San Francisco supervisors debate quadplex legislation to tackle housing affordability crisis

The San Francisco County government meeting held on July 4, 2025, focused on discussions surrounding housing legislation, particularly the proposed quadplex and sixplex developments aimed at increasing housing production in low-density neighborhoods. The meeting began with Supervisor Mandelmann expressing gratitude for the chair's acknowledgment of the significance of the rezoning legislation. He emphasized the limited on-the-ground impact of the proposed changes but highlighted the value of allowing six units on corner lots and simplifying the process for developing fourplexes and sixplexes.

Mandelmann raised concerns about amendments that could restrict the legislation's effectiveness, particularly those limiting condo creation to current residents. He argued that such restrictions could hinder the potential for new housing units, which are crucial in addressing the city's housing crisis.

Supervisor Marr followed, reiterating the importance of the quadplex proposals as a strategy to create new housing opportunities, especially in neighborhoods that have seen rising unaffordability and displacement of working families. He presented a set of amendments aimed at incentivizing affordability and ensuring that new developments meet the needs of families, particularly in BIPOC communities. These amendments included defining bonus units, requiring affordability agreements, and ensuring that new units are family-sized.

Marr also proposed measures to prevent speculation and displacement, such as requiring replacement units for demolished rent-controlled properties and prohibiting short-term rentals on bonus dwelling units. He emphasized the need for a balanced approach that supports housing production while protecting vulnerable communities.

The meeting concluded with a call for further consideration of the proposed amendments, aiming to strengthen the legislation and address the pressing housing affordability crisis in San Francisco. The discussions underscored the ongoing challenges of balancing development with community needs and the importance of collaborative efforts among supervisors to create effective housing policies.
