Full Breakdown
The zoning ordinance's Chapter 5.50 design-review exemption list excludes fences 3 feet or less in height, and "open" fences that are no more than 25 percent solid when viewed head-on and meet the § 4.20.050 height limits, from needing design review. Fences that exceed the district's height cap, sit in a "-d" or "-sr" combining district, or serve as tennis-court or sports-court enclosures beyond the normal height limit instead go through Zoning Administrator design review or administrative approval under §§ 4.20.050 and 5.50.060. This is the operative approval trigger for fences in the unincorporated area; the county does not require a separate building permit for a standard fence within the height limit.
Violations & Fines
Building a fence above the applicable height limit, or inside a "-d"/"-sr" combining district, without securing the required design review approval is a zoning violation and the county can require the fence reduced or removed.
