Maps are a great way to see not only the history of your house, but of your neighborhood, city, and county! You can use maps to see physical changes to your house and land, see how highways and roads developed, locations of businesses long closed, and lots more. They’re a great way to understand the context of your house over the years.
Maps are a necessary component to any house history research, but actually finding historical maps can be a little tricky. Luckily, archives and historical societies have taken the time to digitize hundreds of historical maps and make them available online– you just have to know where to look.
I’ve put together a resource list of 30+ websites where you can find historical maps for California. These maps include county boundaries, highways, city maps, fire insurance maps (the holy grail), and neighborhood maps. And they’re all free to use!
