Do I Need a Tree Permit in Mountain View?

What trees are protected in Mountain View?
Mountain View's 12-inch circumference threshold for oaks, redwoods, and cedars is the lowest on the Peninsula — meaning relatively young trees of these species (sometimes just 5–8 years old) are protected. All other species are protected at 48 inches circumference (approximately 15 inches diameter). The City Arborist has review authority over every heritage tree removal request, and the city publishes a Tree Technical Manual (2022) for residents.
| Category | Protected at | Notes | Penalty |
|---|---|---|---|
| Oaks (Quercus spp.) | ≥12″ circumference | approximately 4″ diameter — very low threshold | $5,000–$15,000+ |
| Coast Redwood | ≥12″ circumference | approximately 4″ diameter — young trees protected | $5,000–$15,000+ |
| Cedars (Cedrus spp.) | ≥12″ circumference | approximately 4″ diameter | $5,000–$15,000+ |
| All other heritage trees | ≥48″ circumference | approximately 15″ diameter at 54″ above grade | Appraised value + restoration |
| Street trees | Any size | City-managed by Public Works | City replacement + penalties |
Not sure if your tree qualifies?
Measure first. An arborist consultation ($150–$300) is far cheaper than violation penalties. Call Community Development / Public Works at (650) 903-6306 — they can often tell you on the phone whether your tree is likely protected.
How to get a tree removal permit in Mountain View
Mountain View's permit process runs through Community Development / Public Works. Here's the step-by-step sequence:
Measure the circumference
Wrap a flexible tape around the trunk at 54 inches above grade. For oaks, redwoods, and cedars: 12 inches circumference (approximately 4 inches diameter) triggers protection. For all other species: 48 inches circumference (approximately 15 inches diameter).
Hire a certified arborist
An arborist report is required. The report must document the tree's condition, reason for removal, and whether alternatives are feasible. The City Arborist reviews every heritage tree application personally.
Submit to Community Development
File the Heritage Tree Removal Application with Community Development at (650) 903-6306. Pay the permit fee (approximately $100). Include arborist report, site plan, and photos.
City Arborist review
The City Arborist reviews the application and may visit the property. Expect 3–5 weeks for standard applications. Complex cases or trees on development sites may take longer.
Receive permit and schedule work
Once approved, hire a licensed tree service (CSLB C-61/D-49). Replacement planting is required per the City Arborist's specification. The permit must be on-site during work.
What happens if you remove a tree without a permit?
$5,000–$15,000+ in restoration costs
Mountain View imposes restoration costs of $5,000–$15,000 or more for unauthorized heritage tree removal. This includes the tree's appraised value, replacement planting at the city's specification, and site restoration. The City Arborist actively enforces violations and investigates neighbor reports.
A permit costs approximately $100 and takes 3–5 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 Mountain View?
Pruning that follows ISA standards and doesn't alter the tree's basic structure does not typically require a permit. Crown reduction, topping, or significant structural changes on heritage trees require city approval. The Tree Technical Manual provides pruning guidelines.
What if the tree is dead or hazardous?
Dead or hazardous trees can qualify for expedited removal. Contact Community Development at (650) 903-6306 and provide photos. The City Arborist may need to verify the hazard before approving emergency removal.
Why is the oak/redwood/cedar threshold so low?
Mountain View deliberately set the threshold at 12 inches circumference (approximately 4 inches diameter) for oaks, redwoods, and cedars to protect these slow-growing native species from their earliest established years. A coast live oak can take 10–15 years to reach just 4 inches in diameter. By comparison, Palo Alto's oak threshold is 11.5 inches diameter — roughly 36 inches circumference — nearly 3× higher.
