Arizona's Water Crunch and Phoenix Housing Affordability: What It Could Mean

Sold By Ron and Jill Group | Phoenix Metro Real Estate | West Valley Specialists

Arizona's groundwater crisis is not a future problem --- it is already reshaping where homes get built, who can afford them, and how long buyers in the West Valley's fastest-growing submarkets may have to wait. The honest assessment is this: if your search is centered on Buckeye, Goodyear, or the outer fringes of Peoria, the water situation belongs in your decision framework alongside price and commute time.

The Terrain: What the Data Actually Shows

In June 2023, the Arizona Department of Water Resources published a revised groundwater model for the Phoenix Active Management Area. The model concluded that projected demand would outstrip legally available groundwater supply over a 100-year horizon. The result: a moratorium on issuing Certificates of Assured Water Supply for new subdivisions relying solely on local groundwater in areas not served by a designated water provider.

The submarkets hit hardest were Buckeye, Goodyear, and Queen Creek --- three of the highest-growth corridors in the metro. Buckeye in particular had been one of the last places in Maricopa County where a buyer could find a new home under $400,000. According to a 2025 analysis by Elliott D. Pollack and Company, more than a quarter of all Maricopa County home sales under $400,000 in a recent 12-month period occurred in Buckeye. Freeze that pipeline, and the affordability math changes fast.

Meanwhile, the broader housing picture adds pressure. Median home prices in Maricopa County climbed 65% between June 2019 and June 2025, landing near $474,000. A 2025 Morrison Institute report from ASU found that housing values increased roughly seven times faster than incomes between 2010 and 2023. Eviction court filings hit a record 106,587 in 2024. Arizona, once a benchmark for affordability, now sits above the national average cost of living.

In October 2025, Governor Hobbs announced a partial path forward. EPCOR became the first utility in 25 years to receive a new 100-year Alternative Designation of Assured Water Supply under a revised framework designed to balance growth with conservation. It is meaningful progress, but it applies to a fraction of the homes currently stalled --- and the broader legal battle between the Home Builders Association of Central Arizona and ADWR continues in the courts.

The Weather: What Buyers Are Actually Feeling

Most buyers researching the Phoenix market hear "water crisis" and immediately picture dry taps and evacuation orders. That is not the situation. Phoenix proper, Peoria, Glendale, Anthem, and Litchfield Park are all served by designated water providers and are largely insulated from the moratorium. The headline anxiety and the ground-level reality are not the same thing.

What the smart buyer should feel is not panic --- it is calibrated caution. The questions worth asking are about which specific developments in your target submarket hold a Certificate of Assured Water Supply, whether the builder is using Central Arizona Project water, reclaimed water, or another renewable source, and what the long-term infrastructure plan looks like. These are due diligence questions, not dealbreakers by default.

For sellers, the psychological weight lands differently. If your home is in an area where future new construction is constrained, limited supply can support values. But if resale buyers start associating the zip code with water uncertainty, that perception risk is real. Data from late 2025 shows that buyers who felt they overpaid at closing dropped to 8% --- nearly half the rate from two years prior --- suggesting the overall market has found more equilibrium. Whether that holds in affected submarkets depends heavily on how the ADWR litigation resolves.

Where the Moratorium Does and Does Not Apply

This distinction matters more than anything else in this conversation. Over 90% of the Phoenix metro population is served by a designated water provider --- Phoenix, Peoria, Glendale, Scottsdale, Tempe, Chandler, Gilbert, Mesa, Surprise, and Litchfield Park among them. Development in those cities was never subject to the moratorium. If you are buying a resale home or a new build within those city limits, the groundwater ruling is largely background noise, not a direct variable in your transaction.

The moratorium affects new subdivisions in areas without a designated water provider that planned to use local groundwater for their Certificate of Assured Water Supply. The practical impact concentrates in outer Buckeye, parts of Queen Creek, and some developing parcels on the western edge of Goodyear. Projects that had already received a CAWS before the ruling --- potentially covering over 80,000 lots according to Arizona Water Blueprint research --- can continue. Teravalis, the large master-planned community in western Buckeye, is an example: units in the CAWS-certified phase are proceeding, and model homes were open as of late 2025.

What This Means for Affordability in the West Valley

The cost pressure works in two directions. On the supply side, fewer buildable lots in affordable submarkets means less competition for buyers who do secure available inventory --- but also less selection overall. Builders who are moving forward must now source water from more expensive alternatives: imported renewable water, reclaimed water, or Central Arizona Project allocations. That cost does not disappear. It transfers to the sticker price of the home.

The City of Phoenix is targeting the creation or preservation of 50,000 homes by 2030 under its Housing Phoenix Plan, and the state passed four housing bills in 2024 aimed at expanding supply and reducing barriers. But legislative and municipal housing production takes years to translate into available units. In the near term, buyers who need to be at or under $400,000 and are looking at new construction in outer Buckeye or western Goodyear will feel the squeeze most directly.

For buyers in the $450,000 to $900,000 range, the picture is less constrained. Established West Valley communities including Anthem, Peoria, and Litchfield Park offer strong inventory, functioning water infrastructure, and no direct exposure to the moratorium. New construction options in those areas from major builders have not been meaningfully impacted. The affordability ceiling gets tighter as you move toward the exurban edge, not the established core.

The Legal Landscape and What Comes Next

The Goldwater Institute filed suit against ADWR in early 2025 on behalf of the Home Builders Association of Central Arizona, challenging both the groundwater modeling methodology and ADWR's authority to impose the moratorium. A separate lawsuit joined by the Arizona Senate and House challenged the requirement that cities importing renewable water reduce groundwater use by 25%. ADWR moved to dismiss the Goldwater suit; as of early 2026, that litigation is unresolved.

Two scenarios are worth mapping. If the courts uphold ADWR's authority, the moratorium framework likely becomes a permanent structural constraint on outer-suburban development, pushing density inward over time and solidifying water-secured submarkets as the path of least resistance for large builders. If the courts rule against ADWR, more certificates could be issued --- but ADWR and the governor's office have indicated that "water first, then development" remains the governing principle. A legal win for developers does not automatically reopen the spigot.

The EPCOR alternative designation framework announced in October 2025 signals the most pragmatic path forward: builders who secure renewable water partnerships can move forward. Expect more utility deals structured around CAP allocations and reclaimed water to emerge in 2026 as developers adapt to the new operating environment.

The Tactical Read for Buyers and Sellers in Early 2026

If you are a buyer targeting the West Valley with a budget between $450,000 and $750,000, the water situation does not close off your options --- it focuses them. Anthem, Peoria, Glendale, and Litchfield Park all operate within established city water systems. New construction in those submarkets has not been materially disrupted. Resale inventory in those markets offers additional options with known infrastructure.

If your budget requires sub-$400,000 and you are looking at new construction in outer Buckeye or western Goodyear, the due diligence question is direct: ask the builder which water source was used to secure the CAWS and whether the project is within an already-certified phase. A builder who cannot answer that clearly is a builder worth walking away from.

For sellers in water-stable submarkets, the moratorium may quietly work in your favor. Constrained future supply in adjacent areas can support pricing in established communities. That dynamic is worth understanding before you price and before you negotiate.
