Prince William County's Data Center Zoning Vote: What It Means for Homeowners and Buyers

This week, Prince William County is considering one of the most consequential land-use decisions in years: whether to end by-right data center development and sharply shrink the county's Data Center Opportunity Zone Overlay District. The Board of County Supervisors was scheduled to take up the zoning text amendment at its Tuesday, September 22 meeting at the County Complex in Woodbridge, following a 5-2 recommendation from the Planning Commission on September 9. If you own a home near the affected corridors, or if you are shopping for one in western Prince William County, this decision shapes the long view of property values, schools, open space, and daily life. Here is what is actually on the table, what the latest market data shows, and how I am advising clients to think about it.

What the County Is Deciding

The amendment before the Board, designated DPA2026-00006, rewrites the rules for the Data Center Opportunity Zone Overlay District (DCOZOD), the county code area that currently allows data centers to be built by right, meaning without a special use permit or individual Board approval. The Planning Commission's recommendation, which staff largely endorsed with amendments, does two things. First, it would end by-right data center development: any new data center would need a special use permit and Board approval, giving the county a direct say in every future project. Second, it would downsize the overlay district from roughly 9,700 acres to about 3,500 acres, redefining the boundaries to limit them to parcels that meet specific criteria and removing sites such as the Jiffy Lube Live area and planned school land from by-right development.

This is a genuine turning point. For years, Prince William has positioned itself as the next frontier of data center growth after neighboring Loudoun County, the region known as Data Center Alley, and the overlay district has been a centerpiece of that strategy. The public debate has been equally about the benefits and the costs: tax revenue and construction jobs on one side, and concerns about noise, power infrastructure, traffic, and the character of rural and suburban neighborhoods on the other. A related matter, Dominion Energy's Vint Hill Substation expansion near Nokesville, was deferred for 90 days, so the full picture of energy infrastructure in the county remains in motion alongside the zoning question.

Why It Matters for Home Values

Zoning is the quiet force behind a home's value. It determines what can be built next door, how much open space surrounds a neighborhood, and how a community grows over a decade. The outcome of this vote will not change tomorrow's sales, but it matters deeply for the long view, which is how I encourage my clients to think about buying a home in the first place.

For buyers looking at western Prince William County communities like Nokesville, Gainesville, and Haymarket, the practical question is: what kind of growth will surround this neighborhood over the next 10 to 20 years? Ending by-right data centers means every future project gets a public hearing and an individual vote, which gives residents and future homeowners a meaningful voice. Shrinking the overlay district narrows the geography where data centers could be proposed at all. Both outcomes reduce uncertainty for buyers, and certainty has value. For sellers, the takeaway is subtler but real: neighborhoods within the current overlay footprint have carried an undercurrent of land-use uncertainty, and this vote starts to resolve it one way or another.

I am not going to take sides on the merits of data centers themselves, and I want to be clear that the Board's decision had not been announced as of this writing. My job is to make sure my clients understand what the decision changes, whatever direction it goes: the rules that govern future development, the sites eligible for it, and the process communities will use to weigh in. That is the part that shapes home values over time.

Where the Market Stands This Week

Away from the county chambers, the fall market is settling into its routine. The Federal Reserve voted 12-0 on September 16 to raise its benchmark rate by 25 basis points to 3.75% to 4.00%, its first hike since 2023, and Chair Kevin Warsh signaled the committee could move again. The reaction came quickly in mortgage rates: Freddie Mac's Primary Mortgage Market Survey for the week ending September 17 averaged 6.95% for the 30-year fixed, up from 6.76% the prior week and the fourth consecutive weekly increase, with the 15-year fixed averaging 6.26%. Daily rate trackers have pushed toward and above 7%, and analysts have described the path to lower mortgage rates as highly uncertain with the Fed pointing to more tightening to come.

The inventory story that defined the summer continues. NVAR's August 2026 market statistics, released September 14, show region-wide closed sales of 1,324, down 8.0% year-over-year, with the median sold price up about 2% and condos and attached homes leading inventory growth. In Prince William County, the most recent verified county-level release is PWAR's June 2026 data: 663 closed sales, up 18.2% year-over-year, with 935 active listings at month end, up 21% and the highest June inventory in five years, plus 623 pending sales and 641 new listings. PWAR's August figures had not been published as of this writing, and I will post them the day they arrive on my market report page.

A Full Fall Calendar Across the County

While the county deliberates, the community calendar keeps rolling. This weekend brings two of Manassas's signature celebrations: the Manassas Latino Festival on Saturday, September 26, 11 AM to 6 PM at the Harris Pavilion, billed as the region's longest-running Hispanic and Latino family festival with live music, dance, and dozens of vendors, and the NVA Thai Street Food & Culture Festival on Sunday, September 27, 10 AM to 5 PM on the Manassas Museum Lawn, with authentic Thai street food, dance, and crafts. Both are free.

The first Saturday of October is a double feature: the 43rd annual Historic Manassas Fall Jubilee on October 3, 10 AM to 5 PM in Old Town, with more than 100 craft and community booths, live music, and kids' activities, and the Prince William County Fire-Rescue 3rd Annual Expo & Fall Festival the same day, noon to 5 PM at Pfitzner Stadium in Woodbridge, with fire truck tours, rescue demonstrations, and family activities. One scheduling note: after a September 4 incident at a downtown Manassas event, the city and Historic Manassas Inc. paused the October First Friday "Pumpkin Palooza" while they review downtown event safety, so check with organizers before planning around it. On the community pride front, UVA Health Prince William Medical Center earned the national Magnet designation, the highest nursing honor a hospital can receive, announced this week.

How I'm Advising Clients This Week

If you own a home in or near the current overlay district, keep an eye on the outcome in the coming days, and remember that no single vote rewrites the value of a well-located home in a strong school district with a short commute. If you are buying, especially in western Prince William County, this is a good moment to ask your agent questions about adjacent land use, county plans, and what is zoned around the neighborhoods you tour. And if you are selling this fall, price from data, not emotion: with rates near 7% and inventory at its highest level in years, presentation and realistic pricing are what win the day.

The fundamentals that drew us all to Northern Virginia have not changed: strong schools, solid commutes, a resilient job market, and a sense of community that shows up every weekend at festivals like the ones above. Real estate headlines come and go, but those are the things that hold value over time. Whether the vote, the rates, or the season has you thinking about a move, I would love to talk through what it means for your specific situation, with no pressure and no obligation, like family.
