Concrete Slab Cost in Florida
Quick answer: a 4-inch concrete slab in Florida costs about $6.00 – $12.00 per sq ft installed, 12% below the U.S. average. A 12 × 12 ft patio runs about $1,040 – $1,820, a 24 × 24 ft garage floor $3,830 – $6,890 and a 20 × 40 ft driveway $5,240 – $9,470.
Florida's concrete prices sit below the national average in our model, with the Miami metro a little higher than the rest of the state. There is no frost line to dig below, but Florida has its own items: termite treatment under slabs that will be inside a building, a high water table near the coasts, and afternoon storms that can ruin a fresh finish.

4-inch slabs unless shown. Installed: forms, broom finish and labor, up to vapor barrier, #4 rebar and contractor overhead and profit. DIY: concrete (ready-mix or 80-lb bags, whichever is cheaper) and forms, up to vapor barrier and rebar. Excavation, gravel base and permits are extra.
Metro Areas
Prices in the biggest metro areas differ from the state as a whole, mainly because of labor costs.
| Area | Factor | Slab per sq ft | 12 × 12 patio | 24 × 24 garage | 20 × 40 driveway |
|---|---|---|---|---|---|
| Florida (statewide) | 0.88 | $6.00 – $12.00 | $1,040 – $1,820 | $3,830 – $6,890 | $5,240 – $9,470 |
| Miami metro, FL | 0.92 | $6.50 – $12.00 | $1,070 – $1,870 | $3,970 – $7,100 | $5,430 – $9,770 |
Building a Slab in Florida
| Weathering (IRC) | Negligible statewide. |
|---|---|
| Concrete strength | 3,000 PSI is standard for patios, driveways and pool decks (2,500 PSI is the code minimum). 3,000 PSI ready-mix runs about $119 – $141 per yd³ here. |
| Frost depth | No frost depth to speak of. Footings still go at least 12 in below undisturbed ground under the building code. |
| Soil | Mostly sand, which drains and compacts well, but with a high water table near the coasts, pockets of organic muck, and sinkhole-prone limestone in parts of central Florida. |
| Pouring season | Year-round. From June to September, pour in the morning so finishing is done before the afternoon thunderstorms, and keep plastic on hand to cover the slab. |
- A slab under a house, attached garage or enclosed room needs termite protection before the pour under the Florida Building Code, usually a soil treatment. Ask whether the bid includes it.
- Carport, shed and screen-room kits are anchored to the slab for wind. Check the product approval for the slab thickness and edge distance its anchors need before you pour.
- Pool decks are usually 4 in thick with fiber or mesh; textured cool-deck or paver finishes cost extra.
Frost depths and permit rules are set by your city or county; check with the local building department before you dig. A permit for a small residential slab or driveway typically costs about $50 – $350.

Picking a location sets the ready-mix, excavation and labor rates below to that area's typical level. You can still type your own local prices afterwards. Slab prices by state.
Closer spacing uses more steel and raises the rebar cost.
Not charged when bagged concrete is selected.
A scaled plan of your slab: rebar grid at the spacing you chose, support chairs about every 3 to 4 ft, and the recommended control-joint saw cuts (2.5 times the thickness in inches, in feet, capped at 15 ft). It redraws as you change the inputs.
| Scope Item / Material Description | Amount |
|---|
Enter the total your contractor quoted. We compare it with a benchmark for the same slab and scope you set in the calculator: materials at your entered prices plus labor at the regional standard rate, before any overhead or profit. Make sure the calculator scope (base, rebar, finish, pump, demolition) matches what the bid includes.
Optional: enter the bid's line items to see where the markup sits
Enter the forecast for pour day. The check follows ACI 306R (cold weather) and ACI 305R (hot weather) and estimates the surface evaporation rate that drives plastic shrinkage cracking.
How These Prices Are Worked Out
These are modelled prices, not quotes collected from Florida contractors. Each project is priced with the same line items as the slab cost calculator at national unit prices, then Florida's location factor of 0.88 is applied to ready-mix concrete and labor, as the calculator does when you pick Florida. Bagged concrete, forms, rebar and the delivery fee stay at national prices. The factors are approximate, set by our editors to reflect typical construction cost differences between states; the full method is in the 2026 concrete price report.

Florida Concrete Questions
About $6.00 to $12.00 per sq ft installed for a 4-inch slab with forms, a broom finish and labor, 12% below the national average. A 12 x 12 ft patio runs about $1,040 to $1,820 and a 24 x 24 ft garage floor (5 in) about $3,830 to $6,890. Excavation, gravel and permits are extra.
A 20 x 40 ft driveway, 5 inches thick with rebar and a broom finish, costs about $5,240 to $9,470 installed in Florida ($6.50 to $12.00 per sq ft). Removing an old driveway and the street apron are extra.
About $119 to $141 per cubic yard for 3,000 PSI ready-mix before delivery fees, and about $126 to $158 for 4,000 PSI. Small loads add a short-load fee of $80 to $200 or more.
In the Miami area our model puts 3,000 PSI ready-mix at about $124 to $147 per cubic yard before delivery, and a 4-inch slab at about $6.50 to $12.00 per sq ft installed, 8% below the U.S. average. A 12 x 12 ft patio runs about $1,070 to $1,870 and a 20 x 40 ft driveway about $5,430 to $9,770.
For a slab under a building (a house, an attached garage or an enclosed addition), yes: the Florida Building Code requires termite protection, usually a soil treatment applied just before the pour. A detached patio, driveway or pool deck does not need it.
