There is a possibility that the City of Santa Rosa might have a “plot plan” of your property (or other historic building permit information) in City Building Permit records from when the houses were first constructed. These are housed in the Planning and Economic Development Department in Room 3 at City Hall (100 Santa Rosa Avenue, Santa Rosa). But they are not quick and easy to access, and it takes about 10 days to get your hands on them since it means digging through archives and microfilm to find them. You can request via mail and save yourself a trip downtown.
To find out what information the City might have about your property, the owner will need to complete the City’s “Public Copy Request Form” and submit it to the City’s Planning & Economic Development Department via hand delivery or mail to this address:
Planning & Economic Development
Attn: Copy Requests
100 Santa Rosa Avenue, Room 3
Santa Rosa, CA 95404
