Downtown parking is available at two public parking lots, at no charge. The largest is the Casa Grande lot, located behind the historic Barracks just north of the Plaza, with an entrance off First St. East. There is a smaller public parking lot behind Sebastiani Theatre, with an entrance off East Napa St. This lot includes designated parking for electric vehicles with charging stations. Follow the signs around the Plaza.
On-street parking in Sonoma is also free, but some areas have time limits or residential permit requirements, so look for signage. Street parking in the Plaza area is limited to 3 hours. To take your time and avoid a ticket, park in the public lots whenever possible.
