Oregon uses its own vocabulary. The statute says "assistance animal" where the ADA says "service animal," and "trainee" where other states say "dog in training." Underneath the words, Oregon's law is one of the clearer ones: it lists the two questions, bans documentation demands outright, covers trainers, and sends complaints to a state labor agency instead of leaving you to the courts. Here's all of it in plain English, with section numbers for when you need them.
Federal law applies underneath. For the ADA baseline, see our service dog requirements guide; for how Oregon compares to other states, the 50-state guide.
What Counts: "Assistance Animal" and "Trainee"
ORS 659A.143 defines an assistance animal as a dog, or another animal designated by administrative rule, that is individually trained to do work or perform tasks for a person with a disability. The task has to relate to the disability, and comfort alone doesn't count, matching the ADA. An assistance animal trainee is an animal being trained to be one, and an assistance animal trainer is the person doing it. Psychiatric assistance dogs count. Emotional support animals don't count in public places, though Oregon housing law protects them. No certification, registration, or ID exists or is required.
Where You Can Go, and the Two Questions
A person with a disability may bring an assistance animal, and a trainer may bring a trainee, into any place of public accommodation and any state or local government service, in all areas open to the public or to business invitees. The statute then spells out the inquiry rules:
A business may not: ask about the nature or extent of your disability, or require documentation proving the animal is an assistance animal.
No admission fee, pet fee, or deposit may be charged for the animal or the trainee. You're liable for damage the animal actually causes, as anyone would be. The animal may be asked to leave only if it's not housebroken or is out of control and you don't fix it, and any safety requirement a business imposes has to be based on actual risk, not assumptions about dogs.
Trainers and Trainees
Oregon puts trainers on the same footing as handlers, in the same places, with the same no-fee rule. There's no state requirement for a vest, patch, or credential for a trainee, though most Oregon programs use one. Owner-trainers are covered the same as program trainers.
If a Business Denies You: BOLI
A violation of ORS 659A.143 is an unlawful practice under Oregon's civil rights law, which means the Bureau of Labor and Industries investigates it. The process:
- File a complaint with BOLI's Civil Rights Division within one year of the denial. It's free; the Division investigates, can conciliate, and can order remedies including damages.
- You can also sue in state court under ORS 659A for damages and attorney's fees. Oregon doesn't set a minimum dollar amount.
- A federal DOJ complaint under the ADA is available too, free and with no deadline. See our complaint guide.
Faking an Assistance Animal: Up to $1,000
Since 2019, it's an offense in Oregon to bring an animal that isn't an assistance animal or trainee into a public accommodation and falsely claim it is in response to the two questions, or to put false identification on it and bring it in. It's an unclassified violation, not a crime, with a fine of up to $1,000. The law was written to target pets in vests and leaves the two-question limit on real handlers untouched.
Interfering With or Injuring an Assistance Animal
ORS 167.352 makes it a Class A misdemeanor (up to 364 days and $6,250) to intentionally or knowingly injure or attempt to injure an animal the person knows or should know is an assistance animal, or to interfere with it while it's working. Separately, ORS 30.822 gives the handler a civil claim for damages against anyone who injures or steals an assistance animal, covering veterinary costs, replacement and retraining, and related losses.
Housing
Housing follows the federal Fair Housing Act and Oregon's reasonable accommodation law. In practice: a landlord can't refuse you or charge a pet fee or deposit for an assistance animal, which in housing includes emotional support animals and animals other than dogs; can't apply breed or size limits to the animal; and may ask for documentation of your disability-related need only when it isn't obvious. Disability Rights Oregon recommends making the request in writing. Housing complaints go to BOLI within one year, to HUD, or through the Fair Housing Council of Oregon.
Work
Bringing an assistance animal to your job is a reasonable accommodation request. Oregon employers may ask for documentation that the animal is trained and able to work in the setting, which doesn't have to come from a medical professional. BOLI handles employment complaints as well.
Licensing and Local Rules
Oregon counties license dogs, and state law exempts assistance animals from the license fee. You still register the dog with your county; you just don't pay. Multnomah, Washington, and Clackamas counties all handle this online. Leash laws apply to assistance animals except where a leash would interfere with the dog's work.
Air Travel From PDX
State law stops at the aircraft door. The PDX terminal is covered by the ADA and Oregon law; on the plane, the Air Carrier Access Act governs and airlines may require the DOT form. PDX has post-security relief areas in every concourse. Our flying guide has the forms and airline policies.

The Bottom Line
Oregon's statute does most of your arguing for you: two questions, no documentation, no fees, trainers included, written in state law. If a business ignores it, BOLI is a real enforcement route with a one-year window and no lawyer required. Learn the word "assistance animal," since that's what Oregon staff are trained on, and keep the rest of this page for when you need it.
