The Line Virginia's Disclosure Form Still Doesn't Have

Virginia's seller disclosure form grew longer this year. As of July 1, 2026, the state's Residential Property Disclosure Statement carries new named categories for resource protection areas under the Chesapeake Bay Preservation Act and for historic district ordinances, joining an existing list that already covers things like lead pipes, defective drywall, and wastewater systems. Each comes with the same boilerplate: the owner makes no representation, and the purchaser is advised to do their own homework. What the form still doesn't have, in this update or any before it, is a line for underground heating oil tanks.
That gap matters more in McLean than in most Northern Virginia zip codes, because McLean has more houses old enough to have one.
Oil furnaces paired with underground storage tanks were the standard way to heat a house across Virginia from the years after World War II until roughly 1975, when natural gas conversion became widespread. McLean's oldest neighborhoods sit squarely in that window. Chesterbrook and parts of Old Dominion Gardens date to the 1940s and 1950s, built originally for military officers and government executives. Larger colonials in Langley Forest, Langley Oaks, and Hansborough followed in the 1970s through the 1990s, straddling the transition from oil to gas. A McLean HVAC contractor that has served Fairfax County since 1957 still lists active oil boiler service calls in Langley Farms and Chain Bridge Forest, describing homes where the original burner still feeds radiators or baseboard piping that predates every renovation the house has been through since.
None of that means every older McLean property has a buried tank. It means the population of houses where the question is worth asking, built before natural gas was standard, sits in specific, nameable neighborhoods rather than being spread evenly across town.
Virginia is a buyer-beware state. The disclosure form's default position, spelled out under the Virginia Residential Property Disclosure Act, is that the owner makes no representations about most conditions and the purchaser is expected to inspect for themselves. Where the state wants sellers to flag something specific, it writes a line item: wastewater systems, solar panels, dam break zones, flood hazard areas, defective drywall, lead pipes. An underground oil tank isn't one of them.
The instinct is to read that absence as reassurance, as if the state decided this particular risk doesn't rise to the level of the others. That's the wrong read. The form's list is narrow by design, and everything outside it still falls under the general buyer-beware framework, which protects a seller only for what they genuinely don't know. If a seller is aware a tank exists or once existed and says nothing when a buyer asks, or lets a home inspection proceed without mentioning it, that silence can expose them to a fraud claim after closing under the same code section that governs the rest of the disclosure act. The form doesn't ask the question. That doesn't mean the answer stops mattering the moment a contract is signed.
Sellers who assume the absence of a checkbox means the absence of a problem tend to find out otherwise from their buyer's lender or insurer, not from the state. Mortgage lenders increasingly require a tank sweep and, if one turns up, removal before they'll finance a purchase, and some are now applying the same condition to refinances on properties they already hold. Homeowners insurance carriers have followed the same path, in some cases declining to renew coverage on a known underground tank until it's addressed. Neither requirement shows up anywhere on the Virginia disclosure form. Both can stall or unwind a deal that was otherwise ready to close.
The practical fix is the same one real estate professionals in Virginia are increasingly trained on: confirm the answer before listing rather than during due diligence. A tank sweep, using ground-penetrating radar and metal detection to check for a buried tank, runs roughly $275 to $450 with a licensed Virginia contractor. Old Dominion Environmental, which lists McLean among the Northern Virginia communities it serves, is one of the firms doing this kind of tank removal and abandonment work locally. Full removal, once a tank is confirmed, typically runs $1,800 to $3,500 depending on size, depth, and how hard the tank is to reach.
The number that scares people is remediation. If soil testing finds contamination from a leak, cleanup can run anywhere from $12,000 to $50,000 depending on how far the oil has migrated. That's the figure that shows up in worst-case headlines, and it's real. It's also not the number most sellers should expect to pay out of pocket.
Virginia has run a Petroleum Storage Tank Fund since 1992 specifically to cover this situation. A homeowner who reports a leak to the Department of Environmental Quality and works through the required process pays a financial responsibility deductible of $500 for a residential heating oil tank, plus a modest inspection and reporting fee that historically has run under $500 more. Beyond that, the fund covers cleanup and third-party liability. The catch is procedural rather than financial: the responsible party is whoever owns the property when the release is discovered and reported, and failing to report a known leak can cost a seller access to the fund entirely. Getting ahead of the question before listing isn't just about avoiding a renegotiation with a buyer. It's what keeps the state's own safety net available if something is found.
For a McLean seller in a pre-1975 property, the sequence that avoids the worst outcomes looks like this. Order a tank sweep before the home goes on the market, not after a buyer's inspector finds a pipe sticking out of the side yard. If a tank turns up, get it into the hands of a licensed Virginia contractor for removal or proper abandonment, with documentation you can hand to a buyer's attorney later. If the property already went through this once, years ago, track down whatever paperwork exists confirming the tank was closed according to code, because "removed at some point" and "removed with documentation" are not the same thing to a lender underwriting the next sale.
None of this requires waiting on Virginia to add a line to its form. The form was never going to be the mechanism that protects a seller here. The mechanism is knowing what's under the yard before someone else finds out for you.
Does selling a home "as is" remove the obligation to mention a known tank? No. Selling as-is shifts responsibility for inspection onto the buyer, but it doesn't erase liability for actively concealing something the seller already knows. If a seller is aware of a tank and stays silent when asked, or takes steps to keep it from being found, that crosses from buyer-beware into the kind of misrepresentation Virginia law addresses separately.
What if I genuinely don't know whether there's a tank on the property? That's the exact situation the buyer-beware framework is built around, and it's different from knowing and staying quiet. A pre-listing sweep replaces uncertainty with an answer, which is generally better for a seller than finding out mid-contract when a buyer's inspector raises it first.
What happens if a tank has already been removed but I don't have the paperwork? Lenders and buyers increasingly want to see documentation of proper closure, not just verbal assurance that it happened years ago. Without records, a soil test or fresh contractor assessment is usually the faster path to closing than trying to track down decades-old permits.
If you're weighing whether a Chesterbrook rambler or a Langley Farms colonial might still be sitting on an old oil tank, that's exactly the kind of detail worth surfacing before a listing goes live rather than after an offer comes in.
