Chino Hills, CA Tree Protection: Tree Removal Permits (2026)

Chino Hills' tree-protection permit framework lives in CHMC Chapter 16.90 (Tree Preservation), backed by CHMC Chapter 12.26 (City-Owned Trees) for public trees. It is unlawful to destroy or remove a protected tree on undeveloped property or designated developed property without a Tree Removal Permit. Protected native trees are California Sycamore, California Live Oak, California Black Walnut, and Coastal Scrub Oak that are publicly visible and four inches or greater DBH (measured at 4.5 feet). Heritage trees are any single- or multi-trunk tree with a cumulative diameter of 44 inches or greater DBH of significant age, health, and quality as judged by a City-approved certified arborist; heritage trees on new development also require permits. A key procedural rule: when a tree-removal permit is required, no grading or building permit may be issued, and no removal work on a non-exempt protected tree may begin, until the tree permit is issued. Applications go through the Community Development Department using the Tree and Plant Removal Application. Pruning a protected tree does not require a permit but must follow ISA standards. Separately, City and parkway trees may never be removed by residents - only the City removes public trees, and damaging a City tree violates CHMC 12.26.100. This is a robust city ordinance that exceeds default protections.
