30 De Long St, San Francisco, CA 94112

The two-unit residential building at 30 De Long Street in San Francisco's Outer Mission neighborhood is a two-story flats and duplex structure built in 1908, currently owned by Scott Mark S. The property has experienced several notable events over the past decades, with the most significant structural issues occurring in 2012 when unauthorized demolition and partial re-framing of rear egress stairs resulted in a building violation that required correction. This situation was resolved through two building permits (totaling $7,001 in repairs) that completed the repair/replacement of three landings and a significant portion of the stairway system.

Additional improvements during this period included a gas houseline extension completed in October 2012. More recent concerns at the property have primarily involved exterior maintenance and safety issues. In 2021, there were recorded fire code violations, while earlier records from 2014 noted problems with weeds and grass that were determined to have no merit.

The past few months (from December 2024 to January 2025) have seen multiple reports of garbage and debris issues on or near the property, with at least eight such incidents recorded through 311 calls, most of which have been resolved. Additionally, there have been recent concerns about an overgrown tree (January 2025) and parking enforcement matters, though these are relatively minor compared to the building's historical structural issues. It's worth noting that a tenant buyout occurred in August 2015 at an adjacent property (22 De Long Street), involving four tenants and a buyout amount of $18,000.
