Thousand Oaks Commercial Vehicle Restrictions Rules (2026): What You Need to Know

The Thousand Oaks Municipal Code, consistent with California Vehicle Code provisions adopted locally, restricts the parking of commercial and oversized vehicles in residential areas of the city. Vehicles that exceed certain size thresholds — including large commercial trucks, box trucks, tractor-trailers, construction equipment haulers, and similar heavy vehicles — are prohibited from parking on city streets in residential zones. The purpose of these restrictions is to protect residential neighborhood character, prevent damage to residential street surfaces from heavy vehicle loads, and preserve sight-line safety at driveways and intersections. The Ventura County Sheriff's Office, which provides law enforcement services to Thousand Oaks under a contract arrangement, is responsible for enforcing vehicle code and municipal parking restrictions throughout the city.

Short-term parking directly associated with active and ongoing loading or unloading operations is generally permitted in residential areas during reasonable business hours. Delivery drivers, contractors, and service vehicles may park on residential streets while conducting active work at a nearby address. However, once the work is complete, leaving a commercial vehicle parked on a residential street — especially overnight — is a violation. Contractors, landscapers, construction workers, and other tradespeople who regularly perform work in Thousand Oaks residential neighborhoods are expected to return their commercial vehicles to a commercial yard, depot, or other non-residential storage location at the end of each work day. Parking a commercial work truck in front of one's own residence in a residential zone overnight is also generally prohibited if the vehicle exceeds the applicable size threshold.

Residents or businesses that have a specific, short-term operational need — such as a large equipment delivery, a moving operation, or a construction project requiring temporary staging — may contact the Ventura County Sheriff's Thousand Oaks station or the city's Community Development Department to inquire about temporary accommodations. Vehicles found in violation of commercial vehicle parking restrictions may be cited under the California Vehicle Code or municipal code, and vehicles posing a traffic hazard or blocking the roadway may be towed at the registered owner's expense.
