Rialto, CA Fence Regulations: Fence Requirements (2026)

San Bernardino County's Development Code imposes several affirmative fencing and wall requirements in the unincorporated area in addition to height limits. Under Section 83.06.050 (Walls Required Between Different Land Use Zoning Districts), where a nonresidential district abuts a residential district, or a multiple-residential district abuts a single-residential district, a solid masonry wall must be built on the boundary line consistent with the heights in Table 83-6; where an industrial district abuts a non-industrial district, a solid masonry wall a minimum of 6 ft in height is required. These walls must be of solid masonry construction and of a decorative design when visible from public rights-of-way, subject to the Director's approval, though the Director may waive or modify the requirement where a conforming wall already exists. Section 83.06.060 (Special Wall and Fencing Requirements) requires that swimming pools, spas, and similar features be fenced in compliance with the California Building Code; that screening of outdoor uses and equipment comply with Section 83.02.060; that temporary fencing protecting archaeological, historic, or tree resources be approved by the Director; and that walls along rights-of-way be built of decorative concrete or masonry up to 6 ft in height with an appropriate mix of materials and landscaping. All fences must also comply with the height limits in Section 83.06.030 and the material prohibitions in Section 83.06.070.
