Why You Need a Sign Permit
In Detroit, all exterior signage for commercial properties requires a Sign Permit, issued by the Buildings, Safety Engineering, and Environmental Department (BSEED). This is mandated by the Detroit City Code, Chapter 50 (Zoning), which governs sign types, sizes, and locations, and is enforced under the Michigan Building Code (locally administered). The primary legal authority is the Detroit Zoning Ordinance (Article 10: Signs), which outlines specific requirements for illumination, placement, and structural safety to maintain city aesthetics and public safety. You can verify the full text in the city's online code library or on the BSEED website.
Installing a sign without this permit triggers immediate enforcement actions with significant business consequences. Based on analyses of BSEED violation notices, the most common penalties include:
- Daily fines that accrue until compliance is achieved. While specific dollar amounts vary by violation, they are levied per day and can quickly exceed the cost of the permit itself.
- Stop-work orders that halt all exterior construction, potentially delaying your opening or renovation timeline by weeks.
- Denial of your Certificate of Occupancy if the sign is part of a new build or major change of use, preventing you from legally opening for business.
- Required demolition of the non-compliant sign at your expense, resulting in a total loss of that investment.
Legal code: State building code (locally administered), local building ordinances, state accessibility code
Recent update: As of 2026, BSEED has integrated its permit application tracking into a centralized online portal, allowing for digital submission of supporting documents and real-time status checks, though in-person review for complex signs is still often required.
Who Needs a Sign Permit?
| Type | Required | Notes |
|---|---|---|
| Restaurant (Full-Service) | Required | Required because the City of Detroit Sign Ordinance § 62-16-3 requires a permit for any wall, projecting, or freestanding sign attached to or on the premises, and restaurants typically install such signs. |
| Bar / Nightclub | Required | Required because illuminated or specialty lighting signs (e.g., neon) are regulated under § 62-16-5 of the Detroit Sign Ordinance, and nightclubs commonly use these. |
| Food Truck | Not Required | Generally exempt because vehicle-mounted signs or signage on a mobile unit are not subject to the permanent sign permitting process per Detroit Zoning Ordinance definitions of 'sign' and 'vehicle.' |
| Coffee Shop / Café | Required | Required as most coffee shops install wall or window signs, which are regulated under Detroit's general sign permit requirements in § 62-16-3. |

Top 5 Sign Permit Mistakes
1. Miscalculating Sign Face Area
Under- or over-calculating the total sign area causes immediate rejection. The City of Detroit's Zoning Ordinance defines area as the entire face of a sign, including framing and borders, not just the logo. For a 4 ft x 6 ft rectangular sign, the correct area is 24 sq. ft. Listing 20 sq. ft. or 30 sq. ft. will cause a plan review delay, adding 2-3 weeks to your timeline.
2. Using Incomplete or Non-Architectural Site Plans
Submitting a hand-drawn sketch or a plan without a scale, property lines, and building footprint leads to rejection. Detroit's Buildings, Safety Engineering and Environmental Department (BSEED) requires a site plan drawn to scale (e.g., 1/8" = 1') showing the exact proposed sign location, dimensions, and distances to property lines. A missing scale bar is the most common flaw, forcing a full resubmission.
3. Incorrectly Classifying the Sign Type
Selecting 'Wall Sign' for a projecting sign (or vice versa) triggers a non-compliance notice, as each type has different zoning rules for size and placement. A sign mounted perpendicular to the building facade is a 'Projecting Sign.' Calling it a 'Wall Sign' misapplies the code, often resulting in a design that exceeds allowable area, requiring a costly revision or variance.

Complete the Sign Permit Application form
Obtain and fill out the City of Detroit's Sign Permit Application form (BSED Form Z-1), which has approximately 45 fields for details like sign dimensions, location, materials, and lighting. Have your business registration (DBA) and property owner's contact information ready. ApronPrep auto-fills business name, address, and owner details to speed this step up. Common tripping points include omitting the electrical contractor license number if the sign is illuminated or providing incorrect zoning district codes, which you can look up using the city's online zoning map. Most applicants complete this form in 45-60 minutes with proper information gathered.
Gather required documentation including site plans and sign specifications
Compile a detailed site plan showing the property lines, building footprint, and exact sign placement (dimensions from property lines are critical). You must also submit detailed sign construction drawings or catalog cut-sheets, including materials, support structures, and electrical diagrams if illuminated. A notarized letter of permission from the property owner is a mandatory but frequently forgotten document. Incomplete plans, especially those missing elevation views, are a leading cause of delayed submission as the city will not accept the package. This gathering process can take 1-3 business days, depending on your architect or sign vendor's timeline.
Submit application and supporting documents to Buildings, Safety Engineering and Environmental Department
File your complete application packet—including the signed form, site plan, sign drawings, and owner permission letter—with the BSED Plan Review Division. Detroit has moved to a hybrid process: you can submit via their online e-permitting portal for initial screening, but a full physical submission may still be required. Ensure you have both digital (PDF) and physical (paper) copies of all drawings ready. Applications submitted without the correct fee payment method information attached are set aside, adding 2-3 business days of processing delay before review even begins.

See All RequirementsProcessing times for a sign permit vary significantly based on the project's complexity and plan review backlog, as reported on the Detroit Buildings, Safety Engineering, and Environmental Department (BSEED) website. For a standard wall sign with complete structural drawings, plan review can take 2–4 weeks. A complex freestanding sign requiring zoning compliance review, which often needs a separate Building Permit, can take 6 weeks or more.
There is no standard government filing fee for the sign permit application itself, per the BSEED application guide. However, total costs vary based on required professional plan reviews, engineering certifications, and city inspection fees. Contact BSEED directly for the most current fee schedule, as costs are project-specific.
No. Permits issued by Detroit BSEED are non-transferable and specific to the approved address, sign structure, and business, as stated in city ordinances. If you move your restaurant, you must submit a new permit application for the new location, which also requires a valid Business License (Restaurant) for that address.
A sign permit itself does not require periodic renewal; it is a one-time approval for installation. However, the sign structure must remain compliant with the original permit and ongoing city codes. You must obtain a new permit for any modifications, repairs, or changes to the sign's size, lighting, or message.
A city inspector verifies the installed sign matches the approved plans in size, location, materials, and electrical connections. They check structural integrity, footing depth for ground signs, and safe attachment to the building. The inspector will also confirm the sign does not obstruct sight lines or violate zoning setbacks. Not legal advice — confirm specific inspection protocols with Detroit BSEED.
