316 4th Ave, San Francisco, CA 94118

This two-unit residential building located at 316 4th Avenue in San Francisco's Inner Richmond district is a two-story flats and duplex structure built in 1900, currently owned by Sebastian Colabianchi. The building's maintenance history includes a reroofing project from 2003 with a cost of $5,800, though this permit has since expired.

A significant safety concern was documented in 1995 when housing inspection services investigated illegal wiring for heating and a non-functional gas furnace, though this issue was marked as not active by March 1996. More recently, in September 2012, there was a fire safety complaint about blocked exits, but this condition was corrected the same day. The property has been the subject of multiple 311 calls over recent years, with the most recent incidents occurring in May 2024 involving shared spaces violations and a child-related request that was transferred to the Department of Public Health's Environmental Health division.

Between 2019 and 2022, there were several parking-related complaints, including blocked driveways and parking on sidewalks, most of which were resolved when responding officers were unable to locate the offending vehicles. The address has also experienced recurring issues with waste on public streets and sidewalks, with three documented incidents between 2019 and 2020, all of which were resolved. While none of these issues are directly related to the building's internal systems or structure, they may impact the overall environment around the property.
