Understanding property boundary laws, fence regulations, and dispute resolution in Oregon.
Oregon property line laws reflect the state's stark geographic divide at the Cascade Range. West of the Cascades, dense forest and closed-range rules dominate, while the dry eastern side maintains open range traditions. With one of the largest timber industries in the nation, timber boundary disputes carry enormous financial stakes, and the state's treble damages statute for timber trespass is among the most frequently invoked in the country.
Fence laws determine who is responsible for building and maintaining boundary fences between neighboring properties. In Oregon, understanding these rules can prevent costly disputes with neighbors.
Oregon follows: closed range west of Cascades, open range east
Oregon has a geographic split in its fence law. Western Oregon (west of the Cascades) is generally closed range, while eastern Oregon is open range. Under ORS § 607.010 et seq., adjoining agricultural landowners share partition fence responsibilities. In open-range areas, landowners must fence livestock out.
Oregon's partition fence statutes allow a landowner to give written demand to an adjoining owner to build or maintain their share of a boundary fence. County courts can appoint fence viewers to resolve disputes over fence obligations.
Oregon does not have a specific spite fence statute. Courts may apply general nuisance principles, and local zoning codes typically regulate fence heights and materials.
Adverse possession is a legal doctrine that allows someone to claim ownership of land they have occupied openly and continuously for a certain number of years. Understanding these rules is important for protecting your property rights.
Statute of Limitations: 10 years in Oregon
Claimant must demonstrate actual, open, notorious, continuous, hostile, and exclusive possession for 10 years. Oregon requires that the use be inconsistent with the true owner's rights and that the claimant honestly believed the land to be theirs (ORS § 105.620).
If you are a property owner in Oregon, knowing the adverse possession period helps you understand the importance of monitoring your boundaries and addressing encroachments promptly. Regular boundary checks can help protect your ownership rights.
Timber trespass occurs when someone cuts, removes, or damages trees on another person's property without permission. Oregon law provides significant penalties to deter this behavior and compensate affected property owners.
Penalty: triple damages
ORS § 105.810 provides for treble damages for willful timber trespass. Given Oregon's massive timber industry, this statute is frequently invoked. Double damages are available for casual or involuntary trespass.
To avoid accidental timber trespass, always verify your property boundaries before clearing trees or brush near boundary lines. Even unintentional cutting on a neighbor's land can result in significant liability.
Boundary disputes between neighbors are common and can arise from unclear property lines, encroaching structures, or conflicting surveys. Oregon offers several paths to resolve these disagreements.
Boundary disputes are resolved through circuit court. Oregon courts consider survey evidence, the doctrine of acquiescence, and timber boundary markers. In timber country, boundary line precision is critical due to the high value of standing timber.
Quiet title actions are filed in circuit court under ORS § 105.605 et seq. Oregon's 2011 amendments to adverse possession law require the claimant to prove their claim by clear and convincing evidence.
The best way to prevent boundary disputes is to know exactly where your property lines are. Having a clear understanding of your boundaries before issues arise saves time, money, and relationships with neighbors.
An easement grants someone the legal right to use a portion of your property for a specific purpose. Understanding the easements that affect your land is essential for knowing your full property rights.
Common easements include utility easements, timber road access easements, beach access easements under Oregon's Beach Bill, irrigation ditch easements, and conservation easements. Oregon's public beach access law creates unique coastal easement situations.
Prescriptive Easement Period: 10 years in Oregon
A prescriptive easement can be established when someone uses a portion of your property openly and continuously for the statutory period without your permission. Like adverse possession, monitoring your property boundaries regularly can help prevent prescriptive easement claims.
Knowing your exact property lines is the foundation of protecting your rights under Oregon law. Here are the most common ways to determine where your boundaries are:

Oregon requires 10 years of actual, open, notorious, continuous, hostile, and exclusive possession. The claimant must have honestly believed they owned the land, and the claim must be proven by clear and convincing evidence.
Oregon is split geographically. West of the Cascade Range is generally closed range, where livestock owners must contain their animals. East of the Cascades is largely open range, where landowners must fence livestock out.
Under ORS § 105.810, you can recover treble (triple) damages for willful timber trespass, or double damages for casual or involuntary trespass. Given the high value of Oregon timber, these damages can be substantial.
