Best Tree Services in Woodside, CA

Yes — Woodside requires a Tree Destruction Permit for any Significant Tree. The size threshold depends on the species: slower-growing natives like madrone, blue oak, and buckeye are protected at just 24 inches circumference (7.6 inches diameter); faster-growing natives like coast live oak, redwood, and bay laurel at 30 inches circumference (9.5 inches diameter); and all other species at 36 inches circumference (11.5 inches diameter). Measurements are taken at 48 inches above mean natural grade. Contact the Town at (650) 851-6790.

Eucalyptus, Acacia, and Monterey Pine trees are fee-exempt — you won't be charged permit fees for removing them. This reflects their status as non-native species and, in the case of Monterey Pine, their susceptibility to pine pitch canker. Trees removed under the Town's Defensible Space and Home Hardening Program are also fee-exempt, which is particularly relevant for Woodside properties in wildfire-prone areas.

Woodside takes unauthorized tree removal extremely seriously. A prominent 2016 case resulted in a $212,500 fine for removing 22 mature oaks, bay laurels, and madrone trees without a permit on a 3-acre property. The case drew significant community attention and reinforced that Woodside — named for its forested character — will aggressively enforce its tree protection ordinance. Always obtain a Tree Destruction Permit before any work.

Most Peninsula cities measure trunk diameter at 54 inches above grade (DBH — Diameter at Breast Height), which is the ISA and forestry standard. Woodside measures at 48 inches above mean natural grade. This lower measurement point typically captures a slightly larger trunk diameter (trees taper as they go up), meaning some trees that would fall below the protection threshold at 54 inches may qualify for protection in Woodside. It's a subtle difference, but it matters for borderline cases.

It depends on the species. For Madrone, Blue Oak, and Buckeye trees, the measurement is the sum of the circumference of all trunks that have developed by 48 inches above grade. For California Bay Laurel, only the largest trunk is measured. For all other multi-trunk species, consult with the Town's planning staff — these details matter because many Woodside oaks and madrones develop multiple trunks naturally.

Tree removal costs in Woodside range from $1,800–$4,000 for small trees (under 25 feet) to $15,000–$25,000+ for heritage or protected specimens (80+ feet). Medium trees (25–50 feet) typically cost $4,000–$8,000, and large trees (50–80 feet) cost $8,000–$15,000. Stump grinding adds $275–$600 per stump. Costs depend on site access, complexity, and whether the tree is protected under Woodside's three-tier system.

Woodside protects three categories of trees based on growth rate, all measured at 48 inches above mean natural grade: (1) slower-growing natives (madrone, blue oak, buckeye, alder, big leaf maple, tan bark oak, Fremont cottonwood) at 24 inches circumference (7.6 inches diameter); (2) faster-growing natives (coast live oak, coast redwood, bay laurel, Douglas fir, valley oak, black oak, western sycamore) at 30 inches circumference (9.5 inches diameter); (3) all other species at 36 inches circumference (11.5 inches diameter). Trees below these thresholds are not protected. Fee-exempt species (eucalyptus, acacia, Monterey pine) still require notifying the Town but don't need permit fees.

Woodside calls its tree removal permit a "Tree Destruction Permit" — the terminology reflects how seriously the Town takes tree protection. Most other Peninsula cities use terms like "Tree Removal Permit" or "Protected Tree Removal Permit." Woodside's "Destruction Permit" language signals that the Town treats unauthorized removal as a severe violation. The name matters: a contractor unfamiliar with Woodside's specific terminology likely hasn't worked in the community before and may not understand the three-tier system or enforcement severity.

Tree trimming costs in Woodside range from $300–$600 for small trees to $2,500–$5,000+ for heritage oaks and redwoods on estate properties. Standard pruning for one or two small trees costs $300–$600; medium-canopy structural pruning runs $600–$1,200; large tree crown reduction ranges $1,200–$2,500; and heritage oak or redwood work costs $2,500–$5,000+. Woodside's rural estates with tall mature specimens and difficult slope access often increase costs.

Tree safety inspections in Woodside range from $250–$400 for a visual assessment to $1,200–$2,500 for a full-property tree inventory. Written arborist reports cost $400–$700; resistograph decay testing ranges $650–$1,100; construction tree protection plans cost $800–$1,400; and fire zone defensible space assessments run $600–$1,000. An ISA Certified Arborist should conduct formal inspections for permit applications, construction projects, or liability documentation.

Unauthorized tree removal in Woodside carries severe penalties: up to $100,000 per tree. A prominent 2016 case involved a $212,500 fine for removing 22 mature oaks, bay laurels, and madrone trees without permits. Woodside aggressively enforces its ordinance because the Town's identity is built on its forested character. Always obtain a Tree Destruction Permit before removing any tree that meets Woodside's protection thresholds.

You can trim branches that overhang your property, but only to the boundary line and only if the trimming does not damage the tree's health or violate Woodside's tree protection ordinance. If the tree is protected (meets the size threshold under the three-tier system), removing it — even if it's on your neighbor's property — requires a Tree Destruction Permit. Before trimming, communicate with your neighbor and consider consulting an ISA Certified Arborist.

Sudden Oak Death (SOD) is a tree disease caused by Phytophthora ramorum that kills coast live oaks and tan oaks. The pathogen is present throughout the Peninsula, particularly in Woodside's Kings Mountain area, which combines high-density coast live oak and redwood forests with bay laurel (the primary vector). SOD spreads via rain splash from infected bay laurel leaves. Preventive phosphonate bark applications, applied annually in late summer or early fall before the rainy season, are the most effective defense.

The best time to prune oak trees in Woodside is late spring through early summer (June–August), after the trees have leafed out but before the fall rains begin. This timing minimizes the risk of oak wilt disease transmission and allows the tree to heal before the wet season. Avoid pruning during the rainy season (November–May) when fungal diseases spread easily. Never top oaks — the practice is harmful and creates serious liability.

Yes. Any construction near protected trees — including ADUs, additions, or remodels — requires a tree protection plan prepared by an ISA Certified Arborist. Woodside's Planning Department requires detailed documentation showing how the project will avoid damage to tree roots, maintain minimum setbacks, and protect the tree during construction. The plan typically costs $800–$1,400 but is mandatory for any permitted work near protected trees.

Yes. Woodside offers fee waivers through the Defensible Space & Home Hardening Program for trees removed or pruned as part of fire safety clearing. The Town recognizes that WUI properties in Kings Mountain, Canada Road, and Mountain Home fire zones need defensible space compliance, and the program removes cost barriers. Defensible space work typically costs $1,500–$6,000 for initial clearing and $1,800–$3,500 annually for maintenance.
