Tustin, CA Fence Regulations: Height Limits (2026)

Tustin City Code § 9271i(1) sets a uniform 6'8" height ceiling for fences, solid hedges and walls on or within rear and side property lines, on interior lot lines, and behind the front yard setback line, and that ceiling applies in every zoning district in the city, not just residential ones. Inside the required front yard setback itself, the limit drops sharply: nothing three feet or taller may be erected there at all, which keeps sightlines open along the street. Fences and walls in a required rear or side yard near a street, alley or driveway intersection have to meet the visual clearance standards set by the Community Development Director and Public Works Director, addressing the corner sightline hazard directly.

The section allows an exception for fences, walls or hedges up to 20 percent taller than 6'8" enclosing the rear half of a lot, but only through a minor adjustment approved under § 9299b(1); a Conditional Use Permit under § 9291 can waive or modify the standard height rule more broadly. The height and setback rules do not apply to a fence or wall that a State law or agency, or another City ordinance, requires for public safety, and all fences must be measured and built to the Building Department's development standards under § 9271i(4).
