City of Palo Alto Historic Inventory

The City of Palo Alto's Historic Inventory lists noteworthy examples of the work of important individual designers and architectural eras and traditions as well as structures whose background is associated with important events in the history of the city, state, or nation. The Inventory is organized under the following four Categories:

Category 1: An "Exceptional Building" of pre-eminent national or state importance. These buildings are meritorious works of the best architects, outstanding examples of a specific architectural style, or illustrate stylistic development of architecture in the United States. These buildings have had either no exterior modifications or such minor ones that the overall appearance of the building is in its original character.

Category 2: A "Major Building" of regional importance. These buildings are meritorious works of the best architects, outstanding examples of an architectural style, or illustrate stylistic development of architecture in the state or region. A major building may have some exterior modifications, but the original character is retained.

Category 3 or 4: A "Contributing Building" which is a good local example of an architectural style and relates to the character of a neighborhood grouping in scale, materials, proportion or other factors. A contributing building may have had extensive or permanent changes made to the original design, such as inappropriate additions, extensive removal of architectural details, or wooden facades resurfaced in asbestos or stucco.


Historic Resources Board


The Historic Resources Board (HRB) was created by the City Council to assist in the protection and enhancement of Palo Alto's historic structures, properties and districts. The Board is composed of seven members appointed by the City Council, at least three of whom are architects, landscape architects, building designers or other design professionals and at least one member shall possess academic education or practical experience in history or a related field. Regular meetings are at 8:00 a.m. on the first and third Wednesdays of every month and are cablecast live on Government Channel 26.


Professorville Design Guidelines

The City of Palo Alto is in the process of preparing illustrated architectural design guidelines for the Professorville Historic District.  The purpose of the guidelines is to provide a tool to assist homeowners, architects, City staff and the Palo Alto Historic Resources Board in making decisions about how to make alterations, additions, and new construction compatible with the character of the Professorville historic district.
