Rocklin, CA Fence Regulations: Fence Requirements (2026)

Under Placer County Zoning Ordinance Section 17.54.030 (Landscaping and fencing), screening fencing or walls are required in connection with certain new development, separate from the general height limits that apply to private residential fences. The code calls for fencing that forms an opaque screen, such as solid wood fencing, a masonry wall, or other materials forming an opaque screen, to be constructed and maintained with new development, in addition to any fencing required by building codes or state or federal law. For commercial and industrial sites that abut a zone district that is not commercial, industrial, or professional office, a minimum six-foot solid wall or fence (up to a maximum eight-foot solid wall or fence for storage-yard areas), or a combination of landscaping, berm, and fencing, must be provided on the side and rear property lines. Fencing, walls, or landscaping required by the county as a condition of project approval may be six feet high, or another height required to mitigate noise or for aesthetic reasons. Required fences must be maintained over time. Clear-view-triangle restrictions limit fence height at corner lots for traffic safety. Because requirements depend on the project type, zone, and adjacency, applicants should confirm specifics with Placer County CDRA Planning during project review.
