779 Treat Ave, San Francisco, CA 94110

The three-unit, two-story multi-family residential building at 779 Treat Avenue in the Inner Mission, owned by the Yee Lung Hong Irrevoc Tr and constructed in 1980, has undergone several significant modifications and faced regulatory scrutiny over its lifetime. The property has maintained regular upkeep, with documented improvements including reroofing projects in 2008 (cost: $8,500) and 1989, installation of a fire sprinkler system in 2007, and various bathroom and utility facility upgrades between 1983 and 1993.

A noteworthy incident occurred in August 2007 when multiple violations were documented regarding unauthorized construction of additional bathroom facilities and a bedroom in the basement, which prompted the city to issue numerous citations related to building permits, plumbing requirements, fire safety, and ventilation issues; however, these violations were resolved by December 2007. Earlier modifications to the building's infrastructure include the legalization of a ground floor storage room in 1992 (though this permit expired), and the installation of a skylight in 1989.

More recently, in July 2018, there were two 311 calls regarding encampment reports near the property, though one was determined to be invalid while the other was resolved through Public Works intervention. The building's overall maintenance history shows regular updates to essential systems, including fire safety equipment, though prospective tenants should note the property's history of unauthorized modifications requiring subsequent code enforcement intervention.
