Commission approves certificate of appropriateness for Clock Tower Building renovations

The San Francisco Planning Commission convened on July 4, 2025, to discuss a significant application for a certificate of appropriateness concerning the historic Clock Tower Building at 461 Second Street. The meeting began with Commissioner Nargis Warren recusing herself from the discussion due to a conflict of interest related to her firm’s involvement with the project. The motion to recuse was unanimously approved by the commission.

Monica Giacomucci, a staff member from the planning department, presented the details of the application. The Clock Tower Building, constructed in 1907 for the Schmidt Lithograph Company, is a notable contributor to the South End landmark district. The building has undergone various changes over the years, including the addition of the clock tower in 1920 and modifications to its exterior in the 1960s.

The proposed project seeks to replace the existing painted metal roofing system with a new one that matches the original in material and color. However, the new panels will be smaller, resulting in a change to the building's appearance. This alteration disqualifies the project from an administrative certificate of appropriateness, which typically allows for straightforward approvals when materials are replaced in kind.

Additionally, the project includes the replacement of eight windows on the south side of the building. Initially described incorrectly in project plans, the new windows will be 2 over 2 aluminum sash windows, matching the existing style.

If approved, the planning department will update the staff report to reflect the corrected scope of work. The commission's decision on this application will have implications for the preservation of the building's historical integrity while accommodating necessary updates. The outcome of this meeting underscores the ongoing efforts to balance modernization with the preservation of San Francisco's architectural heritage.
