Fence height rules in Piedmont, California
Outside the street setback, a fence up to 6 feet tall needs no design review or building permit in Piedmont; taller fences need a design review permit (with neighbor notice above 8 feet). Any fence in the street setback, at any height, needs design review by the Planning Commission, and corner lots are limited to 3 feet in a 30-foot sight triangle.
| Side/rear fence, no review | Up to 6 feet [1] |
| Over 6 feet (side/rear) | Design review permit [1] |
| Over 8 feet | Design review with neighbor notification [2] |
| Fence in street setback | Design review at any height (Planning Commission) [3] |
| Corner-lot sight triangle | 3 ft max within 30 ft of the corner [5] |
| Building permit | Not needed for fences 6 ft or less [6] |
| Retaining wall without review | Up to 30 inches [8] |
Height limits by location
Piedmont regulates fences through design review rather than a single height cap (City Code section 17.32.010). Height is measured from existing or proposed grade, and a fence combined with a retaining wall within 24 inches counts as one structure.
- Side and rear yards (outside the street setback): a fence 6 feet or less is exempt from design review; over 6 feet requires a design review permit [1].
- Over 8 feet: design review plus neighbor notification under division 17.62 [2].
- Street setback (front or street-facing yard): any fence, at any height, needs a design review permit [3], and the Planning Commission (not staff) reviews it [4]. In Zone A the street yard setback is 20 feet.
- In Zones C and D, fences up to 8 feet are allowed where the property line is shared with single-family uses.
A fence includes railings, free-standing walls, lattice, trellises and covered gates, and no part may be wider than 24 inches in plan [7].
Corner lots
On a corner lot, no fence, wall, hedge or vegetation may be taller than 3 feet within a sight triangle measured 30 feet along the front and side lot lines from the corner, unless the Planning Commission approves otherwise [5].
Retaining walls
A retaining wall up to 30 inches needs no design review; taller walls do [8]. A series of terraced walls and fences at least 24 inches apart avoids review if no single wall exceeds the limits.
Permits
Piedmont's building code amendments exempt fences 6 feet or less from a building permit [6], but any improvement that requires design review also needs a building permit [9]. The code doesn't set a minimum distance from the property line or a required finished side; designs are judged against the Piedmont Design Standards and Guidelines.

Next steps
- Measure where the fence will go: inside the street setback, or in a side/rear yard.
- For a side or rear fence up to 6 feet, no city permit is needed; for taller fences or any fence in the street setback, apply for a design review permit at the Planning & Building Department, 120 Vista Avenue, (510) 420-3050.
- On a corner lot, keep everything within the 30-foot sight triangle under 3 feet.
- After design review approval, get a building permit before construction.

California state rules on fences
Fence height, location and design are mostly set by your city or county zoning code. A few state rules apply everywhere:
- Building permit: the California Residential Code (R105.2) exempts fences up to 7 feet high from a building permit. Pool barriers are not exempt. Zoning height limits still apply, and many cities cap front-yard fences well below 7 feet. Some cities have amended the exemption.
- Spite fences: under Civil Code §841.4, a fence or fence-like structure that unnecessarily exceeds 10 feet and is maliciously put up or kept to annoy a neighbor is a private nuisance. The neighbor can sue to have it removed.
- Good Neighbor Fence Act (Civil Code §841): since January 1, 2014, neighbors are presumed to share equally the reasonable cost of building, maintaining or replacing a fence between their properties, unless they agree otherwise in writing.
- Before spending money on a shared fence, you must give each neighbor 30 days' written notice. The notice must describe the problem, the proposed fix, the estimated cost, how costs would be shared, and the timeline.
- A neighbor can overcome the presumption in court by showing equal sharing would be unjust, for example because of financial hardship or costs driven by the other owner's aesthetic preferences.
- Pool fences must meet the Swimming Pool Safety Act's barrier standards when used as the pool enclosure (see Pools).
- Coastal zone: a new fence may need a coastal development permit, depending on the local coastal program.
