Tenants keeping unauthorized pets in rental properties is no rare occurrence, even when your rental already allows pets. It is common for renters to attempt to keep an animal that the pet policy does not allow, or to avoid pet deposits and fees by never registering the animal with the property management. This issue has become even more common as pet ownership has stayed elevated well beyond pre-pandemic levels. The best way to prepare for unauthorized pets on your Oregon rental is to understand the state’s pet laws and create a standardized procedure that is outlined in the lease in the event of the discovery of an unauthorized pet.
Pet Laws in Oregon
Landlords in Oregon have the ability to enforce their own curated pet policy, with a few caveats. It is completely legal to ban pets in the rental property altogether, as well as ban certain types of pets and breeds, or enforce size limits. Popularly, landlords choose pet policies that only allow cats and dogs under a certain weight, or ban certain breeds that are more likely to be aggressive or cause property damage. The number of animals a household may keep is usually a matter of local city ordinance in Oregon rather than a statewide rule. Landlords also have the ability to revoke an individual pet’s residence if they can reasonably determine that the animal poses a threat to the safety of other tenants or the property. In terms of finances, Oregon is one of the few states that places no statutory cap on security deposits, so it is legal to require an additional refundable pet deposit, and monthly ‘pet rent’ can be charged on top of the original rent price.
Deposits, Pet Rent, and Oregon’s Refund Rules
Because there is no deposit ceiling in Oregon, the more important rule is how the money has to be handled. Oregon Revised Statutes section 90.300 treats a pet deposit as part of the refundable security deposit, which means it has to be accounted for and returned, along with an itemized list of any deductions, within 31 days of the tenant moving out. It is completely legal to fold a pet deposit into the deposit you already hold, as well as charge separate monthly pet rent, which commonly runs somewhere between $25 and $75 per pet and does not count as a deposit. What Oregon does not really allow is a flat, non-refundable ‘pet fee,’ since any pet money that functions like a deposit has to remain refundable, so the safer structure is a refundable deposit plus pet rent.
Could Oregon Force Landlords to Allow Pets?
There has also been talk of going further. House Bill 2070, introduced in the 2025 session, would ban pet rent and separate recurring pet fees for cats, dogs, and companion animals, although landlords could still require a refundable deposit and recover for any damage. As of 2026 that bill remains in committee and has not become law, and there is no Oregon statute that forces a landlord to accept pets, so owners are still free to set and enforce their own pet policies within the limits above.
Service Animals, ESAs, and Declawing Rules
The restrictions on pet policies in Oregon largely align with federal tenant protections, with one notable difference. Unlike California, Oregon has no law that prevents a landlord from requiring a pet to be declawed or devocalized, so that particular question is left to the lease. Where Oregon does constrain the landlord is disability accommodation. Under the federal Fair Housing Act, and under Oregon’s own anti-discrimination provisions in ORS 90.390 and 659A.145, a tenant may always request a waiver of a no-pet policy or a pet restriction in the case of a service animal, and this includes emotional support animals. ORS 90.300 states plainly that a landlord may not charge a pet deposit for a service or companion animal that a tenant with a disability requires as a reasonable accommodation, and the animal cannot be restricted by size, weight, or breed the way an ordinary pet can. The landlord may ask for written verification of the disability-related need when it is not obvious, the tenant remains responsible for any damage the animal causes, and the accommodation can still be refused if the specific animal is confirmed to be a genuine threat to the safety of other residents. One thing to watch is that federal officials pulled back their long-standing guidance on emotional support animals in 2025 and 2026, but that shift did not rewrite the Fair Housing Act or Oregon’s own protections, so the safe course is to keep accommodating assistance animals and confirm the current requirements before turning any request down.
Dealing With Unauthorized Pets
The best way to handle unauthorized pets with full legal protection is by including a clearly defined pet policy in every lease. The pet policy section should include property rules concerning pets as well as a predetermined procedure in the event of an unauthorized animal discovered on the premises. In addition to prohibited pets being kept on the property, any pet that is not properly registered to avoid additional fees is an unauthorized pet and can be handled with the same procedure. Landlords can require the tenant to submit official pet information such as breed, weight, and current vaccinations in order to confirm that the animal is within the pet policy guidelines.
When a tenant is keeping an unauthorized pet, this can be considered a violation of the lease, and just as with any violation, following standard and formal procedures is always smart. In Oregon the landlord delivers a written for-cause notice under ORS 90.392 that gives the tenant at least 14 days to correct the violation, with the tenancy ending no sooner than 30 days out if the animal is not removed or brought into compliance. If the same violation happens again within six months, a 10-day notice can be issued with no further chance to cure. If the tenant does not resolve the problem within the specified time frame, the landlord can choose to begin an eviction, and the official notice should make that intention clear from the start.
Frequently Asked Questions
How much can a landlord charge for a pet deposit in Oregon?
Oregon does not cap security deposits, so there is no fixed dollar limit on a pet deposit. As of 2026, a pet deposit is treated as part of the refundable security deposit under ORS 90.300, which means it has to be itemized and returned, minus any documented deductions, within 31 days of move-out. Monthly pet rent, which commonly runs between $25 and $75 per pet, is separate and is not refundable, while a flat non-refundable pet fee is legally risky because Oregon requires pet charges to be handled as refundable deposits.
Can a landlord evict a tenant for an unauthorized pet in Oregon?
Yes, keeping an unauthorized pet is considered a violation of the lease, and it is handled like any other for-cause violation under ORS 90.392. The landlord first serves a written notice giving at least 14 days to correct it, remove the animal or register it properly, with termination no sooner than 30 days out. If the pet is not removed within that window, or the violation repeats within six months, the landlord can choose to begin an eviction.
Do Oregon landlords have to allow emotional support animals?
Emotional support animals must be accommodated even where a no-pet policy is in place, because both the federal Fair Housing Act and Oregon’s anti-discrimination law protect tenants with disabilities. A tenant may request the accommodation so long as they provide written verification of the disability-related need, and the landlord cannot charge a pet deposit, fee, or pet rent for the animal or restrict it by size, weight, or breed. Federal enforcement of requests for untrained support animals narrowed in 2025 and 2026, but Oregon’s own protections remain in force, so confirm the current rules before denying a request.
