Senate Bill 423 streamlines San Francisco's housing approval process by reducing the timeline for residential developments from about two years to six months. Building on SB 35, it mandates ministerial approval for qualifying projects and expands streamlined approvals to include market-rate housing. The legislation requires the city to meet state housing goals with annual assessments, though challenges like high construction costs and interest rates remain.

Senate Bill 423, authored by State Senator Scott Wiener, streamlines the approval process for housing projects in San Francisco and 18 other Bay Area cities. This new law bypasses lengthy discretionary reviews, expediting approvals for residential developments that include affordable housing components.

SB 9 enables San Francisco Bay Area property owners to transform single-family lots into multi-unit properties, significantly boosting property value, generating rental income, and reducing development costs. The law streamlines approvals, making it easier and more financially viable to develop new housing units.
