Short answer: Many older North Jersey homes once heated with oil and may still have an underground tank. Before buying, get a tank sweep. Before selling, find out whether a tank exists and whether it was properly closed. A leaking tank must be reported to NJDEP and cleaned up by certified professionals, and that can delay or derail a sale.
How residential oil tanks are regulated
NJDEP calls home heating oil tanks “unregulated” tanks, but there are still rules. Closure must be done by a contractor certified by the state, and any cleanup of a leak follows the state’s heating oil tank remediation rules. Your town also requires a permit to remove a tank or abandon it in place, and the fire subcode official inspects the work.
For buyers: always order a tank sweep
A tank sweep uses metal detection or ground-penetrating radar to find buried tanks. It is especially important for homes built before the 1970s that now heat with gas, since an old tank may have been left in the ground. Signs to look for include fill or vent pipes on the outside of the house.
For sellers: get ahead of it
- Gather records. Removal paperwork, soil test results and the town’s certificate of approval are what buyers and their attorneys want to see.
- Sweep the property before listing if you are unsure. Finding a tank early lets you plan instead of renegotiating under pressure.
- Remove or properly close an old tank with a certified contractor and a town permit.
What if the tank has leaked?
Call the NJDEP hotline at 1-877-WARNDEP (927-6337) if there are holes in the tank, stained soil, fuel odor or lab results showing petroleum. The owner must hire a Certified Subsurface Evaluator or a Licensed Site Remediation Professional. Cleanup costs vary widely, and they rise sharply if groundwater is affected. When work is complete, NJDEP issues a No Further Action letter.
Insurance and state funding
Most homeowners policies exclude oil tank pollution, though some insurers offer limited add-on coverage. The state’s Petroleum Underground Storage Tank fund closed to new non-leaking tank applications in 2011, and leaking-tank applicants have faced long review waits, so do not count on it.
Can you still sell?
Yes. Homes with tanks sell every day when the issue is handled transparently. In some cases a cash offer or an as-is sale is the simpler path. Estates often uncover tanks, so see our estate home sales page too.
