Do I Need a Tree Permit in Cupertino?
Cupertino protects native trees at 12 inches diameter and imposes some of the steepest heritage tree penalties in the Bay Area — $25,000–$40,000+ with mandatory 3:1 replacement. Here's the full permit process, fees, and what to watch out for.
Does my tree need a permit?
Select your tree type and measure the trunk to get an instant answer based on Cupertino's ordinance (Ordinance 14.18).
DBH = diameter measured at 4.5 feet above natural grade (DBH). Wrap a tape around the trunk and divide by 3.14.
What trees are protected in Cupertino?
Cupertino uses a multi-trunk formula for trees with multiple trunks — add the diameters of the two largest trunks to determine if the tree meets the 12-inch threshold. Heritage tree penalties ($25,000–$40,000+) with mandatory 3:1 replacement ratio make Cupertino one of the costliest cities for violations.
| Category | Protected at | Notes | Penalty |
|---|---|---|---|
| Coast Live Oak, Valley Oak | ≥12″ DBH | Most common protection trigger | $25,000–$40,000+ |
| Coast Redwood | ≥12″ DBH | Heritage review often triggered | $25,000–$40,000+ |
| California Bay Laurel | ≥12″ DBH | SOD vector species — still protected | Appraised value + 3:1 replacement |
| California Buckeye, Madrone | ≥12″ DBH | Native species protection | Appraised value + 3:1 replacement |
| Non-native trees | ≥12″ DBH | Multi-trunk formula applies | Appraised value + replacement |
| Heritage-designated | Any size | Planning Commission review required | $25,000–$40,000+ |
Not sure if your tree qualifies?
Measure first. An arborist consultation ($150–$300) is far cheaper than violation penalties. Call Planning Division at (408) 777-3308 — they can often tell you on the phone whether your tree is likely protected.
How to get a tree removal permit in Cupertino
Cupertino's permit process runs through Planning Division. Here's the step-by-step sequence:
Measure your tree
Measure trunk diameter at 4.5 feet above natural grade (DBH). For multi-trunk trees, add the two largest trunk diameters. If total is 12 inches or more and the species is native, the tree is protected.
Hire a certified arborist
An ISA Certified Arborist report is required for all protected tree removal applications. The report must document condition, reason for removal, and alternatives. Budget $300–$600.
Submit to Planning Division
File the Tree Removal Permit Application with the Planning Division at (408) 777-3308. Include the arborist report, site plan, and photos. Pay the $197 permit fee.
City review and inspection
A city arborist reviews the application. Heritage trees require Planning Commission review. Standard processing takes 4–6 weeks. Heritage trees may take longer.
Receive permit and schedule work
Once approved, hire a licensed tree service (CSLB C-61/D-49). The permit must be on-site during removal. Replacement planting at 3:1 ratio is required for heritage trees.
What happens if you remove a tree without a permit?
$25,000–$40,000+ for heritage trees
Cupertino imposes some of the Bay Area's steepest penalties for unauthorized tree removal. Heritage tree violations carry fines of $25,000–$40,000+ per tree, mandatory 3:1 replacement planting, and potential misdemeanor charges. Standard protected tree violations carry the tree's appraised value plus replacement costs. The Planning Division actively enforces violations.
A permit costs $197 and takes 4–6 wks. The penalties for skipping it are orders of magnitude higher. There's no scenario where unpermitted removal saves money.

Frequently asked questions
Does pruning require a permit in Cupertino?
Pruning that removes less than 25% of the canopy and follows ISA standards does not require a permit. Crown reduction, topping, or structural changes on protected trees require city approval.
What if the tree is dead or hazardous?
Dead or hazardous trees can be removed with expedited approval, but you still need to notify Planning Division before proceeding. Document the hazard thoroughly. Emergency removals should be reported within 10 days.
What is the multi-trunk formula?
For trees with multiple trunks, Cupertino adds the diameters of the two largest trunks to determine if the tree meets the 12-inch DBH threshold. For example, a tree with trunks of 7 inches and 6 inches (total 13 inches) would be considered protected.
