Depreciating Renovations and Improvements to Your STR
No credit card required
Capital improvements to your STR must be depreciated over time—they cannot be deducted in full the year you pay for them, unlike ordinary repairs and maintenance. Under IRC §263 and §168, structural improvements are depreciated over 27.5 years, land improvements over 15 years, and personal property (appliances, equipment) over 5 years with 100% bonus depreciation available in 2026.
Capital Improvement vs. Repair: The Critical Distinction
Not every dollar you spend on your STR property is a capital improvement. The IRS distinguishes between repairs (fully deductible in the year incurred) and improvements (must be capitalized and depreciated). The general rule under the Tangible Property Regulations (Treas. Reg. §1.263(a)-3):
- Repairs and maintenance: Deductible immediately. Fixing a broken window, patching drywall, touching up paint, unclogging a drain.
- Capital improvements: Must be capitalized and depreciated. Work that betters, restores, or adapts a unit of property to a new or different use.
The IRS uses a "BAR" framework: work is a capital improvement if it Betters the property, Adapts it to a new use, or Restores it to working condition after it was worn out. Replacing every window in the house is a restoration (capital improvement). Replacing a single cracked window is maintenance (immediate deduction).

Structural Improvements: 27.5-Year Schedule
Structural improvements to a residential rental property are depreciated over 27.5 years, just like the original building. These are improvements that become part of the building structure or its integrated systems.
New Roof: 27.5-Year Example
Structural ImprovementNew roof installation in April 2026: $22,000. Starts depreciation in April 2026 under the mid-month convention.
Annual depreciation (full years): $22,000 ÷ 27.5 = $800/year
Consider: Make a partial disposition election to write off the old roof's remaining basis immediately
Land Improvements: 15-Year Schedule with Bonus Depreciation
Improvements to the land surrounding your STR—decks, patios, driveways, fencing, landscaping—are 15-year land improvements and qualify for 100% bonus depreciation in 2026. This is one of the highest-leverage categories for STR renovations because you can deduct the full cost immediately.
New Outdoor Deck
15-Year · 100% BonusNew wood deck installed June 2026: $18,500. The deck is attached to the land, not integrated into the building structure.
Without bonus (standard 15-yr MACRS): $1,850/year for 15 years
Tax savings difference at 30% rate: ~$5,550 additional savings in Year 1
Appliances and Personal Property: 5-Year with Bonus
When you renovate, pay close attention to appliances and personal property items installed as part of the project. These should be separated from the structural work on your invoices and depreciated at their shorter 5-year life with bonus depreciation available.
Kitchen Remodel: Breaking Out the Components
Mixed Asset ClassesFull kitchen renovation: $38,000 total invoice. Breaking it down correctly:
Appliances (refrigerator, dishwasher, range, microwave): $9,500 @ 5 yr + 100% bonus = $9,500 Year 1
Lighting fixtures (non-structural): $3,200 @ 5 yr + 100% bonus = $3,200 Year 1
Flooring (vinyl plank): $3,300 @ 5 yr + 100% bonus = $3,300 Year 1
Total Year 1 deduction: $800 + $9,500 + $3,200 + $3,300 = $16,800 vs. $1,382 if everything were lumped into 27.5-yr
Partial Disposition Election When Replacing Components
When you replace a structural component (a roof, HVAC system, windows), you can make a partial disposition election under Treas. Reg. §1.168(i)-8 to write off the remaining undepreciated basis of the old component immediately. This is covered in detail in our guide to partial disposition elections.
