Maine fence laws require a legal fence to stand at least four feet tall and be kept in good repair, and when two neighbors both use their land, they share the cost of the fence between them equally. The rules live in Title 30-A, Chapter 133 of the Maine Revised Statutes, which also creates a formal dispute process handled by municipal officials called fence viewers. Local zoning and a separate spite-fence statute add more rules on top.
What Counts as a Legal Fence
Under Title 30-A, § 2951, a fence is legally sufficient if it stands at least four feet tall, is in good repair, and is built from rails, timber, stone walls, iron, or wire.1Maine State Legislature. Maine Code 30-A 2951 – Legal Fences Natural features count too. Brooks, rivers, ponds, creeks, ditches, and hedges can all serve as legal barriers along a property line without any construction at all.
Fence viewers also have discretion to approve other barriers they consider equivalent. If your fence uses a material or design that doesn’t fit neatly into the listed categories, the local fence viewers decide whether it qualifies. The four-foot height minimum and the good-repair standard apply regardless of the material.
Who Pays for a Shared Boundary Fence
When neighbors both use their land, Maine splits the cost of the partition fence between them evenly. Title 30-A, § 2952 requires occupants of enclosed lands to maintain the fence between their properties “in equal shares, while both parties continue to improve them.”2Maine State Legislature. Maine Code 30-A 2952 – Maintenance “Improve” here means actively using the land, whether for farming, a residence, or another purpose.
The duty runs year-round. Section 2957 requires partition fences to stay in good repair throughout the year unless both neighbors agree otherwise.3Maine State Legislature. Maine Code 30-A 2957 – Repairs You can’t let your section fall apart over winter and blame the season. A relaxed arrangement between neighbors is fine, but put it in writing.
When Land Use Changes
The equal-share rule shifts if one neighbor stops using their land. Under § 2960, if you stop improving your property or open up your enclosure, you can’t simply tear down your share of the partition fence. The adjacent neighbor has the right to keep it by paying you its fair value, as determined by two or more fence viewers.4Maine State Legislature. Maine Code 30-A 2960 – Occupant Ceasing to Improve Land; Adjoining Owner May Buy Fence
The reverse works the same way. Under § 2961, when someone starts using previously open land, they must pay half the value of any existing partition fence on the boundary. If the parties can’t agree on the value, fence viewers set it. The new occupant then has 30 days after demand to pay, or the fence owner can sue for the assessed value plus the appraisal cost.5Maine State Legislature. Maine Code 30-A 2961 – Liability of Owner Starting to Improve Land Lying in Common
The House-Lot Exception
The partition fence rules do not apply to house lots of half an acre or less, with a twist. If the owner of such a small lot improves it, the adjacent landowner must build and maintain half the fence between them, whether or not that adjacent owner uses their own land.6Maine State Legislature. Maine Code 30-A 2964 – Applicability to House Lots or Written Agreements The same statute confirms that any written agreement between neighbors about partition fences remains valid and overrides the default rules.
What to Do When a Neighbor Won’t Build or Repair
This is where Maine’s fence law has real teeth. If your neighbor refuses to maintain their share, § 2953 lets you file a complaint with two or more fence viewers in your town. The viewers must give notice to the delinquent party, inspect the fence, and if they find it insufficient, issue a written order directing the neighbor to repair or rebuild within a deadline of no more than 30 days.7Maine State Legislature. Maine Code 30-A 2953 – Neglect of Owners; Function of Fence Viewers
If the neighbor still doesn’t act, you can do the work yourself and collect double the value. Under § 2954, once you finish the fence and two or more fence viewers certify that it’s sufficient and assess its value, you can demand double that value plus the viewers’ fees from the delinquent neighbor.8Justia Law. Maine Code 30-A 2954 – Double Compensation for Building Fence If they don’t pay within one month of your demand, you can sue and collect interest at 1% per month on top of the doubled amount.
Section 2956 reinforces this remedy when fence viewers have formally assigned each neighbor a portion of the fence. You can do the work, recover double the value and expenses, and get a lien on the delinquent neighbor’s land, enforceable by attachment if you file within one year of the fence viewers’ division order.9Maine State Legislature. Maine Code Title 30-A Chapter 133 – Fences and Fence Viewers
How Fence Viewers Resolve Disputes
Fence viewers are the unsung officials of Maine property law. When neighbors disagree about who owes what for a boundary fence, either side can ask two or more fence viewers to sort it out. Under § 2955, they give reasonable notice to both parties, then assign each person their share of the fence in a written decision and set a deadline for building or repairing each assigned portion, capped at 30 days.9Maine State Legislature. Maine Code Title 30-A Chapter 133 – Fences and Fence Viewers
Once recorded with the town clerk, that written assignment binds both parties going forward. If one neighbor has already built and maintained more than their fair share, fence viewers can award the value of that excess, recoverable through a civil action if the other party doesn’t pay within six months.
The parties split fence viewers’ fees equally. If one side doesn’t pay their half within a month, the other can cover the full amount and sue the delinquent party for double their share.
Spite Fences
Building a tall fence purely to block a neighbor’s light or view crosses into nuisance territory. Under Title 17, § 2801, any fence or fence-like structure that exceeds six feet in height and is maliciously maintained to annoy an adjoining owner or occupant is classified as a private nuisance.10Maine State Legislature. Maine Code Title 17 2801 – Spite Fences The statute reaches more than traditional fences. Maine courts have held that dense hedges and rows of trees can qualify as fence-like structures.
Two elements must both be present: the structure must unnecessarily exceed six feet, and it must be kept for the purpose of annoying the neighbor. A useful eight-foot privacy fence that happens to bother someone next door isn’t automatically a spite fence. A ten-foot wall of plywood with no purpose other than blocking a neighbor’s ocean view is.
The typical remedy when a court finds a spite fence is an injunction ordering the owner to remove or modify the structure. Monetary damages are possible under general nuisance principles, though Maine courts have been conservative about awarding them. The neighbor bringing the claim carries the burden of proving malicious intent, which usually means evidence about the timeline, the structure’s utility, and any communications that show the builder’s motive.
Boundary Mistakes and Adverse Possession
Fences often end up marking boundaries that aren’t quite right. When a fence sits on the wrong side of the true property line for long enough, it can shift legal ownership of that strip through adverse possession. Maine requires 20 years of continuous, uninterrupted possession.11Maine Legislature. Maine Code 14 801 – Rights of Entry and Action Barred in 20 Years
A common defense is that the fence builder didn’t intend to claim the neighbor’s land and simply made a mistake about the line. Maine law eliminates that defense. Title 14, § 810-A provides that a mistaken belief about the boundary location does not defeat an adverse possession claim.12Maine Legislature. Maine Code 14 810-A – Mistake of Boundary Line If the possession was actual, open, and continuous for 20 years, intent doesn’t matter.
Before building a new fence, pay for a professional land survey. The cost is minor next to the legal headaches of discovering years later that your fence sits on the wrong side of the line.
Local Permits and Zoning
State law sets the baseline; your municipality almost certainly adds its own rules. Maine communities with populations over 4,000 must follow the Maine Uniform Building and Energy Code, which generally exempts fences under seven feet from building permit requirements. Smaller towns may or may not adopt building codes, so a call to your local code enforcement office is the essential first step.
Even where no building permit is needed, zoning ordinances frequently restrict fence height by location on the lot. The pattern across most Maine municipalities is predictable: front-yard fences are typically limited to four feet, while side and rear yards allow up to six. Many towns also require front-yard fences to use open designs like picket or split-rail rather than solid privacy panels.
Properties in special districts face additional scrutiny. Land within a designated historic district usually triggers design review regardless of fence height. Land within Maine’s shoreland zone, which extends 250 feet from the normal high-water line of rivers, great ponds, and other significant water bodies, may face restrictions under the state’s mandatory Shoreland Zoning Act. Homeowners associations add another layer, and their covenants can impose material, color, and height restrictions that go well beyond state law or local zoning. HOA rules generally function as private contractual obligations enforceable separately from any government regulation.
