Land clearing is the most consequential excavation decision you'll make on a residential property. Get it right, and everything downstream — foundation, drainage, landscape, driveway — benefits from a properly prepared site. Get it wrong, and you pay for the mistake in every subsequent phase of the project.
This guide is the umbrella resource for Oregon property owners planning residential land clearing in 2026. It covers what clearing includes, realistic pricing brackets for different lot sizes and conditions, what permits apply, how the process works, and how to avoid the common mistakes that inflate budgets by 30 to 50 percent.
Oregon's vegetation, soils, and rainfall make land clearing here more complex than in most states. The published national calculators don't account for blackberry, Willamette Valley clay, or wet-season access limits. The pricing in this guide reflects real Oregon conditions. For the deeper cost-driver analysis that applies across every scope below, see our Oregon excavation cost factors breakdown.
Land clearing prices vary with lot size, vegetation density, terrain, access, and haul-off requirements. A lot on flat pasture with a few small trees might clear for a fraction of what the same acreage costs on a forested hillside.
Industry Baseline Range
| Lot Size and Condition | Unit | Industry Baseline |
|---|---|---|
| 0.1 acre, light vegetation | per lot | $800 – $3,500+ |
| 0.25 acre, light vegetation | per lot | $1,500 – $6,000+ |
| 0.25 acre, heavy brush + trees | per lot | $3,500 – $15,000+ |
| 0.5 acre, mixed | per lot | $4,000 – $18,000+ |
| 0.5 acre, heavy wooded | per lot | $8,000 – $30,000+ |
| 1 acre, mixed | per lot | $6,000 – $25,000+ |
| 1 acre, heavy wooded | per lot | $15,000 – $50,000+ |
| Per-acre rate (light, accessible) | per acre | $3,500 – $12,000+ |
| Per-acre rate (heavy or rough) | per acre | $10,000 – $40,000+ |
| Stump removal add-on | per stump | $150 – $900+ |
| Haul-off (per load) | per load | $250 – $750+ |
| Rough grade after clearing | per sq ft | $0.75 – $4.00+ |
| Mobilization | flat | $250 – $800+ |
| Minimum job callout | flat | $500 – $1,500+ |
The industry baseline ranges above represent ideal conditions — easy access, workable soil, shallow depth, minimal haul-off. In practice, actual project costs frequently exceed published averages by 2 to 3 times when complications arise. Oregon's clay soils, rocky terrain, unmarked utilities, permit requirements, and disposal fees can all push costs well above baseline figures. The only reliable way to know your actual cost is through an on-site assessment.
Land clearing exposes whatever is under the vegetation. Common discoveries:
A complete residential clearing scope typically covers these phases:
1. Survey and mark-out Verify property lines, mark trees to save, identify protected species, flag utilities, and walk the scope with the property owner.
2. Utility locate (811 Oregon) Call before dig, always. State law requires at least 2 business days notice.
3. Vegetation clearing Remove brush, blackberry, vines, and small trees. Typically handled with a mini-excavator, skid steer, or brush hog depending on density. See our dedicated brush clearing cost and Himalayan blackberry removal guides for per-acre and per-crown pricing.
4. Tree removal Fell and buck larger trees. Many contractors sub this to a certified arborist for trees over a certain size or near structures. If roots from removed trees have already damaged a driveway or sewer line, that becomes a separate tree root excavation scope.
5. Stump removal Grind or excavate stumps per the homeowner's preference and the downstream use of the site — our stump removal pricing guide breaks down grinding vs. full excavation.
6. Debris pull and sort Pull root mats, concrete, buried debris, and brush into sortable piles for disposal.
7. Haul-off Load and haul to appropriate facilities. Oregon separates woody debris (yard waste) from dirt/concrete (landfill or recycler) from construction waste.
8. Rough grade Smooth the cleared area so water drains and the lot is usable. Not the same as final grade for a building pad.
9. Erosion control Install silt fence, straw wattles, or vegetative cover where required by the permit or by common sense on slopes.
Here's how different lot sizes typically break down on a residential Oregon clearing:
Small city infill lots, back-of-property areas, side-yard expansions. Light brush clears in a half-day; heavy blackberry and a few mature trees can still run 2–3 days. Machine mobilization is the same cost whether you clear 4,000 or 40,000 square feet — which is exactly why sub-acre work deserves its own small lot clearing cost guide.
Typical suburban lot size or a piece of a rural property. Mixed conditions usually take 2–5 days. Expect to haul 3–10 loads of debris.
Common for rural residential and larger suburban parcels. Light conditions clear in 2–4 days. Heavy wooded half-acres can take 1–2 weeks. Expect 5–20 loads of debris.
Rural residential, homestead, and small farm lots. Light clearing runs 4–7 days. Heavy conditions with big timber can take 2–4 weeks. Expect 10–40+ loads of debris and likely multiple machines on-site simultaneously.
Timelines depend heavily on conditions:
| Scope | Typical Timeline |
|---|---|
| 0.1 acre mixed | 1–3 days |
| 0.25 acre mixed | 2–5 days |
| 0.5 acre mixed | 4–10 days |
| 1 acre mixed | 7–20 days |
| Add rough grade | +1–5 days |
| Add permit wait | +1–8 weeks |
The Willamette Valley, Coast Range, and western Cascades share three cost drivers: heavy rainfall, clay soils, and Himalayan blackberry. All three push costs up. Dry-season scheduling, tracked equipment, and root-crown excavation are the typical responses.
East of the Cascades, lava rock, basalt cobble, and juniper are the dominant conditions. Juniper clears differently than fir. Rock changes stump removal from grinding to chipping-out. Rural access roads may require their own improvements before equipment can reach the site.
Jackson and Josephine counties deal with fire-prone conditions plus steep slopes. Defensible space clearing is common and has its own rules. Slope often dictates all-hand work instead of mechanical clearing, and properties that want to keep a usable yard after clearing often need sloped backyard solutions or backyard grading as a follow-on scope.
Coastal Oregon has its own challenges — constant moisture, salt corrosion on equipment, and high winds that complicate tree felling. Coastal rates often run 10–20% above valley rates.
Oregon's land-clearing permit landscape is complicated. Key categories:
Portland, Eugene, Lake Oswego, and many Willamette Valley cities require permits to remove significant trees. "Significant" varies by jurisdiction — often trees above 12, 18, or 24 inches DBH, or native species regardless of size.
DEQ 1200-C is the state erosion control permit for construction disturbing 1+ acre. Local jurisdictions have smaller-scale equivalents for disturbances over 500 sq ft, especially on slopes.
DSL (Department of State Lands) regulates fill and removal in wetlands. Local codes regulate riparian buffers 50–200 feet from streams and wetlands. Clearing in these zones often requires permits or is prohibited.
EFU (Exclusive Farm Use), Forest zones, and resource lands have use restrictions. Residential clearing on rural-zoned land may require conditional use approval.
Sites with archaeological or cultural significance (especially along the Columbia and some coastal areas) may trigger SHPO (State Historic Preservation Office) review.
Permit costs typically run $100–$600+ per permit, and the time to issue can be 2–12 weeks.
The full vetting framework — CCB lookup, certificate-of-insurance discipline, and red-flag questions — is in our guide to hiring a residential excavation contractor.
Hiring before permits: Starting work before permits are issued can trigger stop-work orders, fines, and rework.
Ignoring the haul-off plan: Debris piles become problems if they can't leave the site promptly. Confirm where debris goes before work starts.
Combining clearing and grading in one scope: These are two different phases priced differently. A bundled quote can hide variance.
Not accounting for follow-up: Blackberry and ivy require year-2 and sometimes year-3 follow-up visits.
Clearing more than you need: Every cleared square foot is a cost. Mark the scope tightly.
Clearing in the wet season: Saves nothing in the long run. Dry-season work is cheaper and faster.
Very small scopes (under 0.05 acre, grass and light brush, no trees or invasives) can be DIY with rental equipment. Above that, the math tilts toward hiring out fast.
DIY stops making sense when:
Land clearing is the foundation of every subsequent construction or landscape decision on your property. Doing it right the first time is meaningfully cheaper than redoing it later. An on-site walkthrough is the fastest way to get a real scope and a real number.

How much does land clearing cost per acre in Oregon? Industry sources have historically reported residential land clearing at $3,500 to $25,000+ per acre, with heavy wooded or sloped acreage running $10,000 to $40,000+ per acre. Oregon pricing sits at the higher end due to blackberry, clay soil, wet-season limits, and robust permit requirements. Most small jobs carry a $500 to $1,500+ minimum callout.
How long does residential land clearing take? A quarter-acre of mixed conditions takes 2 to 5 days. A half-acre takes 4 to 10 days. A full acre of mixed conditions runs 7 to 20 days. Rough grade after clearing adds 1 to 5 days. Wet-season work adds 20 to 40 percent to those timelines.
Do I need a permit to clear my land in Oregon? It depends on scope and location. Clearing grass and light brush usually doesn't require a permit. Clearing trees above certain sizes, working near waterways, disturbing significant soil on slopes, or clearing for new construction almost always requires permits. Check with your city or county before starting.
What's included in land clearing? A complete scope typically includes vegetation clearing, tree removal, stump removal, debris pulling, haul-off, and rough grading. Erosion control and final grading are often separate scopes. Confirm what's in and out of the written estimate.
When is the best time to clear land in Oregon? June through September is ideal in most of Oregon. The ground is dry, access is good, and haul-off is straightforward. Dry-season work is faster, cheaper, and produces better results than wet-season work. Plan permit applications 2 to 3 months ahead of your desired start date.
