120-122 Langton St, San Francisco, CA 94103

The two-unit residential building at 120-122 Langton Street in the South of Market neighborhood, owned by Ho Diem, has a history of significant maintenance and safety issues dating back to its construction in 1906. Most recently, the property underwent several improvements in 2019, including interior door replacements, kitchen renovations, and entry stair safety upgrades costing approximately $30,000, with associated plumbing and electrical work. The building faced numerous violations in 2017, including lead paint concerns, water damage, mold, and plumbing issues, all of which were officially abated by July 2017.

Previous major work included window replacements in 2017 to comply with a notice of violation, and in 2013, the removal of an illegal unit from the garage and associated kitchen facilities. The property has experienced recurring fire safety concerns, with violations noted for sprinkler systems, standpipe systems, and fire extinguishers between 2018 and 2024, most recently involving missing caps on standpipes at the adjacent 310 07th Street address in July 2024. Historical records show the building suffered fire damage in 1988, requiring substantial repairs and system replacements.

Maintenance issues have persisted over the years, including multiple 311 calls regarding plumbing problems, leaks, and the presence of mold and dilapidated windows. Recent 311 calls from 2024 indicate ongoing neighborhood maintenance challenges, including noise complaints and sidewalk blockages. While many of the historical violations and complaints have been addressed and abated, the building's maintenance history suggests an ongoing need for attentive property management, particularly regarding building systems and fire safety compliance.
