There are 43 data centers in Clark County right now. Not proposed. Already built.

If you’re shopping for a home in Southwest Las Vegas, Henderson, or North Las Vegas, there’s a reasonable chance one of them is closer to the house you’re considering than you realize. And the question every buyer eventually asks me is the same one: is that a problem?

The honest answer is that it depends almost entirely on which project, and what stage of approval it’s sitting in. A grandfathered facility evaporating hundreds of millions of gallons a year is a completely different neighbor than a closed-loop building using a thousand gallons a day. Treating “data center nearby” as one single risk category is how buyers miss the actual story on a specific street.

Here’s how to tell the difference.

Why are data centers being built in Las Vegas?

Three reasons, and you need all three to understand the rest.

Land. Apex Industrial Park in North Las Vegas covers 18,000 acres near the I-15 and US 93 interchange, with roughly 5,000 still open for development. For a homebuilder, that’s unremarkable desert. For an operator who needs acreage and doesn’t care about curb appeal, it’s ideal.

Power. NV Energy’s Greenlink transmission project started at $2.5 billion and now sits at $4.2 billion. Roughly 80% of that new capacity is already committed to data center operators.

Tax policy. The Governor’s Office recently approved abatements worth $138.7 million to a single company for one North Las Vegas project.

Cheap land, locked-in electricity, and a state willing to cut the tax bill. That combination is why the valley keeps landing these projects.

Will data centers drain Las Vegas’s water supply?

This is the question everyone leads with, and in Southern Nevada it’s largely the wrong one.

Here’s how this valley works. Indoor water you use at home goes down the drain, through a treatment plant, out the Las Vegas Wash, and back into Lake Mead — and Southern Nevada earns return-flow credits for it. We’re permitted to draw more from the Colorado River because we put that water back. That mechanism is the reason this valley grew past two million people on the smallest river allocation of any of the seven basin states.

An older-style data center cools itself by evaporating water into the air. That gallon never returns to the Wash, never reaches Lake Mead, and never earns a credit. It’s gone — for everyone downstream.

The Southern Nevada Water Authority saw that coming and banned evaporative cooling in new commercial and industrial construction in 2023. Every data center built here since runs on a closed loop that recycles up to 99% of its water. The head of the water authority told state lawmakers this spring that data centers can be built in Southern Nevada without consuming additional water.

So if someone tells you data centers are about to drain Lake Mead, they’re describing a problem this valley addressed before most of the country recognized it.

There is one significant exception, and it’s in Henderson.

What about the Google data center in Henderson?

Google’s Henderson facility opened in 2020 — before the ban — so it’s grandfathered in and still uses evaporative cooling. Google’s own environmental reporting puts its 2024 consumption above 200 million gallons.

That single building has become the reference point for every data center argument in Southern Nevada, and it’s why Henderson residents are the most engaged on this issue in the valley.

In November 2025, Henderson’s Planning Commission approved a five-building, 157-acre project from developer Trammell Crow. Months later, Mayor Michelle Romero indicated publicly that the project likely wasn’t moving forward. She then proposed a 180-day moratorium on new data center construction. The council voted it down in July and chose to rewrite the city’s code instead — any future data center in Henderson will require an individually negotiated development agreement with the city.

What this means if you’re buying in Henderson: the rules governing what can be built next to you are being written this year. If you’re planning to sell within the next two or three years, that uncertainty is worth factoring in. If you’re staying a decade, it likely resolves long before it affects you.

Is Southwest Las Vegas affected?

If you’re near Decatur Boulevard and the 215 Beltway, you already live beside the largest cluster of data center space in Southern Nevada. Switch operates more than two million square feet there.

In June 2026, Clark County approved a 56,800-square-foot expansion on nine acres near Warm Springs Road, adjacent to the existing campus. It runs on a closed loop and is expected to use roughly 1,000 gallons of water per day — about what three households use.

The approval wasn’t frictionless. More than a dozen residents raised concerns about noise, energy use, and cumulative growth in the corridor, and Switch withdrew a request to skip perimeter tree planting after commissioners signaled they wouldn’t support it.

What this means if you’re buying in Southwest Las Vegas: the story here isn’t water. It’s an established employer that keeps expanding, and neighbors paying close attention to how much bigger it gets.

What’s happening at Apex in North Las Vegas?

Nothing is built yet — but the land positions tell you where this is headed.

Switch owns more than 300 acres at Apex after two purchases totaling $180.5 million. Novva acquired nearly 205 acres for approximately $181 million the year prior. That’s over 500 acres between two companies, with no buildings.

This is land banking, the same practice homebuilders use when they secure lots years ahead of a growth cycle. It means the tax base and job growth people associate with data centers hasn’t materialized in North Las Vegas yet.

What this means if you’re buying near Apex: you’re purchasing ahead of the story rather than after it. That can work well if values rise once projects break ground, or it can mean waiting years for benefits that haven’t arrived.

The real fight in Nevada isn’t water — it’s land

While the water conversation was playing out, something more consequential happened outside Boulder City.

A Texas developer received federal approval to build the first data center ever authorized on Bureau of Land Management land in the United States — on an 80-plus-acre parcel about three miles from the city. The developer already held a federal permit for a solar farm and asked to amend it. The BLM’s Las Vegas field office determined the existing environmental review was close enough to cover a data center.

Boulder City disagreed. The City Council voted unanimously in July to appeal, joined by the Center for Biological Diversity and the Sierra Club. Congresswoman Dina Titus demanded answers from federal land managers.

On September 1, 2026, an administrative judge halted the project, ruling that the BLM acted arbitrarily in treating a data center as substantially the same as a solar plant. Construction is frozen while the appeal proceeds.

More than 80% of Nevada is federally owned. Clark County has limited industrial land remaining, and without a major lands bill, little more is coming. So when a federal agency decides whether data centers can occupy public land — and how much environmental review that requires — it’s setting the terms for development across the entire state. Not just for server farms. For everything, including housing.

Boulder City Question 1 on the November ballot

On November 3, 2026, Boulder City voters decide Question 1: whether data center facilities should become an approved land use within part of the Eldorado Valley Transfer Area.

Boulder City purchased roughly 100,000 acres there in 1995, and the city charter prohibits development without voter approval. The measure would open approximately 14,000 of those acres.

It goes to voters in a difficult climate. A statewide poll conducted the first week of September found 59% of Nevada voters oppose data centers being built in or near their community, against 31% in support — with opposition high among Democrats and independents and Republicans nearly evenly split.

Boulder City isn’t alone. Nye County banned data centers outright in an over-appropriated water basin in August.

What buyers and sellers should actually do

Before you write an offer on a home anywhere near one of these projects, find out three things: which company, what cooling system, and what stage of approval.

A closed-loop facility next to an established campus is a stable neighbor with jobs and tax revenue attached. A project sitting inside an unresolved regulatory fight can leave a neighborhood in limbo for a year or more. And a land bank is a promise that may not arrive for a decade.

Those aren’t the same risk, and they shouldn’t be priced the same way.

If you’re considering a home in Southwest Las Vegas, Henderson, North Las Vegas, or Boulder City and want to know exactly what’s proposed, approved, or being contested near a specific street — that’s research I do before I ever put a buyer in a car.
