Tree Trimming: Anza vs Corona

Tree trimming on private property is generally unregulated in unincorporated Riverside County except where trees overhang county road right-of-way, block sight distance, or are within utility easements. Heritage and native oak protections apply in designated hillside areas. Trees within 10 feet of chimneys must be trimmed under Public Resources Code §4291.

CMC Chapter 12.40 makes property owners maintain parkway street trees with 8 ft sidewalk and 14 ft street clearance. A free Public Works permit is required to remove or heavily prune street trees.
