Types of easements
How wide is a utility easement?
Ten to twenty feet covers most residential utility strips, with buried service lines commonly at ten feet and overhead distribution at twenty. Transmission and pipeline corridors are far wider.
Width follows the work the holder has to do, not the size of the pipe or wire. A crew needs room to dig, stack spoil, stand beside the trench and bring in equipment, which is why a two inch cable can sit in a ten foot strip and a deep sewer can justify thirty or forty feet.
Utilities draft from standard forms, so the same numbers repeat across the country: ten feet for buried service, fifteen to twenty for gas mains and water mains, twenty for a pole line, twenty for a residential shared driveway, fifty for a transmission pipeline, and a hundred or more for high voltage transmission.
None of that overrides your document. A plat note or a negotiated grant can set any width the parties agreed to, and older grants sometimes state no width at all. The recorded dimension is the one that governs what you can do.
What this looks like in practice
The width in your document was chosen by whoever drafted the grant, usually from a standard company form, and it reflects the room a maintenance crew wants rather than the footprint of the equipment. That is why a slim buried cable can carry a ten foot strip and a deep gravity sewer can carry forty.
Older grants are the awkward ones. Some describe a right to lay and maintain lines with no dimension at all, leaving the practical width to be inferred from the facility and reasonable maintenance needs. Those cases are worth a survey and, if you are planning to build, a written confirmation from the holder.
What to do next
- 1Find the dimension on the plat or in the recorded grant and note whether it is centered on the facility.
- 2Locate the physical facility with an 811 utility locate before measuring anything on the ground.
- 3Check whether more than one provider shares the same platted strip.
- 4For construction plans, confirm the width and any setback in writing with the holder before you order materials.
What to look for
- The dimension written on the plat or in the recorded grant, in feet.
- Whether the width is centered on the facility or measured from a lot line.
- Whether several utilities share one platted strip.
- Any temporary construction easement alongside the permanent one.
Questions people ask next
Can a utility widen an existing easement?
Not unilaterally. Widening usually requires a new or amended recorded grant, which means your agreement and, ordinarily, compensation.
Is the easement centered on the pipe or the wire?
Often but not always. Some grants measure from a lot line, a road right-of-way, or a platted boundary, which can put the facility off-center inside the strip.
General educational reference only. Prescription periods and their exceptions change, and several states set the period by case law rather than by statute. Read the linked official code and consult a licensed attorney in that state before relying on any of it.
