For a 500-gallon propane tank, the general guideline set by the National Fire Protection Association (NFPA) is a strict 10-foot minimum clearance. This distance must be maintained between the tank and:

• Your house
• Your neighbor's property line
• Any ignition sources, such as an air conditioner or generator

Important Considerations:

• Local Codes are the Boss: While the 10-foot rule is a good starting point, local municipalities and fire departments may have their own stricter requirements. Always check with your local fire department or building code office.
• Action Plan: To ensure a safe and compliant installation, you should contact your propane supplier, as they are knowledgeable about local codes, and consult with local authorities to confirm any specific requirements or permits needed.

Propane Tank Access & Supply Line Installation

To ensure safe and efficient propane delivery and installation, it is crucial to provide a clear path for the delivery truck, driver, and the supply line.

• Clear the Driveway: Propane delivery trucks are large (around 10 feet wide and up to 30 feet long). Make sure your driveway is wide enough and free of any obstacles like parked cars, toys, or trash cans.
• Clear the Path to the Tank: The driver needs a clear path to run the hose to your tank. A path of 18 inches to 4 feet wide from the driveway to the tank is recommended. This path should be free of overgrown bushes, branches, and debris.
• Clear Path for the Supply Line: When running the propane supply line from the tank to the house, a clear path is essential. The line, which is often buried, must be free of obstructions that could damage it or impede installation. The path of the supply line should:
• Avoid permanent structures like buildings, sheds, and swimming pools.
• Avoid areas around large trees where roots might need to be damaged during trenching.

Avoid underground utilities, such as water, sewer, electrical, or telephone lines. Damaging an existing utility line can be dangerous and costly. Always contact your local utility companies or "811" (in the United States) before you dig to have all underground utilities marked.
