Building Permit vs. Sign Permit: What Every Business Owner Should Know

Not all permits are created equal — learn the difference between building permits and sign permits, when you need each one, and how to avoid costly mistakes.

Why This Mix-Up Costs Businesses Time

When you’re opening a new business or updating your signage, permits are one of the first steps. But here’s the catch: not all permits are the same — and applying for the wrong one can set you back weeks.

In this article, we’ll explain the difference between building permits and sign permits, when you need each one, and how to avoid double fees or delays.

Building Permit Basics

A building permit is typically required for construction work that impacts the structure, safety, or utilities of a property.

Common situations that need a building permit:

• Building a new structure or addition

• Significant renovations or remodels

• Electrical, plumbing, or structural work

• Installing new foundations or footings for large signs

  
  

The building department is focused on life safety and structural compliance. They want to make sure the work is safe, meets building codes, and won’t create hazards for the public.

Sign Permit Basics

A sign permit is specific to your signage — whether it’s a wall sign, monument sign, pylon sign, or directional signage.

Sign permits focus on:

• Size and height compliance

• Location (setbacks, right-of-way clearance)

• Illumination type and brightness

• Number of signs allowed on the property

• Aesthetics and compliance with sign codes

  
  

The planning or zoning department usually reviews sign permits to make sure they match city codes and maintain a consistent look within the area.

When You Need Both

Sometimes a project requires both a building permit and a sign permit. This is common when:

• Installing a new pylon or monument sign with a new foundation

• Doing electrical work that requires inspection

• Adding structural reinforcements to support a large sign

  
  

Failing to get the building permit when it’s required can result in stop-work orders, fines, and delays.

Case Study: Pylon Sign Replacement

Consider this example: A national bank wanted to replace an old pylon sign with a taller one using the same foundation.

• Step 1: We confirmed the foundation’s engineering was still valid (no building permit needed).

• Step 2: We submitted a sign permit with updated height and cabinet design.

• Step 3: The permit was approved, and installation went forward without delays.

• 
  

If we had needed a new foundation, a building permit would have been required in addition to the sign permit.

Key Takeaways

• Building permits focus on safety and structural work.

• Sign permits focus on zoning compliance and aesthetics.

• Sometimes you need both. Always check before you start.

Getting this right the first time saves you from double fees, resubmittals, and frustrating delays.
