Short answer: Oregon mobile home park laws are some of the most protective in the country. Under ORS 90.600(1), a park needs 90 days’ written notice to raise month-to-month space rent, can do it only once in 12 months, and in a park with more than 30 spaces is capped at 6 percent a year by ORS 90.324(1)(a). If the park closes, ORS 90.645 requires 365 days’ notice plus a payment to each home owner.
The space-rental rules sit in ORS 90.505 to 90.850, a part of the Residential Landlord and Tenant Act written for people who own a manufactured dwelling or floating home and rent the space under it. The general no-cause termination rules in ORS 90.427 expressly do not apply to these tenancies (ORS 90.427(13)).

Space rent: notice, frequency and the cap
ORS 90.600(1) bars a park from raising month-to-month space rent without at least 90 days’ written notice to each affected tenant, more than once in any 12-month period, or by more than the maximum set under ORS 90.324(1). The notice must state the increase amount, the new rent, the effective date and, if the increase goes over the cap, the facts supporting an exemption (ORS 90.600(2)).
The cap depends on park size. ORS 90.324(1)(a), last amended in 2025, fixes it at six percent for facilities with more than 30 spaces. Smaller parks follow the same formula as apartments: the lesser of 10 percent or seven percent plus the West Region CPI. The Department of Administrative Services publishes the figures by September 30 each year.
The infrastructure exception
A large park can exceed the cap only through a narrow door in ORS 90.600(3)(c). The increase must be no more than 12 percent, replace the regular increase for that year, come at least five years after any earlier such increase, and pay for a significant infrastructure project. At least 51 percent of occupied spaces must approve it in a signed written vote. If the project is not substantially finished within 12 months of the promised date, the park must refund the excess without being asked. A park that raises rent above the cap without qualifying owes three months’ rent plus actual damages under ORS 90.600(4).
Worked example
Teodoro rents a space for $700 a month in an 80-space park in Redmond. On December 15, 2026, the manager delivers a written notice raising his rent effective April 1, 2027. That is more than 90 days out, so the timing works. Because the park has more than 30 spaces, the most it can add is six percent, or $42, for a new rent of $742. If the notice says $770, Teodoro can point to ORS 90.600(4): the overcharge exposes the park to three months’ rent plus his actual damages. The next increase cannot take effect before April 1, 2028.
Grounds and notice for eviction from an Oregon park
An Oregon park cannot end a space tenancy without a statutory reason. The main routes are:
- Unpaid rent: ORS 90.394(2) allows a 10-day notice served on the eighth day of the rental period or later, or a 13-day notice served on the fifth day or later. The notice must state the amount owed.
- Conduct or rule violations: ORS 90.630(1) allows termination on 30 days’ written notice for a material violation of law or the rental agreement, or for unpaid late charges, fees or utility charges. The notice must give at least 30 days to correct, or 3 days for a one-time act that is not ongoing, and suggest a way to fix it.
- Repeat violations: if substantially the same problem recurs within six months, ORS 90.630(6) allows a 20-day notice with no right to cure.
- Repeated late rent: ORS 90.630(10) permits a 30-day termination notice when rent has repeatedly been paid late under the conditions that subsection lists.
Problems with the home’s own physical condition follow a separate track. ORS 90.630(2) says those cases go only through ORS 90.632, not the general violation notice. Our Oregon eviction process guide explains the court side.
Selling your home in place
ORS 90.680(2) says a park may not deny your right to sell your home on the rented space, or make you move it, solely because of the sale. It also cannot require you to sell through the park on consignment (ORS 90.680(3)). If your buyer wants to stay, the park can require up to 10 days’ written notice of the sale and a written application from the buyer (ORS 90.680(8)).
The park then has seven days after a complete application to accept or reject the buyer, extended to 10 days if you skipped the advance notice (ORS 90.680(10)). If you agree to let the park sell your home on consignment, the written contract is limited to 180 days unless extended, and the park must pay your share within 10 days of the sale (ORS 90.680(4)).
Park closure and relocation payments
Closing all or part of a park for a different use requires at least 365 days’ written notice under ORS 90.645(1)(a)(A). The park must also pay each displaced tenant a base amount of $6,000 for a single-wide, $8,000 for a double-wide or $10,000 for a triple-wide or larger. Housing and Community Services recalculates those amounts for inflation by rule, so check the current figure. The payment is owed whether you move the home or leave it, and at least half must be paid within seven days after you give the required notice (ORS 90.645(4)).

Conversion to a subdivision is different. Under ORS 90.645(2), the notice period drops to 180 days, and no payment is owed to a tenant who buys their lot and keeps the home there, or who sells the home to someone who buys the lot.
Tenants committees and the chance to buy the park
Oregon gives organized residents two formal tools. First, under ORS 90.600(8), residents can elect a committee of up to seven members. On written request, the landlord must meet with it within 10 to 30 days, up to twice a year, and answer its written summary in good faith within 60 days.
Second, ORS 90.842 requires an owner to give written notice to all tenants, or to an existing purchase committee, before marketing the park or when considering an offer. The notice tells residents they can compete to buy the park and must form or identify a single tenants committee within 15 days. The committee may request financial information during that window, and a copy of the notice goes to Housing and Community Services. This is a right to compete, not a guaranteed right to match.
Where to get help in Oregon
The Manufactured and Marina Communities Resource Center at Oregon Housing and Community Services runs a hotline at 1-800-453-5511, option 2. It also coordinates park mediation through community dispute resolution centers, offered at no cost. For a rent increase that looks too high, start there, and keep a copy of the notice and your rental agreement.
Frequently Asked Questions
Is the 6 percent cap the same for every Oregon park?
No. ORS 90.324(1)(a) sets six percent only for month-to-month space tenancies in facilities with more than 30 spaces. Smaller parks use the apartment formula of the lesser of 10 percent or seven percent plus CPI.
Can my Oregon park evict me so it can rent my space to someone else?
Not on a no-cause notice. ORS 90.427(13) makes the general no-cause termination rules inapplicable to space tenancies, so the park needs a statutory ground such as unpaid rent under ORS 90.394, a violation under ORS 90.630, or a closure under ORS 90.645.
How fast must the park answer my buyer’s application?
Within seven days of receiving a complete and accurate application, under ORS 90.680(10). If you didn’t give the park the 10 days’ advance notice of the sale, it gets 10 days instead. The parties can agree to more time.
Do I still get the closure payment if I abandon my home?
Yes. ORS 90.645(4) says the landlord must pay the full amount whether the tenant relocates or abandons the dwelling, except in the subdivision-conversion situations described in ORS 90.645(2).
What does a tenants committee actually get?
Meetings with management up to twice a year on non-rent concerns, a written good-faith response within 60 days, and access to informal dispute resolution under ORS 90.769 if the landlord refuses. Those rights come from ORS 90.600(8).
