1921 Lake St, San Francisco, CA 94121

Located at 1921 Lake Street in The Presidio/Lake neighborhood, this two-story, four-unit multi-family residential building was constructed in 1917 and is currently owned by Kenneth J. and Jeanne W. Lomb.

The building has undergone several significant improvements and modifications over the past two decades, most notably the recent addition of an accessory dwelling unit (ADU) in 2020, completed in conjunction with seismic retrofits valued at $174,000. The property has received substantial infrastructure upgrades, including a complete electrical system overhaul in 2015 with new 200-amp service and five-meter panels, plumbing improvements such as sewer lateral replacement in 2018, and various unit renovations including bathroom and kitchen updates in multiple apartments between 2015-2019. Historical records indicate that the building experienced several maintenance and safety compliance issues in the mid-2000s, including multiple fire safety violations in 2005-2007 related to smoke detectors, fire extinguishers, and egress obstructions, though all were subsequently resolved.

There were also heating system problems, with complaints about no heat for extended periods in 2006-2011, and a boiler permit violation in 2016. Recent maintenance history suggests ongoing investment in building improvements, with no active violations or complaints on record since 2016. The property has generated periodic police and municipal service calls primarily related to street parking issues, with the most recent external incident recorded in 2024 regarding furniture debris on the property. The building's recent focus has been on unit upgrades and structural improvements, with no significant safety or habitability issues reported in the past several years.
