For about two decades, selling a house on Staten Island came with a quiet workaround. New York state law let a seller skip the Property Condition Disclosure Statement entirely and instead hand the buyer a flat $500 credit at closing. Pay the $500 once, and you never had to answer a single question about the roof, the basement, or what was buried in the backyard. Nearly every transaction in the borough used it. Buyer attorneys expected it. Title companies barely glanced at the form when it did show up.
That option ended on September 22, 2024, when New York amended Real Property Law §462. The $500 credit is gone. In its place is a mandatory 48-question disclosure form covering roof condition, basement flooding, structural defects, and environmental hazards, on virtually every one-to-four-family residential sale in the state. The seller signs it under personal liability for anything materially false, and it stays in the closing file for six years, the length of New York's fraud statute of limitations.
Two years in, plenty of Staten Island homeowners preparing to list still think about disclosure the old way. That gap matters most on one specific question: the oil tank.
Why the Oil Tank Question Is the One That Trips People Up
Staten Island has a lot of housing stock from 1940 to 1975, the decades when oil heat delivered from a buried tank was the standard setup across the borough. Many of those homes converted to natural gas sometime in the 1980s, 90s, or 2000s. When that happened, the old underground tank usually went one of two ways.
Some were properly decommissioned. The tank was emptied, cleaned, filled with sand, and the paperwork was filed with the correct agency. That tank is a non-issue on today's disclosure form.
Others were simply abandoned in place. The fill pipe got capped, the vent pipe stayed sticking out of the ground or got buried too, and everyone moved on. No paperwork exists because none was ever filed. That tank is not a heating footnote anymore. It is a six-figure environmental liability if it has leaked, and it now sits directly inside the scope of a disclosure form the seller is signing under personal liability.
The problem for a lot of current owners is that they simply do not know which version happened. The conversion may have been done by a prior owner, or by a contractor decades ago whose invoice was never kept. "I don't know" feels true. Whether it protects you on the form depends on what you did before writing it down.
"Unknown" Is Not a Blanket Answer
The disclosure form allows "unknown" as a legitimate response to plenty of its 48 questions. Nobody expects a seller to know the exact age of electrical service installed in 1962. But using "unknown" as a default answer across the whole form, without having made any effort to check, reads very differently to a buyer's attorney than an honest "unknown" backed by a documented attempt to find out.
That distinction is exactly where the oil tank question sits. A seller who says "unknown" and has never looked is inviting the buyer's inspector to find the fill pipe during attorney review, at which point the discovery becomes negotiation leverage on someone else's timeline. A seller who says "unknown, but here is the ground-penetrating radar sweep we had done before listing and here is what it showed" has turned the same fact into a controlled, documented answer instead of a surprise.
The $400 Question That Avoids the $40,000 Problem
A pre-listing tank sweep, using a metal detector or ground-penetrating radar to check for a buried tank, typically runs around $400. That is the cost of finding out on your own schedule.
Compare that to what happens on the other two paths. If a tank turns up and needs to be removed with no contamination present, standard removal runs $1,500 to $3,000, covering permits, excavation, and proper disposal. If the tank has actually leaked, cleanup costs climb into a different category entirely, often quoted in the $20,000 to $50,000 range depending on how far the contamination has traveled into surrounding soil.
The gap between those numbers is the whole argument for checking before you list rather than waiting for a buyer's inspector to check for you. A seller who finds a leak-free tank before listing controls the contractor, the price, and the timeline. A seller who finds out during attorney review is negotiating from behind, often against a buyer who has already priced in some padding on top of the actual removal cost.
Most conventional lenders will not finance a home with a known, undocumented underground tank, which means an unresolved tank rarely stays a paperwork issue. It becomes a financing issue for whoever buys the house, and that pressure eventually lands back on the seller's side of the table.
The Same Conversation Now Includes the Basement and the Flood History
The oil tank is the sharpest example, but the new disclosure form widened the conversation in two other directions that matter specifically on Staten Island.
The first is the basement. Mother-daughter layouts and finished basement apartments are common across the borough, but a lot of those units were never brought up to a legal second-unit standard. The house still carries a single-family certificate of occupancy even though it functions as two. That mismatch used to be something a $500 credit could paper over. It is now a direct disclosure question, and getting it wrong creates the same six-year exposure as an undisclosed tank.
The second is flooding. New York's 2024 flood disclosure law requires sellers to disclose prior flooding to the home, garage, basement, or any other structure, regardless of whether the damage was repaired or the home has since been elevated. On the East Shore, in neighborhoods like New Dorp, Midland Beach, and Oakwood, that history often exists in insurance claim records, FEMA disaster declarations, and NY Rising files from Hurricane Sandy or Ida, whether or not the current owner thinks of it as relevant anymore. Marking "no" on a property that shows a claim in those records is one of the more common sources of post-closing disclosure disputes in the borough right now.
None of this means a seller in New Dorp or Oakwood has a worse house to sell than one in Tottenville or Great Kills. It means the paperwork has to match the actual history, not the seller's memory of how long ago the repair happened.
What This Means If You're Listing This Fall
The practical shift is smaller than it sounds but easy to miss if you have not sold a house on Staten Island since before 2024. The disclosure form is no longer something to handle in five minutes at the kitchen table the week before closing. It works better as part of prelisting prep, alongside the things sellers already expect to do: pulling old contractor invoices, checking the original closing folder from when you bought the home, and confirming with your inspector or contractor whether any oil tank question has an actual answer behind it rather than a guess.
That kind of preparation does not add much time to a listing timeline. A tank sweep and a records check can happen in the same window as getting a house photo-ready. What it changes is which side of the negotiation you are standing on when the question eventually comes up, because on a form with six years of exposure, it always comes up.

A Few Questions Worth Asking Before You List
Do I have to remove an oil tank before I can sell? New York does not require removal by law. In practice, most lenders will not approve financing on a home with a known, undocumented underground tank, so an unresolved tank usually has to be dealt with before or at closing anyway, even without a statute forcing the issue.
What if I genuinely don't know whether my house ever had an oil tank? A $400 sweep before listing settles the question one way or the other. It is far cheaper to find out on a Tuesday afternoon before your house is under contract than to have a buyer's inspector find it during a ten-day attorney review window.
Does the new disclosure law apply to condos or co-ops? The 48-question mandate covers one-to-four-family residential sales. Condo and co-op transactions follow different rules, so a seller moving between property types on Staten Island should not assume the same form applies across the board.
