Simi Valley requires property owners to maintain trees so they do not encroach on public sidewalks, streets, or neighboring properties. The city has a tree preservation ordinance protecting certain native and significant trees from unauthorized removal.
Property owners in Simi Valley must trim trees to maintain minimum clearances: 8 feet over sidewalks and 14 feet over streets. Trees must not obstruct street signs, traffic signals, or streetlights. Dead limbs and branches that pose a safety hazard must be promptly removed. The city's tree preservation ordinance protects native oaks, significant trees, and heritage trees from unauthorized pruning that would compromise the tree's health. Street trees in the public right-of-way are maintained by the city's Public Works Department; residents should not prune city trees without authorization. Professional arborists following ISA standards are recommended for significant pruning work.
Failure to maintain tree clearances results in Code Enforcement notices with deadlines for trimming. Trees that damage city infrastructure (sidewalks, utilities) may be trimmed by the city at the owner's expense. Unauthorized pruning or removal of protected trees carries significant fines under the tree preservation ordinance.
