The Pennsylvania Association of Realtors published guidance on August 28 addressing a question that keeps coming up at kitchen tables across Bucks County. Data centers are not listed anywhere on the state seller disclosure form. There is no box to check.
Pennsylvania seller disclosure data center questions still reach sellers through a different door. Known material defects. West Rockhill Township is drafting a third version of its data center ordinance ahead of a September 16 supervisors meeting.
How the Disclosure Law Actually Works
The Real Estate Seller Disclosure Law requires sellers to disclose known material defects in the property being sold. That phrase carries two limits worth understanding. The defect must be material, meaning it has a significant adverse effect on the value of the property. And the seller must actually know about it.
Pennsylvania courts have read the law narrowly and consistently. The duty attaches to the condition of the property itself. It does not extend to every fact a buyer might find interesting about the surrounding area. A proposed facility two miles away is not a defect in your foundation.
That distinction is where data centers land. A building across the township line is off site. It is not a condition of your house. Facts that a data center generates are different. A documented change in your well water, a recorded easement, a noise complaint you filed with the township: those are conditions of your property, and they can carry a duty.
What Pennsylvania Seller Disclosure Data Center Rules Actually Require
The honest answer satisfies neither side. Sellers do not have to research every zoning application filed in the township. Buyers are not left blind either. Both things can be true.
Set that against what the numbers show right now. The average Bucks County home value is $530,927, up 3.3% over the past year, and homes go to pending in around seven days, per Zillow data through July 31, 2026.
Seven days is not enough time for most buyers to read a township agenda. Speed cuts both ways. The seller who answers the form carefully today avoids the phone call two years from now.
Why This Lands on Sellers Before Anyone Else
Sellers sign the form. Buyers read it. That order matters, because the disclosure document is the first written record either side creates, and it is the one a court looks at later. Pennsylvania seller disclosure data center questions will surface in that record long before they surface in a courtroom.
The practical risk is not that a seller hides a data center. The practical risk is that a seller answers a question too fast. The form asks about water quality, drainage, easements, and known material defects. If your well tested differently after nearby construction began, that belongs on the form regardless of what caused it. If a transmission easement was recorded on your parcel, that belongs on the form. Reasonable people land differently on how much context to add beyond the required answer.
Nothing about this is unique to West Rockhill. Falls Township and Morrisville froze parts of their zoning to write data center rules. Upper Merion rejected a project outright. If you own in a township where any of this is live, tell your neighbor who is thinking about listing next spring.
What This Means for You
If you are selling, pull your own records before you fill out the form. Well test results, any correspondence with the township, any easement recorded against your deed. Answer what you know and do not speculate about what you do not. If you are buying, the disclosure form is a floor and not a ceiling. Check the township zoning agenda yourself, and check the two townships that border your target, because noise and traffic do not stop at a municipal line.
Most of the anxiety here comes from not knowing what is actually required, and the answer is narrower than the rumor. A careful disclosure protects the seller more than it exposes them. If you are weighing a move in central Bucks, the Chalfont market gives you a useful read on how quickly well presented homes are still moving.

Frequently Asked Questions About Data Centers and Seller Disclosure
Do I have to disclose a data center near my home?
Not as a standalone item. The Pennsylvania seller disclosure form has no data center question, and an off site facility is not a defect in your property. Conditions on your own parcel are a different matter and do carry a duty.
Does a nearby data center lower my home value?
No local data supports a clean answer yet. Bucks County home values averaged $530,927 in July 2026, up 3.3% over the year, with homes going to pending in around seven days. The county market has not slowed.
Can a buyer back out over a data center?
A buyer can walk during an inspection or contingency period for almost any reason those terms allow. Backing out after closing requires proving a seller knew about a material defect and concealed it. That is a much higher bar.
What counts as a material defect in Pennsylvania?
A problem with the property that has a significant adverse effect on its value or presents an unreasonable risk to people on it. Off site land use does not qualify. Well contamination, structural issues, and recorded easements can.
