Retaining walls in Pico Rivera require building-permit review under the Title 15 building regulations, and any fence placed on top of a retaining wall must still satisfy the Zoning Code fence-height limits in Section 18.42.050 measured from the finished grade of the subject property.
Pico Rivera treats retaining walls as structures subject to permit and engineering review under the city's Title 15 building regulations, which adopt the California Building and Residential Codes. Retaining walls that support a surcharge or exceed the code height threshold require an engineered plan and building permit through the Building Division. Where a fence sits atop a retaining wall, the fence portion is measured against the Zoning Code fence-height standards in PRMC 18.42.050 (Note 32), which cap fences at 4.5 feet (non-solid) or 3.5 feet (solid) in the front-yard setback and 6 feet behind it, measured from finished grade. Because grade and wall configurations vary, confirm the permit path and fence-height measurement with the Building and Planning Divisions first.
Building an unpermitted retaining wall, or a wall-plus-fence combination that exceeds the zoning fence-height limit measured from finished grade, can result in correction notices, engineering review, and code-enforcement action.
