The short answer: a foundation-perimeter regrade in Knoxville typically costs $500 to $2,000, and a broader regrade, covering a side yard, a back yard, or several low spots, usually runs $1,000 to $4,500. A single settled low spot often lands around $900. Full-lot reshaping with new topsoil and seed can run higher, and steep or heavy-clay lots skew toward the top of every range.
Nobody can give you a tighter number without walking the yard — grading prices on soil volume and access, not square footage alone. Here's how those ranges break down by project, what actually moves them in East Tennessee ground, and how to read a quote so you're comparing the same job twice.
Grading cost by project type
Grading isn't one job — it's several different ones wearing the same name. Typical Knoxville ranges by project:
- Foundation-perimeter regrade — $500–$2,000. Restoring fall against the house, usually where builder backfill has settled into a shallow moat.
- A single low spot in the open yard — often around $900 for a straightforward cut-and-fill; less for a small dip, more if fill has to be imported.
- Full back-yard or side-yard regrade — $1,000–$4,500, driven mostly by how much soil moves and whether we're re-establishing lawn afterward.
- Slope or swale cut — priced closer to a swale project, typically $1,000–$4,000, because the goal is a shaped channel rather than a flattened yard.
- Imported fill, by the load — nationally, moved soil runs $50–$200 per cubic yard; on a Knoxville job that cost folds into whichever range above matches the project's overall size.
- Re-seed vs. sod — seed and straw is included in most of the ranges above; sod is a separate line item most homeowners add on top.
Nationally, cost guides put yard grading at roughly $1–$2 per square foot, with a typical whole-yard project landing $1,022–$3,334. Knoxville jobs sit inside that national band but lean toward its upper half — the reason is two words: clay and slope, covered below.
What moves the price
1. Soil volume. How much dirt actually needs to move, from a few wheelbarrows to a dump truck's worth, is the single biggest lever, and it's also the hardest thing to estimate from photos.
2. Access and haul-off. A gate wide enough for a mini skid-steer keeps a job fast and affordable. Fenced yards, mature trees, or a narrow side yard push work toward hand tools, and hauling excess spoil off-site instead of reusing it on the property adds a real line item.
3. Buried utilities. Before anyone cuts into Knoxville soil, Tennessee law requires an 811 call at least three working days ahead — locators then have 72 hours to mark the lines, and the ticket stays valid 15 calendar days. Irrigation heads and shallow utility laterals have to be found and worked around, and that takes real time on the clock.
4. Hardscape. Patios, retaining walls, and driveways near the work area complicate the cut — the new grade sometimes has to tie into an existing wall or walkway rather than just reshape open dirt.
5. Turf re-establishment. A finished grade is bare dirt until grass grows back. Seed and straw cost little; the labor of feathering the new grade smoothly into the surrounding lawn, so it doesn't look like a scar, is what you're really paying for in this line.
Why Knoxville lots price above the national average
What grading actually fights here is two things: clay that holds whatever shape you cut into it when it's wet, and bedrock sitting close under some lots long before a shovel expects it. Knox County's official soil survey rates many of the county's common building soils, including Fullerton, Dewey, Apison, and Corryton, somewhat limited to very limited for construction, citing shrink-swell clay and slope as the reason. On some of these series, bedrock sits as shallow as 7 to 20 inches down, so a crew that expects to cut smoothly through soil instead hits rock, which changes both the timeline and the price.
Knoxville sits at roughly 886 feet of elevation between the Smokies and the Cumberland Plateau, and almost nothing here is flat for long. The west-side hilltops push past 1,000 feet, and House Mountain, the highest point in Knox County, tops out at 2,064 feet. A hillside lot means more cut-and-fill to get a stable grade, more erosion-control work to hold it, and usually a narrower path for equipment to reach the slope at all.
None of that would matter as much without roughly 50 inches of rain a year finding its way into the ground. Red clay barely absorbs water, so a poorly graded slope doesn't just look wrong — it actively sheds every storm downhill, wearing a channel where nobody planned one. Grading clay right means finishing with a real topsoil cap and protecting the bare slope until grass roots can hold it, which is more labor than grading soil that behaves itself.
Permits, code, and the six-inch rule
The rule contractors work to is simple: the ground should fall about six inches over the first ten feet away from the foundation, the same standard the residential building code calls for and the target every yard grading job here restores.
Permits are a separate question from code, and the two local governments answer it differently. In unincorporated Knox County, a Land Disturbance/Grading Permit is required for any land disturbance over 1 acre, and, even under an acre, if the job involves 5 feet or more of cut and fill or more than 10,000 square feet of new impervious surface. Most residential regrades stay well under those thresholds. Inside Knoxville's city limits, check with the city's stormwater office before you start; their rules are a separate set from the county's.
When grading isn't enough
Grading fixes surface water, the rain that lands on your lot and should be running off instead of pooling. It doesn't fix water that's already in the ground. If your yard is soggy in dry weather, or a crawl space stays damp long after the last rain, that's usually groundwater moving through clay and rock, and the fix is a french drain that intercepts it below the surface, typically $1,500 to $5,000 installed — see our french drain cost guide for the full breakdown. Grading alone won't touch that kind of water.
It also doesn't fix roof water dumped four feet from the house. If a downspout is soaking one corner of the yard every storm, rerouting that downspout runs $300 to $800 and often solves the whole problem — regrading around it first would mean paying to move dirt that a few hundred dollars would have kept dry.
When it isn't grading at all
Occasionally a low spot isn't settled ground — it's a hole that keeps reopening no matter how many times it gets filled, or a sudden round depression with no obvious cause. Knox County sits on karst limestone, and while most yard dips are ordinary settlement, real sinkholes are a mapped, physical fact of this ground, not a sales pitch. If that description matches what you're looking at, our guide to telling settled ground from a sinkhole walks through the difference before anyone touches it with a shovel.
How to compare grading quotes
Two bids for the same regrade can land $600 apart because they're not describing the same job. Ask every contractor the same three questions: how many inches of fall are you creating and how are you measuring it, where does the water go when you're done, and who re-establishes the lawn afterward, seed, straw, and cleanup, or is that on you? A bidder who can't answer the second question specifically hasn't designed a fix; they've priced moving some dirt around.
What we quote
We're a Knoxville drainage contractor that starts with the cheapest fix that actually works. We walk the yard, find where the grade fails, and write a fixed price for the smallest job that solves it, which is the process our yard grading service runs on every estimate. Estimates are free anywhere in Knoxville and the surrounding towns, including Farragut, Powell, Maryville, and Oak Ridge, and the price on the page is the price you pay.
