A working propane appliance does not prove a permanent pipeline right
If a propane tank or customer-owned line serving the home sits on or crosses neighboring land, verify ownership, route, easement, supplier approval, code compliance, and maintenance access before closing. The tank may be leased while the buried line belongs to a customer, or several buildings may share equipment under an informal family arrangement. Continued deliveries do not establish that the buyer has an insurable right to enter, repair, replace, or keep the line in place.
Propane is flammable. Do not probe for the pipe, operate unknown valves, move a tank, or test for leaks with a flame. If you smell gas, hear hissing, see damaged equipment, or suspect a leak, leave the area, avoid switches and ignition sources, and contact emergency services and the propane supplier from a safe place. Excavation requires utility locating, property permission, and qualified planning; private lines may need separate locating beyond 811.
Illustrative scenario: the tank stayed with the original farmhouse
Imagine a divided farm where the propane tank remains beside the original farmhouse but a buried branch feeds the sold cottage. The seller pays the cottage's fuel share informally, no separate meter exists, and the title commitment lists no propane easement. The supplier's account is in the neighbor's name. The buyer does not assume that changing the billing name will create land rights or supplier approval.
A survey and private locate map the crossing, counsel confirms no recorded right, and the supplier refuses to continue the shared layout after transfer. A licensed propane contractor designs a code-compliant tank and line on the purchased parcel, including setbacks, regulator, protection, permits, leak testing, and abandonment of the old branch. Closing depends on completed service and records rather than a promise to negotiate with the neighbor later.
Identify every component, owner, and user
Collect tank lease or ownership proof, supplier records, serial numbers, bills, permits, inspection and leak-test records, appliance list, line drawings, surveys, easements, shared-use agreements, and seller disclosures. Ask the supplier in writing who owns the tank, regulators, meters, and piping; which structures are authorized; and what changes are required at transfer. Do not infer ownership from who fills the tank or whose name appears on one invoice.
Map the tank, fill connection, regulators, shutoffs, visible risers, likely buried route, buildings, ignition sources, driveways, wells, septic components, property lines, and access. A qualified propane professional should locate and inspect the system using safe methods. Determine whether the neighbor also depends on the tank or line and how fuel is measured. Shared consumption without accurate allocation, maintenance duties, or emergency authority creates operational and closing risk.
Read the easement and supplier rules
Obtain the complete recorded easement, license, lease, or shared-fuel agreement and its survey exhibit. Confirm beneficiaries, burdened parcel, route, width, installation and access rights, emergency entry, notice, vegetation, excavation, restoration, relocation, costs, duration, transfer, insurance, and abandonment. A general utility exception may not cover a privately owned propane service. Local title counsel and the title insurer should address the specific instrument.
Ask the fire marshal or building authority which permits, setbacks, burial, corrosion protection, regulator locations, barriers, pressure tests, and inspections apply. Supplier standards may exceed minimum code and can govern leased equipment. A neighbor's permission cannot waive safety rules. If continued use requires a new easement, obtain all owner and lender signatures and record it before closing rather than relying on an unrecorded letter.
Compare continued service with relocation
Keeping the route may be feasible when the supplier approves it, the system passes inspection and testing, and a surveyed recorded easement gives durable access. The agreement should cover delivery trucks, gates, snow, crops, livestock, damage, leak response, fuel allocation, maintenance, and successors. Consider what happens if the neighboring parcel develops, changes grade, installs a building, or withdraws from shared service.
A relocation estimate should include tank purchase or lease, site preparation, setbacks, barriers, trenching, road crossings, new line, regulators, appliance reconnection, permits, testing, outage, fuel transfer, old-line purge and abandonment, restoration, and easement release. Do not invent a national cost. Obtain supplier and contractor scopes tied to a surveyed site. The lender and insurer should review the final configuration before closing.
Use a closing checklist that survives an emergency
Require a current leak and pressure test where applicable, documented supplier acceptance, clear tank and line ownership, recorded land rights, permits, appliance and regulator inventory, emergency shutoff instructions, delivery access, and lender and insurer approval. The contract should assign investigation and correction costs and permit termination if the supplier rejects continued service or the neighbor will not grant acceptable rights.
If the arrangement remains shared, define who may shut off service during a leak, who calls the supplier, how occupants are notified, and how urgent repair access works when an owner is absent. Store these instructions outside the hazard area with the survey and supplier contact. A financially convenient shared line is not workable if nobody has clear authority to act safely during an outage or suspected leak.
Frequently asked questions
Does an 811 mark prove ownership or rights? No. Can the seller transfer a leased tank? Only under the supplier's agreement. Does long use create an easement? State law is fact-specific; ask counsel. May one tank serve two parcels? It depends on supplier approval, code, metering, agreements, and local rules. Can I test a suspected leak myself? Follow emergency guidance and use qualified professionals.
Who should help? The propane supplier, licensed propane contractor, fire or building authority, surveyor, locator, title counsel, title insurer, lender, insurer, and neighbor. What protects closing? Written supplier acceptance, permits and test records, mapped equipment, clear ownership, a recorded easement or completed relocation, and defined emergency and maintenance duties. Pause when the only heat source depends on revocable permission or undocumented shared fuel.
