638-640 5th Ave, San Francisco, CA 94118

The property at 638-640 5th Avenue is a three-story, two-unit multi-family residential building located in San Francisco's Inner Richmond neighborhood. Built in 1907 and currently owned by the Henry & Amy Yu Revocable Trust, this apartment building has undergone several significant renovations and faced notable compliance issues over its history. Most recently, in 2022, both units received substantial window upgrades with two separate permits totaling over $54,000, replacing a combination of street-visible and non-visible windows with energy-efficient alternatives.

The building underwent a major remodeling project in 2000-2001, which included creating new living spaces and a deck, though this work triggered violations due to unauthorized construction of steel beams, truss joists, and foundation work exceeding permit scope, requiring subsequent corrections that were finally abated in 2011. The property has maintained active compliance with housing and safety regulations since those earlier violations were resolved. A tenant buyout occurred in November 2021, with one tenant receiving $31,000.

Recent records show recurring issues with parking violations near the property, with multiple citations for blocked driveways between 2021 and 2024, though these are typically external issues not directly related to building conditions or management. The most recent building permits and improvements suggest proactive maintenance of major systems, particularly with the recent window upgrades improving energy efficiency and aesthetics. The property has undergone regular routine inspections, and all known violations have been addressed through proper channels, indicating current compliance with San Francisco housing standards.
