What counts as a concrete slab here

A concrete slab is flat concrete poured at ground level on a compacted base, usually 4 to 6 inches thick, for a patio, a parking area, a side yard, a shed or a sport court. Pad and slab mean nearly the same thing: pad tends to describe a smaller piece that carries one thing, slab a larger flat area. Foundation slabs under a house or garage are a different, structural job and are not covered here.

Sport court and play slabs

A backyard sport court is one of the larger ground-level slabs, and in Phoenix it is named in the permit exemption. The City's "Work Exempt from Permit" bulletin exempts platforms, sidewalks and driveways up to 30 inches above grade, and its commentary adds that sport courts and similar uncovered uses are included. Lighting, fencing over 3 feet or a structure over the court are separate and can need permits.

What a court slab needs

A flat, even surface over its whole area, so the ball bounces true; reinforcement and well-planned joints so cracks stay tight; and a slope gentle enough to drain without being felt in play. A 20x30 half court lands in the $5,700 to $9,800 range in HomeBlue's Phoenix figures.

Pouring a slab in Phoenix heat

Big slabs show heat problems first, because there is more surface losing water. The hot-weather concrete standard, ACI 305.1, allows concrete up to 95 degrees F at discharge, and the Arizona Rock Products Association calls curing the most critical step. Summer slabs are poured at first light and kept wet or sealed while they cure. More in slab thickness, rebar and curing.

Concrete slabs in Phoenix, AZ: frequently asked questions

How much does a concrete slab cost in Phoenix?

HomeBlue's published 2026 Phoenix figures are $7 to $12 per square foot for a reinforced slab. By size it lists a 10x10 at $1,000 to $1,600, a 20x20 at $3,800 to $6,500, a 20x30 at $5,700 to $9,800 and a 30x30 at $8,600 to $14,700. Removing an old slab adds $1.20 to $1.90 per square foot.

Is a concrete slab the same as a concrete pad?

Mostly, yes. People say pad for smaller pieces of concrete that carry one thing, like an AC unit, a shed or an RV, and slab for larger flat areas like a patio or a parking area. Both are flat concrete poured at ground level on a compacted base.

Do I need a permit for a concrete slab in Phoenix?

Not for a slab at ground level on your own lot. The City of Phoenix exempts platforms, sidewalks and driveways no more than 30 inches above grade that are not over a basement and not part of an accessible route, and its commentary adds sport courts and similar uncovered uses. A slab that will carry a building is different.

How thick should a concrete slab be?

HomeBlue's Phoenix guide puts residential slabs at 4 to 6 inches: patios and walkways at the thinner end, and slabs carrying vehicles, a shed or other heavy loads at the thicker end. RV parking slabs are usually 5 to 6 inches with rebar.

Does this include house or garage foundation slabs?

No. Foundation slabs that carry a house, casita, garage or other enclosed building are structural work with engineered plans, and outside what this site covers. Everything here is ground-level flatwork.
