What is the minimum distance an above-ground oil tank over 275 gallons can be installed next to a building?

• A. 5 feet
• B. 15 feet
• C. 10 feet
• D. 20 feet

Answer: (C)

The main idea is safety clearances for storing a large amount of fuel near a building. Putting an above-ground oil tank over 275 gallons at a safe distance from the structure helps limit the chance that a fire or heat from the tank will affect the building, and it gives space for maintenance and firefighting if needed. For these larger tanks, a 10-foot setback from the building is typically required by many codes and standards because it provides a reasonable buffer zone without being overly restrictive. Some places may require different distances, but 10 feet is the commonly accepted minimum. A smaller distance like 5 feet would generally not meet code for a tank of this size, while larger setbacks (15 or 20 feet) exceed the minimum in most jurisdictions.
