Sad anytime a life is lost.  But you have to wonder if there is capital enough in Portland to replace rental units as fast as they appear to be able to burn them in that area.  It is one or more,  almost daily,  and usually multiple  units destroyed by one blaze.  And this at a time when there are few smokers as opposed to say,  forty years ago,  when smoke detectors were few, the building codes less restrictive,  tens of millions fewer dollars spent in awareness campaigns.   The old expression of "beating it like a rented mule" pretty much must explain rental properties.  Renters are not invested and don't have any feelings or inklings of ownership in where they live.  When this one gets too ruined,  stained,  stinky,  unkempt,  unlivable,  just move to another newer and cleaner place.
