Tree Service in Agoura Hills, CA
Since December 2025, Agoura Hills protects its sycamores as well as its oaks. From ranch lots to hillside homes, our tree service in Agoura Hills checks those rules before we trim or remove a tree.
Tree care in Agoura Hills
Three native trees, one permit system
Since December 2025, Agoura Hills protects sycamores and black walnuts as well as its oaks. Ordinance 25-482 covers any oak, California sycamore or Southern California black walnut that is 6 inches across at 4.5 feet up, and every scrub oak at any size. A tree 48 inches across is a landmark tree. The root zone runs 5 feet past the drip line and never less than 15 feet from the trunk. Small pruning cuts count as routine care, but topping and lion tailing are banned in all cases. For questions, the city's Oak Tree Consultant is at City Hall on Tuesdays.
In Agoura Hills, the tape measure comes out before the saw does.
The list
Agoura Hills oak pruning, palm trims before fire season, and removals
Supreme Tree Experts prunes oaks, removes trees and trims palms in Agoura Hills, where 6-inch oaks are protected. With Woolsey Fire embers in mind, Agoura Hills owners clear dead palm fronds with Supreme Tree Experts.
Tree Removal
We take out dead and failing trees in Agoura Hills after checking species and trunk size. Since December 2025, oaks and California sycamores 6 inches or more across at 4.5 feet need a Protected Tree Permit. Scrub oaks need one at any size, and you apply for it.
Tree Trimming & Pruning
Our crews prune protected oaks within the city's routine-care limits whenever the job allows. Branches under 3 inches, taking no more than 20% of the crown, need no permit here. Larger cuts need a General Tree Permit, and the city reviews it within 30 days.
Stump Grinding & Stump Removal
We grind the stump of a removed non-native tree well below grade and clear the chips. If you replant that spot with a new oak, you can register it with the city. Registered trees stay outside the permit rules later on.
Palm Tree Trimming & Skinning
We strip dead fronds and seed stalks from palms near Agoura Hills homes before the dry fall winds. The whole city was under evacuation during the 2018 Woolsey Fire. Skinning pulls the old frond stubs from the trunk, leaving less dry fuel beside the house.
Emergency Tree Service
Our 24/7 crews respond when wind or fire drops a tree on a home or across a drive. In an emergency, fire or police can order a dangerous protected tree down and tell the city after. We then cut it up and haul the wood away.
Tree Maintenance
We check protected oaks and sycamores for deadwood, pests and root trouble once a year. Valley oaks and sycamores drop their leaves in winter, so a bare tree may not be dead. Only the city's Tree Consultant can confirm that.
Tree Height Reduction
We lower tall crowns here with reduction cuts back to a strong side limb. Agoura Hills bans topping in every case, even as routine care. Proper cuts keep the natural form and avoid a flush of weak sprouts.
Estate Tree Care
We manage every tree on ranch lots and large hillside parcels here with a plan that runs year to year. A protected tree 48 inches across counts as a landmark tree under city code. Those giants get their own notes, from deadwood to root zone.
Tree Shaping & Shrub Shearing
Our crews shear hedges and shape shrubs to a clean line, and thin small trees evenly through the crown. City code bans lion tailing, which strips inner branches and leaves foliage only at the tips. Even thinning keeps the plant full and strong.
Landscaping
We design beds, lawns and irrigation for Agoura Hills yards that share space with native oaks. The protected root zone runs 5 feet past the drip line and never less than 15 feet from the trunk. We keep new planting and watering outside it.
Hardscape
We plan patios, decks, pool edges and garden walls around the trees you want to keep. Building one near a protected oak or sycamore can need a city permit first. We tell you what the rule allows before any digging starts.

From root zones to reach: how we work on Agoura Hills oaks
Tree work goes wrong when it is rushed or under-equipped. We run our own 75-foot boom trucks, lift trucks, chippers and stump grinders, and every crew works under an ISA Certified Arborist — so the job gets done right the first time.
We hold California license #1002853 for both landscaping and tree and palm work, we are bonded, we carry general liability and every employee is on workers’ compensation.
ISA Certified Arborist
An arborist can tell a scrub oak from a shrub, and a young sycamore from a big one. In Agoura Hills, that decides whether you need a permit.
Licensed, Bonded & Insured
Pruning on protected trees here has to meet ANSI A300 and ISA practice. Our crews work under state license #1002853 for tree service (C-61/D-49) and landscaping (C-27), bonded and insured.
Southern California Since 1985
Agoura Hills became a city in 1982. Our family business opened three years later, in 1985, and has cared for Southern California trees ever since.
Our Own Equipment
Our own 75-foot boom trucks reach into an oak from outside its root zone, so heavy wheels stay off the roots.

Before you book in Agoura Hills
6 questions worth having answered before you book tree work in Agoura Hills. If yours is not here, call 877-787-7363 and ask.
Any oak, California sycamore or Southern California black walnut 6 inches or more across, plus every scrub oak. Measure the trunk 4.5 feet above the ground. For a tree with several stems, the city combines them with a set formula. Removing or damaging one needs a Protected Tree Permit from the Director or the Planning Commission.
Light pruning, yes. Cutting branches under 3 inches across, without losing more than 20% of the crown, counts as routine care, and so does removing dead wood. Anything more needs a General Tree Permit, and topping or lion tailing is never allowed. If the pruner is not on the city's endorsed list, the Tree Consultant inspects first.
You can register it with the city. Owners who choose to plant new protected trees may put them on file, and registered trees are not bound by the permit rules. This does not apply to trees planted to replace ones removed under a permit. It is the city's way of rewarding owners who add native canopy.
The whole city was ordered out. The fire started on November 8, 2018, and by November 10 all of Agoura Hills was under evacuation. One person died in a home on Lobo Canyon Road. In January 2025, the Kenneth Fire brought evacuation warnings again. Dead wood and dry fronds near the house are the first things to clear.
Yes — $600 for tree services, wherever the job is. Permit steps, photos and root-zone care around protected oaks shape most jobs here.
Yes, 24/7. Santa Ana winds drove the Woolsey Fire through this city in 2018, and dry wind can drop big limbs without warning. Call 877-787-7363.
