Dezoning most American cities would be quite a good thing. We massively subsidize parking thanks to our zoning requiring parking minimums (such that buildings are only able to rent parking for low $0.xx/sqft a month, versus $x/sqft a month for housing in the same building), and we also block or kneecap larger buildings by restricting their size and the number of units within them.

These restrictions (nearly all carried out as zoning) could easily be removed and allow a wave of development to occur, lowering housing costs and keeping many people from ending up homeless in the first place.
