When Do You Need a Tree Removal Permit in Portland?
Portland made headlines in June 2025 when the city announced it would eliminate most tree removal permit fees. The move was welcome news for homeowners frustrated with complicated codes and additional fees. However, far too many homeowners took this news as an idea that they did not need a permit for tree removal anymore, which couldn’t be further from the truth.
Tree removal permits are still required for most trees 12 inches in diameter or larger, and the penalties for skipping this step haven’t changed. In fact, removing a tree without the required permit can result in fines up to $1,000 per tree, per day of violation. Whether you’re in Portland, West Linn, or Lake Oswego, understanding when you need a permit and actually getting one is just as important as ever.
Key Takeaways
- Portland eliminated most tree removal permit fees as of July 2025, but permits are still required and replanting requirements still apply.
- West Linn and Lake Oswego have different permit rules — West Linn requires permits for most trees 12 inches+ (or 6 inches for protected species), while Lake Oswego uses a tiered system based on size and location.
- Removing a tree without a permit in Portland can cost you up to $1,000 per tree per day, plus you’ll still be required to pay for replacement trees and may face delays on future permit applications.
- Property owners are ultimately responsible for obtaining tree removal permits even when hiring a tree service company, which means you face the penalties if your contractor removes a tree without the required permit.
- Emergency tree removals involving immediate safety threats, like actively failing trees or fallen trees blocking streets, still require permits in most cases, though the process may be expedited or retroactive depending on your municipality.
Tree removal permits in Portland are now free, but homeowners still need to submit applications and receive approval before removing regulated trees.
Do I Need a Tree Removal Permit in Portland Metro?
Whether you need permits depends on where you live and the size of the tree. Portland, West Linn, and Lake Oswego each have their own permit requirements, though they all regulate tree removal to some degree.
Portland Permit Requirements
As of July 2025, Portland eliminated most tree removal permit fees. Tree Removal & Replanting Permits that previously cost around $35 are now free, and Replanting Waiver fees dropped from $100 to $50. These changes were funded through the Portland Clean Energy Community Benefits Fund.
Free doesn’t mean not required though. If you have a tree on private property that measures 12 inches or more in diameter at breast height (DBH), you’ll need a permit before removing it.
However, any tree in the city right-of-way requires a permit regardless of size, and so do Heritage trees, which are marked with city signs. When you remove a tree, Portland requires you to plant replacement trees, either tree for tree or up to inch for inch, with a minimum size of 1.5 inches caliper.
West Linn Permit Requirements
West Linn’s tree removal requirements are more restrictive than Portland’s, with special protections for certain species.
The general threshold is 12 inches DBH, but three species have special protection: Oregon white oak, Pacific madrone, and Pacific dogwood require permits when they reach just 6 inches DBH. If you have a multi-trunk tree, it’s measured at 54 inches above ground, and the diameters are added together for the total.
The process takes 30 days, with 20 days for the permit process and a 10-day window for appeals.
Lake Oswego Permit Requirements
Lake Oswego tree removal permits follow a two-tier system. Type I is for smaller trees on single-family residential properties. These come under lower scrutiny and have a $26 fee. Type II covers most large tree removals and goes through a more extensive review. Fees start at $261 and increase by $26 for each additional tree.
Some trees have extra protection, including those that were required as part of development permits, trees within Historic Landmark areas, and trees on city property.
Lake Oswego also requires replanting of new trees to offset the lost specimen. Depending on the size of the tree you have removed, this may be one or two new trees. The city also requires homeowners to plant certain species from its native tree list.
What Happens If You Remove a Tree Without a Permit?
According to Portland City Code Title 11, Chapter 11.70, the city can impose civil penalties up to $1,000 per tree, per day of violation for unlawful tree removal. Each tree constitutes a separate violation, which means the fines can accumulate quickly. The city also requires you to pay for replacement trees even after any fines are paid.
Beyond immediate fines, violations can lead to other consequences. The City Administrator can delay the processing of future permit applications from property owners who have violated the tree code. For contractors and tree service companies that violate the code, the city can disqualify them from city contracts for up to two years and remove them from the city’s list of approved local tree care providers.
One important thing to understand is that the property owner is ultimately responsible for obtaining required permits, even when hiring a tree service company. If your contractor removes a tree without getting the necessary permit, you as the property owner will face the penalties. This is why it’s critical to work with a credible and certified tree service that helps with permitting and always follows local requirements.
“In our 30-plus years serving Portland Metro, we’ve seen how permit requirements can catch homeowners off guard. The city eliminated fees to make permits more accessible, but that doesn’t change the requirement itself. We always verify permit needs during the initial estimate because protecting our clients from violations is just as important as protecting their property during the tree work.” – Mark Bourgeois, founder of ArborPro Tree Experts
Can You Remove a Tree in an Emergency Without a Permit?
Emergency tree situations require immediate action, but the permit process still applies, just with different timelines and procedures depending on which city you’re in. Understanding what qualifies as a true emergency and how your local jurisdiction handles urgent tree situations can help you stay compliant while protecting your property.
A genuine tree emergency involves an immediate safety threat that can’t wait for the standard permit process. This includes trees that have already fallen and are blocking streets or damaging structures, trees actively failing or leaning with imminent collapse risk, large broken limbs hanging over buildings or walkways, or storm-damaged trees posing clear danger to people or property.
Trees that have been dead for months or those that you simply want removed for convenience don’t qualify as emergencies.
PRO TIP: The requirements for how and when to apply for a retroactive permit for emergency removal differ between municipalities. Ask your tree service about them during an emergency removal to ensure you keep your project legal and compliant with local regulations.

How Can an Arborist Help with Tree Removal Permits?
An arborist can measure your tree properly and tell you whether it meets the size threshold for a permit in your city. This initial assessment helps you understand your requirements before making any decisions about the tree.
For trees that do require permits, many tree service companies will handle the application process as part of their service. This includes preparing all the paperwork, taking the required photos, creating site maps, and communicating with city permit offices. They’re familiar with what each city requires and what information needs to be included for approval.
The permit process can take time. A tree service company that regularly works with permits in your city will know how to factor this timeline into your project schedule.
If you’re planning for professional tree removal, it’s worth asking the tree service company about their experience with local permits during your initial consultation. Understanding who will handle the permit and what the timeline looks like can help you plan accordingly.
Frequently Asked Questions About Tree Removal Permits
How do I measure my tree to know if I need a permit?
Measure diameter at breast height (DBH), 4.5 feet above ground on the uphill side. Wrap a measuring tape around the tree for circumference, then divide by 3.14 for diameter. For example, a 38-inch circumference equals about 12.1 inches diameter, requiring a permit in Portland. Our arborists measure and photograph your tree during free estimates.
Do I need a permit to remove a dead tree in Portland?
Yes, you will need a permit if the tree is 12 inches or larger in DBH. Portland requires permits for dead trees just like living trees, though dead trees often get easier approval.
How long does it take to get a tree removal permit approved in Portland?
Portland processing can take anywhere from a few days to months, depending on demand and the permit type. Apply well before you need work done, especially during the peak spring season.
Who is responsible for getting the tree removal permit — the homeowner or the tree service company?
The property owner is ultimately responsible, even if your tree service fails to inform you. Many professional tree removal companies (including our team at ArborPro) offer permit application services. Always clarify in your written contract who handles permits before work begins.
Crane-assisted removals allow ArborPro’s team to safely remove large trees in confined spaces while minimizing property damage and disruption.
