Portland follows Oregon's boundary fence statute (ORS 97.130). Responsibility for shared boundary fences is governed by state law. Oregon does not mandate cost-sharing by default, but neighbors can negotiate shared fence agreements. Property surveys are recommended before fence installation.
Oregon Revised Statute 97.130 governs partition fences between adjoining properties. Portland's Zoning Code (Title 33) does not add specific neighbor-notification requirements beyond state law for residential fence construction. Homeowners should obtain a property survey to determine exact property lines before building near boundaries. Encroachment on a neighbor's property can create legal liability. Disputes over fence location are civil matters. Portland does not have a mandatory fence cost-sharing ordinance. For ADU and swimming pool fences, zoning and building code rules apply regardless of neighbor agreement.
Civil remedy for property line disputes. Small claims court for disputes under $10,000. Nuisance action for spite fences.
