Before you call a tree company in the Portland south metro — or pick up a chainsaw yourself — there’s one question worth answering first about your tree removal permit: does your city require one?
The answer depends entirely on where you live. In some cities, you can take down almost any tree on your private property without paperwork. In others, removing a single medium-sized tree without a permit can cost you hundreds or thousands of dollars in fines.
We serve homeowners across a wide stretch of the Portland south metro and Willamette Valley, and permit rules vary dramatically from one city to the next — sometimes from one neighborhood to the next. Here’s a straight-talk breakdown for every city in our service area.
The Universal Tree Removal Permit Portland South Metro
Before getting into city-by-city differences, there’s one rule that applies everywhere: street trees always require a permit.
A street tree is any tree in the public right-of-way — typically in the planting strip between the sidewalk and the curb. Even though these trees sit in front of your house and you’re often responsible for maintaining them, they belong to the city. Removing one without authorization can result in significant fines and a required replacement at your expense, no matter which city you live in.
If you’re not sure whether a tree is on your private property or in the right-of-way, call us — we can help you figure it out before any work begins.
Permit Requirements by City
Beaverton
Most trees on private residential property in Beaverton do not require a removal permit. However, Beaverton has designated certain trees as protected — including those in Significant Tree/Grove zones, Historic Tree/Grove designations, Significant Natural Resource Zones, and trees designated as Landscape Trees. These zones are not always visible on public maps, so if you’re unsure, call the Beaverton Planning Division at 503-526-2420 before proceeding.
Street trees: Always require a permit. Contact Beaverton Urban Forestry at 503-526-3724.
Tigard
In Tigard, single-family homeowners can generally remove trees on their private property without a permit — with some important exceptions. A permit is required if the tree is a street tree, a median tree, a heritage tree, a tree planted using the Urban Forestry Fund, or a native tree in a sensitive area (steep slopes, 100-year floodplain, stream corridors, wetlands, or significant habitat areas).
If you’re not sure whether your tree falls into one of those categories, Tigard’s Urban Forestry department can help, or we can advise you during a site visit.
Street trees: Always require a permit. Contact Tigard Community Development at 503-718-2421.
Sherwood
Sherwood
Sherwood’s tree regulations focus primarily on street trees. For private residential property, the rules are relatively flexible — but street tree removals follow a specific permit process with fees and posting requirements.
Private Property Trees
Trees on private single-family residential property in Sherwood generally do not require a removal permit. However, if you need to remove more than 5 trees on your property, a permit is required regardless of tree size or species. For most residential jobs this limit is not an issue — but it’s worth knowing before planning a larger clearing project.
Street Trees — Permit Required
Any street tree measuring 5 inches or greater DBH (diameter at breast height) requires a Street Tree Removal Permit before removal. All trees within a planter strip are considered street trees. If your tree is in a front yard without a planter strip, contact Sherwood Planning to confirm whether it qualifies as a street tree.
How the Permit Process Works:
Step 1 — Submit a Street Tree Removal Permit Application through the state’s ePermitting system or contact Sherwood Planning directly.
Step 2 — A 10-day notice is posted on site. If no comments are received during the notice period, the permit is typically granted.
Step 3 — Permit fees: $25 for the first tree, $10 for each additional tree. Permits are processed on Fridays.
Step 4 — Trees over 10″ DBH require an ISA-certified arborist report describing the tree’s condition and the specific reason for removal. We prepare this documentation as part of the permit process.
Step 5 — A replacement tree is required within 6 months of removal. An exemption is available with a letter from a certified arborist — we prepare this when applicable. A root barrier is required for all new and replacement street trees.
Contact Sherwood Planning at planning@sherwoodoregon.gov or 503-925-2308. Applications are submitted through Oregon’s ePermitting system.
Street trees: Always require a permit. Contact Sherwood Planning at 503-925-2308.
Lake Oswego
Lake Oswego has one of the more comprehensive tree codes in the region. A permit is required to remove any tree 6 inches DBH (diameter at breast height) or greater on private residential property. DBH is measured at 4.5 feet above the ground — roughly chest height.
There are two types of private tree removal permits:
-
- Type 1 — No application fee. For trees that are dead, hazardous, or otherwise qualify for streamlined approval.
-
- Type 2 — $50 application fee. For elective removals or more complex situations, requires a public notice period.
Dead and hazardous trees are generally approved through the Type 1 process with appropriate documentation. Applications can be submitted to the Lake Oswego Planning Department by email at trees@lakeoswego.city or in person.
Street trees: Always require a permit. Contact Lake Oswego Planning at 503-635-0290.
West Linn
West Linn has a broad tree ordinance. A permit is required for all trees within city limits that meet these size thresholds:
-
- Oregon White Oak, Pacific Madrone, and Pacific Dogwood: 6 inches DBH or greater
-
- All other species: 12 inches DBH or greater
Emergency removals (storm damage, immediate hazards) must be reported to West Linn’s non-emergency dispatch at 503-635-0238. For standard removals, permit applications are processed by West Linn Parks & Recreation — budget up to 30 business days for review.
Street trees: Always require a permit. Contact West Linn Parks & Recreation at 503-557-4700 or email treepermits@westlinnoregon.gov.
Tualatin
In Tualatin, single-family homeowners can remove up to 4 trees per year without a permit — unless the tree is a Heritage Tree, located in a wetland, or within a Clean Water Services vegetated corridor. If you want to remove more than 4 trees in a year, you’ll need to submit a single-family tree removal permit through the Tualatin Planning Division.
Trees 8 inches or greater in diameter on private property are regulated under Chapter 33 of the Tualatin Development Code, so when in doubt, check with the city before starting work.
Street trees: Always require a permit. Contact Tualatin Parks and Recreation at 503-691-3061.
Wilsonville
Wilsonville requires a permit to remove any tree 6 inches DBH or greater on private property. There are three permit types depending on the scope of work:
-
- Type A — Up to 3 trees per property per calendar year
-
- Type B — 4 or more trees on a single property (apply through the City’s Online Permitting Portal)
-
- Type C — Required for site development work
Pruning does not require a permit in Wilsonville, but all work must follow ANSI A300 standards, and tree topping is prohibited.
Street trees: Always require a permit. Contact Wilsonville Planning at 503-682-4960.
Oregon City
Oregon City requires a permit for removing trees on private single-family lots — but the good news is that these permits are free of charge. You’ll apply through the Oregon City Planning Department, and replacement may be required depending on the circumstances.
For hazardous trees, an ISA Certified Arborist report strengthens your application. If replanting on-site isn’t feasible, alternatives include planting a tree on another property in Oregon City, donating a tree to city parks, or paying a mitigation fee as a last resort.
Street trees: Always require a permit. Contact Oregon City Planning at 503-657-0891.
Canby
In Canby, residents can remove up to 2 trees per year on private property without a permit. The same applies to commercial properties (up to 2 trees per year, per acre). Removing additional trees requires a more detailed permit through the Canby Public Works Department.
Street trees: Always require a permit. Contact Canby Public Works at 503-266-0759.
Newberg
Newberg is relatively homeowner-friendly: if you own a single-family home, the city does not require a permit to remove trees on your private property. The main exception is trees within a stream corridor overlay zone — those require approval before removal. Commercial, multifamily, and institutional properties have additional rules, particularly for trees required as part of a design review approval.
Street trees: Always require a permit. Contact Newberg Planning at 503-537-1240.

What About Emergency Removals?
When a tree fails in a storm and poses an immediate safety threat, the normal permit process doesn’t always apply — but you should still notify your city as soon as possible after the emergency work is done. Most cities have provisions for emergency removals, but documentation (photos, an arborist’s written assessment) protects you if questions arise later.
If a branch or tree comes down on your property during a storm, call Grove Tree Care at 503-208-4071. We handle emergency work throughout our service area and can help document the situation for city reporting requirements.
