690 7th Ave, San Francisco, CA 94118

The two-unit residential building at 690 7th Avenue in San Francisco's Inner Richmond district is a two-story flats and duplex structure built in 1948, currently owned by Bony C. Tsang and Jennie Hsing.

The building has undergone several permitted modifications over the years, including a significant ground floor conversion in 1993 that added a bedroom, playroom, and toilet facilities, as well as window upgrades in 1986 when aluminum windows were installed. Earlier that same year, repairs were made to address damage at the side stairs.

A concerning incident occurred in April 2012 when unpermitted interior work was reported in the garage involving framing and construction, though this complaint was resolved within two days and is currently listed as Not Active. The only other recorded service issue was a minor street maintenance matter in July 2014 involving a burnt-out street light on a wooden pole, which was promptly repaired by PG&E within two days of being reported. While the building's documented history shows primarily routine maintenance and improvements, the 2012 unpermitted construction incident highlights the importance of proper permitting procedures, though it's worth noting that this activity was quickly addressed through the complaint process.
