Longmont, CO Parking Rules: Oversized Vehicle Parking (2026)

Longmont does not maintain a separate length- or weight-based oversized-vehicle ordinance for ordinary trucks, but it does single out 'sleeper vehicles' for the strictest treatment. Under LMC Chapter 11.12, a sleeper vehicle - defined as a camper coach, camper trailer, motor home, multi-purpose trailer, trailer coach, or recreational vehicle, including any vehicle converted to serve as temporary living or sleeping accommodation - may not be parked on a public street, alley, or right-of-way without a permit. Permits are $25 for 7 days, capped at four per vehicle per calendar year, with no back-to-back issuance and a 7-day cooldown after expiration. For other oversized vehicles (box trucks, flatbed trailers, dump trucks, semis), the universal LMC Chapter 11.12 rules apply: 48 hours in one location, then a required 600-foot move with a seven-day no-return restriction; no blocking of driveways, fire hydrants, fire lanes, or alleys; no parking in posted no-parking zones; and no parking in a way that obstructs travel lanes or sight distance. Contractor trailers used during active repairs or alterations may remain on the street up to 180 days with a posted dated notice listing the job-site address and contact info. On private property, oversized vehicle storage is subject to the Land Development Code (Title 15), which requires a paved or graveled surface and limits front-yard parking, and to any applicable HOA covenants. Longmont Code Enforcement (303-651-8695) responds to complaint-based reports of oversized vehicles in residential neighborhoods.
