Mom-and-Pop Landlord Rules in Oregon 2026
Small landlord exemptions from just-cause eviction and rent control laws
Oregon is one of the few states where the size and legal structure of your ownership genuinely changes which laws bind you. If you are a natural person who owns a building of four or fewer units and lives in one of them, Oregon's statewide just-cause and rent-cap regime largely does not apply to you. The carve-outs sit in ORS §90.427(7) on the termination side and ORS §90.600(1)(c) on the rent-increase side, and they reach a second group too: an individual whose only rental property is a single-family home, even one the owner does not live in.
Miss the fine print, though, and the exemption evaporates. Put the title in an LLC, add a fifth unit, or move out of the building, and you fall back under the statewide 7-percent-plus-CPI rent cap and just-cause termination rules of SB 608 that govern every other Oregon landlord.
Who Qualifies as a "Mom-and-Pop" Landlord in Oregon?
The term "mom-and-pop landlord" typically refers to an individual or family that owns a small number of residential rental units, often 1 to 4, and frequently lives in or near the property. In states with tenant-protection legislation, the legislature has carved out exemptions recognizing that small landlords operate differently from large institutional property managers.
Because Oregon has active just-cause or rent-control legislation, small landlords must understand whether they qualify for an exemption, and structure their ownership accordingly to preserve that protection.
What Oregon's small-landlord carve-out actually covers
The main exemption has three conditions, and all three must hold at once: the building contains 1–4 units, the owner is a natural person (not an LLC, corporation, or other entity), and that owner lives in one of the units. Satisfy the trio and the SB 608 rent cap and just-cause requirements step aside.
There are two more lanes worth knowing:
- A single-family home owned by a natural person as their only rental is exempt even without owner-occupancy. This is the classic accidental-landlord scenario, one house, one tenant.
- Buildings within 15 years of their certificate of occupancy are exempt from the rent cap, but not from just-cause. A new fourplex can still price freely at renewal, yet its owner still needs a qualifying reason to end a tenancy.
The SB 608 regime you are stepping out of
Understanding what the exemption is worth means understanding what everyone else lives under. SB 608 (2019) imposed a statewide rent cap of 7% plus CPI per year, codified for rent increases at ORS §90.600(1)(c), and paired it with a just-cause termination requirement, a framework HB 2001 further shaped. On Oregon's average rent of $1,268, the 7% component alone works out to roughly $88 a month of headroom before the CPI adjustment is added, so covered landlords plan every renewal around that ceiling.
An exempt owner-occupant of a duplex faces neither constraint: no statutory cap on the renewal increase, and no obligation to show a qualifying cause under ORS §90.427(7). That is a materially different business than the one a covered twelve-unit owner runs across town.
The duties that never shrink with portfolio size
The exemption is a shield against SB 608, not against the rest of the Oregon Residential Landlord and Tenant Act, ORS chapter 90. Four obligations apply to a one-house landlord exactly as they apply to an institutional one:
- Habitability. ORS §90.320 sets the baseline condition of the rental, and no unit count waives it.
- Anti-retaliation. ORS §90.385 bars punishing a tenant for asserting their rights, including through rent hikes an exempt owner could otherwise impose.
- Entry notice. Oregon requires 24 hours of notice before entering an occupied unit. Owner-occupants sharing a building with tenants trip over this constantly.
- Fair housing, discrimination law does not scale with size.
A working playbook for the 1-4 unit Oregon owner
If the exemption is your operating advantage, protect it deliberately:
- Deeding the property to an LLC or corporation forfeits the exemption, the statutes require a natural person on title. Weigh that against whatever liability benefit the entity offers before you transfer.
- Document owner-occupancy: keep utility bills, voter registration, or a homestead record tying you to your unit, so an exemption claim survives a tenant challenge.
- Relying on the single-family lane? It only works while that house is your only rental. Buying a second rental ends it.
- Remember the 15-year new-construction window relieves only the rent cap, just-cause still applies to those buildings.
- Keep serving 24-hour entry notices and answering ORS §90.320 repair duties; those follow you regardless of status.

Frequently Asked Questions
Am I exempt from Oregon's just-cause eviction law as a small landlord?
You are exempt if you are a natural person who owns a 1-4 unit building and lives in one of the units, under ORS §90.427(7). A natural person whose only rental is a single-family home is also exempt, even without living there. Note the asymmetry for new construction: buildings within 15 years of their certificate of occupancy escape the rent cap but not just-cause.
Can I raise rent freely if I qualify for the exemption?
Owners covered by the carve-out sit outside the statewide 7% plus CPI cap in ORS §90.600(1)(c), so no statutory ceiling applies to their increases. Every other Oregon landlord is bound by the SB 608 cap. One limit survives for everyone: an increase imposed to punish a tenant for asserting their rights is retaliation under ORS §90.385, exemption or not.
Which Oregon rules still apply to me no matter how small I am?
The whole of ORS chapter 90 outside the SB 608 carve-outs: the habitability standard in ORS §90.320, the anti-retaliation protections in ORS §90.385, the 24-hour entry-notice requirement, and fair housing law. The exemption changes how tenancies end and how fast rent can rise; it changes nothing about how the unit must be maintained or how tenants must be treated.
Does living in the building really change my legal position?
For the 1-4 unit lane, owner-occupancy is the hinge of the entire exemption: a natural person who owns the building and occupies one unit is outside SB 608, and the same owner who moves out is inside it. The single-family lane is the exception, since a natural person's only rental home qualifies without owner-occupancy. Keep records proving which unit you live in.
