Gary, I believe it is possible that, for non-residential properties, a lease can be written which does not have the normal protections you cite that are part of Oregon law for residential property.  Even in the storage locker situations, the owner has to advertise  in the paper before the he opens the unit and sells the contents.  I would be curious to see the terms of the lease. It is hard to believe this is a purely civil matter, but I think it is possible if the tenant agreed in writing to allow the owner to enter and take personal property in the event that rent was not paid.
