The collection documents Historic Environment Consultants' work on projects needing historic preservation evaluation, including historic districts, preservation districts, areas under development or redevelopment, and individual houses and buildings. Properties include commercial, city, county, state, and federal buildings and properties; industrial and agricultural areas; and private homes. About two-thirds of the collection documents properties within the city limits of Sacramento; the rest documents properties in Sacramento County and Northern California, with a few properties in Southern California and Nevada.

Historic Environment Consultants was founded in Sacramento in 1977 by architectural historian Paula Boghosian, who has been the principal consultant for the life of the company. The firm has helped preserve historical buildings, districts, and cultural resources throughout the state, but mainly focused on Sacramento and the Sacramento area.
