156 Parnassus Ave, San Francisco, CA 94117

Located at 156 Parnassus Avenue, this 6-unit, 2-story multi-family residential building constructed in 1924 has undergone several significant improvements and maintenance work over the years. Most notably, the building completed a mandatory soft-story seismic retrofit in 2016-2017 (Tier 3), which included the installation of new furnaces, water heaters, and flue pipes, with a total investment of approximately $90,000. The property has seen consistent maintenance of major systems, including a 200-amp electrical service upgrade and comprehensive plumbing work in 2012, though recent concerns about gas service placement below the slab were documented in 2017.

The building has experienced persistent sewer system challenges, with multiple complaints about flooding and backups documented in 2024, including incidents on November 14 and 11. These recent plumbing issues appear to be a continuing concern, as evidenced by multiple 311 calls to the Public Utilities Commission in November 2024. Historical records show the property has addressed various maintenance issues over time, including kitchen and bathroom renovations in 2012, roof work in 1996-1999, and stair repairs in 1996 and 2005.

While there were several violations related to lead paint hazards, stair repairs, and plumbing issues in 2005-2011, these were resolved by January 2006. The building's ownership by Devpac LLC has maintained an active record of compliance and improvements, including a recent Verizon wireless equipment installation in 2023. The most recent routine inspection by Housing Inspection Services was recorded in February 2023 and remains active.
