The Short Version
Berkeley regulates tree removal and significant pruning through multiple ordinances. Street trees (in the public right-of-way) are managed by the City of Berkeley Public Works Department under BMC Chapter 12.44, and property owners may not trim or remove street trees without city authorization. Private trees with trunk diameters of 18 inches or more (Coast Live Oaks at 6 inches or more) are protected under the city's landmark and heritage tree policies, requiring permits before removal. The city strongly encourages tree preservation and replacement planting.
Full Breakdown
Berkeley's tree regulations reflect the city's strong environmental ethos and urban forest management priorities. Multiple code sections govern different categories of trees.
Street trees — those planted in the public right-of-way between the curb and sidewalk or in medians — are under the jurisdiction of the City of Berkeley Public Works Department (BMC Chapter 12.44). Property owners are prohibited from trimming, removing, or damaging street trees without prior written authorization from Public Works. The city maintains a street tree inventory and schedules routine maintenance. Residents may request street tree trimming by contacting Public Works at (510) 981-6620.
For private property, Berkeley protects significant trees through its planning and environmental review processes. Trees with trunk diameters of 18 inches or more measured at 4.5 feet above grade (diameter at breast height, or DBH) generally require a permit before removal. Coast Live Oaks (Quercus agrifolia) receive enhanced protection with a lower 6-inch DBH threshold, reflecting their ecological significance in the East Bay hills ecosystem.
Removal permits are reviewed by the City of Berkeley Planning Department, which evaluates the tree's health, structural condition, species significance, and the impact of removal on the surrounding environment. Approved removals typically require replacement planting at a ratio determined by the reviewing authority, often two or more replacement trees per removed tree.
In the Hillside Fire Zone, the Berkeley Fire Department may require or approve tree trimming and removal as part of defensible space compliance. Conflicts between fire safety requirements and tree preservation policies are resolved on a case-by-case basis with input from both Fire Prevention and Planning staff.
Emergency removal of a hazardous tree that poses imminent danger to life or property is permitted without prior authorization, but the property owner must notify the city within five business days and provide documentation of the emergency condition.
What Happens If You Violate This?
Unauthorized removal of a protected private tree may result in administrative penalties of $500 to $10,000 depending on the tree's size, species, and ecological value. Unauthorized trimming or removal of a street tree is a misdemeanor under BMC Chapter 12.44, carrying fines up to $1,000 and potential requirement to plant replacement trees at the violator's expense. The city may also require payment of the appraised value of the removed tree, which for large mature specimens can reach tens of thousands of dollars.
