Upzoning Under SB 50: The Influence of Local Conditions on the Potential for New Supply


In this brief, we explore what might happen were SB 50 to pass by taking a detailed look at local market conditions in four case study neighborhoods. Local context shapes financial and physical feasibility. When SB 827, the predecessor to SB 50, was under consideration, estimates of its impact on new housing supply were optimistic.
