Partial 1909 Sanborn Map
Parcel maps for San Anselmo are available online from MarinMap. The Historical Museum has digitized copies of the Sanborn Maps for San Anselmo. Sanborn Fire Insurance Maps are highly detailed city plans providing researchers with a wealth of information about urban change in American cities during the first half of the 20th century. They were created to assist fire insurance companies as they assessed risk associated with insuring a particular property. They were drawn to a scale of 50 feet and show the footprint for buildings (including residences), indicating the type of construction, use of structures, the addresses, and sometimes the names of businesses.
The Sanborn Maps for San Anselmo were created in 1909 and updated in 1919 and 1924 and 1950. Only built-up parts of Town were surveyed so not all streets and areas were included on the maps.
