Summary
In the City of La Mesa, fences and walls are capped at four feet within the required front setback and six feet everywhere else on a residential lot, under Municipal Code Section 24.05.030(I). Taller fences need a special permit, and none can block the sight-distance triangle at intersections.
I.Fences and Retaining Walls. The height of any fences or walls (including any combination of freestanding fence or wall on top of a retaining wall) shall be measured from the midpoint between the finished surface grades on both sides of the fence or wall, measured along sections not exceeding ten feet in length.1.Fences or walls within the minimum front setback for a principal building shall not exceed four feet in height. Fences or walls in any other location shall not exceed six feet in height. However, fences or walls of greater height may be allowed by special permit, where topographic or other conditions reduce the effectiveness of normal height fences for privacy. In no case shall a fence or wall in an area required for sight distance visibility exceed the height established by this chapter to maintain such visibility.
Full Breakdown
Section 24.05.030(I) sets La Mesa's residential fence and wall standard, including any freestanding fence or wall stacked on top of a retaining wall. Height is measured from the midpoint between the finished grades on each side of the fence, checked in sections no longer than ten feet, which lets a fence step down gradually on a sloped lot rather than being measured from a single low or high point. Subsection (I)(1) caps fences and walls at four feet within the required front setback for the main house and at six feet everywhere else on the lot, but the planning commission can approve a special permit for a taller fence where topography or other site conditions reduce a standard-height fence's privacy value.
No fence or wall, regardless of a special permit, can exceed the height set for the sight-distance visibility triangle in Section 24.05.030(N): within fifteen feet of a street, alley, or driveway intersection, nothing over thirty-six inches above curb or pavement grade may obstruct the triangular sightline. Corner lots that back onto another corner lot's rear line get one added allowance under Section 24.05.030(I)(7): a six-foot fence is allowed within the reduced front setback there, still subject to the same sight-distance cap. Retaining walls in a required setback are separately limited under (I)(6) to a height needed to retain a three-foot fill or a six-foot cut.
Violations & Fines
Building a fence over four feet in a front setback or over six feet elsewhere without a special permit is a Title 24 zoning violation, enforced by the Community Development Department under the general penalty clause, Section 1.01.080. It is chargeable as a misdemeanor carrying up to a $1,000 fine, six months in county jail, or both, or as a civil land-use penalty of $50 per day for a noncommercial property or $100 per day for a commercial one, doubling on a repeat violation.
