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

Under Martinez Municipal Code Title 10 and California Vehicle Code Section 22507.5, commercial vehicles exceeding 10,000 pounds gross vehicle weight rating are generally prohibited from parking or standing on residential streets except when actively engaged in loading, unloading, or providing a service (such as construction or deliveries). 'Commercial vehicle' is defined broadly to include trucks, tractors, semi-trailers, construction equipment, tow trucks, and similar vehicles used primarily in the conduct of a business. Storage on residential private property is also regulated through zoning: in most residential zones, only vehicles used by occupants for personal transportation may be parked/stored, and business vehicles above certain sizes must be kept at the business location. Tool trucks, work vans under the weight threshold, and company cars used by residents for personal transportation are generally exempt. In commercial and industrial zones (C-1, C-2, I-P, I-G), commercial vehicle parking is permitted at the business premises subject to site design standards. Truck routes designated under Martinez Municipal Code identify preferred corridors for heavy vehicles, and trucks are prohibited from through-travel on non-truck-route residential streets except for local deliveries. Penalties for violations include citations (typically $75-150) and potential towing under CVC 22651.
