Alaska Has No Formal Fence Viewer Law
Many states have a 'fence viewer' system, where a designated official helps neighbors resolve fence line disputes. Alaska is not among them. The state has no formal fence viewer statute, which means there is no government process to call when you and a neighbor cannot agree on where a fence should go. Disputes about fence placement are private matters, resolved through a licensed survey or, if that fails, civil litigation.
This absence of a formal system makes it even more important for Alaska property owners to get a boundary survey before building a fence. Without a survey, you are relying on your own estimate of where the property line is, and that estimate has no legal weight if a dispute arises later.
Trespass Risk Under AS 09.45
Alaska Statutes AS 09.45 governs trespass to real property. When a fence is built on a neighbor's land, that fence is a trespass. The neighbor is entitled to demand its removal, and if the fence owner refuses or delays, the neighbor can seek a court order and potentially recover damages.
The cost of a boundary dispute almost always exceeds the cost of a survey done before construction. A boundary survey for a typical residential lot in Anchorage ranges from $800 to $1,500. An encroachment dispute, by contrast, can involve attorney fees, court costs, surveyor fees for litigation support, and the expense of removing and rebuilding the fence in the correct location. Getting the survey first is the straightforward financial choice.
Old Fence Lines Are Not Legal Boundaries
In Alaska's rural areas, including agricultural land in the Matanuska-Susitna (Mat-Su) Valley and remote Interior parcels, fence lines that have been in place for decades are often treated informally as property boundaries. This is understandable, since in remote areas the original survey corners may be difficult to find and the cost of a survey has historically felt prohibitive.
The legal problem is that an old fence line has no inherent standing as a property boundary in Alaska. A fence installed without a survey, even one that has stood for many years, does not establish the legal boundary between two parcels. To become a legal boundary, an old fence line would need to meet the specific requirements for adverse possession or boundary by acquiescence under Alaska law, which requires a court finding, not just the passage of time.
In practice, this means that when a Mat-Su Valley property changes hands, an old fence line that seemed settled for decades can suddenly become a dispute. The new buyer's lender or title company may require a survey, and that survey may reveal that the fence is not on the legal boundary. The cost and conflict that follow are preventable.
Rural PLSS Section Lines and Fence Deviations
In areas covered by the Public Land Survey System (PLSS), rural parcel boundaries follow section lines and their subdivisions. These lines were established by federal surveyors, in many cases more than a century ago, and the original BLM General Land Office (GLO) corners mark their locations. In the decades since, property owners and their predecessors have sometimes placed fences based on rough estimates of where section lines run rather than located BLM corners.
The result is that in many rural areas of Alaska, old fence lines deviate significantly from the true section lines. Deviations of several feet or more are common, and in some cases a fence may be off by a full chain (66 feet) or more. Without locating the original BLM corners and measuring from them, there is no way to know how far a fence deviates from the legal boundary.
A licensed PLS researches BLM cadastral records, locates the controlling corners in the field, and measures the boundary from those corners. This process tells you exactly where your legal boundary is and how it compares to any existing fence line before you invest in new fence construction.
Growing Suburban Areas Face Increasing Fence Disputes
As suburban development has expanded in the greater Anchorage area and the Mat-Su Valley, property lines have become more consequential. In established Anchorage neighborhoods, lots are smaller and closer together, meaning a fence that is even a foot or two off the legal line can create a significant encroachment. As the Mat-Su Valley has grown from a rural agricultural region into a more densely developed suburban area, similar pressures have emerged.
In developing Fairbanks suburbs, where newer subdivisions adjoin older rural parcels, boundary uncertainty can arise at the transition between different survey systems. A fence built without a survey in these transitional areas has a meaningful chance of being in the wrong location.
What Happens If a Neighbor Disputes Your Fence
If a neighbor challenges the location of your fence, the first step is to hire a licensed PLS to perform a boundary survey. The survey will establish the correct legal boundary based on recorded plats, deeds, and field monuments. If the survey shows your fence is on your property, you have documentation to support your position. If the survey shows the fence encroaches, you know the extent of the problem and can address it before the dispute escalates.
In some cases, neighboring property owners can agree in writing to a boundary location that differs from the surveyed line through a formal boundary line agreement. Such agreements should be prepared with legal counsel and recorded with the district recorder to be binding on future owners. This is a structured legal process, not an informal handshake arrangement.
Getting a Survey Before You Build
The practical recommendation for any Alaska property owner planning to build a fence is to have a boundary survey completed first. This is especially true for rural and semi-rural properties, properties that changed hands recently without a new survey, and any property where the location of existing monuments is unknown.
A survey gives you a set of clearly marked boundary points to guide fence construction. It protects you from trespass liability. It protects your investment in fence materials and installation. And it prevents the kind of neighbor dispute that can become costly and damage long-term relationships.
Our Alaska surveyor directory lists licensed firms across Anchorage, the Mat-Su Valley, Fairbanks, Juneau, and Sitka. You can find a surveyor near your property and request a quote for a boundary survey before your fence project begins.
