City of LA under the visionary leadership of their Building Department and
the SEAOSC implemented a URM retrofit program in early 80's for URM's. This
resulted in almost 6000 structures being retrofitted to the criteria that
eventually made its way to the Uniform Code of Building Conservation. Since
then many other cities in California, such as San Jose, have implemented
similar programs that have brought many of these unsafe buildings to some
reasonable level of safety. (I agree with you that bringing existing
buildings to full current code compliance is a daunting task)
Anyway, maybe other states will follow California's leadership, (as they do
in many other things!) and implement retrofit programs.

Seattle does not require retrofit of any buildings unless the owner
making other changes or improvements to the building. There are
triggers in the Seattle amendments to the UBC that will require the
to meet the current code requirements. My opinion is that this is
awkward provision since it is very difficult to show that the
actually brought the old building into full compliance with current
There seems to always be a compromise of some sort that is reached
building official with respect to the scope of the upgrades
Outside of Seattle, I am not aware of any requirements other than
provisions reagarding unsafe conditions.
This latest event may precipitate some changes.
