Sanborn Fire Insurance Maps are detailed maps showing building footprints, construction materials, width of streets, house addresses, and the use of the building. The Map Room has Sanborn maps for cities in Santa Cruz, Monterey, San Benito, Santa Clara, and San Mateo counties from various years.
Our digital map collection includes over 1200 digitized Sanborn slides of Santa Cruz county. To limit your results to Sanborn maps, search on a street name or feature and append "and Sanborn". For example, search on "Branciforte and Sanborn", or "jail and Sanborn".
Zoom in using the plus button or the slider bar at the top; drag the pink box on the tiny map at the upper left to re-position within the map.
Only slides dated prior to 1923 may be digitized due to copyright restrictions.
The bulk of the Map Room's Sanborn collection is 2" x 2" color slides. The slides can be copied in black and white. The hardbound editions may not be copied.
