1519 Hudson Ave, San Francisco, CA 94124

1519 Hudson Avenue is a two-story, two-unit multi-family residential building located in the Bayview neighborhood, owned by Young Siu Ping and constructed in 1900. The property has experienced significant and ongoing issues related to unauthorized modifications and safety compliance, most notably involving the addition of unauthorized bathrooms and kitchen facilities.

In 2024, permits were issued to address violations from early 2023, including the removal of an unpermitted basement bathroom, restoration of an unauthorized kitchen to its original living room configuration, and merging of two bedrooms in unit B. These modifications were necessary to comply with an active building violation from February 2023 that documented several unauthorized improvements, including an unauthorized fourth bathroom, additional kitchen, and security gate that blocked shared egress between units. The building has a history of maintenance issues and neighbor complaints dating back several decades, including termite damage repair in 1989 and stair repairs in 2001.

Recent complaints from 2023-2024 have centered around shared infrastructure problems, including a leaking shared sewer line, unauthorized modifications to emergency exits, and blocking of common areas, particularly affecting the neighboring property at 1521 Hudson Avenue. These ongoing issues have resulted in multiple inspection requests and violation notices, with recent permits issued in October 2024 (both plumbing and electrical) indicating work to address these violations is actively ongoing. The property has also been subject to various planning records, including attempts to obtain variances for unpermitted modifications, though these requests have been marked as closed or withdrawn.
