What extra rules apply to rentals inside Portland city limits?
The short answer
Portland layers city ordinances on top of Oregon state law, including additional requirements around applicant screening and security deposits, and mandatory renter relocation assistance triggered by certain rent increases and no-cause terminations. Properties in Multnomah County but outside city limits are not covered by these.

City rules sit on top of state rules
Complying with Oregon law is not the same as complying in Portland. The city adds its own requirements, and they apply in addition to, not instead of, the statewide rules.
Portland's ordinances include additional structure around how applicants are screened and how security deposits are handled, beyond what state law requires.
Relocation assistance
Portland requires landlords to pay mandatory relocation assistance to tenants in defined circumstances, including certain rent increases above a threshold and no-cause terminations.
The amounts are set by the city and are substantial relative to a month's rent. This is the Portland rule that most often surprises an owner who has only read state law.
City limits, not county lines
The boundary that matters is Portland city limits, not Multnomah County. Gresham is in Multnomah County and outside the city, so Portland's ordinances do not apply there.
Owners get this wrong in both directions: over-complying on a Gresham property, or assuming a Portland address is governed only by state law.
Why this one bites
Relocation assistance can turn a routine rent increase into a four-figure obligation. It is the clearest example of why the city boundary, not the county, is the line that matters.
Common questions
Does Portland have rental rules beyond Oregon state law?
Yes. Portland adds city ordinances covering applicant screening, security deposits, and mandatory renter relocation assistance in defined circumstances. They apply in addition to state law.
What is Portland renter relocation assistance?
A city requirement that landlords pay tenants a set relocation amount in defined circumstances, including certain rent increases above a threshold and no-cause terminations.
Do Portland's rental ordinances apply in Gresham?
No. Portland's ordinances apply inside Portland city limits. Gresham is in Multnomah County but outside the city, so state and county rules apply there instead.
This is a summary, not legal advice.
Oregon landlord-tenant law changes, and how a rule applies depends on the specific property and tenancy. Figures set annually by the state, such as the rent-increase cap, change year to year.
