What Gets Reclassified

A cost segregation study identifies building components that can be depreciated over 5, 7, or 15 years instead of the standard 27.5 or 39 years. In Arizona, typical reclassification rates are 25-38% of building value.

Common Property Types
Single-Family DetachedStucco/Block ConstructionTownhomesCasitas/Guest Houses
Arizona's desert construction (stucco over block, tile roofs, extensive HVAC, pool equipment, hardscaping) creates strong reclassification opportunities. Properties with pools, outdoor living areas, and detached casitas often yield above-average cost seg percentages.

The math: A $395K property with 75% building value and 30% reclassification yields ~$33K in Year 1 federal tax savings at the 37% bracket — significantly more ROI than traditional studies costing $5,000-$10,000+.

Housing Stock Advantage

With a median build year of 1996, Arizona's housing stock has identifiable components (HVAC, electrical, plumbing, landscaping) that are strong candidates for accelerated depreciation.

Full Conformity
Arizona Bonus Depreciation Conformity

Arizona fully conforms to IRC Section 168(k), allowing investors to claim 100% first-year bonus depreciation at both the federal and state level. Combined with AZ's flat 2.5% income tax and LPV assessment cap, cost seg reclassifications generate immediate dual-layer tax savings.

What This Means for Your Investment: Full conformity combined with Arizona's flat 2.5% income tax means cost seg benefits flow through to both federal and state returns in Year 1. The low state rate keeps more money in your pocket from other income as well.

Section 179 Expensing
State ConformityConforms

AZ's full Section 179 conformity lets investors expense qualifying components up to the federal limit. This pairs well with cost seg for mixed-use properties where certain equipment or fixtures qualify independently.

Key Takeaway

A $395K property with a $296K depreciable basis and 30% cost seg reclassification yields ~$32.9K in federal tax savings PLUS ~$2.2K in AZ state tax savings in Year 1 — a total of ~$35.1K with one of the lowest tax burdens in the Sun Belt.

Bottom Line

Arizona is a full-conformity state with one of the lowest flat tax rates in the country. Every dollar of federal bonus depreciation flows through to your AZ state return. The combination of full conformity + 2.5% flat rate + no transfer tax makes AZ among the most investor-friendly states overall.

Property Tax Details

Arizona uses a dual assessment system — residential properties are assessed at 10% of full cash value (Limited Property Value). Effective rates vary by county: Maricopa (Phoenix) ~0.59%, Pima (Tucson) ~0.94%.

MethodFull Cash Value with Limited Property Value (LPV) cap
Reassessment CycleAnnually
Assessment BodyCounty Assessor
Appeal WindowWithin 60 days of Notice of Value (typically Jan-Mar)
Appeal Success Likelihood
Moderate
LowModerateGoodVery High

Arizona's LPV system caps annual assessed value increases at 5%, reducing over-assessment risk. Appeals are filed with the County Assessor and can escalate to the State Board of Equalization. The dual-value system (FCV vs LPV) means most investors focus on LPV appeals.

Depreciable Basis

Land vs. Building Value in Arizona

The land-to-building ratio directly impacts your cost segregation benefit — only the building portion is depreciable. Here is how Arizona breaks down by region.

Statewide Average
Building (Depreciable)75%
Land (Non-Depreciable)25%
75%
Depreciable Basis
Breakdown by Region
Phoenix Metro (Scottsdale/Paradise Valley)
70% Building

Premium land values in Scottsdale and Paradise Valley reduce depreciable basis. Target suburban areas for better ratios.

Phoenix Metro (Mesa/Gilbert/Chandler)
78% Building

East Valley suburbs offer strong building ratios with newer construction ideal for cost seg.

Tucson Metro
80% Building

More affordable land values create favorable cost seg economics in Arizona's second-largest metro.

Flagstaff / Prescott
72% Building

Mountain communities command land premiums for views and limited buildable terrain.

Rural / Southern AZ
85% Building

Lowest land costs in the state, but smaller rental markets limit demand.

Investor Takeaway

East Valley Phoenix suburbs (Mesa, Gilbert, Chandler) offer the best combination of strong rental demand and favorable 78% building ratios. Tucson at 80% building values provides a more affordable entry point. Avoid Scottsdale for cost seg optimization — the 30% land value significantly reduces your depreciable basis.

Primary Risk Drivers
1
Monsoon Storms & Dust (Haboobs)
Arizona's summer monsoon season brings violent thunderstorms, flash flooding, and dust storms that damage roofs, windows, and HVAC systems.
2
Wildfire Risk
Northern Arizona and mountain communities face increasing wildfire risk. Some insurers are restricting coverage in high-risk zones near Flagstaff and Prescott.
3
Extreme Heat
Sustained 110°F+ temperatures stress HVAC systems, roofing materials, and building envelopes. Heat-related equipment failures drive claims.
Coverage Recommendations

Flood insurance for properties in wash/arroyo flood zones (NFIP or private)
Extended HVAC coverage given extreme heat stress on cooling systems
Umbrella liability policy ($1M+) for rental properties
Cost Seg + Insurance Connection

A cost seg study documents individual building components including HVAC systems, pool equipment, and hardscaping that face Arizona's harsh climate. This documentation supports accurate replacement cost estimates and helps ensure your insurance coverage matches actual rebuild costs.
