The George A. Applegarth Collection focuses on the construction of Clyde, California, a residential and commercial development for the Pacific Coast Shipbuilding Company. The collection is important for documenting both the planning and growth of company towns and the construction of low cost housing. The collection contains no personal papers, and very few papers on other projects in San Francisco.

Series I. Town of Clyde is the largest series in the collection. It includes the files of the project, specifications, photographs, and drawings. The files include correspondence between Applegarth, Maybeck, and the Clyde Company, which was the subsidiary of the Pacific Coast Shipbuilding Company responsible for the construction of the town. The series documents the planning of the town and the construction of the hotel and residences. The drawings include blueprints for commercial buildings that were unbuilt.

Series II. Additional Donations contains photographs of the Clyde Hotel taken after the building was no longer in use; drawings of an Applegarth commercial project located at Two Pine Street, San Francisco; one blueprint of the California Palace of the Legion of Honor; drawings of the Bemiss building in San Francisco; and a commercial project for Davis, Winfield Scott in San Francisco.
