Upland, CA Fence Regulations: Neighbor Fence Rules (2026)

Upland's Municipal Code (Chapter 17.13) regulates how a fence on or near a property line may look and how tall it may be, but it does not assign financial responsibility between neighbors. Cost-sharing for a shared boundary fence is a matter of California state law. Under California Civil Code Section 841 (the Good Neighbor Fence Act of 2013), adjoining landowners 'are presumed to share an equal benefit from any fence dividing their properties and, unless otherwise agreed to by the parties in a written agreement, shall be presumed to be equally responsible for the reasonable costs of construction, maintenance, or necessary replacement of the fence.' A landowner who intends to incur such costs 'shall give 30 days' prior written notice to each affected adjoining landowner.' That notice must include the presumption of equal responsibility, a description of the problem, the proposed solution, the estimated cost, the proposed cost-sharing approach, and the proposed timeline. A neighbor can rebut the equal-split presumption by showing it would be unjust. Practically, in Upland this means: place and build the fence to meet Chapter 17.13's 6-foot residential cap and 3.5-foot front-yard cap, and follow Civil Code 841's notice process for cost-sharing. Boundary-line and trespass disputes are civil matters; the City enforces zoning standards, not private property-line disagreements.
