The Short Version
Shared fences between neighboring properties in Newport Beach are primarily governed by California Civil Code Section 841, known as the Good Neighbor Fence Act of 2013. This state law establishes that adjoining landowners are presumed to share equally in the responsibility for the reasonable costs of construction, maintenance, and replacement of boundary fences. The presumption of equal cost-sharing applies unless the parties have a written agreement stating otherwise, one party has been granted a court exception, or the boundary fence was not installed at the request of or with the agreement of both parties. Under the Good Neighbor Fence Act, a property owner who wants to build or replace a shared boundary fence must provide the adjoining owner with a 30-day written notice that includes a description of the proposed fence, the estimated cost, and a proposed timeline. The notice must be delivered by certified mail or personal delivery. If the adjoining owner does not respond within 30 days, the proposing owner may proceed and seek reimbursement for up to 50% of the reasonable cost through Small Claims Court. If the adjoining owner objects or proposes alternatives, the parties should negotiate in good faith before either party may proceed unilaterally. Newport Beach's local zoning code (NBMC Title 20) supplements the state law by establishing maximum height limits, material standards, and setback requirements for boundary fences. All shared fences must comply with the city's Zoning Code provisions for the applicable zone, including the 6-foot maximum height in side and rear yards and the 3-foot maximum in front yard setback areas. While the city does not mediate private fence disputes between neighbors, the Community Development Department can clarify applicable zoning requirements. Private fence disputes are civil matters resolved through negotiation, mediation, or the courts.

What Happens If You Violate This?
The Good Neighbor Fence Act is a civil statute, not a criminal ordinance, so enforcement occurs through civil litigation rather than municipal citations. A property owner who incurs fence costs and seeks reimbursement from an uncooperative neighbor may file a claim in Small Claims Court (for amounts up to $12,500) or Superior Court. The court may award up to 50% of the reasonable cost of the fence to the proposing party, plus court costs. Separately, if a shared fence violates Newport Beach Zoning Code height limits, setback requirements, or permit requirements, the city may issue Code Enforcement violations to both property owners, as the fence is on or near the shared boundary. Administrative citation fines start at $100 and escalate for non-compliance. Property owners should ensure any shared fence project complies with both state law and local zoning requirements.
