Security deposits
Cap
No statutory cap
Return clock
31 days after the tenancy ends
Oregon does not cap how large a residential security deposit may be. Unused deposit plus a written accounting is generally due within 31 days (Or. Rev. Stat. § 90.300). Statewide just-cause and rent-increase limits still apply to many tenancies.
A tenant may end a month-to-month tenancy with 30 days’ notice. After the statutory occupancy period, a landlord generally needs a qualifying reason and longer notice (Or. Rev. Stat. § 90.427).
Except in an emergency, the landlord must give at least 24 hours’ notice before entering (Or. Rev. Stat. § 90.322).
Oregon generally requires at least 90 days’ written notice before a rent increase takes effect (Or. Rev. Stat. §§ 90.323, 90.600). Statewide rent-increase limits may also cap the amount. Portland can add local rules.
Oregon residential leases commonly need these statewide disclosures. The lease generator adds them when your answers trigger them.
Just cause and rent increase
After the statutory occupancy period, ending a tenancy or skipping a renewal generally requires a listed cause. Statewide rent-increase limits may also apply. Portland adds local rules.
These Oregon cities often have rent-control, just-cause, or relocation rules on top of state law. Confirm the ordinance before you raise rent or decline to renew.
