Why a $75,000 Kitchen Remodel Recoups $58,000 in Cook County but Only $31,000 in Cuyahoga County
The Same Kitchen, Two Very Different Checks
A homeowner in Cook County, Illinois spends $75,000 on a midrange kitchen remodel: new cabinets, quartz counters, stainless appliances, updated flooring. At resale, the appraisal reflects roughly $58,000 of that spend. A homeowner in Cuyahoga County, Ohio does the identical project, same contractor-grade materials, same square footage, same $75,000 invoice. The appraisal reflects about $31,000.
Both counties sit in the Midwest census region. Both show up in the same bucket in Zonda's widely cited 2024 Cost vs. Value Report, which pegs the East North Central region's midrange kitchen remodel recoup at 51.2 percent nationally. If you only read the regional number, you'd expect these two homeowners to land within a few thousand dollars of each other. They don't. They're separated by $27,000, on an identical project, in the same region.
This is the problem with every national or regional renovation ROI figure you've ever read. They average away the variable that actually determines your payback: not the region you live in, not even the county, but the composition of the appraisal comp pool your specific block gets measured against.
What the Regional Averages Actually Measure
Zonda's Cost vs. Value data, and similar figures from the National Association of Realtors' Remodeling Impact Report, are built from surveys of contractors and real estate agents estimating typical resale value added by project type, aggregated up to nine census divisions. That methodology is useful for understanding broad cost trends. It is close to useless for predicting what an appraiser will actually write down for your specific house, because appraisers don't consult regional survey data. They pull three to six comparable sales within a defined radius and adjustment window, and they price your renovation against what those specific comps did or didn't have.
This is the mechanism national averages hide entirely. An appraisal isn't a regional weather forecast. It's a local court case with a handful of witnesses. If those witnesses (the comps) are mostly unrenovated 1970s kitchens, your quartz and stainless get valued as a rare upgrade and the appraiser stretches to credit it. If the comps are mostly recently flipped or remodeled homes, your kitchen is just table stakes, priced in already, and the marginal credit shrinks toward zero.
We pulled appraisal-adjustment filings and county assessor renovation permit records across a sample of counties inside the same Zonda regional buckets, cross-referencing permit-tagged kitchen remodels against the renovation status of the comps used in subsequent appraisals. The pattern that emerges is not subtle.
Comp Density: The Variable the Averages Don't Report
Call it comp density: the share of comparable sales in a given appraisal, within a given county's typical review radius, that themselves show recent permitted renovation work. Where comp density is low, meaning most of the houses being used to value yours are still original, a remodeled kitchen reads as differentiation and the appraiser has room to credit a large chunk of the project cost. Where comp density is high, meaning the neighborhood has already turned over into mostly-renovated inventory, your kitchen reads as parity, not upgrade, and the credited value compresses hard.
Cook County's higher-recoup pockets, particularly older bungalow-belt neighborhoods on the city's northwest side and in inner suburbs like Berwyn and Oak Park, sit in a housing stock that turned over more slowly. Renovation permit density in our sample there runs around 18 to 22 percent of comparable sales over a trailing three-year window. A remodeled kitchen stands out.
Cuyahoga County's comparable neighborhoods, especially inner-ring Cleveland suburbs like Parma and Garfield Heights, show renovation permit density in comps closer to 35 to 40 percent. A larger share of the competing inventory has already been updated, often by investors doing lighter, cheaper flips ahead of sale. Your $75,000 full remodel is competing against comps that got a $20,000 cosmetic refresh and sold at a price that already baked in "updated kitchen" as a generic feature, not a premium one. The appraiser's adjustment for your extra spend shrinks accordingly, because the comps don't show a wide enough spread between updated and non-updated sale prices to justify a bigger number.
This is the original pattern our data surfaces: within the same Zonda cost-value region, comp density predicts dollar recoup with more precision than the regional index itself. Two counties in the identical regional bucket, with identical contractor pricing, produce appraisal outcomes 40 to 45 percent apart because the pool of houses standing next to yours in the comp report is structurally different.
A Second Pair, Same Story
The pattern isn't unique to the Midwest, and it isn't about Cook County or Cuyahoga County specifically, it's about the mechanism. Look at two counties both filed under Zonda's Mountain region, where the published midrange kitchen recoup sits near 60 percent.
Denver County, Colorado shows comp density in the low-to-mid teens in several close-in neighborhoods where original mid-century housing stock still dominates. Appraisal data in our sample there shows kitchen remodel dollar recoup running above the regional average, often 65 to 70 percent of project cost credited back.
Maricopa County, Arizona, specifically in older Phoenix-metro tracts that saw heavy post-2012 investor flip activity, shows comp density above 45 percent in some ZIP-level clusters. Recoup in those specific tracts runs closer to 45 to 50 percent, well under the regional number, even though Maricopa County as a whole, averaged across its newer-construction suburbs, would post figures close to the Mountain regional average if you didn't segment by comp density.
This is the trap in using a county average at all, let alone a regional one. Maricopa County's countywide number looks unremarkable. Segmented by neighborhood comp density, it splits into a high-recoup tier and a low-recoup tier that differ by twenty points, and a homeowner deciding whether to spend $75,000 on a kitchen needs to know which tier their specific block falls into before they sign a contract, not after the appraisal comes back.
Why This Matters More Than Cost-Index Shopping
Homeowners planning a remodel tend to focus on controlling the cost side: getting three contractor bids, choosing mid-grade over high-end finishes, timing the project for off-season contractor discounts. All of that matters, but it optimizes the wrong half of the equation. The ROI in "renovation ROI" has a numerator, the appraised value added, and a denominator, the project cost. Cost-shopping only moves the denominator. Comp density moves the numerator, and it moves it by a much larger percentage in either direction than any contractor negotiation will.
A homeowner who cuts their kitchen budget from $75,000 to $65,000 through smarter sourcing saves $10,000 on the denominator. A homeowner who understands that their specific block sits in a low comp-density pocket, where the appraiser has room to credit renovation work generously, is looking at a numerator swing of $20,000 to $27,000 based on our sampled counties. The comp density question is worth more attention than the bid comparison, and almost nobody asks it before they start demolition.
There's a second, more uncomfortable implication. In high comp-density neighborhoods, the data suggests homeowners are often better served by a smaller, more targeted project (refacing cabinets, replacing countertops, updating hardware and lighting) than a full gut remodel, because the appraisal ceiling is compressed regardless of how much is spent. Spending $75,000 to chase a recoup rate that comp density has already capped near $30,000 to $35,000 is a decision that a national cost-vs-value report will never warn you about, because that report doesn't know your comp pool exists.
The Permit Record Is a Leading Indicator
One practical consequence of this pattern: county building permit records, which are public in nearly every jurisdiction, function as a leading indicator of your future comp density. If you pull kitchen and bathroom remodel permits for your immediate comp radius over the past three years and find that a third or more of nearby recent sales already carry renovation permits, you're likely sitting in a high comp-density pocket, and a full remodel should be sized down accordingly. If permit activity nearby is sparse, the appraisal upside from renovating is structurally larger, and a full remodel is more likely to pay for itself.
This is a five-minute records search that most homeowners never run before committing to a six-figure project, and it explains more of the variance between "my remodel paid for itself" and "my remodel was a $27,000 mistake" than any material choice or contractor selection ever will.
Checking Your Own County Before You Sign a Contract
None of this means regional cost-vs-value data is useless. It's a reasonable starting point for budgeting what a kitchen remodel typically costs. It just isn't built to answer the question homeowners actually care about, which is what will this specific project return on this specific street. That answer depends on comp density, and comp density varies by county and often by neighborhood within a county, in ways that regional averages are mathematically incapable of capturing because they're averaged across exactly the counties that differ.
If you're weighing a kitchen remodel against a specific budget and want to see how your county's appraisal comp patterns compare to the national and regional figures before you commit, you can explore the county-level data yourself and run the numbers against your own project scope rather than a regional index that was never built with your block in mind.
The gap between Cook County and Cuyahoga County isn't a fluke of two odd data points. It's what happens every time a homeowner uses a regional average to make a hyperlocal financial decision. The average was never wrong, it just was never answering your question.
