Burlingame, one of the wealthiest cities in the Bay Area, has a decent mix of multifamily and single family housing. The last time I checked, it was about 50/50 renters owners. Given the exorbitant prices to buy a house there, the rents are somewhat reasonable (quite a bit cheaper than SF, starting at about $1800 for a one bedroom). In spite of this, it still is very racially homogenous (very few African Americans or Latinos). Additionally, the schools tend to be mostly homeowner's children -- very few families rent there in order to give their children access into the top ranked public schools. Based on the real world example of Burlingame, it's not clear that changing the zoning rules will lead to the outcomes that the study authors hope for.
