New York Oil Tank Rules For Homeowners
The rules that apply to a house tank, with the citations, and the ones that do not.
What matters before the work starts.
A great deal of what is written about New York oil tank law describes rules for commercial facilities and then implies they bind homeowners. This page separates the two.
Your Tank Is Probably Not A Registrable Facility
A heating oil tank used on the premises, not interconnected to another heating oil tank, holding less than 1,100 gallons, on a property with no other qualifying tank system, is excluded from the definition of a facility. No registration follows.
One caution, because it is where most write-ups go wrong. The same definition pulls in any underground tank over 110 gallons, and it is the heating oil carve out that takes an ordinary house tank back out. The two clauses have to be read together.
6 NYCRR Part 613, section 613-1.3(x)(2)(iv), read with 613-1.3(x)(1)(ii).
The Reporting Duty That Does Reach You
Holding legal title to a tank system is enough to make the spill reporting provisions apply, even though your tank is not a registrable facility. A release must be reported to the New York State Spill Hotline on 1-800-457-7362 within two hours of discovery.
The exemption is narrow: under five gallons, contained and under control, not reaching land or water of the State, and cleaned up within two hours.
6 NYCRR 613-1.2(c) with 613-1.3(bu); reporting at 613-2.4(e).
You Do Not Owe The State Thirty Days Notice
The thirty day notice before permanent closure applies to owners of registered facilities. It does not apply to an excluded residential heating oil tank, and being told otherwise is a sign the advice was written for commercial sites.
What does apply to your closure is the technical standard and, in Suffolk County, the county's own permission requirement for filling a tank in place.
6 NYCRR 613-1.9(7).
The Building Code Section Almost Everyone Cites Wrongly
The heating oil tank abandonment provision in the residential code is widely cited as AJ102.8. That citation is to a repealed edition. New York adopted the 2025 Uniform Code with effect from December 31, 2025, and the provision now sits in Appendix BO of the 2025 Residential Code as BO102.11.
The Islip Building Division's own notice confirms the December 31, 2025 changeover. If a contractor quotes you AJ102.8 as current law, they are working from a superseded book.
New York Department of State adoption of the 2025 Uniform Code, effective December 31, 2025. The full item text of BO102.11 should be read in the 2025 appendix rather than taken from the repealed AJ102.8 wording.
The Suffolk County Layer On Top
A residential heating oil tank under 1,100 gallons is exempt from most of Suffolk County's Article 12, including its permit and closure provisions. It stays bound by the prohibition on discharges, by the Commissioner's power to order testing or removal, and by the leaking tank rule.
So the common claim that Suffolk County requires a permit to remove your house tank does not follow from the code. What Suffolk does control tightly is abandonment in place, for tanks that are not exempt.

Questions On This
- Can you sell a house with an underground oil tank in New York?
Yes, there is no state prohibition on selling with a tank in the ground. What has changed is that the Property Condition Disclosure Statement is now effectively mandatory, and Question 21 puts the tank in writing in the file.
- Does New York license oil tank removal contractors?
We could not identify any statewide New York license or certification for tank removal contractors, and we are not going to describe one that we could not confirm exists. The verifiable credentials are the county home improvement license and the state waste transporter permit.
- How long does a tank have to be out of use before it counts as abandoned?
Under Suffolk County's code an abandoned storage facility means one that has been out of service for two years or more, or that the owner has declared abandoned. Out of service includes being substantially empty, meaning five percent or less filled.
