Full Breakdown
170 sets the baseline that most El Cajon fence projects never need a permit to meet. A wall, fence or hedge up to 42 inches tall may sit anywhere on a lot, including in the front yard, with no zoning approval required. Behind the front yard line, that allowance jumps to six feet, except on a reverse corner lot, where anything over 42 inches must stay at least 10 feet from the side exterior property line so it does not block sightlines. Open metal fencing or heavy-gauge wire mesh up to six feet is also allowed by-right if it meets the section's construction specs: metal fencing needs open bar construction with at least four inches between elements, and nonmalleable wire mesh must be at least eight-gauge with openings no smaller than one inch, excluding chain link.
A property owner only needs a permit when a fence exceeds these by-right limits or uses a different material. 020(C), where the director may approve, conditionally approve or deny the request, or refer it to the planning commission. 220. 090, which bars anything over 42 inches within 15-foot legs of a corner lot's front and side lot lines.
