Typical Installed Range
A standard 400-square-foot pad typically costs $2,400 to $4,200 installed in Peoria, or about $6 to $10.50 per square foot.
Asphalt Cost Guide
How much does it cost to install a 20x20 asphalt driveway?
A 20x20 asphalt driveway covers 400 square feet, and Peoria Asphalt typically estimates $2,400 to $4,200 installed in the Peoria area. Base condition, asphalt thickness, and removal of an old surface determine where a project falls within that range.
Quick Summary
- Expect about $2,400 to $4,200 installed, or roughly $6 to $10.50 per square foot, for a 20x20 driveway in Peoria.
- A stable existing base can keep the quote near $2,400 to $3,400; full removal and subgrade rebuilding can raise it to $3,800 to $4,200.
- Two inches of asphalt is the minimum for passenger vehicles, while 3 inches is standard for Peoria's clay-heavy subgrade and summer heat.
- Sealcoating every 2-3 years costs about $150 to $400 for this size and helps a properly installed driveway reach a 15-20 year lifespan.
20x20 Driveway Cost Highlights
Base and Thickness Factors
Stable subgrade costs less than full removal and rebuilding. A standard 2-3 inch hot mix asphalt section also changes material and preparation needs.
Sealcoating and Maintenance
Plan to sealcoat every 2-3 years. On a 20x20 pad, budget about $150 to $400 per application to slow UV oxidation and support a 15-20 year service life.

Stable Base Versus Full Subgrade Rebuild
A side-by-side comparison of paving over a stable compacted base and excavating a failed base. This difference can move a 20x20 quote from $2,400-$3,400 to $3,800-$4,200.

20x20 Cost Snapshot
Stable Existing Base
$2,400-$3,400 for a straightforward 400-square-foot driveway when the existing base is stable.
Removal and Rebuild
$3,800-$4,200 when the old surface must be removed and the subgrade rebuilt.
Site Preparation Share
Grading and compaction typically account for 20-30% of total cost when a driveway needs subgrade rebuilding.
Routine Maintenance Budget
Budget $150-$400 for sealcoating every 2-3 years, then address small cracks or potholes before damage reaches the base.
Driveway Size Cost Table
| Driveway Size | Area | Estimated Installed Cost |
|---|---|---|
| 15x20 | 300 sq ft | $1,800-$3,150 |
| 20x20 | 400 sq ft | $2,400-$4,200 |
| 20x40 | 800 sq ft | $4,800-$8,400 |
| 25x25 | 625 sq ft | $3,750-$6,562 |
| 1,000 sq ft | 1,000 sq ft | $6,000-$10,500 |
| 1,500 sq ft | 1,500 sq ft | $9,000-$15,750 |
| 2,000 sq ft | 2,000 sq ft | $12,000-$21,000 |
What the 20x20 Range Means
The Peoria-area estimate of $2,400 to $4,200 sits within a broader national range of $1,800 to $4,800 for the same footprint. Locally, that is about $54 to $95 per square yard for grading, compaction, a binder course, and a wearing course of hot mix asphalt. Larger residential projects with extended aprons, curb work, or drainage commonly reach $7,000 to $14,000. Converting dirt or gravel to asphalt may add $5,000 to $20,000 in assessed value depending on the market, a consideration in a city that grew from 154,065 residents in 2010 to 190,985.
Factors That Change Your Total
Base stability, old-surface removal, driveway access, and final thickness are the main price variables. A 2-inch layer is the minimum for passenger vehicles, while 3 inches is standard for Peoria's clay-heavy subgrade and summer heat; caliche deposits common throughout Maricopa County may require extra compaction passes. Monsoon season typically runs from July through September, so slope and drainage must move water off the pad. A driveway tying into the public right-of-way or adding a curb cut may require a permit from the City of Peoria Development Services Department, and an HOA may require approval of driveway color and edging.
Common Cost Questions
Is asphalt cheaper than concrete? Up front, generally yes: the broader asphalt comparison is $3 to $4 per square foot for material and labor, while pavers often run $10 to $20+ installed and gravel is often about half the cost of asphalt but may need annual regrading. Chip seal and tar-and-chip fall between gravel and asphalt in cost and durability. When can the surface be used? Asphalt can usually be walked on within a day or two, versus a week-long concrete cure. Can an existing driveway be resurfaced? If the base is solid, an overlay is roughly 40-60% of full replacement; early crack repair costs about $1 to $3 per linear foot, and small pothole repairs typically cost $75 to $300. Do credentials matter? A contractor performing this work should carry a current Arizona Registrar of Contractors C-12 Asphalt Paving classification.
