Tree Service in Simi Valley, CA
Most yard trees in Simi Valley are yours to decide on, but native oaks are protected in every yard. We check that rule first on each call for tree service in Simi Valley, then trim or remove.
Tree care in Simi Valley
A valley ringed by hills and fire country
In Simi Valley, the oak in your yard is protected, but most other yard trees are not. A native oak counts once its trunk is 5 inches across, measured 4½ feet up. Other trees in single-family yards can come out without a permit. The city fills a valley with the Santa Susana Mountains to the north and the Simi Hills to the east and south. Those hills put it in a high-risk area for wildfire, and in 2003 the Simi Fire burned about 108,000 acres. The name comes from the Chumash word Shimiyi, for thin, stringy clouds.
One oak can change the whole plan for a Simi Valley yard.
Services
Only the oaks need a permit: Simi Valley removals, pruning and palms
Supreme Tree Experts removes yard trees, measures oaks and clears palms in Simi Valley, where 5-inch oaks are protected. Most yard trees need no permit but oaks do, and Simi Valley owners sort that out with Supreme Tree Experts.
Tree Removal
We take down yard trees across Simi Valley, and most species in a single-family yard need no city permit. A native oak is different once its trunk hits 5 inches, measured 4½ feet up. We measure every oak first and tell you what the city allows.
Tree Trimming & Pruning
Our crews prune yard trees back to strong side branches, never topping them. Street trees belong to the city, whose own crews prune and replant them. We keep our cuts to the trees on your lot and haul off every limb.
Stump Grinding & Stump Removal
Grinding takes each stump below grade so the spot can be replanted or covered. After a permitted oak removal, the city requires new specimen trees of equal total value on the same property. A ground-out stump clears room for them close to where the old oak stood.
Palm Tree Trimming & Skinning
Our lift truck lets us trim dead fronds and skin old frond bases without spikes in the trunk. Hills to the north, east and south put this valley in a high-risk wildfire area. Dry skirts of fronds are fuel, so we clear them before fire season.
Emergency Tree Service
We answer calls 24/7 when a tree or big limb comes down on a Simi Valley home, drive or fence. Wind off the surrounding hills can drop trees here with little notice. The crew makes the site safe first, then cuts and hauls the wood.
Tree Maintenance
We inspect and prune yard trees on a set cycle, catching dead wood, weak forks and pests early. On apartment, commercial or vacant land here, any mature tree needs a permit to come out. Regular care keeps those trees sound, so removal rarely comes up.
Tree Height Reduction
Our crews bring down tall crowns with reduction cuts back to side limbs, not by topping. Many homes here back onto slopes, where a tall tree leans its weight toward the house. We cut the crown down to a size the lot can carry.
Estate Tree Care
Larger Simi Valley properties get one care plan that covers every tree on the lot. To remove a protected oak, the owner must show a reason from the city's list, such as disease. Our yearly notes track each oak, which helps if a tree report is needed.
Tree Shaping & Shrub Shearing
Our shears keep hedges to a neat, even line, with shrubs shaped often enough to stay full. The city sets height and location limits for fences, walls and hedges. We keep your hedge inside those limits and bag every clipping.
Landscaping
New planting we design suits this hill-ringed valley and keeps beds clear of oak trunks. Any planting in the street right-of-way must meet Public Works Standards. We keep new work on your side of the curb, with drip watering where it counts.
Hardscape
We build patios, paths and low walls that suit Simi Valley yards and work around the trees already there. Damage to pavement is one reason the city accepts for removing a protected oak. We set new paving well clear of big roots so it never comes to that.

The questions worth asking any Simi Valley tree company
6 of them, answered here for Simi Valley. If yours is not here, call 877-787-7363 and ask.
Only if it is a native oak, or the lot is not a single-family home. A native oak 5 inches or more across needs a Tree Removal Permit. Other species in a single-family yard do not. On apartment, commercial, industrial or vacant land, any mature tree needs a permit. Call the Planning Division at (805) 583-6769.
The owner must show a reason from the city's list. Examples: the tree is diseased or may collapse, blocks utilities or a home addition, damages pavement or buildings, or the lot is crowded with mature trees. A tree report may be needed, and the city may ask for the tree to be moved instead of cut down.
Yes, after a permitted removal. One or more specimen trees with a total value equal to the removed tree must be planted on the same property. That value depends on the size, species and health of the tree that came out.
The city. Mature trees in the public right-of-way may only be removed by the Public Works Department. City arborists and contract crews prune, remove, replant and handle emergencies. All work in the street right-of-way must meet Public Works Standards. Report a problem at (805) 583-6400 or publicworks@simivalley.org.
Yes — $600 for tree services, wherever the job is. Whether an oak permit is needed, and how close the tree stands to the house, shape most prices here.
