Sign permits are one of the most misunderstood aspects of commercial signage in Chicago. Many business owners are shocked to discover that most signs require a permit — and that the process involves multiple city departments, detailed drawings, and weeks of review time. This guide explains everything clearly.
Does My Sign Need a Permit in Chicago?
In the City of Chicago, a sign permit is required for virtually all permanent signage, including:
- All illuminated signs (channel letters, lightboxes, LED displays)
- Wall-mounted signs larger than 2 square feet
- Projecting (blade) signs
- Awnings with graphic copy
- Pylon and monument signs
- Window graphics covering more than 50% of window area
Generally exempt from permits: small window lettering (under 50% coverage), temporary signs, interior-only signage, and signs smaller than certain square footage thresholds.
Who Issues Sign Permits in Chicago?
The Chicago Department of Buildings (DOB) issues sign permits for properties within city limits. Illuminated signs also require a separate electrical permit through the same department. Pylon signs may additionally require structural engineering review.
For properties in Chicago's nearly 20 Landmark Districts (including Pilsen, Pullman, and portions of Lincoln Square and Wicker Park), the Commission on Chicago Landmarks must also review and approve sign designs before a permit can be issued.
What Do You Need to Submit?
A typical Chicago sign permit application requires:
- Site plan showing the sign's location on the property
- Sign drawings including dimensions, materials, colors, and illumination details
- Elevation drawings showing the sign in context with the building facade
- Electrical specifications for illuminated signs
- Property owner consent (or lease documentation if tenant)
- Contractor license information for the installing company
How Long Does the Permit Process Take?
| Permit Type | Typical Review Time | Notes |
|---|---|---|
| Standard sign permit (Chicago) | 3–6 weeks | Can expedite for additional fee |
| Electrical permit (Chicago) | 2–4 weeks | Often parallel with sign permit |
| Landmark district review | 4–8 weeks | Requires Commission hearing |
| Suburban municipalities | 1–8 weeks | Varies widely by village |
| Pylon sign (structural review) | 6–12 weeks | Requires engineering documents |
Suburban Sign Permits
Every Chicago suburb has its own zoning ordinance and permitting process. Some key differences to know:
- Schaumburg, Naperville, Oak Brook: Strict sign ordinances with tight limits on size, height, and illumination. Budget 4–8 weeks for permit review.
- Oak Park, Evanston: Historic district and design review requirements add time and complexity.
- Des Plaines, Skokie, Niles: Generally faster permit processes, 1–3 weeks in many cases.
What Happens If You Skip the Permit?
Installing a sign without a permit in Chicago can result in fines starting at $600 per day, a city-issued stop work order, forced removal of the sign at your expense, and difficulty selling your property in the future. It's not worth it.
Who Should Handle Your Sign Permit?
Your sign company should handle permit applications as part of the project scope — not hand you a permit application and tell you to figure it out. Magic Sign Design manages the entire permit process in-house for every project that requires one. We prepare all drawings, submit applications, and follow up with city inspectors on your behalf.
Frequently Asked Questions
Can I install a sign before the permit is approved?
No — you must have an approved permit in hand before installation begins. Installing before permit approval is a violation that can result in fines and forced removal.
How much does a sign permit cost in Chicago?
Chicago sign permit fees are based on the sign's square footage and type. Typical fees range from $200–$600 for a standard wall sign. Electrical permits add another $100–$250. Expedited review adds $250–$500.
What if my landlord won't let me pull permits?
Your landlord cannot legally prevent you from obtaining required permits. In fact, installing an unpermitted sign can create liability for the property owner. If your landlord objects, consult with an attorney.
Do I need a permit for a second location if I already have one for my first?
Yes — permits are issued per sign and per address. You'll need a new permit for each location, even if the sign design is identical.
