Tree Protection in Los Angeles, CA

If you live in Los Angeles or are thinking about moving there, tree protection are one of those things you probably won't think about until they affect you directly. Los Angeles has 3 specific rules on the books covering different aspects of tree protection, and some of them might surprise you.

Parkway Planting

A Board of Public Works permit is required before planting, removing, cutting, or pruning any tree in a Los Angeles public street or parkway. Residential owners may replace shrubs and plants (but not trees) in their adjacent parkway without a permit if they follow the Board's Residential Parkway Landscaping Guidelines.

Key details: Permit required for: Planting, removing, cutting, pruning any tree/shrub in a City street. Residential exception: Shrubs and plants (not trees) may be replaced per Board guidelines without a permit. Edible plants permitted: Yes, in residential parkways per Board guidelines. Maintenance obligation: Owners must maintain parkway per Residential Parkway Landscaping Guidelines. Governing authority: Board of Public Works.

Removing a tree without a permit, or failing to comply with conditions imposed in a permit (e.g., required replacement planting), is a misdemeanor under LAMC § 62.170.

Protected Tree Species

Los Angeles protects four categories of Southern California native tree species, oaks (Valley Oak and California Live Oak and other indigenous oaks), Southern California Black Walnut, Western Sycamore, and California Bay, when they measure four or more inches in cumulative trunk diameter at 4.5 feet above the ground. No protected tree may be relocated or removed without City approval, and any act that causes the tree to die (including soil grading, toxic substances, or equipment operation near the root zone) qualifies as prohibited 'removal.'

Key details: Protected oaks: Valley Oak (Quercus lobata), California Live Oak (Quercus agrifolia), other California indigenous oaks: excluding Scrub Oak (Quercus dumosa). Other protected species: Southern California Black Walnut (Juglans californica var. californica), Western Sycamore (Platanus racemosa), California Bay (Umbellularia californica). Minimum qualifying size: 4 inches or more cumulative trunk diameter, measured 4.5 feet above the ground. Not covered: Licensed nursery stock; trees planted through a tree planting program. Replacement when removal approved: At least 2 protected-variety trees, 15-gallon minimum size, at least 7 feet tall.

Protected tree removal without Advisory Agency approval in a subdivision context violates LAMC § 17.05.R and can result in denial or revocation of subdivision map approval. Historical Monument trees must be retained at their existing location except when in danger of falling.

Heritage & Protected Trees

Los Angeles protects four indigenous tree species and two shrub species by ordinance; any specimen measuring four inches or more in cumulative diameter at 4.5 feet above the base requires a permit before it can be removed or relocated.

Key details: Protected trees: Oak (all indigenous species except scrub oak), Black Walnut, Western Sycamore, California Bay. Protected shrubs: Mexican Elderberry, Toyon. Size threshold: 4 inches cumulative diameter at 4.5 ft above base. Exemption: Licensed-nursery grown trees and planting-program trees. Code section: LAMC § 46.01.

Removing or relocating a protected tree without a permit is unlawful. Building permits on the property can be withheld for up to 10 years. Violating the conditions of an issued permit is a misdemeanor.

The Bottom Line

Los Angeles's tree protection rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Los Angeles is broadly strict or permissive.

These rules come from Los Angeles's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
