Multnomah County, OR Rental Property Rules: Just Cause Eviction (2026)

ORS 90.427 requires just cause for eviction of any tenant who has occupied a unit more than 12 months (or after the first lease term for fixed-term leases). Qualifying tenant-based causes include nonpayment of rent, material breach of the rental agreement, outrageous conduct, and three warnings in 12 months. Qualifying landlord-based (no-fault) causes include landlord move-in, demolition or substantial renovation requiring 60+ days vacancy, sale to a buyer who will owner-occupy, and conversion to non-residential use. No-fault terminations require 90 days written notice AND one month's rent paid to the tenant as relocation assistance (ORS 90.427(7)). Within Portland city limits, PCC 30.01.085 replaces the state one-month relocation payment with tiered assistance of $2,900 (studio), $3,300 (1BR), $4,200 (2BR), or $4,500 (3+BR). The Portland FAIR ordinance PCC 30.01.086 also mandates specific screening criteria and application timelines. Multnomah County has enacted Ordinance 1294 (2019) requiring countywide compliance and establishes the County Rent Assistance Program. Retaliatory evictions are prohibited under ORS 90.385. Domestic violence victims receive additional protections under ORS 90.449.
