Yuba County, CA Fence Regulations: Retaining Walls (2026)

Retaining walls are handled under the grading rules of Chapter 11.23, not the fence height table. Section 11.23.020(A)(2)(a) requires a grading permit for retaining walls which are over four feet in height, as measured from the bottom of footing to the top of the wall, and Section 11.23.020(A)(2)(b) separately requires a permit for any retaining walls that are subject to surcharge (additional lateral load, such as a slope or structure above the wall). Conversely, the grading exemptions in Section 11.23.020(B) list retaining walls less than four feet in height (bottom of footing to top of wall) and not subject to surcharge as exempt from the grading permit. Walls that double as fences must also satisfy the height limits and visibility standards in Section 11.19.040, and any wall near a levee must meet the levee setback requirements of Section 11.23.030.D. Because walls over four feet and surcharged walls involve structural and drainage concerns, engineered plans are typically required. Confirm specific requirements with the Yuba County Community Development and Services Agency before construction.
