Sonoma, CA Parking Rules: Commercial Vehicle Restrictions (2026)

California Vehicle Code §22507.5 authorizes local agencies to prohibit or restrict parking on any residential-district street of commercial vehicles with a manufacturer's gross vehicle weight rating of 10,000 pounds or more, except when the vehicle is actively making pickups, deliveries or construction-permit deliveries to an address on that street. Sonoma applies this through (1) the general 72-hour on-street parking cap in SMC 10.48.040, which applies to all vehicles including commercial trucks; (2) designated Truck Routes in SMC Chapter 10.60, which require trucks over the posted weight to use only designated routes and prohibit through-truck traffic on non-route residential streets; and (3) SMC 19.40.110, which prohibits use of front, side or rear setbacks of residential lots for storage of inoperable motor vehicles, parts or materials. Commercial loading/unloading is permitted under SMC Chapter 10.48 provisions allowing vehicles engaged in active loading to back to the curb so long as they do not extend past the centerline or block traffic. Off-street commercial parking standards (number of spaces, size, surfacing) are governed by SMC Chapter 19.48 (Parking and Loading Standards), specifically SMC 19.48.030 (general regulations) and 19.48.070 (development standards).
