Rent Control & Rental Housing Rights

Rent Control

The Rent Control Ordinance, approved by voters in November 2020, went into effect January 1, 2021. It establishes a base rent of most rental units in Portland to the rent charged in June 2020, and caps the amount by which landlords may increase that rent annually. This ordinance is applicable to both long-term rental units and short-term rental units.

In addition, the Ordinance provides various protections to tenants, including notice of rent increases, additional notice or payments before evicting certain tenants, prohibiting discrimination on the basis of funding (such as Section 8 or GA), and notice of tenants’ rights to new tenants.

Lastly, this Ordinance established a Rent Board to conduct hearings in response to tenant complaints, mediate disputes between tenants and landlords, and consider landlords’ requests for rent increases outside the scope of this Ordinance.
