168-170 Langton St, San Francisco, CA 94103

The property at 168-170 Langton Street is a two-story, three-unit multi-family residential building constructed in 1906, currently owned by the Li-wen Chia Living Trust. The building underwent significant modifications between 2007-2012 to legalize and improve its third dwelling unit, including the installation of a fire sprinkler system, kitchen modifications, and electrical system upgrades. The third unit conversion was completed in 2012 at a cost of $5,700 for the sprinkler system alone, with additional electrical work valued at $2,500.

During this period, several building permits and inspections were processed, indicating active code compliance efforts, though there were some initial concerns about possible illegal units, electrical issues, and improper occupancy in 2010 which were ultimately resolved. More recent records from 2024 show several fire safety concerns, including multiple fire code violations and blocked exits, though some issues were corrected promptly. The building's management has faced multiple fire safety inspections since 2018, with varying outcomes including both "No Merit" and "Condition Corrected" findings.

Historical complaints from 2018-2019 regarding structural maintenance and safety equipment were addressed, and a parking variance was obtained to legalize the third unit. The property has experienced recurring issues with garbage and debris in the surrounding area as documented in 311 calls throughout 2023-2024, though this relates to the exterior rather than interior conditions of the building itself. Recent fire safety violations (September 2024) regarding an ERRCS permit suggest ongoing compliance challenges, though the building's core unit legalization and safety systems appear to be generally maintained based on historical permit and inspection records.
