1315 Lyon St, San Francisco, CA 94115

The property at 1315 Lyon Street is a one-story, two-unit multi-family residential building located in Lower Pacific Heights, constructed in 1890 and classified as Flats & Duplex under the Wing Family Trust ownership. The building's most significant historical issue occurred in 2004 when multiple violations were recorded regarding an unauthorized conversion from a single-family dwelling to two units, with an additional ground floor unit constructed without proper planning or building department approval.

These violations, which also included improper roof drainage, went through various enforcement stages including Notices of Violation and a Director's Hearing on April 8, 2014, before being officially abated on June 30, 2014. More recent concerns primarily relate to exterior maintenance issues, with multiple 311 calls in 2024 regarding garbage and debris, including an open case for a collapsed sidewalk logged in July 2024.

Other recorded incidents include a 2023 Department of Public Health environmental health complaint, graffiti issues in 2019 and 2011, a missing side sewer vent cover in 2018, and various street cleaning matters. The building's planning records confirm the resolution of the 2004 violations, with a Letter of Determination issued regarding the number of units. While the 2004 conversion issues were ultimately resolved, the property has experienced ongoing maintenance challenges in more recent years, particularly concerning public sidewalk conditions and waste management.
