywide update. City staff is working to include datasheets from earlier surveys. If your property is not included in the HRI or for additional help you are encouraged to Contact Us for more information.
