It’s a problem that isn’t going away: the so-called “affordable” housing we’re building in many cities—by which we mean publicly subsidized housing that’s dedicated to low- and moderate-income households—is so expensive to build that we’ll never be able to build enough of it to make a dent in the housing affordability problem
. . . . More broadly, the case has been made that much publicly subsidized affordable housing costs much more to build than market rate housing. Private developers are able to build new multi-family housing at far lower costs. One local builder has constructed new one-bedroom apartments in Portland at cost of less than $100,000 a unit, albeit with fewer amenities and in less central locations than most publicly supported projects. In Portland, local private developer Rob Justus has proposed to build 300 apartments and sell them to the city for $100,000 each on a turn-key basis to be operated as affordable housing. Another possible cost savings measure: off-site construction. The University of California, Berkeley’s Terner Center has a report that explores the possibility for pre-fabricated, off-site construction to reduce construction costs.
