474-478 Sanchez St, San Francisco, CA 94114

The three-unit residential building at 474-478 Sanchez Street, owned by Andrew Tam, is a three-story flats and duplex structure built in 1912 in the Eureka Valley/Dolores Heights neighborhood. The property has undergone several significant improvements in recent years, with the most substantial ongoing work occurring in Unit A, which includes a kitchen and bathroom remodel, electrical upgrades, and plumbing improvements for new appliances in mid-2024. Recent maintenance includes a complete roof replacement in 2008 and a tankless water heater replacement completed in 2024.

A notable water intrusion issue was reported in March 2023, involving leaking fixtures and ceiling damage, though this was subsequently addressed by July 2023. The building has experienced various violations and complaints over the years, with the most recent cluster of issues identified in March 2023, including problems with weatherproofing, lighting, and interior surfaces, as well as concerns about potential lead-based paint. These violations were marked as not active, suggesting they were resolved or addressed. Earlier violations from 2011 regarding a wooden utility ladder were also resolved.

The property has maintained regular updates to essential systems, including plumbing (with a sewer line replacement completed in 2012) and electrical systems (with recent rewiring work completed in 2022). Recent 311 calls primarily relate to exterior maintenance issues, including graffiti and garbage concerns on the property grounds, with one sidewalk defect case still open as of March 2022. The property's maintenance history shows a mix of reactive and proactive care, with significant investments in upgrading living conditions and addressing health and safety concerns. Regular inspections and permits indicate ongoing attention to compliance with building codes and maintenance requirements, though the 2023 violations suggest some temporary deficiencies in building upkeep standards.
