Audit support includedFlat price for every study3 to 5 business days Renovating a rental property does not automatically hand you bonus depreciation on the entire project. Only the portion of the renovation identified as 5-year, 7-year, or 15-year property in a cost segregation study qualifies for bonus depreciation, and that share typically runs 20% to 45% of the renovation invoice depending on the scope of work. Assets placed in service after January 19, 2025 qualify for 100% bonus depreciation under the One Big Beautiful Bill Act (OBBBA), while the building shell itself stays on a 27.5-year schedule with zero bonus eligibility. The part most owners miss: whether a line item counts as a repair or a capital improvement changes how (and when) it gets deducted, and getting that call wrong is a recurring theme in the IRS Cost Segregation Audit Technique Guide.
- Renovation assets placed in service after January 19, 2025 get 100% bonus depreciation under OBBBA in 2026.
- A cost segregation study on a renovated rental typically reclassifies 20-45% of the project cost into 5, 7, or 15-year property.
- The building shell keeps its 27.5-year schedule no matter how much you spend on the renovation.

Why this matters
A renovation is one of the best moments to run or update a cost segregation study, because the invoices already break out labor and materials by component. Owners who skip this step depreciate the whole renovation over 27.5 years for a long-term rental, or the applicable straight-line schedule for a short-term rental, and leave the shorter-life assets sitting inside that slow schedule for no reason.
For W-2 earners using the short-term rental loophole, the renovation year is often the highest-leverage year to accelerate depreciation, because the reclassified assets can offset active income the same year they're placed in service. Distinguishing a repair from a capital improvement at the invoice level is the first step, and it happens before any cost segregation math starts.
Bonus Depreciation After Renovating a Rental Property
When a renovation touches a residential rental, each component gets sorted into one of three buckets: land improvements (15-year), personal property (5-year or 7-year), or building structure (27.5-year). Only the first two buckets carry bonus depreciation eligibility in 2026. A cost segregation study for a renovated or remodeled property walks through the renovation invoice line by line to make that sort.
| Renovation Component | Typical Asset Class | Recovery Period | Bonus Eligible in 2026? |
|---|---|---|---|
| Kitchen cabinets, countertops, fixtures | Personal property | 5-year | Yes, if function and documentation support it |
| Removable flooring | Personal property | 5-year | Yes, if not integral to the structure |
| New roof | Structural component | 27.5-year | No |
| Deck, patio, walkway | Land improvement | 15-year | Yes |
| HVAC system | Building system | 27.5-year or shorter, depending on function | Conditional |
Classification, recovery period, and bonus eligibility depend on the asset's function, the documentation behind it, the placed-in-service date, and the taxpayer's own facts. No renovation line item is automatically assigned a recovery period without that review.
Renovations Placed in Service After January 19, 2025: 100% Bonus Depreciation
Renovation assets placed in service after January 19, 2025 qualify for 100% bonus depreciation under OBBBA, meaning the entire reclassified cost of an eligible 5, 7, or 15-year asset can be deducted in the year it's placed in service, not just a portion of it. This restores the full first-year write-off that had been phasing down before OBBBA passed. A $40,000 renovation with 30% reclassified into shorter-life property puts roughly $12,000 into the 100% bonus category for that tax year in 2026.
Renovations Placed in Service in 2024: 60% Bonus Depreciation (2024 Rate)
Renovation assets placed in service in 2024 are stuck at the 2024 bonus rate of 60%, since OBBBA's 100% rate applies prospectively rather than retroactively to earlier placed-in-service dates. That means the same $12,000 in reclassified assets only gets a $7,200 first-year deduction at 60%, with the rest recovered on the normal depreciation schedule for that asset class. Owners who renovated in late 2024 should confirm the exact placed-in-service date with their CPA before assuming the 100% rate applies.
Why the Reclassified Percentage on a Renovation Varies
The share of a renovation that qualifies for bonus depreciation swings widely from project to project. Six factors drive most of that variation:
- Scope of the renovation. A cosmetic refresh (paint, fixtures, appliances) reclassifies a higher share than a structural renovation (framing, roof, foundation work).
- Property type. Short-term rentals furnished for guest use tend to carry more personal property (furniture, electronics, outdoor amenities) than a bare long-term rental.
- Documentation quality. Itemized contractor invoices separate materials and labor by component, which supports a stronger reclassification than a single lump-sum invoice.
- Repair vs. capital improvement treatment. A repair that restores an asset to its prior condition is expensed differently than a capital improvement that adds value or extends useful life.
- Timing of the placed-in-service date. The date drives whether the renovation falls under the 100% OBBBA rate or an earlier phase-down rate.
- Whether a prior study already exists on the property. A renovation on a property with an existing cost segregation study usually needs a supplemental study rather than a full restart, which changes how components get tracked.
A new roof after a cost segregation study is a common example of an asset that stays on the 27.5-year schedule even after a full renovation, since it's a structural component rather than personal property or a land improvement.
“The renovation invoice tells you what you spent, not what recovery period each dollar belongs to.”
Do you need a new cost segregation study after renovating a rental property?
You typically need a supplemental cost segregation study, not a full restart, when a renovation adds new assets to a property that already has a study on file. The supplemental study only analyzes the new construction or renovation costs, which keeps the engagement scoped to the added components rather than re-analyzing the original building.
Can you claim bonus depreciation on a renovation without a cost segregation study?
You can claim bonus depreciation without a formal study, but only on assets you can independently document as 5, 7, or 15-year property, which is a narrower and riskier path than an engineering-based analysis. Most owners without a study end up depreciating the entire renovation over 27.5 years by default, missing the shorter-life assets entirely.
Is a kitchen remodel a repair or a capital improvement for tax purposes?
A kitchen remodel is generally treated as a capital improvement when it upgrades or replaces cabinets, countertops, and fixtures beyond restoring them to original condition, which changes how and when the cost is deducted. A repair that simply fixes what's broken (patching a cabinet, replacing a single fixture) is usually expensed in the year paid rather than depreciated, so the distinction matters before any cost segregation analysis begins.
Running a residential cost segregation study on a renovated property is where the reclassification actually gets identified and documented for your CPA. Virtual Cost Segregation's flat-fee reports are built for this exact scenario: a renovation, refresh, or remodel on an existing residential rental or short-term rental, with support in case the return gets audited.

FAQ
What is the bonus depreciation rate for a rental property renovation in 2026?
Renovation work begun after January 19, 2025 qualifies for 100% bonus depreciation under OBBBA. Renovations begun earlier follow the old phase-down rate for the year placed in service, such as 60% for 2024.
How much of a renovation typically qualifies for bonus depreciation?
20% to 45% of a renovation cost typically gets reclassified into 5, 7, or 15-year property eligible for bonus depreciation. The exact share depends on the scope of work, documentation, and whether the property is a short-term or long-term rental.
Does a new roof qualify for bonus depreciation after a renovation?
A new roof is generally a structural component depreciated over 27.5 years, not bonus-eligible, because it's part of the building shell rather than personal property or a land improvement. This holds true even when the roof is installed as part of a larger renovation.
Can you take bonus depreciation on renovations to a property you've owned for years?
Yes, a supplemental cost segregation study can analyze renovation costs on a property you've owned for years without restarting the original study. Only the new renovation costs get reviewed and reclassified.
Is furniture bought during a rental renovation eligible for bonus depreciation?
Furniture is typically classified as 5-year personal property and qualifies for 100% bonus depreciation when acquired and placed in service after January 19, 2025. Documentation showing the purchase date and use in the rental supports that classification.
Do repairs made during a renovation get depreciated at all?
Repairs that restore an asset to its original condition are usually expensed in the year paid rather than depreciated, separate from capital improvements. Sorting repairs from capital improvements before filing avoids misclassification on the return.
How long does a cost segregation study take after a renovation?
A residential cost segregation study, including one scoped to renovation costs, typically completes in 3 to 5 business days once the required documents are submitted. No site visit is required for most residential rental and short-term rental engagements.
One last thing
When a renovation replaces an asset that still had basis left, like an old roof or old flooring, a partial asset disposition can let you write off the remaining undepreciated basis of the thing you tore out in the same tax year, on top of the bonus depreciation on the new asset. Most owners only think about the new renovation cost and never claim the disposition on what got removed, which leaves a second deduction on the table in the same filing year.
