1340-1342 12th Ave, San Francisco, CA 94122

The property at 1340-1342 12th Avenue, a 3-unit multi-family residential building constructed in 1902 in San Francisco's Inner Sunset neighborhood, has experienced several significant maintenance and safety issues in recent years. Most notably, between 2020-2021, the building faced multiple serious problems including water intrusion, mold, dry rot, and rodent infestations, as documented in multiple tenant complaints. A major incident occurred in September 2020 when washing machine flooding caused extensive water damage throughout the building. In response to violation notices, the property underwent various repairs, including the replacement of footings, slabs, and area drains in late 2021, though these were initially triggered by issues documented in a November 2021 complaint about water intrusion and mold problems.

The building has also required multiple water heater installations and replacements over the years, with the most recent plumbing work in 2022 involving new drains and catch basins. The property's maintenance history shows recurring issues with building systems and infrastructure, including electrical upgrades (new service, meters, and panel installed in 2005), various plumbing repairs, and structural work. The building has experienced multiple tenant-reported issues between 2019-2023, including problems with stairs, weatherproofing, floor coverings, and hazardous conditions. A tenant buyout occurred in May 2022 for $25,000, involving one tenant.

Numerous violations related to safety and maintenance standards were recorded and subsequently addressed, including fire safety concerns and security requirements. Recent 311 calls between 2019-2024 primarily relate to parking enforcement and general maintenance issues, with no significant building-specific concerns reported in the latest calls. The building's most critical issues appear to have been addressed through various permits and repairs, though the frequency of violations and complaints over recent years suggests ongoing maintenance challenges. The property has undergone multiple systems upgrades, including electrical, plumbing, and structural improvements, in response to both tenant complaints and official violation notices. While many of the historical violations have been resolved, the pattern of recurring maintenance issues suggests that regular upkeep and prompt attention to resident concerns has been an ongoing requirement for this building.
