163-165 Blake St, San Francisco, CA 94118

The two-unit residential building at 163-165 Blake Street in the Lone Mountain neighborhood is a two-story flats and duplex structure built in 1924, currently owned by David Man Hok Leong and Chu M. The building's documented history shows relatively few major structural modifications, with significant work performed in the early 1990s including the legalization of a second unit and third floor (completed in 1992) and reroofing work (completed in 1990).

A notable building complaint was filed in 2008 regarding unauthorized construction of a kitchen and bedroom in the basement, though this issue was marked as not active following its abatement in September 2009. The property has experienced recurring street-level maintenance issues in recent years, though these are primarily external to the building itself. The most recent complaints include general cleaning concerns (with reports of loose garbage) in June 2024, and there have been multiple similar incidents in 2022-2024.

Other external issues documented include instances of human or animal waste (July 2021 and August 2023), graffiti (August 2022), and some parking-related concerns (April 2020). Two service requests related to overflow and abandoned waste were successfully resolved by Recology in early 2022. While these street-level maintenance matters are documented through 311 calls and other city services, they primarily reflect conditions in the surrounding neighborhood rather than specific issues with the building itself.
