4162-4164 26th St, San Francisco, CA 94131

The property at 4162-4164 26th Street in Noe Valley is a four-story, three-unit multi-family residential building constructed in 1900, currently owned by Tony Szeto and Annie T F Kong. The building underwent significant safety and infrastructure upgrades between 2016-2018, including the installation of a comprehensive fire sprinkler system throughout the building with 62 sprinklers, electrical system upgrades with 200-amp service and four meters, and the installation of new furnaces for all units. However, there are several notable concerns in the building's history.

Most significantly, there are active violations from 2012 related to unauthorized excavation work in the crawl space and issues with a rear porch structure, which were referred to Code Enforcement Division. There were also multiple complaints in 2017 regarding unauthorized removal of property boundaries and fencing, and a 2013 complaint about potentially unsafe excavation work. The building's basement conversion and additional construction work has been the subject of various permits and planning records, including attempts to legalize basement unit conversion.

Recent maintenance and safety checks have shown improvements, with the 2022-2023 period showing primarily routine parking enforcement matters, though there was a fire complaint in 2022 regarding weeds and grass that was corrected by March 2023. Street space permits were issued multiple times between 2016-2018, suggesting some exterior work or temporary usage changes. The building's systems were significantly modernized during the 2016-2018 period, with improvements to plumbing, electrical, and fire safety systems, though some permits from this period are noted as expired. The property's recent history (post-2018) has been relatively stable, with no major new compliance issues reported, though there remains some uncertainty regarding the final status of the 2012 excavation violations, as they appear as active cases in the records.
