If a neighbor’s gas line runs across your property, your rights come down to a single question: is there a legal easement authorizing it? If an easement exists, the line is there lawfully and you can’t force its removal, though your neighbor’s rights are limited to what the easement actually permits. If no easement exists, the line is an encroachment, and you can demand it be moved or negotiate a recorded easement in exchange for compensation. Before you investigate anything on the ground, take one safety step first.
Call 811 Before You Dig or Probe
Call 811 before you hire a surveyor, drive stakes, or break ground anywhere near the suspected line. This is the national “Call Before You Dig” number, and federal law requires every state to maintain a one-call notification system so underground utilities get marked before excavation.1Office of the Law Revision Counsel. 49 U.S. Code 60114 – One-Call Notification Systems Local operators will mark the approximate location of buried gas, electric, water, and other lines at no charge. Most states require at least two full business days of advance notice.
If you ever smell rotten eggs or sulfur near the line, leave the area immediately. Don’t flip switches, start a car, or use a phone until you’re a safe distance away. Call 911 first, then the gas utility’s emergency number.
Find Out If an Easement Exists
An easement is a legal right to use a defined strip of someone else’s land for a specific purpose. It doesn’t transfer ownership, but it does limit what the landowner can do with that strip. Whether one covers the gas line is the hinge of everything that follows.
Check Your Deed and Title Records
Start with your property deed and title report. Recorded easements appear in these documents and run with the land from owner to owner. If you kept your closing paperwork, look at the title commitment and the title insurance policy. If you didn’t, the county recorder’s office keeps the records, and a title company can run a search for a few hundred dollars.
Read the language carefully. Some easements are granted to a specific utility; others benefit a neighboring property. The easement should describe both the location and the permitted use. If the gas line sits outside the described corridor, it can still be an encroachment even though a valid easement exists somewhere else on your lot.
Prescriptive Easements
A neighbor or utility can sometimes claim an easement without any recorded document, based on long, uninterrupted use. A prescriptive easement requires that the use was open, adverse to the owner’s rights, and continuous for a period set by state law.2Legal Information Institute. Prescriptive Easement That period varies by state, commonly running between five and twenty years.
There’s a practical wrinkle with buried gas lines. The use has to be “open and notorious,” meaning a reasonable owner would have noticed it. An underground pipe with no surface markers and no record of installation is hard to call “open.” If visible meters, markers, or above-ground equipment were present throughout the period, the argument is stronger. It’s a fact-heavy question and usually one for an attorney.
Get a Property Survey
A licensed land surveyor can map exactly where the gas line sits relative to your boundaries. The 811 markings give you a rough path; the survey gives you a legally defensible measurement. “I think the line is on my side” doesn’t support any legal action. Cost depends on lot size, terrain, and whether old survey monuments are still in place.
What Your Rights Look Like If an Easement Exists
With a valid easement, the gas line has a legal right to be on your land, and you cannot demand removal. The easement holder can enter the easement area to maintain, repair, and replace the line. You still own the ground, but your use of that strip is restricted. Pouring a concrete pad, building a shed, or planting large trees over it can interfere with access and expose you to liability if something goes wrong during a repair.
Easements aren’t blank checks, though. The holder can only use your property for the purpose the easement describes. A gas easement doesn’t let them run a water line through the same corridor. If the holder’s use exceeds the scope of the easement or causes damage beyond what’s reasonably necessary, you can enforce the easement’s terms in court.
You keep the right to use the easement area in ways that don’t interfere with its purpose. Walking across it, mowing, and light landscaping are generally fine. Just don’t block access or make future maintenance harder.
What Your Rights Look Like If There’s No Easement
If your title search and survey show no recorded easement and no plausible prescriptive claim, the line is an unauthorized encroachment.3Legal Information Institute. Encroachment Whoever owns the line placed it on your property without legal authority, and the burden to fix the situation is theirs.
Don’t wait. The longer an encroachment sits, the harder it can be to resolve: the other side may try to assert a prescriptive easement, and judges sometimes weigh whether you knew about an encroachment and sat on your rights. Once you’ve confirmed the line has no legal basis, start acting on it.
How to Resolve It
Talk to Your Neighbor First
Start with a conversation rather than a lawyer’s letter. Many of these situations trace back to a previous owner on one side or the other, and your current neighbor may not know the line crosses the boundary. Bring the survey and the title findings so the discussion rests on facts. A cooperative neighbor makes everything that follows faster and cheaper.
Contact the Utility Company
Call the gas utility that serves the area. They can tell you whether they own the line, whether it’s a private line belonging to your neighbor, and whether they hold a recorded easement. The distinction matters. A utility-owned line is the utility’s responsibility to maintain and, if it has to move, their problem to solve. A private line running from a main to your neighbor’s home is typically your neighbor’s property and responsibility.
Negotiate a Recorded Easement
Removal isn’t always the practical answer. Rerouting a gas line is expensive, disruptive, and requires permits and licensed contractors. If the line doesn’t interfere with any planned use of your property, granting a formal easement in exchange for compensation can be the sensible outcome. Common remedies for an encroachment include negotiation, sale of the affected land, or granting an easement.3Legal Information Institute. Encroachment
A negotiated easement should be drafted by an attorney and recorded with the county so it runs with the land. Key terms include the exact boundaries, who maintains and repairs the line, who carries liability insurance, and what happens if the line later needs replacement. Compensation typically starts from what the strip would be worth as unrestricted land, with a premium for the ongoing limitation.
Send a Demand Letter
If the neighbor won’t engage, a demand letter from an attorney formalizes the dispute. It should reference the survey, the absence of an easement, and a specific deadline for removal or resolution. Beyond the pressure it applies, the letter builds a written record showing you acted promptly and in good faith, which can matter later in court.
Mediation
Mediation puts both sides in front of a neutral third party who helps negotiate a resolution without a judge. It’s faster and far cheaper than litigation, and because it’s collaborative, it tends to preserve the neighbor relationship. Many courts require mediation in property disputes before setting a trial date, so you may end up there regardless.
Lawsuit
If nothing else works, the typical claims are trespass (an ongoing physical intrusion on your land) and a request for injunctive relief, a court order compelling the line’s removal. Injunctive relief is the standard remedy when an owner wants an encroachment physically removed.3Legal Information Institute. Encroachment Monetary damages for loss of use or diminished property value may also be available. Be realistic: property litigation often runs a year or more, and legal fees in a contested case can reach five figures.
Who Pays to Move the Line
If there’s no easement and the line has to be moved, the encroaching party pays. They placed the line on your property without authorization, and the cost of correction is theirs. Enforcing that principle sometimes takes a court order, especially if the neighbor disputes your findings.
Relocating a residential gas line typically runs about $15 to $25 per linear foot for materials and labor, with most straightforward projects falling between roughly $375 and $1,000. Excavation, permits, and restoring landscaping push the total higher, and a line running under hardscape like a driveway climbs quickly. Only a licensed plumber or gas utility contractor should do the work. This is not a DIY project.
If you grant a formal easement instead, there’s no relocation bill, but you should negotiate compensation that reflects both the land value and the ongoing restriction. An attorney familiar with your area can advise on what’s reasonable.
Selling Your Home With the Issue Unresolved
An unresolved gas line encroachment complicates a sale and can’t be ignored. Nearly every state requires sellers to disclose known material defects and legal issues affecting the property, and an unresolved encroachment falls into that category. Failing to disclose exposes you to fraud claims and civil liability after closing.
Title insurance is the other pressure point. Standard policies generally exclude matters not recorded in public records, so an unrecorded encroachment won’t appear in a title search, but it can still surface in the buyer’s own survey or inspection. Lenders are cautious about anything that could impair their collateral, and even the mere assertion of an unrecorded easement can create a cloud on title that must be cleared before closing.
The cleanest approach is to resolve the problem before listing. Whether that means removal, a recorded easement, or a written agreement with the neighbor, a clean resolution takes the issue off the table. If you sell with it still in place, expect buyers to negotiate a lower price or walk away.
Safety and Liability While the Line Is Still There
Whichever path you’re on, someone’s gas line is on your property right now, and the owner of the line is responsible for keeping it in safe working condition. If the utility owns it, maintenance is theirs. If it’s a private line belonging to your neighbor, the responsibility is your neighbor’s.
Your obligations as the landowner are to avoid damaging the line and to report trouble. If you smell gas, see dead vegetation in a line pattern, or hear hissing near the ground, treat it as an emergency: leave the area, avoid sparks and flames, and call 911 followed by the utility’s emergency line. Don’t try to locate or expose the line yourself.
If the line leaks and damages your property, the line’s owner is generally liable for the resulting harm. Your homeowners insurance may cover some damage from an explosion or fire, but standard policies typically don’t cover damage to buried utility lines themselves. Keep your survey and title search results in writing. They establish who owns what and who answers for it if something goes wrong.
