540 Lake St, San Francisco, CA 94118

540 Lake Street is a 2-story, 4-unit multi-family residential building constructed in 1925, currently owned by the Ng 2002 Revocable Intervivo Trust. The property has undergone several significant improvements over the past few years, with the most recent major renovation completed in March 2023 involving the replacement of 16 street-facing windows with energy-efficient aluminum-clad wood double-hung windows. Between 2018 and 2019, the building underwent substantial unit improvements including a complete kitchen remodel, bathroom upgrades, electrical panel relocation, service upgrades to 200 amps, and plumbing modifications in Unit 1.

The building has a history of addressing maintenance issues, with records showing three separate sewer backup incidents in late 2018 that were promptly resolved, and a window replacement project to improve energy efficiency completed in 2023. The property experienced two significant routine housing inspections in 2001 and 2008, which identified various fire safety and security concerns including blocked exits, combustible storage, and inadequate self-closing doors. All violations were abated by June 2002, and during the 2008 inspection, issues such as garbage receptacle placement and security device requirements were addressed.

A recent fire complaint from September 2024 regarding blocked exits was resolved by October 2024. The building's maintenance history shows regular upkeep, including reroofing projects in 1989 and 2019, and various unit-specific improvements. Parking-related issues have been documented through multiple 311 calls between 2018 and 2023, primarily involving blocked driveways, while a noise complaint regarding garbage collection was recorded in mid-2020. The property's recent improvements and prompt response to violations and maintenance issues suggest active management, though the building has had recurring concerns with parking and occasional maintenance challenges such as the 2018 sewer issues.
