445-449 Lombard St, San Francisco, CA 94133

The three-unit multi-family residential building at 445-449 Lombard Street in Telegraph Hill, owned by Frank Salvatore Viollis, was constructed in 1910 and consists of two stories. The property has undergone several significant improvements over the past two decades, with the most recent major work being the replacement of two double-hung rear windows in 2016. The building's maintenance history shows consistent attention to window upgrades, with multiple window replacements documented between 2003 and 2005, transitioning from various materials (aluminum, wood) to paintable wood composite.

Other notable improvements include a roof replacement in 2003, installation of a direct vent wall heater in 2014, and a sewer replacement in 2010. The property has had three routine housing inspections (2000, 2004, and 2006) which were all completed without any noted ongoing issues. The building's recent history is marked by two significant carbon monoxide (CO) detector incidents, though both were determined to be due to malfunction rather than actual CO presence, with no civilian injuries reported.

In 2009, there were two sewage backup incidents that required attention, and more recently, there have been occasional reports of street cleaning issues near the property in 2021 and 2024. The property was approved for a Cottage Food Operation in 2014, indicating some level of permitted commercial activity within the residential unit. While there have been routine maintenance issues and some street-level concerns, there are no documented safety violations or serious incidents directly affecting residents, and the building's permit history demonstrates regular upkeep and modernization efforts by the ownership.
