Do I Need a Tree Permit in Oakland?
Oakland enforces the strictest tree protection thresholds in the Bay Area: 4 inches DBH for oaks, bay laurel, and buckeye; 9 inches for other native species. Eucalyptus and Monterey pine are exempt. Violations carry penalties up to $1 million. Here's how to navigate the process.

Select your tree species and measure the trunk to get an instant answer based on Oakland's ordinance (Oakland Municipal Code Chapter 12.36).
Measure DBH at 4.5 feet above natural grade using a diameter tape or caliper.
What trees are protected in Oakland?
Oakland Municipal Code Chapter 12.36 establishes the strictest tree protection thresholds in the entire Bay Area. The thresholds vary by species: oaks, bay laurel, and buckeye require permits at just 4 inches diameter. All other native species require permits at 9 inches. However, eucalyptus globulus (blue gum) and Monterey pine are completely exempt — a legacy of Oakland's post-1991 Hills Fire recovery strategy. I've seen this exemption confuse many property owners, so double-check your tree's identification before assuming it's exempt.
| Species / Category | Protected at (DBH) | Notes | Penalty |
|---|---|---|---|
| Oak (Coast Live, Valley, etc.) | ≥4″ DBH | Measured at 4.5 feet above natural grade | Up to $1,000,000 per violation |
| Bay Laurel | ≥4″ DBH | Measured at 4.5 feet above natural grade | Up to $1,000,000 per violation |
| Buckeye | ≥4″ DBH | Measured at 4.5 feet above natural grade | Up to $1,000,000 per violation |
| Other native species | ≥9″ DBH | Includes native shrubs; measured at 4.5 feet | Up to $1,000,000 per violation |
| Eucalyptus globulus (Blue Gum) | EXEMPT | No permit required — fire management species | No permit needed |
| Monterey Pine | EXEMPT | No permit required — fire management species | No permit needed |
Oakland's penalties are the highest in the Bay Area
Violations can result in fines up to $1,000,000 per tree. This is not a typographical error — Oakland's severe penalties reflect the critical role of its urban forest in post-1991 Hills Fire recovery. When in doubt, get an arborist consultation ($300–$600) before taking any action. It's far cheaper than penalties.
How to get a tree removal permit in Oakland
The process runs through Oakland's Bureau of Planning, Tree Services Division. Here's the step-by-step sequence:
Identify the tree species and threshold
Oaks, bay laurel, and buckeye require permits at 4 inches DBH. Other native species require permits at 9 inches DBH. Eucalyptus globulus and Monterey pine are exempt. If you're uncertain of the species, hire an ISA Certified Arborist for identification.
Measure trunk diameter at 4.5 feet
Use a diameter tape or caliper to measure DBH at 4.5 feet above natural grade. If the measurement meets or exceeds your tree's threshold, the tree is protected and a permit is required.
Hire an ISA Certified Arborist for assessment report
An assessment report from an ISA Certified Arborist is required for all protected tree removal applications. The report documents tree condition, reason for removal, and alternatives. Budget $300–$600.
Submit to Tree Services Division
File the permit application with the Bureau of Planning, Tree Services Division. Include the arborist assessment report, site plan, and $434.20 permit fee. Processing typically takes 4–8 weeks for standard applications, 6–10 weeks for large protected trees.
City arborist site inspection
A city arborist will inspect the tree and your application during the review period. Be prepared to discuss the removal reason and any alternatives you've considered.
Receive permit and schedule removal
Once approved, hire a licensed tree service (CSLB C-61/D-49). The permit must be on-site during removal. Replacement planting will be required at a city-determined ratio.
What happens if you remove a tree without a permit?
Up to $1,000,000 per violation
Unauthorized removal of a protected tree in Oakland carries penalties up to $1,000,000 per violation. This is the steepest penalty in the entire Bay Area. Additional consequences include mandatory replacement planting and potential criminal liability in egregious cases. A permit costs $434.20 and takes 4–8 weeks. The penalties for skipping it are catastrophically higher.
Oakland's severe enforcement reflects the importance of the urban forest following the 1991 Oakland Hills Fire. Many property owners have learned this lesson the hard way. There is no financial scenario where unpermitted removal saves money.

Frequently asked questions
Is eucalyptus really exempt in Oakland?
Yes. Eucalyptus globulus (blue gum eucalyptus) and Monterey pine are specifically exempt from Oakland's tree removal permit requirements. This exemption reflects Oakland's management of fire-risk species after the 1991 Oakland Hills Fire. However, make sure you've correctly identified your eucalyptus species — other eucalyptus varieties may not be exempt.
Does pruning require a permit in Oakland?
Light maintenance pruning does not require a permit. Significant pruning that removes more than 25% of the canopy or substantially alters the tree's structure may require a permit for protected species. Contact Tree Services Division for clarification on your specific situation.
What if the tree is dead or hazardous?
Dead or hazardous trees may qualify for expedited removal. Document the hazard with photos and contact Oakland's Tree Services Division immediately. The city may grant emergency removal authority without the standard 4–8 week timeline. This is the only scenario where you should proceed without a standard permit.
Why does Oakland have the strictest thresholds in the Bay Area?
The 1991 Oakland Hills Fire killed 25 people and destroyed nearly 3,000 homes. Oakland's strict tree ordinance reflects the city's commitment to maintaining its urban forest canopy while managing fire risk. The city treats unauthorized tree removal very seriously, which is why the penalties are so steep.
Are replacement plantings required?
Yes. The city determines the replacement planting ratio based on the removed tree's size and species. You'll receive specific requirements in your permit. Plan on replacement planting occurring after removal is complete.
