Cost Segregation in Arizona

Cost segregation studies for Arizona property owners.

Arizona has become one of the most active rental and investment property markets in the country, from Scottsdale vacation homes to Phoenix apartment communities to the vast new facilities rising across the Valley. A great deal of that real estate is depreciating far slower than federal law allows. Cost Seg America is an American company with a 100% U.S.-based team. For 24 years we have helped property owners accelerate federal depreciation, free up cash, and put their buildings to work. We make it simple, we put it in writing, and we stand behind every study.

Why Arizona owners are choosing Cost Seg America

If you are shopping your cost segregation study, read this first.

More and more Arizona investment property owners are turning to Cost Seg America, and once they understand what separates one study from another, it is not hard to see why.

Here is what the low-price firms do not put in their advertising. Many studies priced under $2,900 have minimal engineering, the gaps are filled in with modeling software, and in many cases the work is outsourced overseas. Ask yourself a simple question: when a study is run through software by someone who has never set foot in the United States, whose pocket is being padded? It is not yours.

A cheap study is not a discount. It is a study that quietly leaves your money behind.

$60K–$150K
On a typical $1 million property, that is roughly how much more a fully engineered Cost Seg America study uncovers compared to a cheap, software-driven one. That is real money, federal deductions you were entitled to, that a shortcut study simply never found.

When you pay for a cost segregation study, you should get the study you thought you were paying for. A real one. Engineered component by component, by analysts who do the work properly and stand behind it.

Cost Seg America is an American company. Every study is performed by a 100% U.S.-based team, never outsourced, never shortcut with software. We have completed more than 16,000 studies over 24 years, supported clients through more than 125 IRS audits with zero losses, and never returned a dollar to the IRS. When a property owner trusts us with their building, American analysts do the work, and American analysts answer for it.

American analysts. American work. Done right.
Why cost segregation matters in Arizona…

Arizona is one of the great rental-property markets in America.

Few states have grown the way Arizona has. The Valley of the Sun. Phoenix, Mesa, Chandler, Gilbert, Glendale, and the rest of Maricopa County, has absorbed an extraordinary wave of new residents, and rental housing has been built to meet them: sprawling apartment communities, build-to-rent neighborhoods, and tens of thousands of single-family rental homes. Layered on top of that is one of the country's most active short-term rental markets, concentrated in Scottsdale, Sedona, and the resort corridors, where furnished vacation homes change hands at premium values. And alongside the housing boom, Arizona has drawn enormous semiconductor, data center, and advanced-manufacturing investment, plus the resort and hospitality industry that has anchored the state's economy for generations.

Every one of those buildings has a depreciation schedule, and most are depreciating far more slowly than federal law allows. Cost segregation is the engineering-based strategy that corrects that. Rather than depreciating a building over 27.5 or 39 years, a cost segregation study identifies the components that can be reclassified into 5-, 7-, and 15-year property, accelerating federal deductions, front-loading cash flow, and putting capital back in the owner's hands when it is most useful.

Across every region and county, property owners are sitting on federal deductions they have not claimed. We typically find $200,000 to $450,000 in additional Year 1 deductions per $1 million of property value.

The Arizona properties we study most…

Built for the property types that define the Arizona market.

Arizona real estate is led by rental housing in all its forms, supported by resorts, industry, and a fast-growing commercial base. These are the Arizona property types where a cost segregation study most often delivers significant results, and residential rentals sit right at the top of the list.

Apartments & Residential Rentals
From single-family rentals to large apartment communities across the Valley, residential rental property holds flooring, cabinetry, appliances, and site improvements that reclassify strongly into short-life property.
Short-Term & Vacation Rentals
Furnished vacation homes in Scottsdale, Sedona, and the resort corridors carry finishes, furnishings, and site work that frequently qualify for accelerated depreciation.
Build-to-Rent Communities
Build-to-rent neighborhoods rising across the suburbs hold extensive site work, landscaping, and residential components suited to acceleration.
Industrial & Advanced Manufacturing
Arizona's semiconductor, data center, and advanced-manufacturing facilities carry heavy specialized electrical, process systems, and reinforced site work suited to a study.
Resorts & Hospitality
The resorts and hotels that have anchored Arizona for generations carry finishes, furnishings, lighting, pools, and extensive site improvements well suited to acceleration.
Office, Medical & Retail
Office, medical, and retail buildings across the metros contain electrical, HVAC, and interior buildouts that reclassify well.
What a study typically uncovers…

The numbers that make owners pay attention.

Every property is different, and the only accurate figure is the one we put in writing for your specific building. But across the thousands of studies we have completed, a clear pattern holds, and cost segregation is not only for large commercial buildings.

Typical Year 1 finding
$200K–$450K
in additional deductions per $1M of property value
From the high country around Flagstaff to the Sonoran Desert and the Tucson basin, across all 15 counties, Arizona property owners are sitting on federal deductions they have not claimed. We typically find $200,000 to $450,000 in additional Year 1 deductions per $1 million of property value.

Bonus depreciation
Why this matters now

Bonus depreciation makes this the right moment.

Recent federal legislation restored 100% bonus depreciation for qualifying property placed in service after January 19, 2025. For an Arizona property owner, that means the short-life components a cost segregation study identifies can often be deducted in full, in a single year, rather than spread across decades. With so much recent rental-home, apartment, and industrial construction across Arizona, pairing a study with bonus depreciation is one of the most powerful federal tax positions available right now, and the sooner a study is done, the sooner those deductions reach your return.

How a cost segregation study works…

Four steps. We handle the engineering.

01
Free proposal
Tell us about your property. Within 24 hours, we deliver a free, no-obligation proposal estimating your potential deductions.
02
Engineering analysis
Our 100% U.S.-based analysts perform a component-by-component engineering analysis of your property.
03
Your IRS-ready study
You receive a complete, fully documented, IRS-ready study, everything your tax professional needs to put the deductions to work, prepared and clearly explained.
04
Lifetime support
We stand behind every study for the life of the property, including lifetime audit support, at no additional charge. We do not hand you a document and disappear.

One note on filing: applying a completed study to your return is done through a Form 3115. In most cases your own CPA files it, it is standard work they already handle. If your CPA would rather not, we have a trusted partner CPA who can file it for a separate fee. Either way, it gets done, and you will know exactly what to expect up front.

The questions owners ask first…

Two honest concerns, answered directly.

“Won't a cost segregation study trigger an IRS audit?”
An engineering-based study does not, by itself, raise audit risk. What matters is the quality of the study. A fully engineered, properly documented study is a defensible tax position, the opposite of a red flag. Cost Seg America has supported clients through more than 125 IRS audits with zero losses, and nothing has ever been returned to the IRS.
“If this were worth it, wouldn't my CPA have told me?”
Not necessarily, and that is not a criticism of CPAs. Cost segregation is an engineering discipline, not an accounting one. It requires identifying and valuing building components, which is separate work from preparing a return. The best CPAs partner with cost segregation specialists for exactly that reason. We work alongside your CPA, never around them.

Cost segregation questions…

Answers for property owners.

Why is cost segregation valuable for Arizona property?
Arizona is one of the most active rental and investment property markets in the country, with apartment communities, build-to-rent neighborhoods, single-family rentals, short-term vacation rentals, resorts, and a fast-growing industrial base. These property types carry significant components that can be reclassified into shorter federal depreciation lives through an engineered cost segregation study.
Do Arizona residential and vacation rentals qualify for a cost segregation study?
Often, yes. Cost segregation is not only for large commercial buildings. Apartment communities, build-to-rent homes, single-family rentals, and furnished vacation properties all carry flooring, cabinetry, appliances, and site improvements that frequently qualify for accelerated federal depreciation. Most commercial and residential rental properties valued at $250,000 or more can benefit.
Can older Arizona buildings still qualify for a cost segregation study?
Yes. A lookback study can capture depreciation missed in prior years and apply it to a current return without amending old filings. With so much recent construction across the Valley, both new and established Arizona properties are strong candidates.
