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

The City of Fremont regulates fence and wall heights through the Zoning Ordinance administered by the Community Development Department's Planning Division. Height limits vary based on the location of the fence on the property — front, side, or rear yard — and the type of material used.

In single-family residential zones (R-1), front yard fences and walls are limited to three feet (thirty-six inches) in height if they are solid (wood, masonry, vinyl, or other opaque material). Fences constructed of open materials that maintain at least fifty percent visibility — such as wrought iron, tubular steel, chain link, split rail, or picket fences with adequate spacing — may be up to four feet in height in the front yard. The front yard is defined as the area between the front property line and the front building setback line, which varies by zoning district but is typically twenty feet in R-1 zones.

Side yard and rear yard fences may be up to six feet in height, measured from the finished grade on the higher side of the fence. Where a side yard or rear yard fence transitions into the front yard setback area, the fence must step down to the applicable front yard height limit. This transition often requires a tapered or stepped design to comply with both height limits.

On corner lots, the sight-line triangle provisions require that fences within a triangular area formed by the property lines along each street frontage and a line connecting points fifteen feet from the corner intersection on each frontage be limited to three feet in height. This requirement ensures that drivers and pedestrians have adequate visibility at intersections — a safety concern in Fremont's many residential neighborhoods with moderate traffic volumes.

Retaining walls are measured from the lower finished grade to the top of the wall. A retaining wall combined with a fence on top is measured for total combined height. Retaining walls exceeding four feet in height generally require a building permit and engineered plans. Fences placed on top of retaining walls may be subject to reduced maximum heights depending on the total combined height and setback from the property line.

Property owners seeking to exceed the standard height limits may apply for a Zoning Administrator Exception or a variance through the Community Development Department. The review process requires a finding that the requested height is necessary due to unusual site conditions and will not adversely affect neighboring properties.
