1609 Vallejo St, San Francisco, CA 94109

The four-story, eight-unit multi-family residential building at 1609 Vallejo Street in Pacific Heights, owned by Osa Associates IV LLC, has been maintained and updated since its 1900 construction. Significant recent work includes earthquake safety compliance efforts in 2020 (after initially being cited in 2018), repairs following a car crash incident in 2018, and a completed $9,000 repair project in 2018.

The building has undergone several important maintenance activities, including dryrot repairs in 2015 and reroofing in 2008. Historical inspection records show various issues were addressed, including fire escape maintenance in 2009, sewer problems in 2002, and routine inspections of common areas. The property has experienced multiple fire safety-related incidents over the years, though none resulted in injuries, including carbon monoxide detector activations, cooking-related incidents, and occasional alarm system malfunctions.

While there are no active violations on record, the building has previously faced challenges such as a soft-story retrofit requirement, which appears to have been resolved as of 2020. Recent 311 calls (2023-2025) have primarily concerned exterior maintenance issues such as garbage management and sidewalk cleaning, though these are typical urban management concerns unrelated to building safety or habitability. The building's commercial space has seen various adaptations over the years, including the establishment of a beauty salon in 2005 and restaurant-related permits, most recently in connection with a Type 41 ABC license for restaurant use.
