Do You Need a Permit for a Concrete Slab? A Simple Guide for Homeowners (2025)
Thinking of installing a concrete slab for a patio, driveway, or shed? Here’s one question you need to ask before getting started:
Do I need a permit for a concrete slab?
In many cases, the answer is yes. Getting the right permit helps you stay legal and avoid expensive issues later.
Let’s break it down step by step.
Why Permits for Concrete Slabs Matter
Permits help ensure your concrete slab is safe, durable, and up to code. Local governments use permits to check:
- Drainage and slope
- Structural safety
- Setback and zoning rules
- Skipping this step can lead to fines or having to tear up your work.
When Is a Permit Required?
Every city or county may have its own rules. However, you’ll usually need a permit if:
- The slab supports a structure (like a garage or shed)
- It’s over a certain size (often 400 square feet)
- The slab affects drainage or touches the sidewalk or road
Example: Fayetteville, NC
In Fayetteville, you may need a permit for:
- Concrete patios or driveways over 400 sq ft
- Garage or shed foundations
- Any slab attached to your home
Always call your local permitting office before you start!
How to Get a Concrete Slab Permit
Here’s a simple breakdown of the permit process and what to expect:
- Call or visit your local building department
- Fill out an application online or in person
- Submit drawings or a site plan
- Pay the fee (usually $50–$300)
- Wait for approval (a few days to a week)
- Schedule inspections, if needed
What Happens If You Skip the Permit?
Skipping a permit might feel like no big deal—until it is. You could face:
- City fines or penalties
- Delays when selling your home
