The only place I'm aware of that bans new parking garages in the US is Manhattan, which has a general parking cap; but providing enough spaces for the actual car travel demand to Manhattan would necessitate leveling the whole island and then some, so the policy is there to get people to stop driving to a narrow, congested island.
If high cost is the issue, it seems like people are complaining about lack of parking but don't want it enough to pay the real, unsubsidized price. So why should everyone else pay for them?
That's exactly what it is. The normalization of "free" street parking does a lot of damage here.
Seems unreasonably high.

For a whole parking garage you need many large I-beams, tons of concrete, frequently elevators are added, etc. Not surprising builders opt out of including them when they can.
Autonomous vehicles will reduce the need to park. Eventually.
I have a friend who inherited three such lots in downtown ($$$) and he lives very comfortably off just that revenue because their old assessments totaled under a million so they never got reassessed (though the rules have become far less generous with Prop 19).
This has all been more-or-leas fine, with residential prices factoring in parking, and multi-tenant developments pulling in density via car stackers and the like. Oh, and a pretty functional transit system, of course.
