In Longmont, Colorado, businesses and property owners must follow the city sign regulations before placing permanent signs or temporary sidewalk/A-frame signs in the public right-of-way or on private property. This guide explains the permit process, common sidewalk sign rules, enforcement pathways, and action steps to apply, comply, or appeal.

Overview

Sign permits in Longmont are administered by the city planning and building departments. Rules cover location, size, anchoring, illumination, and placement relative to sidewalks, curb cuts, and clear pedestrian paths. Sidewalk or "A-frame" signs often have specific requirements to preserve an accessible pedestrian route and avoid traffic sightline obstructions.

Check the Development Services sign guidance before ordering a sign.

Sidewalk Sign Rules (Typical Requirements)

  • Permit required: Many sidewalk signs require a sign permit or a sidewalk sign authorization.
  • Placement: Signs must not block a minimum clear path for pedestrians (often 48 inches, but confirm with city rules).
  • Anchoring and stability: Signs must be weighted or secured to prevent tipping in wind.
  • Location limits: Signs may be restricted near curb cuts, intersections, transit stops, or ADA ramps.
  • Time and display: The city may limit hours of display or seasonal use for temporary signs.
Sidewalk signs must preserve an accessible pedestrian route.

Penalties & Enforcement

Enforcement is handled by the City of Longmont through Development Services, Code Enforcement, or Building Inspection divisions depending on the violation type. The municipal code or enforcement policies specify the remedies and procedures.

  • Fines: Specific fine amounts are not specified on the official sign guidance pages linked in Resources; see the municipal code for exact penalties or contact Development Services to confirm.
  • Escalation: Information about first, repeat, or continuing offense ranges is not specified on the cited city pages.
  • Non-monetary sanctions: City remedies can include abatement orders, removal of noncompliant signs, stop-work orders, and prosecution in municipal court where applicable.
  • Enforcer and complaints: Report sign violations to Longmont Development Services or Code Enforcement using the city contact pages in Resources.
  • Appeals: Appeal routes and time limits are governed by the municipal code or administrative appeals rules; specific time limits are not specified on the general sign guidance pages.
If a citation is issued, follow the notice for appeal deadlines closely.

The city publishes a Sign Permit Application or sign-specific application form through Development Services. Fee schedules and submittal methods (online or in-person) are provided on the city permit pages; if a published form or fee is not available, contact Development Services for the current application and fee information.
