Longmont, CO Parking Rules: Curb Color Rules (2026)

Longmont follows the standard Colorado practice that all official curb markings on public streets - red (no parking / fire lane), yellow (loading zone), green (time-limited parking), white (passenger loading), and blue (accessible parking) - are placed by city Transportation or Parking Enforcement under LMC Title 11 and Title 13 (Streets, Sidewalks & Public Places). Residents and adjacent property owners may not paint, repaint, or alter a public curb; the city has not adopted a permit program for private red-curb requests in front of driveways. Even where curb paint has faded or is unmarked, the underlying state-law no-parking distances incorporated into LMC Title 11 still apply, including: no parking within 15 feet of a fire hydrant (CRS 42-4-1204(1)(h)), no parking within an intersection or crosswalk, and no parking within 20 feet of a crosswalk at an intersection. Blocking a fire hydrant or fire lane is one of Longmont's enumerated immediate-tow conditions. To report missing or faded curb markings, contact city Public Works & Natural Resources; for marked-curb violations, call Parking Enforcement at 303-651-8663. Unauthorized painting of a public curb is enforced under Title 13's prohibitions on damaging or defacing city right-of-way property; the city can require restoration at the property owner's expense and assess civil penalties.
