Certificate of Appropriateness in Chicago - Steps

Land Use and Zoning Illinois 3 Minutes Read ยท published February 04, 2026 Flag of Illinois

In Chicago, Illinois property owners and contractors must obtain a Certificate of Appropriateness (COA) for work on designated landmarks and within landmark districts to ensure changes meet preservation standards. This guide explains who needs a COA, where to apply, the typical review steps, enforcement risks, and practical action steps so you can prepare applications or appeals efficiently.

Overview

The COA is issued under Chicago landmark controls administered by the Commission on Chicago Landmarks and the Department of Planning and Development. It covers exterior changes, demolitions, and signs on landmark properties. Projects that alter appearance, materials, or structural footprints generally require review before building permits are issued.

Obtain a COA before starting visible exterior work to avoid enforcement actions.

When a COA Is Required

  • Exterior alterations to a designated landmark or property in a landmark district.
  • Demolition or partial demolition affecting a designated resource.
  • New construction or additions visible from public ways on landmark properties.
  • Replacement of significant features, such as windows, cornices, or storefronts.
Not all interior work requires a COA; review the Commission's scope for specifics.

Penalties & Enforcement

Enforcement of landmark controls is handled by city preservation staff and enforcement units within the Department of Planning and Development and by the City Law Department when litigation is necessary. Official pages referenced in Resources list enforcement pathways but do not state fine schedules on those pages.

  • Fines: not specified on the cited pages; see municipal code or enforcement notices for monetary amounts.
  • Escalation: first, repeat, and continuing offences and daily continuing penalties are not specified on the cited pages.
  • Non-monetary sanctions: stop-work orders, restoration orders, permit denial, and court injunctive actions can be applied by the City.
  • Enforcer and complaints: Department of Planning and Development staff and the Commission on Chicago Landmarks enforce COA requirements; complaints may be filed through official contacts in Resources.
  • Appeals and review: appeal routes are available to the Commission or through administrative review; specific time limits for appeals are not specified on the cited pages.
  • Defences and discretion: emergency repairs, previously approved permits, and variances/alternatives may be available; consult staff for whether a reasonable-excuse defense applies.
If enforcement action is threatened, contact preservation staff immediately to learn appeal deadlines.

Applications & Forms

The city publishes COA application forms and guidance through its historic preservation pages; the exact form name/number, fee, and submission instructions are available on official resource pages listed below. If no fee or form number is shown on a resource page, that information is not specified on the cited page.

  • COA application: see the official landmark preservation application and submittal checklist for required drawings and photos.
  • Fees: not specified on the cited pages; check the official application or permit fee schedule.
  • Submission: typically submitted to the Department of Planning and Development or through the city permit portal per instructions on the COA page.

How-To

  1. Confirm landmark designation status for the property with the city before planning work.
  2. Prepare drawings, photos, and materials specifications that show proposed changes and justify preservation choices.
  3. Complete the COA application and attach required documentation; follow submission instructions on the official COA page.
  4. Submit the application and pay any required fee; track the case and respond to staff requests for more information.
  5. Attend any public hearing or staff review; implement conditions of approval or, if denied, prepare an administrative appeal.
Early coordination with preservation staff reduces delays and unexpected requirements.

FAQ

Do I need a COA for paint or routine maintenance?
Minor maintenance that does not change materials or appearance may not need a COA, but confirm with preservation staff before beginning work.
How long does COA review take?
Review times vary by project complexity; the official review schedule is published on the COA guidance page or is provided by staff upon application.
Can I start work while a COA is pending?
Starting work before a COA is issued risks enforcement action; do not begin visible exterior work until approval or temporary measures are confirmed with staff.

Key Takeaways

  • Obtain a COA before exterior work on designated properties to avoid enforcement.
  • Prepare complete drawings and documentation to speed staff review.
