Concord FAQ
Do hedge rules match fence rules?
Yes when the hedge functions as a boundary barrier. Ornamental landscaping outside of the fence function may be treated differently.
Can my neighbor force me to trim my hedge?
Yes if it crosses the property line, blocks sightlines, or overhangs sidewalks. Otherwise disputes are private and typically resolved in Small Claims Court.
What if my hedge blocks the sidewalk?
You must maintain 8 feet of vertical clearance over public sidewalks. Code Enforcement can require trimming under Streets & Highways Code §5610.
El Cerrito FAQ
Can I grow a 15-foot hedge along my property line?
In principle yes — hedges are not capped at fence heights — but a tall hedge built maliciously to block a neighbor could be challenged as a spite fence under Civil Code §841.4.
Can I trim my neighbor's hedge overhanging my yard?
You can trim back to the property line at your own expense without damaging the plant's health. You cannot enter their property without permission.
