Westminster, CA Parking Rules: Oversized Vehicle Parking (2026)

The City of Westminster prohibits oversized vehicles on all city streets under Westminster Municipal Code Section 10.44.250 (No parking of large vehicles on all streets - Exceptions). The ordinance bars parking any vehicle that exceeds 84 inches in width, measured at the widest part of the body and excluding mirrors and other extensions, or that exceeds 22 feet in length, or that exceeds 10,000 pounds in weight, on any city street, subject to limited exceptions stated in the code. Because these thresholds capture large box trucks, buses, oversized trailers, and many motorhomes, oversized vehicles cannot be left on Westminster streets even briefly outside those exceptions. The city's code enforcement program explains the policy rationale: heavy vehicles cause residential streets to deteriorate rapidly, and their noise, diesel fumes, and visual bulk degrade neighborhood quality of life. Recreational vehicles face an additional layer of regulation, since they require a 24-hour permit from the Police Department to park on any city street. This citywide size-and-weight restriction is more specific than the California Vehicle Code, which authorizes local authorities to regulate oversized vehicle parking. Owners of large vehicles should arrange off-street or approved storage rather than relying on street parking in Westminster.
