How close you can build to a utility easement depends on where the easement sits on your property and what your local code requires: in most cases you can build right up to the easement’s outer edge, but you cannot place a permanent structure inside it without written permission from the utility, and some jurisdictions add their own setback on top. The practical work is figuring out exactly where that edge is.
Find the Easement’s Exact Location First
You cannot answer “how close” without knowing where the easement boundary actually runs. Several documents and services get you there, and using more than one is smart because each has gaps.
- Your property deed contains the legal description and should reference any recorded easements, including dimensions. If you don’t have a copy, the county recorder’s office does.
- The title report from when you bought the property lists easements and other encumbrances. If you have an owner’s title insurance policy, the report came with it.
- The plat map, available from the county recorder or clerk, is a scaled drawing showing lot boundaries and easement locations with precise dimensions. For subdivision properties, it’s often the most useful visual reference.
- Calling 811 sends utility locators to mark underground lines with paint or flags, free of charge, typically within a few business days. This tells you where lines physically sit, which may not match the recorded easement exactly.
- Contacting the utility directly can reveal both where lines run and the company’s internal encroachment policies. Some utilities maintain GIS maps more accurate than decades-old plats.
When to Hire a Land Surveyor
If you’re building close to an easement edge, a licensed land surveyor is the most reliable answer. Surveyors use GPS equipment and total stations to establish reference points, then physically stake the easement boundaries so you can see where the restricted zone starts and ends. A residential boundary survey that includes easement location typically runs between $1,200 and $5,500, depending on property size, terrain, and the complexity of the legal description. That’s a fraction of what it costs to demolish a garage that turns out to sit three feet inside an easement.
A survey matters most when your deed or plat map is old, when the property has changed hands many times, or when you’re building near the edge. If your planned structure sits 30 feet from what you think is a 20-foot easement, eyeballing is probably fine. If you’re trying to squeeze a detached garage two feet outside the boundary, spend the money.
How Wide Utility Easements Usually Are
Widths vary by utility type and infrastructure size. Overhead electric distribution lines along residential streets commonly carry easements around 30 feet wide. Higher-voltage transmission lines often require 50 feet or more. Underground electric lines tend to be narrower, typically 10 to 20 feet. Water and sewer easements usually run about 20 feet, sometimes 30 feet or wider for larger mains buried deeper.
These widths aren’t arbitrary. They account for the space utility crews need to bring in excavation equipment, stage repairs, and work safely without spilling onto property outside the easement. A 20-foot sewer easement doesn’t mean the pipe is 20 feet across; it means the utility needs that much room to dig down, shore up trench walls, and operate machinery.
What You Cannot Build Inside an Easement
Permanent structures with foundations are the clearest prohibition. Home additions, detached garages, in-ground pools, concrete patios, and retaining walls all fall in this category. These structures physically block the access the easement exists to protect. If a utility crew needs to excavate a water main running under your garage slab, the slab goes, and the utility isn’t paying to replace it.
Heavy structures also risk damaging the infrastructure itself. Building weight can shift soil around buried pipes, and deep foundations can contact or compress utility lines. For overhead easements, the concern flips vertical: anything tall enough to encroach on the clearance zone around power lines creates a safety hazard, and minimum clearances increase with voltage.
What You Might Be Allowed to Build
Less permanent improvements sometimes get approved, though “less permanent” does more work in that phrase than most homeowners expect. Sheds without concrete foundations, certain fences, removable decks, and landscaping are the usual candidates. Every one of them still requires the utility company’s written permission before you start.
Fences are the most common request and show how conditional approval works in practice. A utility may allow a fence across its easement only if it includes a gate wide enough for service vehicles, uses materials that can be removed quickly, and stays below a set height. Some sewer districts prohibit fences within their easements entirely. Install one without checking and you may get a letter demanding removal at your expense.
Landscaping seems harmless but has its own rules. For underground easements, the worry is root systems: trees with deep or aggressive roots planted over a buried water line can crack the pipe over years. For overhead easements, the worry is height, and species that grow tall enough to contact power lines are generally prohibited, with the utility retaining the right to trim or remove them. Shallow-rooted ground cover, flower beds, and low shrubs are the safest choices within any easement.
One boundary worth flagging: if your property sits near a natural gas or hazardous liquid pipeline, federal rules add restrictions beyond the easement itself. For hazardous liquid pipelines, federal regulations prohibit pipeline placement within 50 feet of any private dwelling, industrial building, or place of public assembly, and building a new structure within that zone can create a compliance problem for the operator.1eCFR. 49 CFR 195.210 – Pipeline Location Natural gas transmission pipelines carry their own class-location framework that can trigger costly pipe upgrades when nearby construction increases building density, giving the operator strong reason to object.2eCFR. 49 CFR 192.5 – Class Locations
Local Setback Rules Can Push the Line Further Out
Utility approval doesn’t excuse you from the building permit process, and the permit process often catches easement conflicts on its own. When you submit plans, the local building department typically reviews them against recorded easements and may forward them to utility departments for additional review. If your proposed structure encroaches, the permit can be denied until you produce an executed encroachment agreement or change the plans.
Some zoning codes impose their own setbacks from easement boundaries. Where the utility might technically let you build right up to the edge, local code may require an additional buffer of several feet. These rules vary by jurisdiction, so check with your local planning or zoning department before assuming “outside the easement” means “free to build.” Permit review generally takes 60 to 90 days when utility reviews are involved, so plan the timeline accordingly.
Getting an Encroachment Agreement
When your plans overlap with an easement, the formal path is an encroachment agreement, sometimes called a license agreement or consent to encroachment. It’s a written contract between you and the utility that grants revocable permission to place a structure within the easement area under specific conditions.3Dominion Energy.

The application requires detailed documentation. Expect to submit a certified site plan or survey showing property boundaries, the easement’s location, and the proposed structure’s exact placement relative to utility infrastructure. You’ll typically also need construction drawings, a description of materials, and profile views showing clearances from any utility facilities.4CenterPoint Energy.

The utility reviews your application against current and future infrastructure needs. Approval is not guaranteed. Even when approved, the agreement almost always includes two conditions homeowners find uncomfortable: you assume all risk of damage to your structure if the utility needs access, and you agree to remove the structure at your own expense if the utility demands it. “Revocable” is doing real work in these agreements. The utility isn’t giving you permanent rights; it’s tolerating your structure for as long as the structure doesn’t get in the way.
What Happens If You Build Without Permission
Skipping approval is one of those gambles that looks low-risk until it isn’t. The utility holds the legal right to access its easement whenever it needs to, and any unauthorized structure in the way can be removed. If a water main breaks under your unpermitted shed, the crew isn’t going to work around it. They’ll demolish it, fix the pipe, and leave you with the debris.
Financial exposure goes beyond losing the structure. The easement language in your deed almost certainly protects the utility from liability for damage to unauthorized improvements. You won’t be compensated for the structure, the landscaping torn up, or the cost of hauling away wreckage. If the utility spends extra money working around your structure before removing it, you may be billed for those additional costs.3Dominion Energy.

The problems compound at sale. An unauthorized structure on a utility easement surfaces in the buyer’s title search and inspection. Lenders are wary because the structure could be removed at any time, making value unpredictable. A title company may refuse to insure around the encroachment, and a buyer’s lender may refuse to close until the structure is removed or a retroactive encroachment agreement is obtained. Getting that agreement after the fact, with the structure already built, puts you in the worst possible negotiating position with the utility.
When an Easement Can Be Removed
If an easement on your property appears to no longer serve any active infrastructure, you may be able to get it formally terminated. It’s a heavier lift than most homeowners expect but worth exploring when an easement is genuinely obsolete.
The simplest path is a written release from the utility. If the company confirms it no longer needs the easement, both parties sign a termination document that gets recorded with the county to clear the property’s title. This is straightforward when it works, but utilities are often reluctant to release easements even when no active lines exist, because they may want the corridor for future use.
When the utility won’t voluntarily release, you can argue abandonment, but the bar is high. You generally need to show both that the utility has stopped using the easement and that it intended to permanently give up its rights. Simple non-use isn’t enough. Courts treat this as a fact-intensive inquiry, and some states require 20 years of continuous non-use before abandonment becomes a credible argument. An easement can also terminate automatically if the same party comes to own both the easement rights and the underlying property (the merger doctrine), or if the easement was created out of necessity and that necessity no longer exists. Either route typically needs a court order to clear the land records. Before pursuing any of this, read the original easement document; some contain their own termination provisions, such as expiration dates or default clauses, that offer a cleaner path than litigation.
