Full Breakdown
Simi Valley's commercial-vehicle parking rules combine two sources. First, the City of Simi Valley's published Oversized Vehicle & Trailer Parking Restrictions flyer applies the same 23 ft / 7 ft / 8 ft dimensional limits of SVMC Section 4-9.402 to commercial trucks, box trucks, and trailers as it does to RVs; they are prohibited from all city streets and violators are cited and may be towed at the owner's expense. Detached trailers (utility, work, equipment) are likewise barred from on-street parking. Second, Simi Valley's home-occupation rules in the Development Code (Title 9) prohibit a home-based business from causing the overnight parking of commercial vehicles with a gross vehicle weight of 10,000 pounds or greater within the residential area in which the home occupation occurs. Bona-fide visitors or contractors with oversized commercial vehicles must obtain a temporary permit from the Simi Valley Police Department Traffic Bureau prior to street-parking.
Violations & Fines
Citation under SVMC 4-9.402 and towing at the owner's expense. Home-occupation violations are pursued separately through Code Enforcement under SVMC Title 9.
