419 34th Ave, San Francisco, CA 94121

The three-unit multi-family residential building at 419 34th Avenue in San Francisco's Outer Richmond neighborhood is a two-story flats and duplex structure owned by Frank Lee Yien and constructed in 1979.

The building's documented history shows minimal major renovations or incidents over the past several decades. The most significant recorded improvement was a complete reroofing project undertaken in September 2000, with an investment of $9,100, which has since been marked as complete.

This represents the only building permit on file for this property, suggesting either limited maintenance needs or potentially incomplete records of past work. The relatively sparse permit history could indicate that most building systems and elements remained in good condition since the last major work was performed over two decades ago, though this would warrant independent verification through visual inspection or additional records review.
