1. The Portland OR Metro Rental Market in 2026

The Portland metropolitan area is one of the most legally complex rental markets in the United States, combining a statewide rent control framework (Oregon’s 9.5% cap for 2026), a city-level overlay in Portland that substantially exceeds state protections, a three-county court system, and two significant mid-market county-split traps that have cost landlords dismissed eviction filings. The metro stretches across Multnomah County (Portland, Gresham), Washington County (Beaverton, Tigard, Hillsboro), and Clackamas County (Lake Oswego, West Linn, Oregon City), with Portland and Gresham sharing a single downtown courthouse, Beaverton and Tigard sharing a courthouse in Hillsboro 17 miles west of Portland, and Lake Oswego split between two courthouses depending on which neighborhood the property is in.

Oregon was the first state in the United States to enact statewide rent control (2019, HB 2001), creating the foundational framework that SB 611 (2023) refined into the current 9.5% cap formula. For 2026, that cap is 9.5% — 7% fixed plus the Oregon CPI-U component of approximately 2.5%, with a hard ceiling of 10% regardless of CPI. The cap applies to all residential buildings statewide with a certificate of occupancy (CO) dated on or before December 31, 2010. Buildings with CO dates from January 1, 2011 onward are exempt for 15 years from their CO date — a provision that has preserved rent flexibility in Portland’s post-2010 construction boom neighborhoods but is now approaching expiration for the earliest exempt buildings (2011 CO buildings lose their exemption on January 1, 2027).

The 90-day advance notice requirement (ORS §90.600(11)) is the most operationally disruptive element of Oregon’s rent law for landlords accustomed to other states. No other state requires 90 days’ advance written notice for all rent increases regardless of size. Oregon landlords must plan rent increases 90 days before they take effect — meaning a lease renewal effective September 1 requires the rent increase notice to be served no later than June 2 (or May 30, accounting for mailing). Landlords who serve notice in July for a September renewal miss the cycle entirely and must wait until the following year.

Portland’s local Rental Services Bureau (PREB) framework adds a third compliance layer on top of the state law. Inside Portland city limits, landlords face tripled relocation assistance obligations for no-fault terminations (3 months instead of 1 month), annual registration requirements with PREB, enhanced documentation requirements for non-renewal, and additional just-cause procedural steps. Outside Portland city limits — in Beaverton, Tigard, Lake Oswego, Gresham, and Tualatin — the statewide rules apply without the Portland overlay, creating meaningfully different compliance burdens for properties separated by only a few miles or even a few blocks in border areas.

The six-city metro analyzed here — Portland, Beaverton, Gresham, Lake Oswego, Tigard, and Tualatin — represents the core economic geography of a region anchored by three massive employment clusters: the Washington County technology corridor (Nike World HQ in Beaverton with ~12,000–15,000 Portland metro employees; Intel Hillsboro with ~20,000+ workers making it Oregon’s largest private employer; and dozens of semiconductor and tech firms), the healthcare cluster (OHSU ~18,000 employees in Portland; Providence Health ~12,000+ systemwide in metro; Legacy Health ~12,000+), and the Portland metropolitan business core (financial services, government, creative industries, logistics). These employment anchors generate the tenant demand that makes Portland metro one of the most active rental markets on the West Coast.

2. Oregon Legal Framework — ORS §90.323 / SB 611 Statewide Rent Cap

2.1 The 9.5% Cap Formula for 2026

Oregon’s statewide rent increase cap is set annually by the formula in ORS §90.323 as amended by Senate Bill 611 (2023): the maximum allowable increase is 7% plus the percentage change in the Oregon CPI-U (Consumer Price Index for All Urban Consumers, Portland-Salem metropolitan area) for the calendar year two years prior, with a hard ceiling that the total never exceeds 10%. For 2026, Oregon’s applicable CPI-U component is approximately 2.5%, producing a 9.5% cap. The Oregon Housing and Community Services department publishes the official annual cap figure each September for the following calendar year.

The cap applies per 12-month period per rental unit. A landlord may not impose more than one rent increase per unit within any 12-month period. The 12-month period runs from the date of the last increase, not from a calendar year. A landlord who raises rent on March 1, 2026 cannot impose another increase until March 1, 2027 at the earliest — regardless of the calendar year cap in effect at that time. The cap in effect for 2027 will be recalculated based on the 2025 CPI-U data and could be higher or lower than 9.5%.

2.2 Buildings Covered vs. Exempt

The cap applies to all residential rental units in Oregon in buildings where the certificate of occupancy (CO) was issued on or before December 31, 2010. Buildings with a CO issued January 1, 2011 or later are exempt from the cap for 15 years from the CO date. After 15 years, the exemption expires and the unit becomes cap-subject. This creates a rolling exemption expiration that Portland metro landlords with post-2010 buildings must track carefully.

For 2026 specifically: all units in buildings with CO 2010 or earlier are cap-subject at 9.5%. A 2011 CO building is exempt through December 31, 2026, then becomes cap-subject on January 1, 2027. A 2015 CO building is exempt through December 31, 2030. A 2020 CO building is exempt through December 31, 2035. Portland saw significant apartment construction from 2011 through 2019 in neighborhoods like the Pearl District, South Waterfront, Lloyd District, Central Eastside, and inner NE — all of those buildings will reach cap-subject status between 2026 and 2034. Beaverton’s Round corridor and Downtown Beaverton saw similar activity; Tigard Triangle had major multifamily development 2012–2020.

Exempt buildings are not exempt from the 90-day notice requirement (ORS §90.600(11)) or the once-per-12-months frequency limit. The exemption only removes the percentage ceiling on the increase amount.

2.3 The 90-Day Advance Notice Requirement (ORS §90.600(11))

ORS §90.600(11) requires that any landlord intending to raise rent give the tenant at least 90 days’ written notice before the increase takes effect. This applies to all rent increases — whether the building is cap-subject or exempt, whether the increase is 1% or 9.5%, whether the tenancy is month-to-month or fixed-term. There is no exception for small increases, no expedited notice option, no waiver.

The 90-day requirement is the longest mandatory advance notice for rent increases in the United States. For comparison: California requires 30 days for increases of 10% or less and 90 days for increases over 10% (Civil Code §827). Washington state (HB 1217) requires 180 days for increases over 10% and 20 days for smaller increases. New York generally requires 30–90 days depending on lease type. Oregon’s flat 90-day rule for all increases regardless of size is uniquely restrictive.

Notice must be in writing. For mailed notice, add 3 days to the 90-day minimum (ORS §90.155). A notice served by mail on April 1 has an effective earliest effective date of July 5 (90 days + 3 days mailing). A landlord who serves mailed notice on May 1 for a July 1 lease renewal does not have a valid notice — only 61 days of notice, 32 days short. The rent increase is unenforceable and the tenant may continue paying the old rent. The landlord must re-serve the notice and wait the full period.

2.4 Oregon Just-Cause Eviction (ORS §90.427)

Oregon’s just-cause eviction statute (ORS §90.427) applies after a tenant has occupied a unit for 12 months. During the first 12 months of a tenancy, a landlord may terminate a fixed-term lease at its expiration without cause, or give 30-day notice to terminate a month-to-month tenancy without cause. After 12 months, all terminations and non-renewals require a qualifying just-cause reason from one of two categories.

For-cause reasons (tenant fault): non-payment of rent; material breach of the rental agreement after proper notice and failure to cure; repeated violation of the rental agreement (more than twice in 12 months); committing or allowing a nuisance on the property; criminal activity threatening health or safety; substantial damage to the property; misrepresentation of income or rental history on the rental application; and several other enumerated grounds. For-cause terminations use the Oregon cure-notice process: 72-hour notice for first non-payment within any 12-month period (the tenant has 72 hours to pay all unpaid rent or vacate); 6-day no-cure notice for a second non-payment incident within the same 12-month period (no cure option, tenant must vacate).

No-fault reasons (landlord business reason): the landlord intends in good faith to demolish or substantially renovate the unit; convert the unit to non-residential use; personally occupy the unit or have a qualified family member occupy it (owner-move-in); or sell the property to a buyer who intends to personally occupy it. For no-fault terminations after 12 months, the landlord must: give 90-day written notice AND pay relocation assistance. Statewide relocation: one month’s rent. Portland PREB relocation: three months’ rent.

2.5 Security Deposit Rules (ORS §90.300)

Oregon imposes no statutory cap on the security deposit amount. Landlords may charge any sum as a deposit. This distinguishes Oregon from California (SB 267: 1 month cap for most units as of July 2024), Washington state, and most other West Coast states. Portland metro landlords in high-cost neighborhoods routinely collect deposits of $3,000–$8,000+ on premium units without statutory violation.

The 31-day deposit return deadline (ORS §90.300(7)) is strict: within 31 days after the tenancy terminates and the tenant vacates, the landlord must either return the full deposit or return the balance remaining after itemized deductions, accompanied by a written itemized accounting of all deductions. Failure to return within 31 days triggers the 2× wrongful withholding penalty (ORS §90.300(16)): the tenant may recover the full withheld amount plus an amount equal to twice the withheld sum. A $5,000 deposit wrongfully withheld past the 31-day deadline = up to $15,000 tenant recovery. The 2× penalty applies regardless of whether the landlord had valid grounds for deductions — the remedy is for the procedural failure of late return, not for the substantive question of which deductions are valid.

3. Portland Local Rules — PREB and the Enhanced Relocation Framework

3.1 What PREB Is and Who It Covers

The Portland Rental Services Bureau (PREB) administers Portland City Code Title 30 (Rental Housing), which adds a layer of tenant protections beyond Oregon state law for all residential rental properties within Portland city limits. PREB is not a rent board in the traditional California sense — it does not adjudicate individual rent disputes or require pre-approval for rent increases. Instead, PREB functions as a registration and enforcement agency for Portland’s specific local ordinances, which primarily concern: (1) relocation assistance obligations; (2) non-renewal and just-cause documentation; and (3) certain disclosure requirements.

PREB jurisdiction applies to all residential rental properties within Portland city limits regardless of size — from single-unit in-law suites to large apartment complexes. Properties in Beaverton, Tigard, Gresham, Lake Oswego, and Tualatin are NOT subject to PREB even if the owner has a Portland address or the property is just outside city limits. The Portland city boundary is the relevant dividing line, not the county line or the ZIP code boundary.

3.2 Portland’s 3-Month Relocation Requirement

Portland City Code §30.01.085 requires that any landlord issuing a no-fault termination notice to a Portland tenant who has occupied the unit for 12+ months pay relocation assistance equal to three months’ rent. This applies to all qualifying no-fault reasons: owner-move-in, demolition, substantial renovation, conversion, or sale to owner-occupant. The relocation assistance payment must accompany the 90-day notice — a no-fault notice issued without the relocation payment is defective and invalid.

Three months’ rent means three times the actual monthly rent at the time the notice is issued. For a $1,600/month studio in NE Portland: $4,800 relocation payment. For a $2,400/month two-bedroom in the Pearl District: $7,200. For a $3,500/month Lake Oswego lakefront unit (outside Portland, statewide rules): $3,500. The cost asymmetry between Portland and nearby suburban jurisdictions is significant and affects landlord decisions about which properties to sell, renovate, or occupy.

Portland’s 3-month requirement has no exception for owner-occupants who inherit or recently purchased a property, no exception for small landlords, and no hardship waiver process. The payment is a requirement regardless of the landlord’s financial situation. Landlords who issue a Portland no-fault notice and then discover they cannot afford the relocation payment are in a difficult position: they cannot withdraw the notice without potential exposure, and they must pay before the notice is valid.

3.3 Portland PREB Just-Cause Documentation

Portland requires that non-renewal notices for tenants past 12 months specify the qualifying just-cause reason in writing, include the tenant’s rights under PREB (in a prescribed form), and in some circumstances be filed with PREB. The city periodically updates its required disclosure forms — landlords should download the current PREB forms rather than using older versions. A non-renewal notice that uses an outdated form or omits required disclosures is defective even if the underlying reason is valid.

For-cause terminations within Portland also benefit from PREB documentation: landlords who maintain PREB-required records of lease violations, proper notice service, and repair/maintenance compliance are better positioned in FED proceedings where tenant attorneys may raise habitability defenses. PREB has a mediation program that some landlords have used to resolve disputes without filing a formal FED action, though participation is voluntary.

4. Three-County Court System — FED Jurisdiction Map

Oregon forcible entry and detainer (FED) cases are filed in the Circuit Court of the county where the rental property is physically located. The Portland metro area has three circuit courts serving six cities, with two significant property-level splits that complicate correct court identification.

Oregon FED proceedings move on an expedited schedule: ORS §105.135 requires the court to set the hearing within 6 calendar days of the filing. This is one of the fastest FED schedules in the US (for comparison, California requires 3–21 days for the first hearing; Texas typically 8–10 days; North Carolina 7–14 days). The 6-day timeline means a landlord who files on Monday should be in court by Sunday; in practice courts typically schedule hearings within 5–7 business days. The speed of the Oregon FED process is an advantage for landlords once the notice period has expired — but it makes correct notice service and correct county filing even more critical, since errors are quickly exposed.

4.1 The Lake Oswego County Split — Dunthorpe/Riverdale Trap

Lake Oswego is predominantly in Clackamas County, and most Lake Oswego eviction filings belong at Clackamas County Circuit Court in Oregon City (807 Main St). However, the northern strip of Lake Oswego — including the Dunthorpe neighborhood, the Riverdale area, and properties on and near SW Palatine Hill Rd north of the primary Lake Oswego city area along the Willamette River — falls within Multnomah County. These properties file at Multnomah County Circuit Court in Portland (1021 SW Fourth Ave).

The split creates particular risk because: (1) Dunthorpe and Riverdale are among Oregon’s most expensive residential areas, with estate homes commonly rented at $5,000–$15,000+/month; a single dismissed FED filing due to wrong-county filing means months of delay and potential significant lost rent; (2) the properties are often marketed as “Lake Oswego” regardless of which county they’re in; and (3) the county line runs through neighborhoods without obvious street-level indicators. The Dunthorpe neighborhood straddles the boundary: some properties on SW Palatine Hill Rd are Multnomah County; others one block away are Clackamas County.

Verification method: Multnomah County property records at multcoproptax.com; Clackamas County Assessor at clackamas.us/at. Enter the specific property address and confirm the county on the assessor record. Do not rely on mailing city, ZIP code, or neighborhood name. Any Lake Oswego property north of SW Bertha Blvd / SW Palatine Hill Rd near the Willamette should be verified before any FED filing.

4.2 The Tualatin County Split — SW Boones Ferry Road Line

Tualatin is divided between Washington County (northwest, central, and most residential areas) and Clackamas County (southeast, roughly south and east of SW Boones Ferry Rd and SW Tualatin-Sherwood Rd). The dividing line is approximately the SW Boones Ferry Rd / SW Tualatin-Sherwood Rd corridor running through the city, but the county boundary is not perfectly aligned with these roads and shifts by individual parcels in several locations.

Washington County Tualatin properties file at Washington County Circuit Court in Hillsboro (150 N First Ave). Clackamas County Tualatin properties file at Clackamas County Circuit Court in Oregon City (807 Main St). Both addresses are in different cities entirely — a landlord who drives to the wrong courthouse loses the day’s filing slot and may miss cure-notice deadlines in time-sensitive FED situations.

Verification method: Washington County Assessor at wcatlas.co.washington.or.us; Clackamas County Assessor at clackamas.us/at. Any Tualatin property near or south of SW Boones Ferry Rd, SW Tualatin-Sherwood Rd, or in the Tualatin-Sherwood Rd / I-5 industrial corridor should be verified. Properties east of I-5 in Tualatin are often Clackamas County. Properties in Tualatin Commons area (west/central) are typically Washington County.

5. City-by-City Analysis

5.1 Portland (Multnomah County)

Portland is Oregon’s largest city (~640,000 population) and the metro’s economic anchor. The city spans both the west side of the Willamette River (West Hills, Northwest Portland, Pearl District, Downtown) and the larger east side (Northeast, Southeast, North Portland, Lents, Outer East). Rental stock ranges from pre-war Craftsman homes and 1920s–1940s apartment buildings in inner neighborhoods (all cap-subject, CO pre-2010 by many decades) to modern glass-tower apartments in the Pearl District and South Waterfront (many CO 2011–2020, cap-exempt but approaching expiration windows).

Portland is the only city in the metro subject to both Oregon statewide law AND Portland local PREB rules. Every Portland landlord must comply with: (1) ORS §90.323 9.5% cap for covered buildings; (2) ORS §90.600(11) 90-day notice; (3) ORS §90.427 just-cause after 12 months; (4) Portland City Code §30.01.085 3-month relocation on no-fault terminations; and (5) PREB registration and disclosure requirements. The combined compliance burden is higher than any other Portland metro city.

Major employers driving Portland rental demand: State of Oregon government (Governor’s office, ODOT, DAS, and dozens of agencies; 35,000+ state employees in Portland metro); City of Portland (~8,000 employees); Portland Public Schools (~7,000 employees); OHSU (Oregon Health & Science University) ~18,000 total employees including Doernbecher Children’s Hospital, Casey Eye Institute, and Knight Cancer Institute — Oregon’s largest employer in the healthcare sector; Providence Portland Medical Center (~6,000 employees); Legacy Emanuel Medical Center (~4,000 employees); Legacy Good Samaritan Medical Center (~3,000 employees); Portland VA Medical Center (~5,000 employees); PeaceHealth (~2,000 Portland metro); Daimler Trucks North America (Portland headquarters; ~4,000 employees in the Portland area; manufactures Freightliner and Western Star); Portland General Electric (PGE; ~3,500); Precision Castparts (aerospace manufacturing; ~25,000 globally, ~3,500 Portland metro); Intel (significant Portland city presence in addition to Hillsboro flagship); Portland’s technology and creative economy (Jama Software, Planar Systems, Cambia Health Solutions, and hundreds of smaller tech firms).

Portland rent ranges (1BR, 2026): Inner SE / Hawthorne / Division: $1,300–$2,000; Pearl District / South Waterfront: $1,600–$2,800 (many newer buildings, CO 2011+, still exempt); NW Portland / Nob Hill: $1,400–$2,200; Northeast (Alberta Arts, Mississippi Ave, Concordia): $1,100–$1,800; North Portland (St. Johns, Arbor Lodge): $950–$1,600; Outer SE (Lents, Woodstock, Foster-Powell): $900–$1,500; Downtown / West Hills: $1,500–$2,600.

5.2 Beaverton (Washington County)

Beaverton (~105,000 population) is Oregon’s sixth-largest city and the heart of the Washington County technology corridor. Its identity is shaped almost entirely by one employer: Nike, Inc., whose World Headquarters campus at 1 Bowerman Dr occupies 286 acres in Beaverton and employs approximately 12,000–15,000 people in the Portland metro area out of ~44,000 global employees. Nike’s compensation structure ($90,000–$250,000+ for campus roles) creates a significant premium tenant pool in Beaverton’s newer apartment stock.

Intel Hillsboro (formally in Hillsboro, the Washington County seat, ~8 miles from central Beaverton) also drives strong Beaverton rental demand. Intel is Oregon’s largest private employer with ~20,000 employees in the Hillsboro campus cluster (D1X, D1D, Ronler Acres, Jones Farm campuses). Intel employees earning $80,000–$200,000+ frequently rent in Beaverton for its proximity to Intel via OR-8/Cornell Road and the Washington County tech amenities. Providence St. Vincent Medical Center (~6,500 employees, 509-bed Level II Trauma) at the Portland/Beaverton border also contributes significant healthcare workforce demand.

Beaverton is NOT subject to Portland local PREB rules. A Portland landlord who purchases a Beaverton property and applies Portland relocation assistance rules (3 months) is over-complying — the statewide rule (1 month) applies. Conversely, a Beaverton landlord who somehow believes Portland rules don’t apply should note that Oregon statewide law (90-day notice, 9.5% cap, just-cause) applies throughout Oregon including Beaverton.

Beaverton’s rental market has significant new construction from 2011–2020 in the Downtown Beaverton / BTC corridor (Beaverton Town Center, Round at Beaverton Central), Murrayhill, and Progress Ridge submarkets. Many of these buildings are still cap-exempt (CO 2011+) but approaching expiration on the earlier ones. Beaverton School District is Oregon’s second-largest (40,000+ students) and drives school-boundary premium pricing in family-unit rentals.

Beaverton rent ranges (1BR, 2026): Downtown / Beaverton TC: $1,500–$2,200; Nike / Murray Blvd corridor: $1,600–$2,300; Aloha / unincorporated west: $1,200–$1,700; Progress Ridge / Murrayhill: $1,500–$2,100; Cedar Hills: $1,300–$1,900.

5.3 Gresham (Multnomah County)

Gresham (~115,000 population) is Oregon’s fourth-largest city, positioned as the eastern bookend of the Portland metro along the I-84 / Historic Columbia River Highway corridor. Despite its size, Gresham is often overlooked in Portland metro rental analysis — it lacks a major corporate employer, its housing stock skews older and more affordable, and its reputation as a logistics and light-industrial center creates a distinct tenant profile from the tech-driven west side.

Courthouse trap — most important Gresham fact: Gresham is Multnomah County. All Gresham FED eviction filings go to Multnomah County Circuit Court at 1021 SW Fourth Ave, Portland OR 97204 — there is no circuit court in Gresham, no local courthouse, no Gresham-specific FED venue. Landlords who have never filed a Multnomah County eviction and assume a “Gresham courthouse” exists will find no such facility. Drive 20 miles west to Portland to file.

Gresham tenant demand drivers: Amazon (Troutdale FC/PDX1 logistics facility employing ~2,000+; ~10 miles northeast of Gresham central); FedEx Ground (Orient Dr distribution hub; ~1,500+ workers); Legacy Mount Hood Medical Center (127-bed community hospital at SE 282nd Ave; ~1,200–1,500 employees); Mount Hood Community College (~7,000 students; significant workforce training enrollment); Gresham-Barlow School District (~10,000 students; ~1,400 employees); MAX Blue Line and Green Line service (Blue Line operates every 15 minutes to Portland downtown; Green Line via Gateway). Gresham’s primary rental demand comes from logistics workers, MHCC students, and lower-income households priced out of inner Portland and southeast suburbs.

Gresham’s rental market is 30–40% below inner SE Portland. Most Gresham stock is pre-2011 and cap-subject at 9.5%. Portland PREB rules DO NOT apply in Gresham (outside Portland city limits). Gresham’s own municipal code does not include PREB-equivalent relocation requirements — statewide rules (1 month relocation for no-fault) apply. For landlords seeking yield on affordable Portland metro inventory, Gresham’s lower acquisition prices and statewide (not Portland-enhanced) compliance burden make it attractive, offset by higher vacancy sensitivity and the drive to the Portland courthouse.

Gresham rent ranges (1BR, 2026): Downtown Gresham / MAX station: $950–$1,500; Central / MHCC corridor: $900–$1,400; North Gresham (Troutdale Rd area): $850–$1,300; East Gresham (unincorporated border): $800–$1,200.

5.4 Lake Oswego (Clackamas County majority / Multnomah County Dunthorpe strip)

Lake Oswego (~40,000 population) is Oregon’s most affluent suburb, with a median household income exceeding $130,000 — among the highest in the Pacific Northwest. The city’s identity is anchored by two defining features: the private Oswego Lake (controlled by Oswego Lake Corporation, which issues water access authorizations required for any dock, boathouse, or direct lake access — a critical due diligence item for landlords purchasing lakefront property) and Oregon Health & Science University (OHSU), whose main campus on the Marquam Hill / South Waterfront complex in Portland employs ~18,000 and generates massive demand for Lake Oswego housing among physicians and high-compensation healthcare professionals who prefer Lake Oswego’s top-rated school district (Lake Oswego School District; LOSD) and suburban character.

The county split is Lake Oswego’s most important compliance feature (see Section 4.1 above). Approximately 85–90% of Lake Oswego by area is Clackamas County; the Dunthorpe/Riverdale strip along the northern Willamette River bank is Multnomah County. A property marketed as “Lake Oswego, OR 97034” or “Lake Oswego, OR 97035” may be in either county. Clackamas County is the correct default for most Lake Oswego properties, but any northern property near the Multnomah County line must be verified.

Oswego Lake access due diligence: The Oswego Lake Corporation (OLC) controls the private Oswego Lake water rights and riparian access. Any rental property with a dock, boathouse, boat slip, or direct lake frontage requires an OLC access authorization. Landlords who purchase a lakefront property expecting to offer dock access must verify that OLC access runs with the property and is transferable to tenants under the existing authorization. Failure to disclose OLC requirements to tenants creates habitability and lease-compliance issues.

Lake Oswego’s premium rental market creates elevated deposit exposure: a $5,000–$8,000 security deposit (common for high-end Lake Oswego SFR) missed at the 31-day ORS §90.300 return deadline creates $10,000–$24,000 in potential 2× wrongful withholding liability. The combination of high deposits, premium rents, and sophisticated tenant profiles (OHSU attendings, Nike/Intel executives) means Lake Oswego landlords are frequently in disputes that reach the circuit court level.

Lake Oswego rent ranges (1BR/2BR/3BR, 2026): Downtown LO (1BR): $1,600–$2,600; East / Lakeview area (2BR): $2,000–$3,500; Westlake (2BR townhome): $2,200–$3,800; Lakefront SFR (3BR): $4,000–$8,000+; Dunthorpe estate (3BR+): $4,500–$12,000+.

5.5 Tigard (Washington County)

Tigard (~55,000 population) occupies the I-5 / I-217 interchange hub position in the south Washington County corridor — a strategic logistics and commuter point connecting Portland to Beaverton (north via I-217), to Salem and Eugene (south via I-5), and to Tualatin and Lake Oswego (south via I-5). Tigard lacks a single dominant employer but benefits from its proximity to Nike (8 miles north via I-217) and Intel (15 miles northwest via I-217 / OR-8), Washington Square Regional Mall (~2,000–3,000 workers), and the emerging Tigard Triangle mixed-use corridor along the 72nd Ave / SW Pacific Hwy corridor.

The Tigard Triangle is a distinct compliance microzone: the city has actively encouraged high-density mixed-use development since 2016, resulting in a significant wave of new apartment construction from 2014–2022. Many Tigard Triangle buildings received COs in 2015–2022 and are cap-exempt for 15 years from those dates (becoming cap-subject 2030–2037 respectively). Landlords acquiring Tigard Triangle properties in 2024–2026 should understand the specific CO year of each building and the resulting cap exemption calendar. A 2016 CO building is exempt through December 31, 2031 — a meaningful flexibility window for rent setting.

Tigard is Washington County (evictions at Washington County Circuit Court, Hillsboro). Portland PREB does not apply. Statewide Oregon rules apply: 9.5% cap for covered buildings, 90-day notice, just-cause after 12 months, 1-month relocation on no-fault. Tigard’s rent market runs 5–15% below Beaverton, reflecting its greater distance from the Nike campus and slightly lower commuter scores to Hillsboro Intel.

Tigard rent ranges (1BR, 2026): Downtown Tigard / Tigard Triangle: $1,400–$2,000; Washington Square area: $1,300–$1,900; Metzger (unincorporated): $1,200–$1,700; King City: $1,150–$1,700; Greenway / Summerfield: $1,100–$1,600.

5.6 Tualatin (Washington County / Clackamas County split)

Tualatin (~32,000 population) is the south anchor of the Washington County tech/logistics corridor, positioned at the I-5 / I-205 / OR-99W nexus and serving as the practical southern gateway to the metro for employers and logistics operations. Tualatin’s dual-county status (see Section 4.2) is its most critical compliance feature: the SW Boones Ferry Rd / SW Tualatin-Sherwood Rd line divides the city between Washington County (northwest/central; file Hillsboro) and Clackamas County (southeast; file Oregon City).

Key Tualatin employers: FLIR Systems / Teledyne FLIR (thermal imaging and surveillance technology; corporate headquarters at 6769 SW Boones Ferry Rd, Tualatin; ~1,500–2,000 Tualatin employees; part of Teledyne Technologies). Siemens EDA (formerly Mentor Graphics; electronic design automation; Wilsonville headquarters ~5 miles south; significant Tualatin employee presence). Amazon logistics (DuPont St distribution facility). Providence Health (operating network in the broader Washington County corridor). Brown & Caldwell, Precision Castparts (supply chain proximity). Tualatin’s employer base is diverse: manufacturing, defense tech, logistics, and engineering firms whose workforces earn $55,000–$150,000+.

Tualatin is frequently compared to Tigard by prospective renters and landlords — they share similar price points, both are Washington County majority (though Tualatin has the split), and both serve as bedroom communities for Beaverton/Hillsboro tech employment. Tualatin rents 10–20% below Tigard, reflecting its slightly further position from the Nike corridor and its industrial character. Portland PREB does not apply anywhere in Tualatin (outside Portland city limits).

Tualatin rent ranges (1BR, 2026): Tualatin Commons / Centerpointe: $1,300–$1,900; NW Tualatin (Washington County): $1,200–$1,700; SE Tualatin (Clackamas County side): $1,200–$1,800; near Boones Ferry / tech corridor: $1,100–$1,600.

8. The 10 Costliest Mistakes Portland Metro Landlords Make

1. Applying Portland PREB relocation rules to Beaverton, Tigard, or Gresham properties. Portland’s 3-month relocation requirement is Portland city limits only. Paying 3 months on a Beaverton no-fault termination over-complies and is not legally required — but more dangerously, landlords who confuse city/county boundaries may UNDER-apply Portland rules to Portland properties near the city line. Know which city limits your property is in.
2. Serving a 60-day or 30-day notice instead of a 90-day notice for a rent increase. Oregon requires 90 days regardless of increase size (ORS §90.600(11)). A 60-day notice is legally invalid. The tenant may ignore the increase, continue paying the old rent, and the landlord must re-serve a proper 90-day notice. Months of lost income on cap-limit increases.
3. Raising rent on a CO 2011+ exempt building beyond the 9.5% cap — or believing the exemption is permanent. The exemption lasts 15 years from CO. A 2011 building loses its exemption on January 1, 2027. Landlords who purchased post-2010 buildings expecting perpetual exemption must identify the CO year and calculate the expiration date. Raising rent above 9.5% on a cap-subject building (CO 2010 or earlier) is the flip side: landlords miscalculate the CO year and over-raise.
4. Filing a Lake Oswego eviction at Washington County Circuit Court (Hillsboro). Lake Oswego is Clackamas County (majority) or Multnomah County (Dunthorpe strip). Washington County has NO jurisdiction over Lake Oswego properties. Filing in Washington County = immediate dismissal. Verify county before filing.
5. Filing a Tualatin SE eviction at Washington County Circuit Court when it’s Clackamas County. The SW Boones Ferry Rd line divides Tualatin. Properties southeast of that line are Clackamas County — file Oregon City. Driving to the Washington County courthouse in Hillsboro and filing a Clackamas County Tualatin property = dismissal.
6. Missing the 31-day deposit return deadline and triggering the 2× wrongful withholding penalty. ORS §90.300 is absolute: 31 days after tenancy termination and vacation. Lake Oswego landlords with $5,000–$8,000 deposits face $10,000–$24,000 potential exposure for late return. Set calendar alerts on move-out day; send itemized accounting the same day via certified mail.
7. Serving a 72-hour non-payment notice twice within 12 months (second occurrence should be 6-day). Oregon law provides a cure right on the first non-payment within any 12-month period (72-hour notice). The second non-payment within the same 12-month period entitles the landlord to a 6-day no-cure notice — no cure option for the tenant. Landlords who serve a second 72-hour notice accidentally give the tenant an opportunity to cure and restart the clock.
8. Issuing a Portland no-fault termination notice without the 3-month relocation payment. Portland City Code requires the relocation payment to accompany the notice. A notice served without the payment is defective — the termination is invalid regardless of the landlord’s reason. The landlord must re-serve with payment. The 90-day clock only starts from a valid notice with payment.
9. Not verifying just-cause requirement applicability because the tenant “just moved in.” After 12 months, ORS §90.427 applies. A month-to-month tenancy that has run for 13 months requires just-cause for termination. Landlords who give a 30-day notice to “not renew” a month-to-month after 12 months violate just-cause requirements — the notice is invalid.
10. Collecting a large deposit without tracking the 31-day return calendar or maintaining documentation of deductions. Oregon has no deposit cap, so high deposits are legally permissible. But without documenting move-in condition (dated photos, signed inspection report), every deduction will be disputed and the landlord may lose the ability to prove damage beyond normal wear. High deposit + poor documentation + late return = the most expensive combination in Oregon landlord-tenant law.

9. Oregon FED Process — Step-by-Step

Oregon’s forcible entry and detainer (FED) process is among the fastest in the US, moving from filing to hearing in 6 calendar days per ORS §105.135. The timeline below assumes proper notice has been served and expired.

1. Serve proper notice. Non-payment (first): 72-hour notice per ORS §90.394. Non-payment (second in 12 months): 6-day no-cure notice. No-fault after 12 months: 90-day notice + relocation payment (1 month statewide; 3 months Portland). For-cause material breach: 30-day notice with opportunity to cure.
2. Wait for notice period to expire. The notice period must expire before filing. Filing on day 72 of a 72-hour notice (counting from delivery) is technically one day early if served at close of business. Count carefully.
3. Verify property county using county assessor records (Multnomah / Washington / Clackamas).
4. File FED complaint at the correct circuit court. Bring: written notice served on tenant; proof of service; lease agreement; any relevant documentation. Filing fee varies by county (~$75–$100).
5. Court sets hearing within 6 calendar days (ORS §105.135). Summons is served on the tenant.
6. Attend hearing. Bring original lease, all notices served (with proof of service), photos of any damage, payment records. If tenant raises habitability defense (warranty of habitability under ORS §90.360), be prepared with repair documentation.
7. Obtain judgment for possession and/or damages. If tenant fails to appear, landlord typically receives default judgment.
8. If tenant appeals: tenant has 10 days to appeal to the Circuit Court. Appeal stays the eviction pending a de novo hearing.
9. Request Writ of Execution (Oregon’s equivalent of Writ of Possession) if tenant remains after judgment and no appeal.
10. Sheriff executes lockout. Sheriff schedules within a few days of Writ issuance.

Uncontested timeline from 72-hour notice to lockout: approximately 3–4 weeks for non-payment FED (72-hour notice period + filing + 6-day hearing scheduling + judgment + Writ + Sheriff scheduling). Portland PREB compliance does not change the FED timeline for for-cause terminations — it primarily affects no-fault terminations, which require the 90-day notice + relocation payment before any FED process begins.

10. 12-Step Compliance Checklist for Portland Metro Landlords

• Verify property county on county assessor records before any filing or compliance calculation (Multnomah / Washington / Clackamas). Do not rely on mailing city or ZIP code.
• Determine if Portland city limits apply. If yes: PREB registration, 3-month no-fault relocation, Portland just-cause disclosure forms required. If no: statewide Oregon rules only.
• Identify the CO date of your building. CO 2010 or earlier: 9.5% cap applies for 2026. CO 2011–2025: cap-exempt, but track 15-year expiration date. CO 2011 buildings become cap-subject January 1, 2027.
• Calculate the maximum allowable rent increase for the current 12-month period: current rent × 1.095 for cap-subject buildings. Note: the 9.5% cap for 2026 may change in future years; verify the current-year cap with Oregon Housing and Community Services each September.
• Serve 90-day advance written notice per ORS §90.600(11) before any rent increase. Add 3 days for mailed notice. Mark the effective date and the 90-day + mailing deadline on the calendar before signing the notice.
• Confirm once-per-12-months frequency. Do not serve a second rent increase notice within 12 months of the last effective increase date.
• Collect security deposit with documentation. Take dated photos and a signed move-in inspection report on the day of tenant possession. Oregon has no deposit cap — document thoroughly to support any future deductions.
• Return deposit within 31 days of tenancy termination and vacation (ORS §90.300(7)). Set a calendar alert on move-out day. Send certified mail with itemized accounting to forwarding address (and last known address if no forwarding provided) before day 31.
• For non-payment: serve 72-hour cure notice (1st occurrence in 12 months). If tenant cures, tenancy continues. If second occurrence within 12 months, serve 6-day no-cure notice.
• For no-fault termination after 12 months: confirm qualifying reason under ORS §90.427. Calculate relocation assistance: Portland = 3 months’ rent (send with notice); statewide = 1 month’s rent (send with notice). Serve 90-day written notice with payment enclosed.
• File FED at the correct circuit court. Multnomah County (Portland, Gresham): 1021 SW Fourth Ave, Portland. Washington County (Beaverton, Tigard, central Tualatin): 150 N First Ave, Hillsboro. Clackamas County (most Lake Oswego, SE Tualatin): 807 Main St, Oregon City.
• Verify county split properties before filing. Lake Oswego north strip (Dunthorpe/Riverdale) = Multnomah County. Tualatin SE (south/east of SW Boones Ferry Rd) = Clackamas County. Confirm on county assessor records for any property near these boundary lines.
