Public parking is located in the garage on Third Street between Santa Rosa Avenue and D Street. Remember to take your parking ticket with you so that you can pay for parking when you leave; rates are 75 cents per hour.

The City of Santa Rosa’s reunification of Courthouse Square project will be intensifying in August 2016. The section of Mendocino Avenue that connects to Santa Rosa Avenue (Old Courthouse Square) will be permanently closed starting August 5th. If you are accessing our offices on a north-south route, you are encouraged to use Highway 101 as the primary route rather than Mendocino Avenue or Santa Rosa Avenue. Please see the City’s website for more information. Please also note that the pedestrian access located at the western front of our building at 50 Old Courthouse Square is still open, but the access is now bordered by construction fencing.
