What is the closest distance in feet a 250 gallon fuel oil tank can be from a property line?

• A. 3
• B. 5
• C. 10
• D. 15

Answer: (B)

The safety rule here is about setback distance for aboveground fuel oil tanks from property lines to reduce the chance that a fire or spill affects neighboring property and to leave space around the tank for maintenance and access. For a 250‑gallon residential heating oil tank, the minimum distance from a property line is five feet. This distance is what many codes, including NFPA 31 and local implementations, require. Distances like three feet are not typically permitted from a property line, while ten or fifteen feet would exceed the standard minimum unless a local code or higher fire hazard demands it. Always check the local authority having jurisdiction, since exact requirements can vary by location.
