The California legislature approved Senate Bill 35 in 2017, with goals to speed up an onerous permitting process and remove traditional obstructions to planning and building multi-family housing projects.

The law is set to sunset in 2026, but a proposed bill, SB 423, would extend and amend the process created by SB 35. Five years, or halfway, into the law’s existing ten-year window, the Terner Center for Housing at the University of California, Berkeley provides an analysis of SB 35’s accomplishments so far. The analysis catalogues and maps 156 projects. Here is how the article explains the findings of the analysis.

Five years in, we find that SB 35 has become the streamlining method of choice among affordable housing developers, who report that the law has made the approval process for new multifamily infill development faster and more certain. Between 2018 and 2021, 156 projects were approved for streamlining or had a pending application, comprising over 18,000 new proposed housing units. Most of these projects are 100 percent affordable developments ( in which all units are designated for households with lower incomes) and most of the projects are located in either the Bay Area or Los Angeles regions.

The source article, linked below, includes an interactive map and an .xlsx file with the list of 156 CB 35 projects. The full report, written by Shazia Manji and Ryan Finnigan, is also available online.
