In order to understand how higher inclusionary housing requirements affects the feasibility of new market-rate housing development, the Controller's Office contracted with Blue Sky Consulting Group to statistically model the factors that affect the probability of housing development in San Francisco. This data underlies the model reported in our preliminary report. An overview of the statistical analysis is provided in main section of the report, with more details provided in the Appendix.

Subject to Planning Code Section 415 (http://bit.ly/1ag0AmP), developments of 10 or more units fall under the City's Inclusionary Affordable Housing Program. Data on residential projects are collected through the lifecycle of the projects by the Planning Department and the Department of Building Inspection. On a quarterly basis, the Mayor's Office of Housing and Community Development works with Planning to produce a list for tracking and monitoring of these projects. This dataset is as of December 31, 2021.
