A new propane installation in Southwest Ohio may require local approval before work begins, and the permit process varies by municipality. The best first step is to confirm the rules with the authority having jurisdiction, then choose a tank size and location that satisfy propane code, property conditions and inspection requirements.
Why Propane Permitting Is Local
Propane systems in Ohio are governed by the Ohio Fire Code and NFPA 58, the Liquefied Petroleum Gas Code. Ohio’s current LP-gas rule modifies the 2021 International Fire Code and sets state permit triggers for certain installations, including stationary containers over 2,000 gallons of individual water capacity. However, a city, county building department or fire official may administer additional permits and inspections for work within its jurisdiction.
That local layer matters across Collett Propane’s 13-county Southwest Ohio service area. For example, Greene County’s 2026 fee schedule lists a $150 propane tank permit, while the county explains that its Building Regulation Department does not cover every municipality within the county. Always verify requirements for the exact project address instead of relying on a rule from a neighboring township or city.
Start With the Authority Having Jurisdiction
Before excavation, tank delivery or gas-line work, identify the department responsible for the property. Depending on the address and project, that may be a county or municipal building department, fire department or zoning office.
Ask these questions:
- Is a permit required for the tank, gas piping, appliances or generator?
- Who must submit the application: the property owner, propane supplier or another contractor?
- Does the application require a site plan, equipment specifications or contractor information?
- Which inspections are required, and must they occur before the tank is filled or the system is placed in service?
- Are zoning, well, septic or utility approvals also needed?
Confirming these details early can prevent a rejected tank location, rescheduled installation or added excavation.
Plan Tank Placement Before Applying
Tank capacity and whether the tank is above ground or underground affect the available placement options. As practical planning guidelines, our team commonly screens proposed sites using these clearances:
- 100- to 125-gallon tanks: These may be placed beside a building in qualifying installations, with no more than two tanks together.
- 250- to 500-gallon tanks: Plan for at least 10 feet from an important building and a property line that can be built upon, whether the tank is above or below ground.
- 1,000-gallon tanks: Plan for 25 feet from buildings and buildable property lines when above ground, or 10 feet when underground.
These are starting points, not a substitute for a site review. The Ohio Fire Code’s container-location table varies separation distances by capacity and installation type, and it includes specific conditions and exceptions. The local official has the final say on what is acceptable for a particular property.
Check Openings and Ignition Sources
A compliant site is more than a measurement from the tank shell. Regulators, relief valves, filling connections and vents may each have clearance requirements from:
- Electrical outlets and equipment
- Air-conditioning units and other ignition sources
- Windows, crawl-space vents and other building openings
- Direct-vent appliance openings and mechanical air intakes
As a general planning rule, keep a propane regulator at least 5 feet from electrical outlets or appliances and at least 3 feet from a lower window or opening. The NFPA’s container-placement guidance illustrates why the exact component and nearby feature matter: its example uses different minimum clearances for relief-valve discharge, fill connections, ignition sources and building openings.
Propane also behaves differently from natural gas. Federal pipeline safety guidance explains that propane vapor is heavier than air and can move along the ground or collect in low areas, while natural gas is lighter than air and tends to rise. That is why basement windows, crawl spaces and low openings deserve careful attention.
Account for Wells, Septic Systems and Delivery Access
We also plan for at least 10 feet between a propane tank and a well and 25 feet between the tank and a septic system. The final layout should protect buried utilities and leave practical access for installation and future deliveries.
Show the following on a simple site sketch:
- Property lines and nearby buildings
- Proposed tank and regulator locations
- Windows, vents, outlets, HVAC equipment and generators
- Well and septic locations
- Driveway access and the proposed gas-line route
What to Expect After Approval
Once the responsible authority and permit requirements are confirmed, the installation can be coordinated around any required inspections. Do not cover trenches, backfill an underground tank or place the system in service until the installer and inspector say it is appropriate. Keep permit records and approved plans available in case the inspector requests them.
Requirements can change, and unusual site conditions may call for a different layout. A qualified propane professional can coordinate tank sizing and placement with the applicable local authority before work starts.
