434-436 Union St, San Francisco, CA 94133

This three-unit multi-family residential building, located at 434-436 Union Street in Telegraph Hill and built in 1907, has experienced several significant events throughout its history. Most recently, in May 2023, dry rot repairs were initiated for steps leading to the terrace back yard. The property has a notable history of unauthorized unit conversions, with an illegal ground floor dwelling unit conversion in 2008 prompting multiple violations regarding safety features such as smoke detectors, emergency egress, and fire resistant materials.

This unit conversion was ultimately addressed in 2009, though similar complaints about basement storage units being rented as illegal apartments were filed in 2008. The building underwent several improvements in 2003, including bathroom remodeling and electrical upgrades in apartment B, plus structural modifications on the third floor. The property has a documented history of addressing safety concerns, including routine inspections in 2005 that revealed various fire safety issues, all of which were subsequently abated.

There was also a period of unauthorized short-term rental activity reported in 2018, leading to a cease and desist directive from the Office of Short-Term Rentals. Recent maintenance activity includes ongoing attention to exterior maintenance, as evidenced by multiple 311 calls in early 2024 regarding garbage and debris removal. The building's repair history shows ongoing maintenance attention, with permits indicating both routine upkeep and responses to specific violations. Additionally, there were two uncategorized fire complaints in 2012 and 2014, both of which were promptly resolved with conditions corrected.
