Asphalt paving cost in Tigard depends on five things: project size, base condition, site access, drainage requirements, and the loading the pavement will see in service. A 2,000-square-foot residential driveway in Bull Mountain prices very differently from a 30,000-square-foot retail lot at Tigard Triangle. This guide breaks down the 2026 industry baseline ranges, the site factors that move Tigard quotes up or down, and how to read a written estimate.
What Drives Tigard Paving Cost in 2026
Five cost drivers explain the bulk of price variance on Washington County jobs:
- Square footage: Larger projects benefit from economies of scale. Mobilization, equipment setup, and crew time are spread across more area. A 20,000-square-foot lot will typically come in well under the per-square-foot rate of a 3,000-square-foot driveway.
- Base condition: Tigard sits on Willamette Valley clay sub-base. Clay holds moisture, expands and contracts seasonally, and drains poorly. Sites with soft or saturated subgrade need over-excavation and rebuild before paving, which adds meaningfully to cost.
- Existing pavement removal: Repaving over an existing lot requires demolition and haul-off, which adds $1 to $3 per square foot depending on thickness and disposal fees.
- Drainage and stormwater: Washington County stormwater rules increasingly drive design on commercial work -- LID requirements, inlet placement, and impervious surface limits all affect both engineering and pour cost.
- Access and grade: Tight residential lots in Bull Mountain or steep approaches in the Hills can require smaller equipment or hand work, which slows production and raises labor cost.
A written quote should break out each of these as a separate line item so you can compare bids meaningfully. Bids that come in as a single lump sum are hard to evaluate against alternative scopes.
Tigard Asphalt Paving Cost: 2026 Baseline
The numbers below are published industry averages for the Portland metro and Washington County region. Your actual quote will reflect site-specific conditions, and a thorough on-site assessment is the only way to get a number that fits your project.
Industry Baseline Range
| Project Type | Cost Per Sq Ft | Typical Total Cost |
|---|---|---|
| Residential driveway (2-car, simple) | $3 to $8 | $2,500 to $8,000+ |
| Long residential driveway (200 ft+) | $3 to $10 | $7,000 to $30,000+ |
| Small retail lot (under 10,000 sqft) | $3 to $7 | $20,000 to $70,000+ |
| Mid-size commercial lot (10,000 to 40,000 sqft) | $3 to $7 | $40,000 to $250,000+ |
| Large commercial or industrial (40,000 sqft+) | $2.50 to $6 | $150,000 to $1,000,000+ |
| Resurface / overlay (existing structure good) | $2 to $5 | varies with sqft |
Current Market Reality
Tigard pricing in 2026 reflects a Portland metro market with strong contractor density, which keeps the per-square-foot rate competitive on larger projects. The catch is at the small-job end: a single small driveway or patch can carry meaningful mobilization cost relative to the scope, because crews and hot-mix delivery have fixed setup costs. Pairing a residential job with neighbor jobs on the same street -- or scheduling alongside a Tigard sealcoating refresh -- meaningfully lowers per-square-foot pricing.

Tigard Triangle and Bull Mountain: Two Different Cost Profiles
Tigard splits into two pricing realities by neighborhood. The Tigard Triangle and commercial spine along Pacific Highway / 99W see denser, larger paving jobs -- retail lots, office complexes, and the kind of acreage that benefits from scale pricing. Per-square-foot rates land on the lower end of the range, often $2.50 to $5 on jobs over 20,000 square feet.
Bull Mountain and the hilly residential pockets to the south are a different story. Lots are smaller, access is often constrained, and grade changes can require additional drainage work. Residential driveway pricing in these areas trends toward the upper end of the range, with $5 to $9 per square foot common for typical two-car installations and $7+ per square foot for premium installations with thicker base, decorative edging, or steep grades that require extra drainage.
The single biggest cost surprise on Bull Mountain driveways is unexpected base rebuild -- many original installations from the 1980s and 1990s have thin or compromised bases that look fine until equipment breaks ground.
What a Tigard Paving Quote Should Include
A well-written quote breaks out at minimum:
- Demolition / removal: Square footage and method (mill vs full removal), plus disposal fees
- Excavation and grading: Depth, volume, and disposal of unsuitable soil
- Aggregate base: Thickness (typically 4 to 8 inches), material spec, compaction method
- Hot-mix asphalt: Thickness (typically 2 to 4 inches), mix spec (PG binder grade), lift count
- Drainage and grading: Specific grading targets, drains, French drains, swales if applicable
- Striping and finish: ADA compliance, line work, wheel stops if commercial
- Permits and inspections: What is included vs reimbursed by owner
- Warranty: 1- to 2-year minimum on workmanship is standard
If a bid is materially cheaper than competitors on the same scope, check whether base thickness, asphalt thickness, or drainage is the variable. A cheaper bid that cuts base or asphalt thickness is not a bargain -- it is a deferred cost that will show up in 8 years instead of 20.
Hidden Cost Factors on Tigard Sites
A few line items that surprise property owners on Tigard paving projects:
- Sub-base unsuitability: Willamette Valley clay sub-base in Bull Mountain, Tigard Triangle, and central Tigard can hide soft pockets, organic content, or compromised compaction from older construction. Over-excavation and unsuitable soil disposal can add 5 to 15 percent to project cost.
- Existing utility conflicts: Older parcels along Pacific Highway and Main Street sometimes have buried storm, sanitary, or fiber lines that conflict with new grading plans.
- Stormwater retrofits: Existing impervious-surface coverage on older commercial parcels often does not match current Washington County requirements. Repaving may trigger LID compliance updates -- swale construction, inlet additions, infiltration trenches.
- Tree-root conflicts: Mature trees in residential Tigard neighborhoods can have surface roots that conflict with grading depth. Tree-protection scope is sometimes a separate line item.
- ODOT review: Work touching Highway 217, Highway 99W, or I-5 frontage requires ODOT review, adding 2 to 4 weeks to permit timeline.
A thorough on-site walkthrough catches most of these before they become change orders.
How to Get an Accurate Tigard Quote
Online cost guides give ranges. To know what your specific project will cost, schedule an on-site walkthrough. We bring a written estimate that breaks out every line item, with thickness and mix spec explicitly listed. The walkthrough takes 30 to 45 minutes for typical residential work, longer for commercial sites with stormwater complexity.
