538-540 Guerrero St, San Francisco, CA 94110

The two-unit, two-story multi-family residential building at 538 Guerrero Street, owned by Johnny Wong & Anne Marie Lu, has undergone significant recent renovation activity, particularly in 2023. The most notable events include a major renovation that generated some community concerns in June 2023 regarding unpermitted work and health/safety issues, followed by a legitimate permitted kitchen and bathroom remodel in June 2023 (costing $83,033) which included several fixture replacements.

This renovation period was accompanied by electrical upgrades, including a complete rewiring of one unit with new subpanel installation and service upgrade to 200 amps (completed September 2023), as well as plumbing updates affecting bathroom, kitchen, and laundry areas (completed July 2023). A 200-amp meter main installation permit was issued in February 2024.

The building's maintenance history shows attention to essential systems over the years, including reroofing work completed in 2019 ($17,500) and earlier improvements such as mineral siding installation (1993), anchor bolt installation (1991), and kitchen remodeling (1985). Recent 311 calls indicate some ongoing neighborhood issues, though these appear unrelated to the building's condition, including recurring matters with illegal parking and street cleaning needs throughout 2020-2024, and one instance of tree maintenance required as of October 2024.
