Texas doesn't require inspections on parking structures. It was a thirty year old, beam supported slab deck that was supported by columns, in some manner, the columns walked out and the deck dropped. It was ruled "an act of God" and blamed on a combination of heavy spring rains and a dry summer. It was a dodgy structure before this happened, you could feel it wobble when heavier cars drove across it and when it rained, it would leak through the slabs onto the cars parked below. I parked in a spot that was safe from the collapse on most days, but got there late that day and just took what was available, oops.
