Summary
The City of Sonoma has no separate on-street bike lane ordinance; instead, Sonoma Municipal Code § 10.74.010 regulates how bicycles and similar conveyances may be ridden on the city's sidewalks and pedestrian/bicycle paths, banning unsafe speeds citywide and barring bikes entirely from the sidewalks that ring the historic downtown Plaza.
It is unlawful for any person to ride, use, or operate a bicycle or other conveyance propelled by human or motor power, including roller skates, a skateboard, coaster, scooter, tricycle, or other similar device any place in the city upon a sidewalk, or pedestrian or bicycle path, at a speed greater than is reasonable or prudent having due regard for weather, visibility, traffic, width of sidewalk or path, or at a speed or in such a manner which endangers the safety of persons or property. ... It is unlawful for any person to ride, use, or operate a bicycle or other conveyance propelled by human or motor power identified in subsection (B) of this section, upon the sidewalks in the downtown Plaza area, specifically the public sidewalks on both sides of First Street West between Spain Street and Napa Street, First Street East between Spain Street and Napa Street, Napa Street between First Street East and First Street West, and Spain Street between First Street East and First Street West.

Full Breakdown
010(A) generally permits riding a bicycle or human-powered conveyance, including roller skates, skateboards and scooters, on any public sidewalk or pedestrian/bicycle path in the city. Subsection (B) then bars riding at "a speed greater than is reasonable or prudent having due regard for weather, visibility, traffic, width of sidewalk or path," or in a manner endangering people or property, and says riders should yield to pedestrians when reasonable. Subsection (C) imposes a full ban in the historic core: it is unlawful to ride on "the public sidewalks on both sides of First Street West between Spain Street and Napa Street, First Street East between Spain Street and Napa Street, Napa Street between First Street East and First Street West, and Spain Street between First Street East and First Street West," the sidewalks bordering Sonoma Plaza.
011, which exempts a "motorized bicycle" (pedals plus a motor of 1,000 watts or less, capped at 20 mph) and a "motorized scooter" (a stand-up device with a motor of 1,000 watts or less, capped at 15 mph), along with disability wheelchairs/tricycles and battery-powered children's toys. City personnel are exempt under subsection (F). Current through Ordinance 13-2025, passed December 3, 2025.
Violations & Fines
Section 10.74.010(E) makes any violation an infraction and separately declares the conveyance itself a public nuisance, which "may be summarily abated by any peace officer... by seizure and impoundment," with the seized bicycle, skateboard or scooter held for disposition as ordered by the court hearing the case.
