Multifamily real estate development is vital to addressing the nation’s housing affordability crisis. Our research examines barriers that smaller and newer housing development firms face when growing their businesses—such as limited preconstruction capital and overcoming zoning or other regulatory hurdles. Our research also explores solutions across public, philanthropic, and private sectors. And we analyze multifamily housing construction and rehabilitation landscapes across cities in the US, exploring trends in leadership, firm size, and firm type.
