Do You Need a Permit to Cut Down a Tree in California?

In most California cities and counties, you need a permit to cut down a tree in California if it is a “protected” tree under your local ordinance, which usually means a native species, a tree above a set trunk diameter, a designated heritage tree, or any tree in the public right-of-way. There is no single statewide permit; the rules are written and enforced by your city or, for unincorporated land, your county. State laws on oak woodlands, nesting birds, and wildfire defensible space sit on top of whatever local rule applies to you.

Which Trees Are Protected

Local ordinances decide what counts as protected using some combination of trunk size, species, and location. Not every tree on your lot triggers a permit, but once a tree meets the local criteria, removal without approval is a code violation.

Trunk size is usually measured by diameter at breast height, 4.5 feet above the ground. Some cities protect any tree above a general threshold (commonly 8 to 12 inches), while native species often have a much lower bar. Los Angeles protects native oaks, sycamores, California bay, and Southern California black walnut starting at just 4 inches in cumulative trunk diameter.¹

Many cities also designate individual “heritage trees” based on age, size, or historical significance. San José makes it illegal to prune or remove a heritage tree without consulting the city arborist and obtaining a permit.² Heritage definitions vary; one city uses trunk circumference, another uses canopy spread or species.

Street trees and any tree in the public right-of-way almost always need a municipal permit regardless of species or size. Even unauthorized pruning of a street tree draws penalties in most California cities.

Who Issues the Permit and What You File

If you are in an incorporated city, the permit comes from the planning or community development department. If you are in an unincorporated county area, it comes from the county planning or public works office. Call that office first and ask whether your specific tree is protected before spending money on anything else.

Most jurisdictions ask for the same core package:

An arborist report from a certified arborist, documenting the tree’s species, size, health, and the reason for removal. These typically run $75 to $450.
A site plan showing the tree’s location relative to structures, property lines, and other trees.
Clear photographs of the tree from multiple angles.
A non-refundable filing fee set by the jurisdiction.
A replacement planting plan. Many cities require at least two new trees for every one removed, in approved species and minimum sizes.

The review timeline is longer than people expect. Some cities post a public notice period for neighbors to comment, and contested removals can go before a planning commission. Figure 90 to 120 days from application to final decision, and plan any construction schedule around that.

When You Don’t Need a Permit

Even protected trees come with exemptions, though the exact list depends on the ordinance:

Dead trees are generally exempt, but the city often wants photos or an inspector’s confirmation that the tree is actually dead before you cut.
Emergency hazards, such as a cracked trunk leaning after a storm, can be removed immediately. Expect to notify the city and file an after-the-fact report with documentation.
Cultivated fruit and nut trees are commonly excluded from protection.
Some cities exempt non-native invasive species, though which species qualify varies.

Document everything even when an exemption clearly applies. Take photos before and during the work, keep any written arborist assessment, and save your communication with the city. If a dispute surfaces later, that paper trail is your defense.

Wildfire Defensible Space Changes the Rule

If your property sits in a state responsibility area or designated fire hazard zone, the obligation can flip. California law requires owners to maintain 100 feet of defensible space around any structure, which means clearing or thinning vegetation rather than preserving it.³ Cal Fire administers the standards for the three zones radiating out from the building.⁴

The law does not require clear-cutting. Individual, well-pruned trees that will not rapidly carry fire to or from a structure can remain.³ Defensible space obligations generally override local tree protection ordinances in fire hazard zones, but some cities still want notice before you remove a protected tree for fire safety. Check with your local fire marshal or planning department first.

Nesting Birds Can Stop a Permitted Cut

A valid city permit does not override state wildlife law. California law makes it illegal to destroy the nest or eggs of any bird,⁵ with a separate provision extending protection to migratory birds covered by the federal Migratory Bird Treaty Act.⁶

Nesting season in most of California runs roughly February through August. If removal is planned in those months, hire a qualified biologist to survey the tree before work starts. If an active nest with eggs or chicks turns up, you wait until the young have fledged. Destroying an occupied nest is a criminal violation, not just a code infraction, and planning department approval is no defense.

Oak Woodlands and Development Projects

If the removal is tied to a construction project rather than taking out a single backyard tree, a separate state process kicks in. Counties must evaluate whether a project will convert oak woodlands in a way that significantly harms the environment. A protected “oak” is any native tree in the genus Quercus with a trunk at least 5 inches in diameter at breast height.⁷

When a significant impact is found, the county must require mitigation: conservation easements, replacement planting, contributions to the Oak Woodlands Conservation Fund, or other measures. Replacement planting alone can satisfy no more than half of the total mitigation requirement.⁷ This mostly affects development in unincorporated county areas.

Hiring a Licensed Tree Contractor

California requires tree service professionals to hold a C-49 Tree and Palm license from the Contractors State License Board. The classification covers planting, maintaining, pruning, removing, and grinding stumps of trees and palms.⁸

A contractor license is not required when the total job cost — labor, materials, and everything else combined — falls below $1,000.⁹ Most mature tree removals clear that threshold easily, so in practice you need a licensed contractor. Operating without one is a misdemeanor carrying fines up to $5,000 for the contractor.

Before hiring, verify the license on the CSLB website and ask for proof of general liability insurance and workers’ compensation coverage. All C-49 contractors with employees must carry workers’ comp. If an uninsured worker is hurt on your property, you can be exposed for their medical bills and lost wages.

What Happens If You Skip the Permit

The consequences stack up. San José imposes fines up to $30,000 per heritage tree removed without a permit.² Other cities calculate penalties based on trunk diameter or appraised value. On top of the fine, replacement planting is usually required at an elevated ratio of three to five new trees per illegally removed tree, with monitoring that can run for years.

Some cities add consequences that reach beyond the tree. Los Angeles can withhold building permits on the property for up to ten years after an unauthorized removal of a protected tree or shrub.¹⁰ If the removal was meant to clear space for construction, that alone can kill the project. Unauthorized removal can also be charged as a misdemeanor under local codes.

Cutting Down a Neighbor’s Tree

Removing or significantly damaging a tree on someone else’s property triggers civil liability well beyond any municipal fine. California law lets a property owner recover three times their actual damages for wrongful injury to their trees. If the trespass was an honest mistake about a property line, the multiplier drops to double damages.¹¹ A separate statute also authorizes treble damages when someone cuts or removes trees from another person’s land without legal authority.¹²

Mature trees, especially native oaks, can be appraised at tens of thousands of dollars. Triple that number, add attorney’s fees, and a single tree cut in a boundary dispute can produce a six-figure judgment. The statute of limitations is five years, so the neighbor does not need to catch you in the act.¹¹
