Longmont FAQ
Can I park on my front lawn in Longmont?
No. Title 15 of the Longmont Land Development Code (Chapter 15.05) requires that vehicles in front and side yards facing city streets be parked on a surface of asphalt, concrete, or gravel. Parking on grass, bare dirt, or landscaped areas is a violation enforced by Code Enforcement and Planning & Development Services (303-651-8330). Property owners typically receive a notice with a deadline to move the vehicle and, if needed, install a code-compliant surface.
Do I need a permit to widen my Longmont driveway?
Yes, where the work touches the public right-of-way. New or modified driveway approaches and curb cuts in the city right-of-way require a permit from Longmont Public Works & Natural Resources, which inspects the work against city construction standards. The on-lot driveway expansion itself is governed by the Land Development Code, which limits the allowable parking-surface area in a front yard. Contact Planning & Development Services at 303-651-8330 before starting work.
