Best Tree Services in San Carlos, CA

Yes, if the tree is protected. Under San Carlos Municipal Code Section 18.18.070 (Ordinance #1580, effective June 2022), two categories of trees are protected: Heritage trees (indigenous species like oaks, redwoods, bay laurel, madrone, and buckeye above species-specific size thresholds) and Significant trees (any non-excluded species with a trunk diameter of 11 inches or more, measured at 54 inches above natural grade). Eucalyptus trees are unprotected under the 2022 ordinance update. You must notify neighbors within 300 feet at least 14 days before removal. Contact planning@cityofsancarlos.org.

No. The 2022 Protected Tree Ordinance (#1580) explicitly excluded eucalyptus from protection. You do not need a permit to remove or prune a eucalyptus tree on your property in San Carlos, regardless of size. This is a change from some neighboring cities (like Redwood City and San Mateo) where eucalyptus trees above certain size thresholds are still protected. The city's rationale is that eucalyptus trees are not native to California and are often fire hazards.

A 24-inch box replacement tree is generally required when a protected tree is removed. The city arborist may also permit a 15-gallon tree when a 24-inch box is not suitable for the site. If replanting is not feasible on your property, the Community Development Director has discretion to allow payment of a tree replanting fee instead. Replacement trees must come from the city's Preferred Tree List. Note that the 2022 ordinance removed redwoods from the Heritage Tree Replacement List due to their high water usage and unsuitability for smaller lots.

If a protected tree poses an immediate safety risk to life or property, you can obtain oral permission from the Community Development Director for emergency removal — without going through the standard permit process. Document the emergency condition with photos and follow up with the planning department afterward. Having a certified arborist assess and document the hazard strengthens your position.

Yes. Under the 2022 ordinance, property owners must notify all neighbors within 300 feet of their property at least 14 days before tree removal or pruning of a protected tree. This applies to both removal and significant pruning (25%+ of the canopy). This notification requirement was extended from 10 to 14 days in the 2022 update, and pruning permits now require neighbor notification as well.

Yes. Protected tree removals or pruning done by PG&E as part of their vegetation management work are not subject to the city's protected tree permit process. If PG&E determines a tree is unsafe due to proximity to their infrastructure, they have authority to remove or prune it. However, if the work requires accessing the public right-of-way, PG&E does need an encroachment permit from the city's Public Works Department, which includes neighborhood notification.

Tree removal costs in San Carlos vary by size and species protection status. Small trees (20–30 ft) typically cost $1,300–$3,000, medium trees (30–50 ft) cost $3,000–$5,500, and large trees (50–80 ft) cost $5,500–$10,000. Protected or heritage trees cost more ($9,000–$16,000+) due to permit requirements, arborist review, and neighbor notification. Stump grinding adds $225–$475 per tree. The city charges modest permit fees (typically $50–$150), but the bulk of cost is labor and equipment.

Under Ordinance #1580 (effective June 2022), San Carlos protects Heritage trees and Significant trees. Heritage trees are indigenous species above species-specific thresholds: Coast Live Oak and Valley Oak at 30 inches circumference (9.5\" diameter); Blue Oak and Interior Live Oak at 24 inches circumference; Coast Redwood at 15 inches diameter; and California Bay Laurel, Madrone, and Buckeye at 30 inches circumference. Significant trees are any other non-excluded species with a trunk diameter of 11 inches or more (measured at 54 inches above natural grade). Eucalyptus trees are explicitly excluded from protection.

Ordinance #1580, effective June 2022, modernized San Carlos's protected tree ordinance. Key changes include: (1) Lowered heritage tree thresholds for coastal oaks to 30 inches circumference; (2) Excluded eucalyptus from protection entirely; (3) Extended neighbor notification from 10 to 14 days; (4) Expanded pruning permits to include pruning of 25%+ of canopy on protected trees; (5) Removed Coast Redwoods from the Heritage Tree Replacement List due to water usage concerns; and (6) Mandated use of Hortscience | Bartlett Consulting for arborist review of all permit applications.

Tree trimming costs depend on size and permit requirements. Small trees (20–30 ft) cost $250–$500, medium trees (30–50 ft) cost $500–$1,000, and large trees (50–80 ft) cost $1,000–$2,200. Heritage oak crown reduction is $2,000–$4,000. No permit is required for pruning less than 25% of the canopy, but pruning over 25% requires a permit and neighbor notification. Permit fees are modest ($50–$100), but complex work on large or protected trees increases labor costs significantly.

Tree safety inspections vary in scope and cost. A visual inspection by an ISA Certified Arborist costs $200–$325. A written assessment (required for permits) costs $325–$575. Resistograph or decay detection (often required for heritage trees) costs $550–$950. Construction site assessments (tree protection plans) cost $650–$1,150. Pre-purchase assessments for multiple trees cost $750–$1,300. San Carlos mandates Hortscience | Bartlett Consulting for all city-required arborist reviews; private consultations are also available.

Unauthorized removal of a protected tree in San Carlos can result in significant penalties. The city can impose civil fines of $500–$2,500 per tree (or more), and the Community Development Director can require replanting of a replacement tree or payment of a reforestation fee. The city also has authority to pursue enforcement action against contractors who perform unpermitted work. If you have already removed a protected tree without a permit, consult with a local arborist and contact the city's Planning Department immediately to discuss remediation options.

You have the right to trim branches that hang over your property line, but only to the property line—you cannot trim beyond it. If the tree is protected in San Carlos, you should notify your neighbor and recommend they obtain a permit from the city, as the neighbor is responsible for the permit even if you are doing the work. If the tree poses a hazard (dead limbs over your property), document the condition and contact your neighbor in writing. If they refuse to address the hazard, contact San Carlos Planning Department. Never trespass or trim a protected tree on someone else's property without their written consent and the city's permit.

Sudden Oak Death (SOD) is a fatal disease caused by the pathogen Phytophthora ramorum. It primarily affects coast live oak and tanoak trees, causing lethal twig and leaf dieback that can kill a tree in 1–5 years. SOD is present in parts of the San Francisco Bay Area, and risk is moderate in San Carlos due to the high density of coast live oaks, cooler coastal climate, and moist soil conditions. The California Oak Mortality Task Force recommends annual monitoring for coast live oak trees. Some arborists recommend preventive trunk injections of phosphite, especially for high-value heritage oaks.

The best time to prune oak trees in San Carlos is late fall through early winter (October–February), when oak wilt and other pathogens are less active. Avoid pruning in spring and summer, when bacterial wilt pathogens can spread via pruning wounds. All pruning cuts should be made close to the branch collar without leaving a stub, and pruning tools should be disinfected between trees. For heritage oaks, always hire an ISA Certified Arborist and obtain a city permit before pruning 25% or more of the canopy.

Yes. Any construction project in San Carlos that may impact protected or significant trees requires a tree protection plan prepared by an ISA Certified Arborist. The plan must include: (1) Identification and inventory of all protected trees; (2) On-site Tree Protection Zones (TPZ) marked with fencing; (3) Construction practices to avoid damage (no grading within TPZ, no soil compaction); and (4) Monitoring during construction. If protected trees are damaged or destroyed during construction, you may be required to pay significant mitigation fees or replace the tree. Contact the city's Planning Department early in your project planning.

Appraised value + mandatory replacement for Heritage Oaks (≥30″ circumference). Always obtain a permit before removing any protected tree in San Carlos. The city may also require replacement plantings at a 2:1 or 3:1 ratio.

Review required (specific timeline not stated). Plan ahead — emergency removals (storm damage, immediate hazard) can often be expedited by calling the city's planning or public works department directly.
