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.
If you let your property go empty and crumble, the Land Value Tax is there to provide the incentive for you to either fix up the property and actually use it, or sell it to someone who will.
If the land is worth less than nothing (contaminated etc) then there should have been a bond involved to ensure the clean up fee was collected.
In addition to what others said, in this case the land is obviously not worth very much, and thus the taxes are also minuscule.
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.
