Most homeowners call us thinking a driveway or patio doesn’t need a permit. In Oklahoma City, it almost always does. A concrete permit in Oklahoma City is the standard building permit, and the fee starts at $75[1]. You can apply any hour of the day at access.okc.gov. A plan review for a home job takes 5 to 10 business days.
When do you need a concrete permit in Oklahoma City?
Oklahoma City requires a building permit to build, change, repair, or add on to any structure. That wording covers most concrete work.
Driveways. Every driveway needs a building permit. If it meets a public street, you also need a right-of-way permit from OKC Public Works for the curb cut or approach, which is the part that ties into the street. So a typical new driveway takes two permits.
Patios and walkways. Home flatwork generally needs a permit. Edmond, Norman, and some smaller towns in the metro publish a size limit that lets small pads skip the permit. Oklahoma City doesn’t. If your job is close to the line, call the Development Center at (405) 297-2525 first.
Garage slabs and indoor slabs. Yes, you need a permit for a concrete slab here. Any slab that’s part of a building falls under the building code.
Repairs and resurfacing. Small surface repairs may not need one. Anything structural, or anything that covers a lot of ground, should be cleared with the Development Center before work starts.
Commercial concrete. Every commercial job needs permits, with no exceptions.
Still unsure about your job? Call the Development Center before you start. Staff there answer these questions every day, and a five-minute call gets you a straight answer for your address.

How do you apply for a concrete permit in Oklahoma City?
The process runs through OKC Development Services at 420 W. Main St., 1st Floor, Oklahoma City, OK 73102. The phone number is (405) 297-2525.
- Find out which permits apply. Your job may need a building permit, a right-of-way permit, or both.
- Pull your papers together. You’ll need a site plan that shows where the work goes, its size, and how far it sits from your property lines. Bigger jobs may need drawings that show the steel.
- Apply. Use the Accela Citizen Access portal at access.okc.gov, or apply in person at the Development Center.
- Wait for the review. Simple jobs sometimes get approved at the counter the same day. Home jobs that need a plan review take 5 to 10 business days, and commercial jobs usually take 1 to 3 weeks.
- Get the permit. Once it’s approved and the fees are paid, the city issues it. Post it at the job site.
- Book your inspections. Use the online portal, or call the inspection line at (405) 316-5656.
What does a concrete permit cost in Oklahoma City?
OKC sets concrete permit fees by the type and size of the job.
| Project Type | Fee |
|---|---|
| Minimum permit fee | $75[1] |
| New construction | $0.16[2] per sq ft |
| Alterations and repairs | $6[3] per thousand dollars of project value, plus the minimum fee |
| Plan review (when required) | half the permit fee, capped at $2,750[4] |
| Failed inspection (reinspection) | $50[5] |
| After-hours inspection | $140[6] |
For a typical home driveway, the permit usually runs $75 to $150[7], depending on its size. Commercial jobs cost more, because the plan review fee climbs fast on a big job.
These are the city’s fees, not your contractor’s. A contractor who handles permits will pull yours in their own name and keep track of the inspection dates.
What do inspectors check before the pour?
The pre-pour inspection comes after the forms and steel are set, but before any concrete goes in. For flatwork, it’s the inspection that matters most.
Inspectors look at:
- The steel: its size, spacing, and placement, and how far each piece overlaps the next
- The forms: their size, their level, and the slope that carries water away
- Pipes or sleeves in the slab: if any utilities run through it
- The base under the slab: OKC sits on clay that moves as it gets wet and dries out, so the packed base under your flatwork is what keeps it from cracking and settling within a few years
Driveway approach work at the curb gets its own inspection from OKC Public Works, once before the approach is poured and once after. A building department inspection does not cover the right-of-way part. Book both.
What are the concrete requirements in OKC code?
Oklahoma City follows the 2018 International Residential Code (IRC) with 2022 changes, plus the 2018 International Building Code (IBC). These are the numbers that matter for concrete work.
Slab thickness:
- Floors on the ground: 3.5 inches at least, per the IRC
- Home driveways: 4 inches is the trade standard, but Public Works wants 6 inches for driveway approaches at the curb
- Thicker is better in OKC, because the clay moves
Strength (PSI, or pounds per square inch):
- Indoor concrete that holds up no structure: 2,500 PSI at least
- Outdoor concrete out in the weather: 3,000 PSI at least
- OKC gets a moderate amount of freezing and thawing, and it’s enough to matter, so a 4,000 PSI mix for driveways and outdoor slabs is common
Frost depth: 18 to 20 inches below the ground. Footings have to reach that deep. It doesn’t apply to flatwork itself, but it does apply to any footing or wall tied to the slab.
Vapor retarder: 6-mil plastic sheeting (polyethylene) is required under indoor slabs on the ground. Driveways, outdoor walks, and patios don’t need it.
Our clay deserves its own warning. Clay shrinks when it dries and swells when it gets wet, and OKC sits on some of the most active soil in the state. The Grainola-Lucien and Zaneis soil types cover much of the metro. The USDA rates their shrink and swell as “severe” for a slab on the ground unless the base is built for it. Skip that base work, and flatwork will crack and shift no matter how good the concrete is. No mix can make up for moving ground.
Our slab prep before the inspector comes
Most permit guides end at the inspection checklist. What keeps an OKC slab flat through years of wet and dry happens before the inspector ever shows up. We work in this order:
- Dig and test the ground. We dig 4 to 6 inches below grade. Then we roll a loaded skid steer over the bare clay (proof-rolling) to find soft spots before any rock goes down. Those soft spots can’t be seen from the top, and they’re the main reason home slabs in OKC settle and crack.
- Build the base. We lay crushed limestone in two layers and pack each one, checking how tight it is before the next layer goes on.
- Set the steel. The steel sits on small stands (chairs) with 2 inches of concrete below it. Steel lying on the dirt does nothing.
- Call for the inspection. Only then do we book the pre-pour inspection.
That order adds half a day to the schedule. It’s what gives our OKC slabs their best shot at holding up through the clay’s swings year after year.
We’ve watched slabs crack in under two years when a contractor poured right on the clay. Then the homeowner spent twice the first budget to tear it out, regrade, and pour again. The code is the least you can get away with, and OKC clay asks for more.
Working with a contractor on permits
If you’re hiring someone for your Oklahoma City driveway, garage slab, or other flatwork, bring up permits in the first conversation. A contractor who waves off permits may cut other corners too.
The right contractor will:
- Tell you which permits your job needs
- Pull them before any work begins
- Book the pre-pour inspection and pass it
- Keep you posted if anything comes up while the city reviews your plans
Bel Covo works across the Oklahoma City metro area, and permits are part of our job. For scale, a 600 square foot driveway in the metro runs $4,350 to $10,300 before the drive cost, which covers our trip to your site.
For questions about your exact address, the Development Center at (405) 297-2525 has the final word, and city staff can tell you what applies. A permit costs less than a stop-work order. It costs a lot less than tearing out a slab.
