April 5, 2026

Quick Answer

In the US, requirements for underground propane tank permits vary by state and local jurisdiction, but typically include submitting plans, obtaining a permit, and hiring a licensed installer who follows National Fire Protection Association (NFPA) guidelines. Permits usually require inspections before and after installation.

Underground Propane Tank Permit Requirements

Submission and Inspection Process

To obtain an underground propane tank permit, you’ll need to submit detailed plans to your local authorities, including the tank’s size, material, and installation location. These plans must meet the NFPA’s 58 standards for liquefied petroleum gas (LPG) systems. Once your plans are approved, a local inspector will conduct a pre-installation inspection to ensure compliance with regulations.

Installation by a Licensed Professional

It’s essential to hire a licensed propane installer who has experience with underground tank installations. They will be responsible for complying with local regulations and NFPA guidelines. Make sure to verify their credentials and references before hiring them. A typical underground propane tank installation process involves digging a hole for the tank, connecting it to a pressure regulator, and ensuring proper venting and drainage.

Post-Installation Inspections and Maintenance

After the installation, your local authorities will conduct a post-installation inspection to verify that the tank was installed correctly and safely. You’ll also need to schedule regular maintenance with a licensed propane technician to ensure the tank’s integrity and the safety of your family and property. This maintenance typically includes inspections, tank testing, and replacement of worn-out components.

Additional Requirements

Some states and local jurisdictions may require additional permits or inspections for underground propane tank installations, such as a building permit or a fire department permit. Check with your local authorities to determine the specific requirements in your area. It’s also essential to ensure that your propane tank complies with local regulations regarding setbacks from property lines and buildings.
