Hillsborough Tree Service

Hillsborough is known for its beautiful estate properties, tree-lined streets, and mature urban canopy that help define the town’s natural beauty, privacy, and prestigious character. Trees throughout Hillsborough play a vital role in preserving the community’s scenic landscape while providing important environmental and property benefits. Mature trees create shade, improve air quality, reduce noise pollution, support local wildlife habitats, increase property value, and contribute to the peaceful atmosphere that makes Hillsborough one of the most desirable residential communities on the Peninsula.

The area is home to several important native and ornamental tree species, including Coast Live Oaks, Valley Oaks, Coast Redwoods, California Bay Laurels, and mature Cedar and Pine trees commonly found throughout estate properties. Coast Live Oaks are especially valued for their strong structure, longevity, and broad canopies that provide excellent shade and environmental benefits. Coast Redwoods, among the tallest trees in the world, help support local ecosystems, improve air quality, and create the iconic natural beauty associated with the Peninsula and Bay Area landscapes.

Proper tree care and maintenance are essential to protecting the health, structure, safety, and longevity of Hillsborough’s trees. Without routine pruning, monitoring, and preventative maintenance, trees can become overgrown, structurally weak, diseased, or hazardous during storms and high winds. Responsible tree care helps reduce safety risks, protect homes and surrounding property, improve tree health, and preserve the long-term beauty and environmental value of Hillsborough’s urban forest and estate landscapes.

We proudly follow ANSI arboricultural standards, proper pruning techniques, and local tree ordinances to ensure every project is completed safely, responsibly, and professionally.

Hillsborough has strict tree protection ordinances designed to preserve the town’s mature tree canopy, estate landscapes, and natural beauty that define the character of the community. Trees throughout Hillsborough provide significant environmental, aesthetic, and property value benefits, which is why the town carefully regulates tree removal and major pruning activities. Proper tree care and ordinance compliance are essential because unauthorized removal or improper trimming of protected trees can lead to substantial penalties, hazardous conditions, and long-term damage to valuable trees.

In 2023, Hillsborough updated its Tree Protection Ordinance to strengthen protections for mature trees throughout the town. Under the current ordinance, all tree species measuring 18 inches or greater in diameter, measured 4 feet 6 inches above grade (diameter standard height), are considered protected trees and may require permits before removal or major pruning work can take place. Heritage trees receive even greater protection and are generally defined as trees measuring 50 inches or greater in circumference.

Protected species commonly found throughout Hillsborough include:

• Coast Live Oaks

• Valley Oaks

• Coast Redwoods

• California Bay Laurels

• Mature Cedar and Pine trees

• Other large native and ornamental trees meeting protected size requirements

Hillsborough also regulates excessive pruning and harmful trimming practices that may negatively impact tree health or structural integrity. Improper pruning methods such as topping, excessive canopy reduction, lion’s tailing, and improper branch removal can weaken trees, increase disease risk, create hazardous conditions, and permanently damage the natural beauty and stability of the tree. In many cases, pruning beyond 25% of the canopy may require town review or permitting. Proper tree trimming should always follow ANSI A300 pruning standards and approved arboricultural practices to preserve tree health, safety, and long-term structural stability.

Tree removal applications in Hillsborough often require:

• Arborist reports

• Site plans

• Neighbor notifications

• Permit review and approval

• Replacement tree requirements in certain situations

Additional review may also be required when tree removal is associated with construction, grading, or development projects. Hillsborough can impose significant penalties for unauthorized tree removal or damage, including fines based on trunk diameter or appraised tree value.

At JJI Tree Service, we are experienced in working with Hillsborough tree ordinances, permit requirements, protected tree regulations, and proper pruning standards. Our knowledgeable arborists and tree care specialists can help homeowners, estate managers, and contractors understand local tree regulations and assist throughout the permit application and approval process when required. We help ensure all tree trimming, pruning, and removal projects are completed safely, professionally, and in full compliance with Hillsborough municipal regulations and arboricultural standards.
