The San Francisco Planning Commission convened on July 4, 2025, to discuss a significant legislative proposal aimed at addressing unauthorized dwelling units (UDUs) in the city. The proposed ordinance, sponsored by Supervisor Melgar, seeks to create a conditional use authorization (CUA) exemption for the removal of UDUs that have not been rented for at least ten years.

Michael Farah from Supervisor Melgar's office presented the legislation, highlighting its origin in constituent concerns and the collaborative effort with other supervisors to refine the proposal. The ordinance stipulates that property owners must reside in the primary unit and commit to living there for a minimum of three years after the UDU's removal. Additionally, property owners would need to enter a regulatory agreement that subjects the resulting single-family home to rent control provisions.

The ordinance also proposes exemptions for UDUs that do not meet specific planning and housing code requirements, such as open space or minimum floor-to-ceiling height. These exemptions would extend to multifamily buildings as well. Furthermore, the legislation aims to streamline the process for families looking to adapt their homes for growing households, including aging relatives.

During the meeting, public comments were received, with suggestions for modifications to the ordinance. One recommendation urged that property owners declare under penalty of perjury that the UDU has not been occupied in the past decade, while another suggested requiring property ownership for at least one year to prevent speculative development.

Staff members expressed support for the ordinance with modifications, emphasizing its potential to facilitate housing adjustments for families and reduce procedural barriers. The commission members generally voiced their support for the legislation, recognizing its importance in accommodating multi-generational households in San Francisco.

As the discussion progressed, the commission acknowledged the need for further dialogue regarding the proposed modifications before moving forward. The outcome of this meeting could significantly impact housing policy in San Francisco, particularly for families seeking to adapt their living situations in a city facing ongoing housing challenges.
