Tree Removal: When You Need a Permit and When You Don't

It seems like it should be straightforward. The tree is on your property, so you can cut it down whenever you want. But in many cities, that assumption will get you a fine that can run into the thousands of dollars. Tree protection ordinances exist in cities across the country, and they govern when you need a permit, what trees are protected, and what happens if you remove one without authorization.

Heritage and protected tree laws

Many cities maintain lists of protected tree species or designate individual trees as heritage trees based on age, size, or historical significance. In cities like Oakland and Pasadena, native oaks above a certain trunk diameter are automatically protected. San Francisco protects any tree on city-maintained property and has a separate process for privately owned significant trees. Phoenix protects certain native desert trees including palo verde and ironwood. Protected status means you cannot remove the tree without a permit, and the permit may come with conditions such as replacement plantings or mitigation fees. In some cases, permits for protected tree removal are denied outright unless the tree poses an imminent safety hazard.

Diameter thresholds trigger permit requirements

Even for trees that are not on a protected species list, many cities require a permit for removing any tree above a certain trunk diameter. The threshold varies, but common standards are 6 inches, 8 inches, or 12 inches in diameter measured at 4.5 feet above ground level, which arborists call diameter at breast height. If the tree on your property exceeds the threshold, you need a permit before you cut. This applies whether you hire a contractor or do the work yourself. The permit process typically involves an application, a fee, and sometimes a site visit from the city arborist or planning department.

Dead tree removal usually does not require a permit

Most cities exempt dead, dying, or imminently hazardous trees from the permitting process, but "dead" and "hazardous" have specific definitions. A tree with a few dead branches is not a dead tree. A tree that is leaning slightly is not necessarily hazardous. Many cities require documentation, such as a report from a certified arborist, confirming that the tree is dead or poses an immediate danger before the exemption applies. If the city disagrees with your assessment after the tree is already removed, you may be cited retroactively. When in doubt, get the arborist report first.

Emergency removal after storms

When a tree falls during a storm or is severely damaged and poses an immediate risk to life or property, most cities allow emergency removal without a prior permit. However, you are typically required to notify the city within a set timeframe, usually 48 to 72 hours, and may need to provide documentation including photos of the damage and the arborist's assessment. The emergency exemption covers the immediate hazard. If the tree is damaged but still standing and not in imminent danger of falling, the standard permit process usually applies.

Replacement requirements add cost

Cities with tree protection ordinances frequently require replacement plantings when a permitted tree is removed. The ratio varies. Some cities require one-for-one replacement while others require two or even three new trees for every one removed. The replacement trees must meet minimum size standards, typically a 15-gallon or 24-inch box specimen, and must be maintained for a set period to ensure survival. If your property does not have space for replacement trees, some cities allow you to pay an in-lieu fee into a city tree planting fund. These fees can range from several hundred to several thousand dollars per tree.

Penalties for unauthorized removal

Removing a protected tree without a permit is one of the more heavily penalized code violations in cities that take tree protection seriously. Fines in cities like Oakland and San Francisco can reach $10,000 or more per tree, and the city may require you to plant replacement trees at a higher ratio than would have been required with a permit. In extreme cases, cities have sought restitution based on the appraised value of the removed tree, which for large mature specimens can be calculated in the tens of thousands of dollars based on arboricultural valuation methods.

How to check before you cut

The process is simple. Contact your city's planning department or urban forestry division before removing any tree. Describe the tree's species if you know it, its approximate trunk diameter, and its location on your property. The city will tell you whether a permit is required, what the process involves, and what conditions apply. This five-minute phone call or email can save you thousands of dollars in fines and replacement costs.
