How Long Does It Take to Get a Sign Permit?

Quick Answer

A commercial sign permit typically takes 1–6 weeks to obtain. Simple wall signs and window graphics are often approved in 1–2 weeks through over-the-counter or expedited review. Larger signs, freestanding monuments, illuminated signs, or installations in historic districts may require 4–8 weeks due to design review boards and structural engineering requirements.

What Types of Signs Need Permits?

Most municipalities require permits for permanent commercial signage. Here's how sign types affect timelines:

Sign Type	Typical Permit Timeline	Common Requirements
Wall-mounted (flat/channel letters)	1–2 weeks	Site plan, sign dimensions, materials
Window graphics (permanent)	1–2 weeks	Often over-the-counter approval
Monument/freestanding	3–6 weeks	Engineering, foundation plan
Projecting/blade signs	2–4 weeks	Structural attachment details
Electronic/LED message boards	4–8 weeks	Brightness standards, zoning review
Pylon/pole signs	4–8 weeks	Engineering, height restrictions
Awning/canopy signs	2–3 weeks	Structural review, clearance verification

Factors That Affect Your Timeline

Zoning Compliance

Sign codes regulate size, height, placement, illumination, and quantity based on your zoning district. Commercial zones are generally more permissive, while residential-adjacent areas face stricter limits. If your proposed sign doesn't comply with the code, you'll need a variance, which adds 4–12 weeks for a hearing before the zoning board.

Historic District Requirements

Properties in designated historic districts typically require approval from a historic preservation commission or architectural review board. These boards often meet monthly, so missing a meeting deadline can add a full month to your timeline. They review materials, colors, fonts, illumination methods, and mounting techniques.

Structural Engineering

Freestanding signs, large projecting signs, and rooftop installations usually require a structural engineering analysis stamped by a licensed professional engineer. Hiring an engineer and getting stamped drawings takes 1–3 weeks and costs $500–$2,000.

Landlord and HOA Approval

If you lease your space, your landlord likely has sign criteria in your lease. Shopping centers and business parks often have detailed sign programs specifying allowable sizes, materials, and styles. Getting landlord approval can add 1–3 weeks before you even submit your city application.

Step-by-Step Process

1. Check Your Sign Code (Day 1–2)

Review your city's sign ordinance to understand what's allowed for your zoning district. Many cities post these codes online. Pay attention to maximum sign area (often calculated as a percentage of your building facade), height limits, and illumination rules.

2. Design Your Sign and Prepare Drawings (Days 3–10)

Work with your sign company to create scaled drawings showing the sign's dimensions, materials, colors, mounting method, and location on the building or site. Most cities require a site plan, building elevation, and sign detail drawing.

3. Submit Your Application (Day 10–14)

Submit your application with required drawings, a signed landlord authorization, your business license, and the permit fee (typically $50–$500). Many cities accept online submissions. Some offer same-day over-the-counter approvals for simple signs.

4. Plan Review (Weeks 2–4)

The building department reviews your application for code compliance. They check sign area calculations, setbacks, height, illumination standards, and structural adequacy. If corrections are needed, you'll receive a comment letter and must resubmit, which adds 1–2 weeks.

5. Approval and Installation (Weeks 3–6)

Once approved, your permit is valid for a set period (usually 6–12 months). After installation, some cities require a final inspection to verify the sign matches the approved plans and all electrical work is properly connected.

Tips to Speed Up the Process

• Use your sign company's expertise—experienced local sign companies know the code and can design compliant signs from the start.
• Submit complete applications to avoid correction cycles that add 1–2 weeks each.
• Ask about over-the-counter approval for simple wall signs—many cities offer same-day or next-day review for straightforward installations.
• Check for master sign programs if you're in a shopping center—pre-approved sign criteria can simplify the permitting process.
• Apply for electrical permits simultaneously if your sign is illuminated, rather than waiting for the sign permit first.
