Monmouth, Oregon is a small city of roughly 10,000 residents in Polk County, anchored by Western Oregon University. Because of the university's presence, a substantial share of Monmouth residents are renters — students and long-term community members alike — making knowledge of landlord-tenant law especially valuable here. Renter concerns in Monmouth most commonly center on security deposit disputes, rent increases, and eviction procedures.
Tenant rights in Monmouth are governed primarily by the Oregon Residential Landlord and Tenant Act (ORLTA), codified at Oregon Revised Statutes (ORS) Chapter 90. Oregon is one of only a handful of states with a statewide rent stabilization law, which limits how much landlords can raise rent each year for qualifying units. Monmouth has not enacted any local tenant-protection ordinances beyond what state law provides.
This article is intended as a general educational resource for Monmouth renters and is not legal advice. Laws can change, and your specific situation may require guidance from a licensed Oregon attorney or a legal aid organization.
Monmouth has no city-level rent control ordinance. However, Oregon enacted statewide rent stabilization in 2019 under ORS 90.323, making it the first state in the nation to establish a rent increase limit at the state level. This law caps annual rent increases at 7% plus the Consumer Price Index (CPI) for the Western Region, calculated each year by the Oregon Department of Administrative Services.
Importantly, the cap applies only to dwelling units that are at least 15 years old at the start of the calendar year. Units first occupied within the past 15 years are fully exempt from the rent stabilization cap under ORS 90.323(5)(a). Single-family homes where the landlord has provided proper written notice of the exemption may also be exempt if the landlord meets the criteria under ORS 90.323(5)(b).
In practice, this means many Monmouth renters in newer apartment complexes near Western Oregon University may not be protected by the rent cap. For units that do qualify, landlords are prohibited from raising rent more than once in any 12-month period (ORS 90.323(2)), and they must provide at least 90 days' written notice before any rent increase takes effect (ORS 90.493).
Habitability (ORS 90.320): Oregon law requires landlords to maintain rental units in a habitable condition. This includes keeping the premises weatherproof and watertight, providing functioning plumbing and heating, ensuring the property is free of pest infestations, and maintaining common areas in a safe and sanitary condition. A landlord who fails to address a habitability issue after proper written notice from the tenant may face rent reduction, repair-and-deduct remedies, or termination of tenancy by the tenant under ORS 90.365.
Notice Requirements (ORS 90.427 & ORS 90.493): For month-to-month tenancies, a landlord must provide at least 30 days' written notice to terminate during the first year of occupancy, and at least 90 days' written notice after the first year. After the first year, a termination notice must also state a legally qualifying reason (just cause). Rent increases require at least 90 days' prior written notice under ORS 90.493.
Anti-Retaliation (ORS 90.385): Landlords are prohibited from retaliating against tenants who exercise their legal rights — such as complaining about habitability issues to a government agency, requesting repairs, or organizing with other tenants. Retaliatory acts include raising rent, reducing services, or filing for eviction within 90 days of a protected activity. Tenants who face retaliation may recover one to three months' rent plus actual damages.
Lockout and Utility Shutoff Prohibition (ORS 90.375): Self-help eviction is illegal in Oregon. A landlord may not remove a tenant's belongings, change the locks, or willfully cut off utilities (heat, water, electricity) in an attempt to force a tenant out. Violations entitle the tenant to recover up to two months' rent plus actual damages.
Domestic Violence Protections (ORS 90.453): Tenants who are victims of domestic violence, sexual assault, or stalking have the right to terminate a lease early with 14 days' notice and appropriate documentation, without penalty for early termination.
Oregon law governs security deposits in detail under ORS 90.300. There is no statutory cap on the amount a landlord may charge as a security deposit in Oregon, meaning landlords can set any amount they choose. However, all deposit terms must be disclosed in the written rental agreement.
Upon termination of the tenancy, the landlord must return the tenant's security deposit — along with an itemized written accounting of any deductions — within 31 days of the tenancy ending and the landlord receiving the tenant's forwarding address. Allowable deductions include unpaid rent and charges for damage beyond ordinary wear and tear.
If the landlord fails to return the deposit or provide the required accounting within 31 days without a legally sufficient reason, the tenant may be entitled to recover twice the amount wrongfully withheld plus the deposit itself, under ORS 90.300(14). Tenants should document the condition of the unit at move-in and move-out (with dated photographs) and provide a written forwarding address to the landlord to protect their rights and start the 31-day clock.
The eviction process in Oregon is governed by ORS Chapter 105 (forcible entry and wrongful detainer) and ORS Chapter 90. Landlords must follow a strict legal process — they may never resort to self-help measures such as changing locks or removing a tenant's belongings (ORS 90.375).
Step 1 — Written Notice: Before filing for eviction, a landlord must serve the tenant with proper written notice. The type and length of notice depends on the reason:
Step 2 — Filing in Court: If the tenant does not comply or vacate within the notice period, the landlord may file a Forcible Entry and Wrongful Detainer (FED) complaint in Polk County Circuit Court. The tenant is then served with a summons and has the right to appear and contest the eviction at a hearing, typically scheduled within 7–15 days of filing.
Step 3 — Hearing and Judgment: At the hearing, both the landlord and tenant may present evidence. If the court rules in the landlord's favor, a judgment for restitution is issued. The tenant typically has a short period — often 4 days — to vacate before the landlord can request a writ of execution and involve the sheriff.
Just Cause Requirement (ORS 90.427): After a tenant has lived in a unit for more than one year, the landlord must state and document a legally qualifying reason for termination, such as the owner moving in, demolition/conversion, or a material lease violation. A landlord who cannot establish just cause cannot evict a tenant who has resided there over a year simply by giving notice.
