101-105 18th Ave, San Francisco, CA 94121

The 9-unit, 3-story multi-family residential building at 101-105 18th Avenue in the Lake-The Presidio neighborhood, owned by George K & Nancy N Chen Family, has undergone several significant upgrades and faced some notable challenges since its construction in 1915. Most importantly, the building completed a mandatory soft-story retrofit in 2016 at a cost of $50,000, bringing it into compliance with seismic safety requirements as a Tier 3 building. In 2019, the building received two fire code violations related to its alarm system and owner contact posting requirements, both of which were subsequently abated.

The building experienced a serious incident in December 2015 when a brick chimney from the neighboring building (1711 Lake Street) collapsed onto this property, damaging an exterior wall and window; repairs completed in 2015 included this incident's remediation as well as sewer line replacement and plumbing updates. Historical maintenance and improvement work includes window replacements on the 18th Avenue and south sides in 1999, stucco renovation in 1998, and reroofing in 1996, though the latter two permits are listed as expired. The building faced multiple fire safety violations in 2002, which were all abated by December 2002, including issues with egress obstruction, smoke enclosure doors, fire escape maintenance, and combustible storage.

More recent inspections in 2008, 2017, and 2019 have been resolved without any noted ongoing concerns. The property has generated several recent municipal service calls in 2024, primarily related to parking issues and street maintenance, while three fire complaints related to street numbering and alarm systems were recorded between 2017-2019, though two were found to have no merit and the third was addressed. The building's most recent fire incident records show three responses between 2017-2019, none of which resulted in civilian injuries.
