Full Breakdown
050(C)(2) sets the residential fence height table. In the required front yard area, fences are capped at 3 feet with no setback from the property line, but Table Note (3) allows a 6-foot fence if the top 3 feet is at least 90 percent visually open and transparent, such as a picket fence, open wood slats, or open wrought iron, including pilasters and lights built into the fence. Along required rear and interior side yards, fences can run the full 6 feet right up to the property line with no setback.
In the required street side yard, along corner side property lines, fences are also capped at 6 feet but must be set back 5 feet from the property line. All other areas of the lot allow a 6-foot fence with no setback. 140, with the setback location varying by the specific intersection geometry per Table Note (4). 030(A) from finish grade at the base to the uppermost point of the fence or wall. The designated approving authority can grant additional height through site development review, design review, or another discretionary entitlement for fences designed for noise attenuation or to screen a specific area or use, per Table Note (1). 050(C)(3).
Violations & Fines
A fence exceeding these height caps, most commonly a front yard fence over 3 feet without the 90 percent open top-three-feet exception, or any fence over 36 inches within the clear visibility triangle at an intersection, is subject to code enforcement action requiring the owner to lower, modify, or remove the noncompliant sections. Fences built to full height within the visibility triangle create a public safety hazard and are prioritized for correction since they obstruct sightlines for drivers and pedestrians.
