Buying an Older NJ Home: An Oil Tank Checklist

If the house you want was built decades ago, the question of an oil tank is worth asking early. Here is a checklist that fits into a normal New Jersey purchase.

Before you make an offer

• Ask about heating history. Was the house ever heated with oil? When was it converted?
• Ask about the tank. Is there a tank? Was it removed or left in place? Is there paperwork?
• Look for clues. Vent or fill pipes outside, old oil lines in the basement. See clues that a property may have a buried oil tank.

During the attorney review and inspection period

• Read the seller’s disclosure. The state’s instruction sheet says sellers must disclose known material defects even if the form does not ask. Do not treat it as a substitute for your own checks.
• Order a sweep early. Waiting leaves little time to deal with a signal. A sweep tells you whether a tank is likely.
• Plan for follow up. If the result is unclear, an exploratory dig confirms what an object is.
• Ask about records. The NJDEP’s DataMiner lets you search by address for tank cases and NFA letters. See How to Find Out If Your NJ Home Has an NFA Letter.

If a tank turns up

• Ask your attorney how to handle it in the contract. Options include removal before closing, a price adjustment, or walking away.
• Have removal done by a closure-certified firm. See Who Can Remove an Underground Oil Tank in NJ?.
• If there are signs of a leak, the state must be notified right away. See When to Call the NJ DEP Hotline.

After closing

Keep every document: sweep report, dig photos, removal contract, soil results, permits and any No Further Action letter. When you sell, a buyer will want them.

Do you need an oil tank sweep on every house?

Not every home needs one. A newer home that never had oil heat probably does not. For older homes with a heating history you cannot confirm, a sweep is a modest step compared with the unknowns.
