Santa Clara FAQ
Can I build an 8-foot fence for privacy?
Only with a building permit and potentially a variance. Standard side/rear limit without permit is 6 feet.
Why is my front fence limited to 3 feet?
Low front-yard limits preserve street visibility and the open character of residential neighborhoods.
Sunnyvale FAQ
Can I build an 8-foot backyard fence for privacy?
Yes, with a minor zoning clearance from Planning that confirms setbacks, neighbor notification, and no sight-distance impacts. Approval is usually administrative.
Does a trellis on top of a fence count toward the height?
Yes if it is solid. Open-lattice trellis above a 6-foot fence may qualify for higher limits but still needs Planning confirmation and cannot exceed 8 feet total.
