If you own a storefront in the Chicago suburbs, you already know that signage regulations change the moment you cross a municipal line. A blade signage strategy that wins approval in Lake Zurich might stall in Blue Island or trigger a public hearing in Homer Glen. This is not a minor inconvenience; it is the reality of a region where every suburb writes its own rules. Lake Zurich, for example, codifies signs under Title 12, Chapter 1. Blue Island lists a separate Signage Approvals section. Homer Glen ties signage to site plan review under its zoning ordinance. A single "Chicago suburbs" playbook does not exist. This tutorial will walk you through the process of navigating those local codes with confidence. You will learn what blade signage is and how it differs from fascia or monument signs. We will examine why blade signs work harder for storefronts. Then we will address how to verify details in your local code, from permits and zoning review to public hearings and electrical rules. You will also discover design choices that simplify code review and what to bring to your first meeting with a signage studio. By the end, you will have a clear path to a blade sign that passes review.
What Is Blade Signage? A Working Definition for Storefront Owners
Blade signage, sometimes called a projecting or perpendicular sign, extends outward from the building face so it is readable from both directions along the footpath. Verify your municipality's exact definition, since code labels vary. Formats to explore with your fabricator include flat panels, illuminated cabinets, and edge-lit options, among others; construction and illumination are typically regulated separately, so the format you choose will determine which code sections apply. Washougal, WA, for example, lists projecting signs in their own section and addresses illumination separately (Washougal sign index).

Vocabulary creates confusion. Blade, projecting, hanging, and perpendicular sign are often used interchangeably, but a municipal code may define only one and treat the others differently. Never assume a synonym satisfies a permit condition.
These signs suit walkable retail corridors, restaurant and bar frontages, salons, breweries, and any shopfront where pedestrians approach from two directions. A Baguette Neon Sign can mark a bakery, while a Neon Arrow LED Sign aids wayfinding. Explore Our Bestselling Neon Collections for more formats.
Treat blade signage as an addition to fascia signage, not a replacement. Plan both, then confirm how each counts toward the facade's total allowed signage area. Projection limits, minimum clearance above footpaths, and maximum areas are set by each municipality. Verify them in the adopted code text, not a general article.
Blade Sign, Fascia Sign or Monument Sign: Which One Does the Job

Fascia signs face the street, mounted flat against the facade. A blade sign occupies the zone between the fascia and the sidewalk, catching the eye of people already on foot and flagging an entrance a flat panel can miss. Monument signs serve setbacks and parking areas; check the local code for downtown or corridor restrictions before specifying one.
The trade-off is surface area. A blade sign delivers strong pedestrian visibility but offers less messaging room than a fascia sign of similar cost. The practical answer is layering: let the fascia carry the brand name, and give the blade the icon, category or short name that stops sidewalk traffic.
Note that code limits are set per sign type. Adding a blade sign can reduce how much fascia signage remains permitted on the same facade, since allowances are often calculated per lot or per facade.
Why Blade Signs Work Harder Than Most Storefront Signage
As noted above, the two-direction legibility of a projecting sign distinguishes it from a flat fascia panel, it meets the pedestrian already in motion, confirming the correct entrance before hesitation sets in. Blade signage also breaks the visual plane of a repetitive storefront row. In corridors where every facade looks similar, a perpendicular sign creates a distinct silhouette against the building line. That placement sits directly in the pedestrian sightline. Blade signs double as wayfinding in multi-tenant buildings, retail centres and downtown districts where directories are small or poorly placed. As the previous section notes, a compact blade sign can also extend brand presence where fascia area is already constrained. These are design and visibility advantages, not measured performance claims. The next section explains how to verify the rules that govern them.
Sign Codes Change at Every Suburb Line, So Verify Yours
That pedestrian visibility only counts if the sign is permitted. No single Chicago-suburbs rule governs blade signage. Each municipality adopts and amends its own sign regulations, so neighbouring towns can answer the same question differently. Verify the code that applies to your address before ordering fabrication.
Lake Zurich codifies signs under Title 12, Chapter 1 (Sign Regulations), currently through the 2026 S-17 supplement. Blue Island publishes a Signage Approvals section in its permit documentation, with a Commercial Sign Application in the appendix; treat that application as your practical starting document. Homer Glen Ord. No. 26-036, adopted 27 May 2026, amended business licensing, liquor and zoning; Article X, Section 220-1005 is titled Signs, and Section 220-1001 places signage within site plan review, so a blade sign tied to a larger project may be reviewed within it.
Repeatable method: identify the municipality with jurisdiction, pull the current sign code article, and confirm the amendment date or supplement number before relying on any summary.
Blade Sign Details to Verify in Your Local Code
With the adopted text in hand, work through seven variables that decide whether a blade signage concept is buildable. No standard values exist across municipalities, so each answer must come from your own code.
Projection from the building face. How far the sign may extend over the public way or a private walkway. This figure caps both panel size and bracket reach. Projection over public land may also trigger a separate encroachment or licence agreement outside the sign article.
Minimum clearance above the pavement or grade. The vertical gap between the sign's lowest edge and pedestrian head height. It varies by municipality and sometimes by street type, and accessibility rules may add a second limit.
Maximum area and height. Permitted square metres per face, overall dimensions, and any separate cap on how high a projecting sign may be mounted.
Mounting and structural requirements. Approved attachment methods, wall reinforcement, wind load documentation, and whether engineered or stamped drawings must accompany the submittal.
Illumination and electrical rules. Whether illuminated, animated or flashing projecting signs are permitted, which transformer and circuit provisions apply, and whether a separate electrical permit is required.
Counting rules. Whether a double-sided blade counts as one sign or two, and whether it consumes part of the facade's total signage allowance.
Overlay and historic district restrictions. Downtown design overlays, heritage or historic preservation districts, and corridor plans can tighten every limit above.
Record each answer in writing, because these figures set the scope of your submittal.
The Approval Path: Permits, Zoning Review and Public Hearings
Once the code limits are clear, the approval path depends on where the blade signage sits and what it is attached to. Start with jurisdiction and zoning. Confirm the address, the zoning district, and whether an overlay or planned development designation applies; those designations decide who reviews the sign. Blue Island's handbook asks applicants to determine zoning conformance first. Next, assemble documentation before you submit: a site plan or facade elevation, proposed blade sign dimensions, mounting details, and material and lighting specifications. Step three is the sign permit application, filed with the municipality's building or community development department on the form that town publishes. Blue Island lists a Commercial Sign Application in its permit appendix. Review type varies. It may be administrative staff approval, zoning or design review, or a full public hearing. Homer Glen Section 220-1001(B) provides a verified trigger: commercial and industrial developments under 50,000 sq ft (4,645 m²) require a Plan Commission public meeting and Board of Trustees approval, while those over 50,000 sq ft (4,645 m²) are processed as Planned Developments. For illuminated signs, plan for a separate electrical permit and a final inspection sign-off that closes the permit. Sources do not state whether blade signs in Homer Glen or Blue Island are approved by permit alone or require additional review. Confirm that directly with the reviewing department before you order fabrication.
Neon and Illuminated Blade Signs: Electrical Rules to Confirm
Illumination adds a second review layer. A neon or LED blade sign introduces electrical load, transformers and wiring into a structure mounted over a public walkway, moving the project beyond sign permitting into electrical permitting.
Ask your electrician to confirm which edition of the electrical sign standard (often referred to as UL 48 or NEC Article 600) your municipality has adopted, local adoption determines what applies. Confirm with the building department as well.
Ask the building department:
Is a licensed electrician required?
Is a separate electrical permit needed beyond the sign permit?
Where may the transformer or power supply be located?
Ask whether the local code restricts flashing, rotating, or animated illumination, or caps brightness near residential zones, answers vary by municipality. Confirm how the sign is de-energised for service, whether a disconnect is required, and how the mounting allows safe access without scaffolding over the sidewalk.
These rules are unverified per suburb. Read the adopted electrical and sign ordinances and confirm with a licensed electrician. See our Frequently Asked Questions on neon sign specifications, Frequently Asked Questions on custom art signage, and Frequently Asked Questions on decorative neon.
Design Choices That Make Code Review Easier
Even a modestly lit blade sign must satisfy the reviewer before it hangs over a walkway. Six design decisions carry the most weight.
Scale to the pavement, not the facade. Leave generous headroom and keep the projection proportionate to the footpath width; pedestrian safety and clutter are stated purposes of sign regulation in northern Illinois municipalities.
Match the mount to the wall. Masonry anchors, steel standoffs and through-wall reinforcement each demand different documentation; confirm how the assembly handles wind load and show it on the drawing.
Choose materials for freeze-thaw. Ask your fabricator which materials and finishes they recommend for northern Illinois climate conditions.
Design for close viewing. Fewer words, high contrast and a simple icon read better than a crowded panel seen at an angle.
Coordinate with the sign package. Confirm the blade sign does not push the facade past its total permitted signage area or repeat the fascia message.
Keep illumination directional. Modest, shielded lighting reduces glare complaints from residential or mixed-use neighbours, which can complicate renewal or inspection.
What to Bring to Your First Meeting With a Signage Studio
Before design work begins, gather the essentials. Bring the address, zoning district, and any overlay designation; these three facts dictate which code sections and review bodies apply to your blade signage.
Provide current facade photographs, measured elevations in metres, and an inventory of existing signage. This lets the studio calculate how a projecting sign fits within allowed limits.
If you are a tenant, bring your lease or landlord sign criteria. Commercial leases often impose size, mounting, and lighting restrictions on top of the municipal code.
Bring a timeline and budget range. Ask whether engineered drawings, permit submittals, and installation are handled in-house, as these drive cost and schedule.
A Chicago-suburb signage partner can read the adopted code, prepare permit-ready drawings, coordinate the electrical scope, and manage inspection follow-up. For related queries, see our frequently asked questions and frequently asked questions on neon projects.
Finally, request copies of code citations and submittal drawings so you can verify every requirement against your municipality's current ordinance.
Your Next Steps for a Blade Sign That Passes Review
The steps in previous sections, verifying jurisdiction, recording the seven code variables, and confirming review type, converge here into a practical sequence. Commission a signage studio to produce permit-ready drawings before fabrication. Those drawings must show structural attachment, lighting specifications and code citations. Then schedule the electrical permit and inspection alongside installation. This sequencing prevents an illuminated blade sign from sitting dark after it is hung.
