591-593 Naples St, San Francisco, CA 94112

The two-unit residential building at 591-593 Naples Street in the Excelsior neighborhood, owned by Kevin Liu and Judy Weng, has a complex history since its construction in 1927. The property experienced significant moisture issues, with multiple mold and dry rot remediation projects undertaken in 2008 ($60,000), followed by a commercial-to-residential conversion work completed in 2010 ($65,000) that included ground-floor remodeling.

Between 2007-2011, various infrastructure improvements were completed, including window replacements, plumbing system upgrades, and electrical system enhancements (new 100-amp panel, lighting, and receptacles). The building has faced several code compliance issues and resident complaints over the years, with the most pressing current concerns being an active complaint from June 2024 regarding unauthorized modifications to the rear exterior (including new stairs, shed, windows, and skylights) and potential fire safety violations. Historical complaints have documented various maintenance and safety issues, including heating system failures in 2007, window problems, and mold issues in 2008.

An incident in 2016 involving uncontained paint chips and lead paint concerns was resolved shortly thereafter. The property has undergone multiple permit-required improvements, including bathroom renovations, heating system repairs, and electrical upgrades, though some work has been performed without proper permits according to recent complaints. The building's history also shows regular parking enforcement activity in the vicinity, with multiple citations issued for driveway blocking between 2019-2024.
