Data Center Zoning in Virginia and West Virginia After Loudoun’s 2025 Change

On March 18, 2025, Loudoun County ended by-right data center development, moving new projects into a special exception process with public hearings and a discretionary vote. That single change reshaped diligence in the largest data center market in the world, and West Virginia moved in the opposite direction the same year. This is my deep look at data center zoning across Virginia and West Virginia after Loudoun’s 2025 change.

Zoning used to be the quiet part of a Loudoun data center deal, because so much was approved by right. That is over. The entitlement path is now discretionary, the recorded conditions on a parcel matter more than ever, and the two states have split in opposite directions. Here is what changed, and where my lane sits within it.

What Loudoun changed in 2025

On March 18, 2025, the Loudoun County Board of Supervisors voted seven to two to end by-right data center development. Through a zoning ordinance amendment and a comprehensive plan amendment, data centers went from an administratively approved use in the districts where they were previously by-right, including the Industrial Park, General Industry, and Mineral Resources-Heavy Industry districts, to a use that now requires a special exception. The comprehensive plan amendment reclassified data centers as a conditional use rather than a core or complementary one. This is the single most consequential land use change for buyers in the largest data center market in the world. For years, much of Loudoun’s data center growth was approved at staff level, because data centers were treated as an office use until a 2014 amendment defined them and then permitted them by right in several districts. That era ended in March 2025. The county has said it cannot impose a moratorium, because Virginia law requires each application to be considered on its own merits, but the default path is now legislative rather than administrative.

What special exception means for your timeline

A by-right project was reviewed administratively through the site plan process. A special exception is a legislative process: staff review, then public hearings before both the Planning Commission and the Board of Supervisors, then a discretionary vote. That is a longer, less certain path, and it invites conditions. The practical effect for a buyer is that entitlement risk and timeline now sit squarely inside diligence, and a site’s zoning status is no longer a box to check but a question to answer. This is land use work, and it belongs to your land use counsel, who will run the special exception. My lane is the recorded layer that the entitlement rides on, and I make sure the title reflects every recorded proffer, condition, easement, and restriction that a special exception review will surface or rely on.

The grandfathering line, and why the date and the setback matter

The county adopted a grandfathering resolution that lets certain applications accepted before February 12, 2025 continue under administrative review without a special exception, but only for projects more than five hundred feet from residential units, and only if the application is diligently pursued with no substantial modification. A substantial modification is defined in part as an increase of more than five percent in the proposed square footage. Whether a specific site is grandfathered, and whether a planned change would forfeit that status, is a fact-specific question with real consequences for value and timeline. For a buyer, the grandfathering status of a pending application can be a central term of the deal. I confirm what the record shows about the application and any recorded conditions tied to it, and your land use counsel confirms the grandfathering status and what would jeopardize it.

Proffers and conditions run with the land, not with the seller

Whatever a prior owner agreed to in a rezoning or special exception is recorded against the land and binds you, regardless of what the seller remembers or discloses. Proffers can cap density, dictate building height and setbacks, require buffers and screening, limit noise, and impose design and phasing conditions. On a data center site those conditions can directly constrain the build you priced. A recorded proffer that limits the use is not the seller’s problem after closing. It is yours. This is exactly the recorded layer I read on every file. I surface the proffers, conditions, declarations, and restrictive covenants in the record so the limits on the property are known before closing rather than discovered after, and I flag anything that appears to conflict with your intended build for your land use counsel to evaluate.

Beyond Loudoun: the trend across Northern Virginia

Loudoun is the headline, but it is not alone. Prince William and other Northern Virginia jurisdictions have tightened data center review, added standards, and increased scrutiny of noise, buffers, and proximity to homes and historic and environmental resources. The direction of travel across the region is toward more discretionary review, not less. For a buyer, that means the assumption that a data center is permitted somewhere it was once routine no longer holds without checking the current ordinance and the recorded conditions on the specific parcel.

West Virginia moved the other way

While Northern Virginia added review, West Virginia reduced it for qualifying projects. The 2025 Power Generation and Consumption Act, House Bill 2014, prohibits counties and municipalities from enacting or enforcing ordinances that would prohibit or hinder certified data center and microgrid districts, and it routes qualifying projects through a state certification process rather than the usual local approvals. It also changes how the property is taxed, moving assessment of certified data center property to the state Board of Public Works with a statutory distribution formula. That is a very different posture from Loudoun’s, and it changes what diligence looks like on a West Virginia site. The recorded rights, the certification, and the tax treatment all need to be confirmed together. I read the recorded layer and coordinate the certification and the state tax framework with your West Virginia counsel.
