Cost segregation for Arizona property.
Short-term rentals, commercial buildings, and rental real estate across Arizona typically hold an estimated 15–35% of depreciable basis that reclassifies out of 39- or 27.5-year recovery into 5-, 7-, and 15-year property.

Why Arizona
A market built for reclassification.
Two of Arizona's biggest real-estate stories — a deep short-term-rental market and a fast-growing commercial metro — are exactly the property types where cost segregation surfaces the most. The desert adds to it: pools, hardscape, and xeriscape landscaping are 15-year land improvements that a study pulls out of the building basis.
Short-term rentals
Furnished Scottsdale and Sedona vacation rentals carry heavy 5- and 7-year personal property — furniture, appliances, decor — plus pools, decking, and desert landscaping at 15 years.
Commercial & medical
Phoenix-metro office, retail, medical office, and industrial generate the largest absolute reclassification dollars because the basis is bigger and the site work is extensive.
Long-term rentals
Single-family and small multifamily across the state still reclassify a meaningful share — flooring, cabinetry, appliances, and site improvements move to shorter lives.
Ranges vary widely by property type, finish density, and build-out — a furnished STR models differently from a warehouse. These are engineering estimate ranges, not promises; a study replaces them with documented component detail.

About these figures. Representative example, not a client result. Reclassification percentages are engineering estimates; year-1 figures are modeled federal tax estimates that depend on the §481(a) computation, the bonus rate for the placed-in-service date (2025 is a split year — 40% before January 20, 100% after), Arizona conformity, §469 passive-activity and material-participation rules, and entity structure. Compare with the cost segregation calculator or a sample study at Cost Seg Smart. Ranges, not promises.

Questions
Asked by Arizona owners.
Does cost segregation work on Arizona short-term rentals?
+
Yes. Furnished short-term rentals in markets like Scottsdale and Sedona carry a high share of 5- and 7-year personal property (furniture, fixtures, appliances, decor) plus 15-year land improvements (pools, decking, hardscape, desert landscaping), so they often reclassify a larger share of basis than a long-term rental. Whether the accelerated losses are usable this year depends on §469 participation rules — confirm with your CPA.
How does Arizona tax treat the accelerated depreciation?
+
Cost segregation is a federal reclassification. Arizona’s treatment of federal accelerated and bonus depreciation can differ from the federal result, and state conformity changes over time — confirm the Arizona effect for your return with your CPA. Every figure shown here is a modeled federal estimate.
I own commercial property in Phoenix — is a study worth it?
+
Often, yes. Commercial property generates the largest absolute reclassification dollars because the basis is bigger — office, retail, medical office, and industrial in the Phoenix metro all carry meaningful site work and specialty systems. The math depends on basis, the bonus rate for your placed-in-service date, and how §469 applies; run your specific property at costsegsmart.com rather than relying on a rule of thumb.
Does the property have to be in Arizona?
+
Cost segregation is a federal method that applies to income-producing property anywhere. This page focuses on Arizona because of its short-term-rental and commercial markets, but the same engineering-based approach applies nationwide — studies are delivered by Cost Seg Smart LLC.
