642 Alvarado St, San Francisco, CA 94114

642 Alvarado Street is a 34-unit, 3-story multi-family residential building constructed in 1963, currently owned by 642 Alvarado I7 LP. The property is undergoing significant renovations, including the addition of ADUs (Accessory Dwelling Units), with recent permits showing work on sound systems, fire safety systems, and various unit improvements between 2022-2024. A major soft-story strengthening project was completed in September 2023, improving the building's seismic safety.

The property has experienced recurring fire safety maintenance issues, with violations noted for alarm systems in 2015, 2017, 2018, 2019, and most recently in November 2023 for sleeping area requirements. Building maintenance history shows attention to various unit updates, including laundry installations and window replacements, particularly in units 101, 206, and 207. The building has faced several significant structural and maintenance challenges over the years, including concerns about support beams in 2011-2012, balcony railing issues in 2015, and water pipe concerns in 2014.

Fire safety compliance has been an ongoing focus, with multiple violations addressing alarm systems and extinguisher maintenance between 2008 and 2023. Recent construction activity includes comprehensive improvements to all nine new units' wiring in December 2023, installation of new shower pans, and updates to the building's plumbing and fire safety systems. The property had multiple building violations in 2002-2017 related to fire safety, structural maintenance, and garbage management, all of which were eventually abated. While recent permits show substantial investment in building improvements, including the installation of a new boiler system, water service lines, and fire sprinkler systems, the property has a history of deferred maintenance issues that have gradually been addressed through ongoing renovations.
