We are building a ton of apartment buildings, but most of it is replacing light commercial, industrial or virgin lots. Adding duplex, triplex, and quadplex housing allows further density in established residential neighborhoods where you have no political chance of putting a 6 story apartment building. Additionally, duplex units can be sold, making a greater number of residents into invested homeowners.
