A Historic Resources Inventory (HRI) is a listing of structures or sites that contribute to the history or character of a region.

The information on each form varies by each region and the person conducting the inventory; however, forms normally include architectural notes, approximate age, and a photograph.

Within Napa County several HRIs have been compiled: Napa City, Yountville, St. Helena, Calistoga, and Unincorporated Areas. These forms are important for documenting the historic character of Napa County, and can be a great aid in researching the history of a property. Most forms are listed by street address, while some older structures and sites are described by neighboring streets or landmarks.
