Pasadena Neighbor Fence Rules Rules (2026): What You Need to Know

California Civil Code Section 841 creates a statutory framework for the construction, maintenance, and cost-sharing of fences on or near the boundary line between two adjoining parcels. Under the statute, both neighbors are presumed to benefit equally from a shared boundary fence and are therefore presumed to be equally responsible for the reasonable costs of construction, maintenance, and replacement. Before beginning any boundary fence project that a neighbor will be asked to contribute to, the initiating party must provide the adjoining owner with written notice at least 30 days in advance. The notice must include: a description of the fence or wall proposed, including materials and location; an itemized estimate of construction costs; the proposed division of costs between the parties; and a statement of the neighbor's right to object or negotiate prior to construction. If the adjoining neighbor does not respond within 30 days, they may be presumed to have consented, but this is fact-specific and legal advice is recommended before proceeding.

In Pasadena, the Civil Code framework interacts with the City's design and zoning requirements. Even if two neighbors agree on a fence, it must still comply with Pasadena Municipal Code Chapter 17.40 height limits (3.5 feet in front yards, 6 feet in side and rear yards) and, for properties in historic districts, must receive Historic Preservation Commission design approval. A neighbor cannot be required by the Civil Code to share costs for a fence that exceeds city-allowed heights or that would be non-conforming. Disputes over fence costs that cannot be resolved privately may be submitted to the Pasadena City Attorney's Neighborhood Mediation program or pursued through Small Claims Court for amounts up to $12,500.
