Concrete Slab Cost
A basic residential concrete slab in Southern California commonly costs about $10-$22 per square foot installed, with roughly $14 per square foot typical for a straightforward reinforced slab. Excavation, base preparation, reinforcement, slab thickness, pump access, finish, and small-project mobilization drive the final price.

What moves the price
- Thickness and reinforcement — Increasing thickness, concrete strength, rebar size, or reinforcement density raises material and labor costs.
- Subgrade and base preparation — Excavation, export, compaction, aggregate base, and correction of weak or expansive soil can materially increase the installed price.
- Access and placement — Limited truck access can require a concrete pump, buggy transport, additional labor, or smaller pours.
- Finish and layout — A simple broom finish and rectangular form are less costly than hard-trowel finishes, integral color, curves, steps, or numerous joints.
- Project size — Small slabs carry disproportionately high mobilization, forming, short-load, and pump costs per square foot.
