ORS 90.505–90.850 · Marina space tenancies
Marina & floating-home tenancies in Oregon
If you own a floating home and rent the space under it in an Oregon marina, special landlord–tenant rules apply. Those rules sit in ORS Chapter 90 — the same chapter that covers manufactured dwelling parks — and they are stronger than ordinary boat-slip arrangements.
This page is only for people who own the floating home and rent the moorage space in a statutory marina facility. It does not apply to apartment rentals. It explains who the facility package covers, documents and rent rules, how tenancies can end, sale-in-place, and marina closure. Educational only — not legal advice. Last checked against official ORS Chapter 90 and 2026 DAS rent-cap figures (September 2026).
Who is covered
Who these rules cover (and who they don’t)
Oregon’s strongest marina protections apply when all of the following are true (ORS 90.120(3)): you own the floating home; you rent the space (moorage); and that space is in a facility. A “facility” is a manufactured dwelling park or a marina (ORS 90.100(16)). A marina is a moorage of contiguous dwelling units that may be transferred as a single unit, owned by one person, where four or more floating homes are secured, and the primary purpose is to rent space (ORS 90.100(30)).
A floating home has the meaning in ORS 90.100(20), which points to ORS 830.700: a moored structure secured to a pier or pilings and used primarily as a domicile, not as a boat. Occasional use for transport does not automatically take you out of that definition if the structure is still primarily your home (see Ramsum v. Woldridge, 222 Or App 109, 192 P3d 851 (2008)).
If you meet this test, the manufactured dwelling park and marina package in ORS 90.505–90.850 generally applies, along with other Chapter 90 provisions that cover facilities.
Recreational boat slips
Renting a recreational boat slip is not the same as a floating-home marina tenancy
Many boaters assume they have the same rights as floating-home owners in a statutory marina. Often they do not. Recreational vehicles are excluded from the facility package, and a vessel that is not primarily a domicile floating home — or moorage that is not a marina with four or more floating homes — may not be covered by ORS 90.120(3). Confirm your classification before you rely on marina-tenant rules.
Arrangements this page does not cover
You rent both the home and the space
That arrangement is classified under general Chapter 90 rules, not the full marina facility package (ORS 90.120(5)(b)). OSTA public guidance on this site is for space tenancies only. Talk with the helpline or an attorney.
You own the home but the space is not in a facility
If the space is outside a statutory marina or park, the ORS 90.505–90.850 package does not apply (ORS 90.120(5)(c)). Different notice rules may apply. This hub does not give advice for those tenancies — start with classification help from OSTA or a lawyer.
