Concrete Slab costs $5.97 to $11.94 per sq ft in Arizona in 2026. For a 400 sq ft project, that puts the installed total at $2,388 – $4,776, with most projects landing near $3,582. Arizona is essentially in line with the national average.

Why Arizona prices differ from the national average
Roughly 50% of the installed cost of concrete slab is labor, and labor is the part of the bill that actually moves between states. Arizona construction wages average $36.60 per hour against a national figure near $36.97 — a wage index of 0.99×.
Materials behave differently. Ready-mix concrete, rebar, mesh, and forming lumber are priced on national and regional commodity markets, so they barely move from one state to the next. That is why we apply the wage index only to the labor share and hold materials at national prices. Doing that puts Arizona at $5.97 to $11.94 per sq ft, against a national baseline of $6.00 to $12.00.
Two other forces sit on top of that. Metro areas inside Arizona price above the statewide figure because of wages, permitting, and site access. And a moderate frost line adds some excavation depth to footings and posts.
Concrete Slab cost by project size in Arizona
These figures apply the Arizona rate to common project sizes. They cover a standard specification with normal site access.
| Project size | Arizona cost range | Typical |
|---|---|---|
| 10×10 (100 sq ft) | $597 – $1,194 | $896 |
| 12×12 (144 sq ft) | $860 – $1,719 | $1,290 |
| 12×16 (192 sq ft) | $1,146 – $2,292 | $1,719 |
| 16×20 (320 sq ft) | $1,910 – $3,821 | $2,866 |
| 20×20 (400 sq ft) | $2,388 – $4,776 | $3,582 |
| 24×24 (576 sq ft) | $3,439 – $6,877 | $5,158 |
| 30×40 (1,200 sq ft) | $7,164 – $14,328 | $10,746 |
Where the money actually goes
For a 400 sq ft project in Arizona at roughly $3,582, a typical bill splits like this:
| Line item | Share | Cost |
|---|---|---|
| Labor | 50% | $1,791 |
| Materials | 38% | $1,343 |
| Site prep & equipment | 8% | $269 |
| Overhead, disposal & finishing | 5% | $179 |
The labor share is why identical projects diverge so sharply between states. It is also why a bid that comes in far below these numbers usually means a thinner specification or a crew cutting site prep, not a genuine bargain.
Concrete Slab cost by city in Arizona
Statewide averages hide a lot. Phoenix, Tucson, Mesa all price above the Arizona average, while rural counties run below it:
| Area | Cost per sq ft | A 400 sq ft project | vs state |
|---|---|---|---|
| Phoenix | $6.57 – $13.13 | $3,940 | +10% |
| Tucson | $6.09 – $12.18 | $3,654 | +2% |
| Mesa | $6.45 – $12.90 | $3,869 | +8% |
| Rural Arizona | $5.55 – $11.10 | $3,331 | −7% |
What is included in a Arizona quote — and what is not
A complete quote for this work should list dimensions, specification and grade, site preparation, materials, labor, cleanup, and disposal. Those are the items already reflected in the ranges above.
Costs that usually sit outside the headline number: permits (around $450 in Arizona), demolition or removal of existing work, unusual site access, drainage or grading corrections, and any upgrade to the standard specification. When two bids differ by thousands, the gap is nearly always one of these, not the labor rate.

Permits in Arizona
A residential permit for work of this type and value in Arizona typically runs around $450, though the figure varies by municipality and often scales with declared project value. Permit cost is rarely folded into a contractor’s per-sq ft quote, so add it separately when comparing bids. Confirm requirements with your local building department before work begins — unpermitted work can surface later during a sale or insurance claim.
Best time of year to schedule in Arizona
Arizona supports work through most of the year. Demand and pricing peak in late spring and summer, so booking in the shoulder seasons usually gets both better availability and better rates.
DIY versus hiring a contractor in Arizona
Materials account for roughly 50% of the installed price, so a 400 sq ft project carries about $1,791 in materials against an installed cost near $3,582. The gap is labor, equipment, and the risk of getting it wrong.
Because Arizona labor runs at 0.99× the national rate, the DIY saving here is closer to the national norm. Weigh it against tool rental, waste disposal, permit responsibility, and the fact that remedial work almost always costs more than doing it right the first time.
How Arizona compares with nearby states
Arizona sits in the West region. Here is how neighbouring states price the same specification:
| State | Cost per sq ft | vs Arizona |
|---|---|---|
| Idaho | $5.70 – $11.40 | Lower than Arizona |
| New Mexico | $5.70 – $11.40 | Lower than Arizona |
| Montana | $5.73 – $11.46 | Lower than Arizona |
| Wyoming | $5.91 – $11.82 | Lower than Arizona |
| Utah | $5.94 – $11.88 | Lower than Arizona |
| Nevada | $6.15 – $12.30 | Higher than Arizona |

Frequently asked questions
How much does concrete slab cost in Arizona?
In 2026, concrete slab costs $5.97 to $11.94 per sq ft in Arizona. For a 400 sq ft project, the installed total typically lands between $2,388 and $4,776, with most projects near $3,582.
Is concrete slab more expensive in Arizona than the national average?
Arizona is essentially in line with the national average. The driver is a construction wage index of 0.99 times the national figure, applied to the roughly 50% of the project cost that is labor.
Which parts of Arizona are most expensive?
Phoenix, Tucson, and Mesa price above the statewide average because of higher wages, stricter permitting, and tighter site access. Rural counties typically run around 7% below the state figure.
Do I need a permit in Arizona?
Most municipalities in Arizona require a permit for work of this type and value. Budget around $450 and confirm with your local building department before work starts, since requirements vary between cities and counties.
How deep is the frost line in Arizona?
The frost line in Arizona is roughly 12 inches. Footings and posts must extend below that depth to avoid frost heave, which adds excavation and material to the job.
When is the cheapest time to book this work in Arizona?
Arizona supports work through most of the year. Demand and pricing peak in late spring and summer, so booking in the shoulder seasons usually gets both better availability and better rates.
How much of the cost is labor versus materials?
Labor is about 50% of the installed price and materials about 50%. That split is why state wage differences move the total so much, and why material price swings move it less than people expect.
Why do contractor quotes in Arizona vary so much?
Three things move a quote most: metro versus rural location, site access and preparation, and the specification itself. Two bids are only comparable when both list the same dimensions, the same grade of material, and the same scope of prep work.
