Setback Restrictions From Buildings

OSHA has defined minimum distances between a propane tank and a building or dwelling. Any tank that holds up to 500 gallons must be at least 10 feet away from a building. A tank that holds 501 gallons to 2,000 gallons must be 25 feet away. A tank that holds 2,001 gallons to 30,000 gallons must be 50 feet away if buried underground and 75 feet away if above ground.

Bear in mind that these are OSHA mandates. Local communities may set ordinances that are stricter, such as a 500-gallon tank being required to be 100 feet away from a building. Check with your local building department before setting a tank.

Property Line Restrictions

Most, if not all, communities have property line setback restrictions for propane tanks. These stipulate the minimum distance between a tank and a property line. According to the National Fire Protection Association, tanks with a capacity of 501 gallons to 2,000 gallons cannot be placed closer than 25 feet to a property line. Again, local building department ordinances may have stricter guidelines. Check with local authorities on the setback restrictions.

Space Between Tanks

OSHA has specified the space between tanks, if multiple tank setups are used. The space between two or more tanks holding between 251 gallons and 2,000 gallons can be no less than 3 feet. The space between tanks of 2,001 gallons to 30,000 gallons can be no less than 5 feet. Again, local ordinances may supersede these minimum requirements.


OSHA does not allow stacking of tanks. This is a strong mandate, with no exceptions. If larger capacities of propane are needed, then the smaller tank must be removed and a larger single tank installed.
