The San Francisco City Planning Commission convened on July 4, 2025, to discuss a proposed vertical addition to a residential property located at 415 Grafton Avenue. The meeting focused on the implications of the addition for neighboring properties, particularly concerning light, air, and privacy.

The applicant presented an updated solar study indicating that the proposed addition would allow for approximately one additional minute of direct sunlight into adjacent windows. Despite previous communications with the architect regarding potential modifications to the plans, the applicant reported a lack of response until after a discretionary review hearing held on March 31, 2025, where the commission unanimously declined the request for changes, citing no extraordinary circumstances.

The applicant emphasized the importance of maintaining as much roof space as possible for future solar panel installation, aligning with sustainability goals. The proposed addition, which includes two bedrooms and two bathrooms, adheres to the zoning height limit of 35 feet and features a sloped roof design. The applicant noted that the existing house is built directly on the property line, and any setback would significantly reduce livable space.

The Planning Department, represented by Tina Tam, confirmed that the project complies with the planning code and residential design guidelines. The department recommended denying an appeal from the adjacent neighbor, Evelyn Mau, who raised concerns about light and privacy impacts. The commission noted that the proposed addition is modest in size and that the separation between the two properties is sufficient to mitigate privacy issues.

During the meeting, commissioners engaged in discussions regarding the historical context of the properties and the potential for further development. It was noted that the appellant's property is a double lot, which provides ample space and light, further supporting the planning department's stance on the addition's minimal impact.

In conclusion, the commission's discussions highlighted the balance between individual property rights and community standards, with the proposed addition deemed compliant with existing regulations. The next steps will involve finalizing the permit process, allowing the applicant to proceed with the construction of the vertical addition.
