cost per unit actually goes up as buildings get larger, so it really depends on the market. i don’t really know any developers who actively oppose upzoning in my region, but the SFH builders I think have an easier and more lucrative job than the ones doing urban infill.

Construction cost per unit goes up a little, but land cost per unit goes down a lot, because you buy the same plot of land and put N times more units on it.
