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).

Permit required. Contact Planning Division at (408) 777-3308 before scheduling any work.

Measure diameter at 4.5 feet above natural grade. Single-trunk threshold: 12". Multi-trunk: sum ALL trunks, threshold 24". Wrap a tape around the trunk and divide by 3.14.

What trees are protected in Cupertino?

Cupertino protects 11 specific specimen species under Ordinance 14.18. For multi-trunk trees, sum the diameters of ALL trunks — the aggregate threshold is 24 inches (not 12). Redwood, madrone, eucalyptus, and other non-listed species are NOT protected. Violations are infractions ($100/$200/$500) plus replacement per Table A or ISA-appraised in-lieu.

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:

1

Measure your tree

Measure trunk diameter at 4.5 feet above natural grade. For multi-trunk trees, sum ALL trunk diameters — the aggregate threshold is 24 inches. Single-trunk threshold is 12 inches. Confirm the species is one of the 11 protected specimen species (redwood and madrone are NOT protected).

2

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.

3

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. Fee: $465 first tree + $183 each additional (no arborist review), or $851/$274 with city arborist review.

4

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.

5

Receive permit and schedule work

Once approved, hire a licensed tree service (CSLB C-49). The permit must be on-site during removal. Replacement per Table A: one or two 24-inch-box trees for specimen species, 48-inch-box for heritage trees.

What happens if you remove a tree without a permit?

Infraction fines + replacement + $6,055 retroactive fee

Unauthorized removal is an infraction under Ch. 1.12: $100 first offense, $200 second, $500 each subsequent. You must also replace trees per Table A (one or two 24-inch-box for specimen, 48-inch-box for heritage) or pay ISA-appraised value in-lieu (14.18.220, .160). The retroactive permit fee is $6,055 per tree — more than 13 times the standard $465 fee. The Planning Division actively enforces violations.

A permit costs $465 and takes 4–6 weeks. A retroactive permit after unpermitted removal costs $6,055 per tree plus infraction fines and mandatory replacement. There is no scenario where skipping the permit 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 trees require a Director determination BEFORE removal — you cannot remove first and ask later. Emergency removal is allowed only on order of the Director, sheriff, or fire department. A no-fee retroactive permit must be filed within 5 working days (14.18.150(B)). Document the hazard thoroughly with photos.

What is the multi-trunk formula?
For trees with multiple trunks, Cupertino sums the diameters of ALL trunks (not just the two largest). The multi-trunk aggregate threshold is 24 inches — double the single-trunk threshold of 12 inches (14.18.020). For example, a tree with three trunks of 9, 8, and 8 inches (total 25 inches) would be protected.
