Fremont, CA Landscaping Rules: Tree Trimming (2026)

Fremont Municipal Code Title VIII establishes a tree preservation ordinance protecting Heritage Trees (trunks 24 inches or more in diameter at breast height, or native oaks and sycamores 10 inches or more DBH) on private property. Routine light maintenance pruning is allowed, but major crown reduction, topping, or removal of over 25 percent of live canopy requires a Tree Removal or Encroachment Permit reviewed by the City Arborist. Topping is discouraged as it damages tree health and can void preservation status. Street trees (in the parkway strip) are city-owned; Public Works performs or approves all street tree pruning. Californians have a right to trim neighbor branches overhanging their own property line back to the line, but cannot damage the tree overall or enter the neighbor property. Commercial tree services must carry a Fremont business tax certificate.
