Simi Valley, CA Fence Regulations: Material Restrictions (2026)

The Simi Valley Development Code restricts certain residential fence materials. As cited by the City's Planning Division, chain-link fences are not allowed pursuant to SVMC Section 9-30.030.A.6.e. Standard accepted materials for residential property line walls and fences include masonry block (often slumpstone), stucco-finished walls, wrought iron, wood board, and vinyl board. The Planning Division evaluates material and location for compatibility with adjacent properties when issuing the Zoning Clearance required before construction. California Civil Code Section 841 (the Good Neighbor Fence Act, AB 1404, effective January 1, 2014) also governs cost-sharing for boundary fences between adjoining residential owners: adjoining landowners are presumed to share an equal benefit from any fence dividing their properties and, unless otherwise agreed to by the parties in a written agreement, are presumed equally responsible for the reasonable costs of construction, maintenance, or necessary replacement of the fence. A landowner who plans to do fence work must give 30 days' prior written notice to the adjoining landowner before incurring costs.
