418-422 Presidio Ave, San Francisco, CA 94115

The three-story multi-family residential building at 418-422 Presidio Avenue, located in Pacific Heights, is a 4-unit structure built in 1900 that has undergone several significant maintenance and upgrade projects over the years. Most notably, as of January 2025, the building is undergoing substantial work including electrical system upgrades (new subpanels, wiring, outlets, switches, and fixtures across all floors), plumbing improvements (replacement of sinks, faucets, toilets, and repair of mainline sewer issues), and structural maintenance (replacement of rotted wood at the rear staircase) with a combined cost of $82,500.

Previous major work included a kitchen and bathroom remodel in 2019 ($35,000) and foundation repairs in 2010 ($55,000). The building has experienced some maintenance challenges over its history, particularly with its sewer system, as evidenced by multiple 311 calls regarding sewage backups in 2009-2017, including issues with catch basins and manholes.

A significant cluster of building violations was documented in December 2004, related to fire safety and emergency exit requirements, though these were all abated by January 2005. Earlier complaints include a 1994 incident regarding unsafe back steps and a 1998 report of inadequate heat and window sealing. The property's maintenance history shows regular attention to infrastructure systems, with multiple permits issued for plumbing and electrical work between 2009 and 2025, indicating ongoing efforts to maintain and upgrade the building's systems.
