Supervisor Mandelmann proposes limits on monster homes in San Francisco districts

A significant amendment aimed at curbing the rise of "monster homes" in San Francisco's District 8 was discussed at a recent city planning commission meeting. The proposed legislation, championed by Supervisor Mandelmann, seeks to sunset conditional use requirements for the Corona Heights and Central Neighborhoods Special Use Districts (SUDs) by the end of 2024. This change would limit the size of new residential units to 3,000 square feet, with modest expansions allowed for existing homes.

Adam Tonksva, an aide to Supervisor Mandelmann, emphasized the need for this amendment to address the ongoing issue of oversized homes that threaten the city's housing goals of affordability and density. He noted that the current conditional use controls are under scrutiny due to the upcoming implementation of SB 423, which could complicate housing approvals. The proposed changes aim to replace subjective requirements with objective standards, streamlining the approval process for new housing projects.

The planning staff recommended modifications to the amendment, suggesting an increase in the maximum unit size from 3,000 to 3,500 square feet and allowing a 20% increase in home size, up from the current 15%. These adjustments are intended to facilitate modest expansions while still addressing the concerns surrounding large residential developments.

Public comments reflected a mix of support and opposition. Advocates, including local community leaders, argued that the amendments would promote affordable housing and preserve the character of neighborhoods. Critics, however, raised concerns about the arbitrary nature of size limitations and the potential impact on housing diversity.

As the commission prepares to move forward, the outcome of this legislation could significantly shape the future of residential development in San Francisco, balancing the need for housing with community preservation. The next steps will involve further discussions and potential revisions before the proposal is sent back to the Board for final approval.
