Oregon rent increases for week-to-week and manufactured-home tenancies

Oregon's seven-day week-to-week notice and separate manufactured-dwelling or marina rules do not fit the ordinary 90-day apartment checklist.

Oregon's ordinary shorthand—one year, ninety days, and the annual state percentage—does not describe every tenancy. Week-to-week tenancies have a seven-day written-notice rule. Manufactured-dwelling and floating-home facility tenancies can fall under ORS 90.600 and a separate percentage calculation.

The classification must come before the arithmetic. Choosing the ordinary apartment path for a weekly tenancy or a manufactured-home space can produce a confident but wrong date or percentage.

Week-to-week means a defined tenancy

ORS 90.323 says that for a week-to-week tenancy the landlord may not increase rent without at least seven days' written notice before the effective date. That is different from the first-year and ninety-day language that applies to tenancies other than week-to-week.

A tenant paying weekly is not necessarily in a statutory week-to-week tenancy. Oregon's definition includes specific features of the rental arrangement. Review the written agreement and actual terms instead of selecting the category solely from the payment frequency.

Manufactured-home space rules are a separate chapter path

ORS 90.323 expressly does not apply to tenancies governed by ORS 90.505 to 90.850. Those provisions cover manufactured-dwelling and floating-home facility relationships, including rent increases under ORS 90.600. Renting a manufactured home as a dwelling is not always the same as owning the home and renting space in a facility.

Identify who owns the home, what is being rented, and whether the property is a statutory facility. The word 'mobile home' in an advertisement is not enough to select the facility rule.

The 2026 percentage rows

For 2026, Oregon DAS publishes a 6% maximum for tenancies subject to ORS 90.600(1) in facilities with more than thirty spaces. The standard published figure for smaller covered facilities and tenancy types subject to ORS 90.323 is 9.5%, subject to the statutes' details and exemptions.

A calculator should show which row it selected and why. If facility size or property classification is unknown, the result should request the missing fact rather than quietly use the higher number.

Timing and delivery still need review

The percentage is not the notice period. ORS 90.600 has its own timing and frequency rules for covered facility tenancies. For ordinary non-weekly tenancies, ORS 90.323 supplies the first-year and ninety-day path. Service by mail can interact with ORS 90.155.

Keep the notice date, effective date, service method, tenancy agreement, and facility information together. A notice that states the correct annual figure can still fail because it uses the wrong tenancy classification or date.

Use the checker without hiding uncertainty

RentCap asks for property type and tenancy type before it calculates. Choose 'not sure' when the agreement does not clearly establish the category; the result will keep the classification issue open. A renter can use that prompt to request the missing facility or lease facts.

Landlords can preview the calculation free and unlock the packet only after the facts support a useful result. RentCap provides self-help information, not legal representation. Facility classification and unusual weekly arrangements are good candidates for Oregon legal review before a notice is served or challenged.

Do not mix the dwelling and space-rental questions

A resident may rent a manufactured dwelling from its owner, own the dwelling while renting a space, or have another arrangement. The annual percentage, notice form, facility-size question, and chapter can differ. Document ownership of the structure and the subject of the rental agreement before selecting a cap row.

Facility managers should keep the current space count and governing statements with the calculation. Residents should preserve the facility agreement and any policy amendment. When a park changes size, ownership, or configuration, do not assume last year's classification remains correct. The official statute and DAS publication should be checked for the effective year of the increase.

Examples of classification mistakes

A furnished room billed every Friday may still lack the statutory features of a week-to-week tenancy. A manufactured home rented together with the land may be an ordinary dwelling-unit tenancy rather than a resident-owned home in a facility. A small park may use a different percentage row from a facility with more than thirty spaces. Each shortcut changes the output materially.

Ask neutral questions that establish the relationship: Who owns the home? What does the agreement say is being rented? Is the resident paying for a space? How many spaces are in the facility? What is the rental period, and does the agreement satisfy Oregon's definition? Do not coach the answer toward the lower or higher cap.

When documents conflict with day-to-day practice, retain both and seek review. The checker can calculate each supported scenario, but it should not silently decide which description governs. A lawyer or appropriate housing resource can evaluate the agreement and facts before a time-sensitive notice is served or contested.
