A Georgist LVT would fix that is short order. Start making owners pay compensation for keeping a valuable space empty and crumbling, and you'll see them step to it pretty quickly or sell it to someone who does.
Though I am pro-LVT, I don't think this will help in the current situation.
The owner, the bank, and the city all wish to maintain the illusion that a $10M building from 2010 is still worth at least $10M today, even vacant. No party wishes to realize the loss in value. Occasionally, the city may try to punish vacancy with a tax, which is still about additional revenue and not about realizing diminished value.
If it's empty and crumbling, I doubt it's all that valuable to be repurposed for housing or anything else. I did note the other day in the very small downtown of a nearby minor city that the the ancient travel agent is now a party supply store. But, really, there's not a lot in that downtown.
