Stamped Concrete costs $15.11 to $32.55 per sq ft in Hawaii in 2026. For a 400 sq ft project, that puts the installed total at $6,044 – $13,019, with most projects landing near $9,532. Hawaii is about 16% above the national average.
Why Hawaii prices differ from the national average
Roughly 58% of the installed cost of stamped concrete is labor, and labor is the part of the bill that actually moves between states. Hawaii construction wages average $47.32 per hour against a national figure near $36.97 — a wage index of 1.28×.
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 Hawaii at $15.11 to $32.55 per sq ft, against a national baseline of $13.00 to $28.00.
Two other forces sit on top of that. Metro areas inside Hawaii price above the statewide figure because of wages, permitting, and site access. And the absence of a frost line removes a cost that northern states cannot avoid.
Stamped Concrete cost by project size in Hawaii
These figures apply the Hawaii rate to common project sizes. They cover a standard specification with normal site access.
| Project size | Hawaii cost range | Typical |
|---|---|---|
| 10×10 (100 sq ft) | $1,511 – $3,255 | $2,383 |
| 12×12 (144 sq ft) | $2,176 – $4,687 | $3,431 |
| 12×16 (192 sq ft) | $2,901 – $6,249 | $4,575 |
| 16×20 (320 sq ft) | $4,836 – $10,415 | $7,625 |
| 20×20 (400 sq ft) | $6,044 – $13,019 | $9,532 |
| 24×24 (576 sq ft) | $8,704 – $18,747 | $13,726 |
| 30×40 (1,200 sq ft) | $18,133 – $39,057 | $28,595 |
Where the money actually goes
For a 400 sq ft project in Hawaii at roughly $9,532, a typical bill splits like this:
| Line item | Share | Cost |
|---|---|---|
| Labor | 58% | $5,528 |
| Materials | 32% | $3,002 |
| Site prep & equipment | 6% | $600 |
| Overhead, disposal & finishing | 4% | $400 |
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.
Stamped Concrete cost by city in Hawaii
Statewide averages hide a lot. Honolulu, Hilo, Kahului all price above the Hawaii average, while rural counties run below it:
| Area | Cost per sq ft | A 400 sq ft project | vs state |
|---|---|---|---|
| Honolulu | $16.62 – $35.80 | $10,485 | +10% |
| Hilo | $15.41 – $33.20 | $9,722 | +2% |
| Kahului | $16.02 – $34.50 | $10,104 | +6% |
| Rural Hawaii | $14.05 – $30.27 | $8,864 | −7% |
What is included in a Hawaii 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 $950 in Hawaii), 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 Hawaii
A residential permit for work of this type and value in Hawaii typically runs around $950, 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 Hawaii
Hawaii 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 Hawaii
Materials account for roughly 42% of the installed price, so a 400 sq ft project carries about $4,003 in materials against an installed cost near $9,532. The gap is labor, equipment, and the risk of getting it wrong.
Because Hawaii labor runs at 1.28× the national rate, the DIY saving here is larger than in most states, which makes self-performing more tempting. 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 Hawaii compares with nearby states
Hawaii sits in the West region. Here is how neighbouring states price the same specification:
| State | Cost per sq ft | vs Hawaii |
|---|---|---|
| Idaho | $12.25 – $26.38 | Lower than Hawaii |
| New Mexico | $12.25 – $26.38 | Lower than Hawaii |
| Montana | $12.32 – $26.54 | Lower than Hawaii |
| Wyoming | $12.77 – $27.51 | Lower than Hawaii |
| Utah | $12.85 – $27.68 | Lower than Hawaii |
| Arizona | $12.92 – $27.84 | Lower than Hawaii |

Frequently asked questions
How much does stamped concrete cost in Hawaii?
In 2026, stamped concrete costs $15.11 to $32.55 per sq ft in Hawaii. For a 400 sq ft project, the installed total typically lands between $6,044 and $13,019, with most projects near $9,532.
Is stamped concrete more expensive in Hawaii than the national average?
Hawaii is about 16% above the national average. The driver is a construction wage index of 1.28 times the national figure, applied to the roughly 58% of the project cost that is labor.
Which parts of Hawaii are most expensive?
Honolulu, Hilo, and Kahului 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 Hawaii?
Most municipalities in Hawaii require a permit for work of this type and value. Budget around $950 and confirm with your local building department before work starts, since requirements vary between cities and counties.
How deep is the frost line in Hawaii?
Hawaii is effectively frost-free, so there is no frost-depth footing requirement across most of the state.
When is the cheapest time to book this work in Hawaii?
Hawaii 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 58% of the installed price and materials about 42%. 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 Hawaii 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.
