Summary

Street parking on County roads in unincorporated Sonoma County is governed by Sonoma County Code Chapter 18, Article III. Parking is generally allowed except where signs or curb paint prohibit it, near intersections and traffic controls, within six feet of the road center, and where the Board of Supervisors has designated no-parking or time-limited zones by resolution.

City-specific rules exist: Santa Rosa, and Petaluma have their own street parking limits rules that differ from Sonoma County's county-level regulations. If you live in one of those cities, check the city-specific page instead.

No person who owns or has possession, custody or control of any vehicle shall park such vehicle upon any street, roadway or parking lot for more than a consecutive period of seventy-two (72) hours.

Full Breakdown

Sonoma County Code Sec. 2 sets the general 'No Parking Areas' for County roads in the unincorporated area. No person may stop, park, or leave a vehicle standing within a divisional island, in any signed or red-curb no-parking area, on a railway track, anywhere parking would create a traffic hazard, within 20 feet of a crosswalk at an intersection (where signed or red-painted), within 20 feet of the approach to a traffic signal or stop sign, or within six feet of the center of any road whether or not a centerline is painted.

Sec. unless otherwise posted). Sec. 5 authorizes the Board of Supervisors to establish 'No Parking' and 'No Overnight Parking' zones by resolution, effective only once signs or curb markings are in place. The Public Works Director (Sonoma Public Infrastructure) maintains and posts the official list of restricted-parking roads. Where time limits or zones are not posted, ordinary street parking is generally permitted, subject to the 72-hour maximum in Sec. 7 and the oversized-vehicle limits in Sec. 10.

Violations & Fines

Parking contrary to posted signs, curb paint, or a Board resolution is a parking violation processed as a civil penalty under California Vehicle Code Sec. 40200 et seq., with the penalty schedule set by Board of Supervisors resolution per Sec. 18-3.6. Vehicles parked in violation are subject to removal.

Frequently Asked Questions

Where can't I park on a County road?
Sec. 18-3.2 bars parking within six feet of the road center, within 20 feet of a crosswalk at an intersection or the approach to a stop sign or signal where signed, in any red-curb or signed no-parking area, on divisional islands, and anywhere that would create a traffic hazard. Other posted time limits and zones apply where signs are present.
Are there time limits on County street parking?
Only where posted. Sec. 18-3.3 lets the County set 15-minute, 30-minute, one-hour, or two-hour limits, generally effective 9:00 a.m. to 6:00 p.m., and the Board of Supervisors can add no-parking or no-overnight zones by resolution. Limits take effect only once signs or curb markings are installed.
