I Want to Build on My Land but My Neighbor Has an Easement (Missouri)

So the real question is rarely "can I build?" It's "does my planned structure materially impair what the easement actually allows?" A patio over a footpath easement is a very different problem than a garage on top of a buried sewer main. The path forward is to pin down exactly what the easement says, find out whether your build even touches it, and then pick the cleanest option.

Start with the recorded easement itself

Everything turns on the document. Don't rely on memory, a neighbor's say-so, or what the prior owner mentioned at closing. Pull the actual recorded instrument from the county recorder's office (it may be a separate easement agreement or language inside a deed) and read it closely for three things.

• Exact location and width. Many easements describe a defined route and width tied to a survey. Some older ones are vague ("a roadway as now located"). The precise footprint tells you how much of your land is actually burdened — often far less than people assume.
• The purpose. This is the heart of it. An easement for a driveway gives different rights than one for a utility line or a footpath. A holder may use the easement only for the purpose it was granted, so the purpose defines what counts as "interference."
• Whether it's express, implied, or prescriptive. An express easement is written and recorded, so its terms control. An implied or prescriptive easement (gained by ten years of open, continuous, adverse use) is defined by the historical use itself — which makes its scope murkier and worth a lawyer's read.

Get a survey before you draw any plans

A current survey from a licensed Missouri land surveyor does two jobs at once: it locates the easement's true footprint on the ground, and it shows whether your planned structure even touches it.

• Your build may miss the easement entirely. Surveys frequently reveal that the burdened strip is narrower or sits differently than everyone believed. If your garage footprint clears it, much of your worry disappears.
• It shows the degree of any overlap. If you do touch the easement, the survey tells you whether you'd cross a foot of a wide driveway easement or sit squarely on top of it — and that difference often decides whether the use is "reasonable."
• It's your strongest evidence later. A stamped survey is the document that carries weight in a conversation with the holder, in negotiation, or in court.

Photograph and date the staked footprint. That record matters if anyone later disputes what you built and where.

Know what "unreasonable interference" means

You are allowed to use the burdened strip for any purpose that does not unreasonably interfere with the easement holder's reasonable use. That's the legal test, and it's fact-specific.

• Things that usually pass: landscaping, a removable fence with a gate that preserves a driveway's passage, planting, regrading that doesn't block access, or building entirely outside the footprint.
• Things that usually don't: a permanent building, wall, or pool that sits on the route and blocks the very passage or access the easement exists to provide.
• Purpose is everything. A solid fence across a driveway easement defeats its purpose; the same fence across a buried-utility easement might be fine for access but still barred if the easement document forbids permanent structures over the lines.

Be honest with yourself about overburdening in reverse: just as a holder can't expand their use, you can't dress up a structure that genuinely guts their access and call it "reasonable."

Utility easements need a call to the utility

If the easement belongs to a power, water, sewer, gas, or telecom company (an easement in gross), treat it as its own category before you build anything over or near it.

• Contact the utility directly. They typically have written setback and access requirements, and many recorded utility easements flatly bar permanent structures — decks, additions, pools, slabs — over their lines.
• Assume they can dig. Even where a structure is technically allowed, an owner who builds within the strip often has to remove the encroachment at their own expense when the utility needs to reach its lines. A garage you tear out in five years is worse than no garage.
• Get written sign-off. If the utility is willing to let you build, get its approval in writing before you pour a footing.

Your options if the build conflicts

If the survey shows a real conflict, you still have several paths, from simplest to most involved.

• Build outside the footprint. The cleanest fix is often to shift the project a few feet so it clears the easement entirely. No permission needed.
• Negotiate a recorded relocation or modification. You can ask the holder to agree, in writing, to move or shrink the easement to free up your build site. Be honest about the law here: Missouri traditionally requires the holder's consent to relocate an easement — a servient owner generally cannot move it unilaterally, even to a more convenient spot. If they agree, record the amendment so it binds future owners.
• Seek termination if the easement is dead. If the easement has been abandoned (non-use plus clear intent to give it up) or its purpose has ended — for instance, an easement by necessity once the dominant parcel gains another legal outlet — you may be able to have it extinguished. Non-use alone is usually not enough.
• Ask a court to define the scope. When the easement is vague or the parties simply can't agree, a declaratory-judgment or quiet-title action asks a judge to fix the location, width, and permitted use so you know exactly what you can build.
