Arizona Lured Data Centers With Tax Breaks and Cheap Water, Now the Bill Is Coming Due

By Scott Bryant | Bryant Real Estate

Arizona has spent years positioning itself as a business-friendly alternative to California, lower taxes, newer homes, and a more affordable cost of living. That strategy helped fuel explosive growth, including a surge in large-scale data centers across the Phoenix metro area.

Now, as water constraints tighten and utility costs rise, the state is reconsidering whether those incentives still make sense and Arizona home buyers and sellers should be paying attention.

Why Arizona Is Rethinking Data Center Incentives

Governor Katie Hobbs has proposed eliminating Arizona’s data center tax exemptions and charging data centers more for the water they use. Her reasoning is simple: residents are facing higher water bills and stricter conservation rules, while one of the state’s fastest-growing industries has historically paid far less than its proportional share.

The average Arizona household effectively pays about one cent per gallon for water. If large data centers paid similar rates, Arizona could generate millions each year for conservation and long-term water planning tied to the Colorado River supply.

For buyers and sellers, this matters because water costs directly affect housing affordability, both in monthly expenses and long-term property values.

Water Costs and Housing Affordability in Arizona

Water and wastewater bills across Arizona are already projected to rise faster than inflation. As cities invest in infrastructure and conservation, those costs are passed on to homeowners.

Here’s how that impacts the housing market:

• Buyers factor higher utility costs into affordability and purchasing decisions
• Sellers may face more scrutiny on water usage, landscaping, and efficiency
• Investors evaluate long-term sustainability when choosing markets
• HOA communities may raise dues as water and infrastructure costs increase

In short, water is becoming a bigger line item in the cost of homeownership.

The Data Center Boom in Metro Phoenix

Phoenix is now one of the largest data center hubs in the country, with more than 160 facilities operating across the Valley. Companies like Microsoft, Blackstone, and Aligned Data Centers have chosen Arizona in part because of long-standing tax incentives and predictable operating costs.

But data centers are water-intensive. Some individual facilities use as much water annually as hundreds of single-family homes. That scale has sparked community resistance, including recent city council rejections of new data center proposals.

Industry Pushback and the Political Reality

Business leaders argue that data centers provide stable property tax revenue, create high-paying jobs, and help fund infrastructure improvements that benefit surrounding communities. In other states, data center tax revenue has even been used to support affordable housing initiatives.

They also point out a political reality: rolling back tax incentives is difficult, and Arizona requires a supermajority vote to eliminate existing exemptions.

That means any changes will likely be gradual, but the direction of the conversation is clear.

What Arizona Home Buyers Should Know

If you’re buying a home in Arizona, especially in Phoenix, Scottsdale, or surrounding suburbs:

• Expect utility costs to play a bigger role in affordability
• Water-efficient homes, landscaping, and newer infrastructure will matter more
• Communities with strong long-term water planning may hold value better

Sustainability is increasingly tied to resale value.

What Arizona Home Sellers Should Know

For sellers, especially in established neighborhoods:

• Water-efficient upgrades can be a selling advantage
• Xeriscaping and efficient irrigation are no longer just aesthetic choices
• Buyers are asking smarter questions about long-term costs

Homes that align with Arizona’s future, not its past, will stand out.

The Bigger Picture for Arizona Real Estate

Data centers are now part of Arizona’s economic fabric. The real question isn’t whether they belong here—but whether they help support the infrastructure and resources that make Arizona livable.

How the state answers that question will influence:

• Housing affordability
• Utility costs
• Long-term property values
• Growth patterns across metro Phoenix
