The Short Answer
Maine has no state law requiring a survey before building a fence. You are not legally obligated to hire a surveyor before you start digging post holes. But that does not mean skipping the survey is the right move. For many Maine properties, skipping it creates substantially more risk than the cost of the survey would justify.
Why Maine Boundaries Are Riskier to Assume Than You Think
Colonial-Era Deed Descriptions
A substantial portion of Maine residential properties outside of modern platted subdivisions have deed descriptions rooted in colonial and 19th-century land grants. These metes-and-bounds descriptions often reference physical features that have changed or disappeared entirely. A stone wall noted in an 1890 deed may have been removed. A brook referenced in a 1920 conveyance may have been rerouted.
Without a current survey, no map, no online lot map, and no reading of the deed itself tells you with legal certainty where the physical boundary sits today. The gap between where a property owner assumes the line is and where the licensed surveyor finds it can be several feet in either direction.
Missing and Buried Corner Monuments
Corner monuments on older Maine properties are often missing, buried under decades of accumulated soil and moss, or removed during road construction and landscaping projects. The absence of a visible monument does not mean the boundary is where the last fence was built or where the lawn grass stops. A fence built to an informal assumed line can easily encroach on the neighbor's land.
Rocky Ledge and Irregular Lot Shapes
Maine's bedrock geology and terrain history produced many irregular lot shapes, particularly in coastal communities and rural areas where land was divided along topographic features rather than a regular grid. A lot that looks roughly rectangular on a tax map may have a boundary that jogs around a granite outcrop or runs along a former stream course.
Maine Fence Laws and Local Regulations
The Maine Partition Fence Law
Title 17 MRSA contains Maine's partition fence provisions, which govern shared boundary fences between adjacent agricultural properties. These statutes address responsibility for maintaining division fences between farm fields and pastures where livestock are involved. For most residential fence situations in Maine, these provisions apply only if the adjacent land is actively farmed.
Local Zoning Ordinances
Fence height limits, materials, and setback requirements in Maine are governed by local municipal zoning ordinances rather than state law. Each town and city sets its own rules. Before building a fence, check with your municipality's code enforcement officer to confirm what, if any, permit is required and whether height or setback rules apply in your zoning district.
Shoreland Zoning
Maine's Mandatory Shoreland Zoning Act applies to land within 250 feet of tidal water, rivers, streams, ponds, and wetlands above a certain size. Shoreland zoning typically restricts structures and clearing in this buffer zone. Fences within the shoreland zone may require a permit, and some fence types may be prohibited entirely. If your property fronts tidal water or a significant water body, confirm shoreland zoning requirements before starting any fence project.
What a Survey Gives You Before You Build
- A certified determination of where the property line sits, with legal standing
- Physical monuments set or confirmed at each corner
- A document you can reference if a dispute arises later
- Confirmation that the planned fence line complies with local setback requirements
Some surveyors will stake the fence line at your request, placing temporary stakes along the boundary between corner monuments so you can see exactly where to run the fence. Ask whether this service is included or available as an add-on when you request quotes.
The Bottom Line
Maine law does not require a survey before building a fence, but the practical risk of skipping it is higher here than in most states. A residential boundary survey in Maine costs $400 to $1,200 for standard lots, often less than a single hour of attorney time if a dispute ends up in court.
