Things To Consider When Looking for Tree Service in Malibu

We provide the best in tree services in Malibu, CA! In Malibu's coastal location, wildfire-prone hillsides, and strict environmental regulations create unique challenges for those seeking tree trimming, pruing or removal. At Ventura Tree Services, these are some of the most common issues homeowners and property managers face in Malibu. These often stem from the need to balance tree health, fire safety, and compliance with city rules protecting native species.

There is Strict Permitting for Protected Trees -- Trimming or removing any native trees (oak, sycamore, alder, walnut, toyon) with trunks over 6 inches in diameter requires the City Biologist’s approval. Any quick, or “over-the-counter” permits are available only for health/safety risks confirmed by a licensed arborist. Malibu's Local Coastal Program prioritizes habitat preservation. Any work that is done without authorization can lead to fines up to $10,000+ and/or restoration orders. The entire city of Malibu is a Fire Hazard Severity Zone. However, permits aren't waived for fire preparation at all. You must consult the City Biologist early via malibucity.org, or get an arborist's report for unstable trees. Its possible to search property records for existing Coastal Development Permits (CDPs) that may affect rules.

Fire Hazard Compliance and Fuel Modification -- All trees must be trimmed to create defensible space against fire (e.g., no branches within 10 feet of structures), but Los Angles County Fire Department (LACoFD) approval is needed for plans in high-risk zones. Frequent wildfires make improper trimming a liability; overgrown trees near homes exacerbate spread, but excessive cutting can violate environmental rules. Landscape plans must be submitted to LACoFD’s Fuel Modification Unit. We suggest you hire a certified arborist for compliant pruning, trimming, and shaping. Annual inspections by a competent tree service can help avoid violations.

Poor-Quality or Unlicensed Services -- We have seen many “hack jobs" by cheap tree service crews leading to tree death, pest infestations, or structural damage. Strong and steady coastal winds and pests (such as boring insects) amplify tree care errors. We recommend that you avoid "budget" services. Expect to pay $500–$2,000+ for professional work, especially on large estates.

Pest, Disease, and Nutrient Deficiencies -- Palms and many natives are prone to insects (e.g., palm weevils), fungal diseases, or nutrient imbalances causing discoloration and weak growth. Salty air, drought, and soil issues in Malibu can worsen these vulnerabilities. Undiagnosed problems during trimming can spread via contaminated tools. Always use specialists for diagnosis. If you can, we recommend that you integrate treatments like frond removal with fertilization. We generally will only trim dead/diseased parts to avoid stress to the trees.

Neighbor and Property Disputes --Be advised that trimming overhanging branches reaching into your property is allowed so long as you aren’t harming the tree. But we have seen where full cuts or removals have lead to lawsuits (e.g., $10k+ per tree for view-blocking). Property values dense coastal lots and celebrity estates tend to heighten conflicts. Wind-thrown branches from untrimmed trees cause damage claims to be filed. Always communicate first with your neighbors. Always hire pros for boundary work. California's self-help rule applies only to overhangs—don't cross property lines.

Structural Hazards in Young/Mature Trees -- Many issues such as included crotches (weak branch unions) or multiple leaders, will worsen over time if not addressed early in a tree’s life. The high winds and seismic activity in Malibu can also make unstable trees risky. Formative pruning in first 30 years can prevent costly removals later. We recommend that you schedule annual checks by certified arborists. We also follow ANSI A300 standards for cuts to promote strong form without over-thinning.
