Newport Beach Height Limits Rules (2026): What You Need to Know

The Short Version

Newport Beach Zoning Code Section 20.30.040 establishes maximum height limits for fences, walls, and hedges based on their location on the property relative to setback areas. In residential zones, fences and walls in the front yard setback area are limited to 3 feet in height (measured from the adjacent finished grade). In the side and rear yard setback areas, fences and walls may be up to 6 feet in height. On corner lots, sight visibility triangles at intersections require fences within the triangle area to be no taller than 3 feet to maintain traffic safety sight lines. The Zoning Code allows an additional 2 feet of open lattice, trellis, or similar non-solid material on top of a 6-foot solid fence in side and rear yards, for a maximum combined height of 8 feet with the open extension. Retaining walls are measured separately; when a retaining wall supports a fence on top, the combined height of the retaining wall and fence is regulated and may require a modification permit if it exceeds the applicable zone limit. Properties along bluffs or coastal areas may be subject to additional height restrictions under the Local Coastal Program to protect public views. Newport Beach's hilly terrain in neighborhoods like Harbor View Hills, Newport Coast, and Cameo Highlands frequently creates situations where grade changes affect fence height measurements. The Zoning Code specifies that measurements are taken from the lower of the two adjacent finished grades, which can be a significant consideration on sloped lots. Property owners should consult the Community Development Department before building fences on properties with significant grade changes.
