806 Arguello Blvd, San Francisco, CA 94118

The two-unit residential building at 806 Arguello Blvd, located in the Lone Mountain neighborhood, is a two-story flats and duplex structure built in 1904 and currently owned by the Elizabeth Mun Yip Trust. The property has undergone several significant improvements over the past decades, including a reroofing project completed in 2013 ($3,500) and a window replacement project in 2012 ($9,000) that involved installing 18 new vinyl windows not facing the street, along with repairing six steps at the lightwell.

In 1996, modifications were made to legalize two habitable rooms and a toilet on the ground floor. The building's history includes several concerning issues that potentially impacted resident safety and comfort, particularly in the late 1990s. A 1997 housing inspection revealed problems with the electrical system (blowing fuses), inadequate heating, and bathroom floor deterioration, while a 1995 complaint about an illegal basement unit was filed.

A plumbing complaint regarding a rusty gas pipe was reported in 2007, though it was quickly abated within one day. More recently, there has been one fire incident on record where an alarm system malfunctioned, with no civilian injuries reported. The property has experienced occasional issues in the surrounding area, including multiple instances of sidewalk parking violations (with at least three citations issued), graffiti incidents, and a loose garbage complaint in early 2024, though most of these external issues have been promptly resolved by the relevant authorities.
