^ I've heard of some new parking podiums and garages being designed with slightly higher ceilings and less sloped/more flat floorplates to make a residential conversion much easier in a few decades. That spiral ramp on Trump, for example, can be demolished leaving perfectly flat floorplates ready for a conversion.

I've never seen a detailed estimate on how much it costs per SF to do a conversion like this, there's only a handful of cases where this has actually been done, and usually they are older garages from the mid-century era and each one is unique.

This seems like it would be harder for a lot of downtown highrises, if you're squeezing a multi-story garage onto a typical tight River North site then your entire garage is gonna be sloped.
