1379-1381 21st Ave, San Francisco, CA 94122

The Wong 1991 Trust-owned property at 1379-1381 21st Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Central Sunset neighborhood. Constructed in 1940 in the flats and duplex style, this building has undergone several significant maintenance and improvement projects over the years.

Most notably, in September 2017, the building received a major roofing upgrade with a completed $11,000 re-roofing project. Earlier improvements include the installation of aluminum windows in February 1988, which was successfully completed. The building's history includes one documented water-related complaint from March 1995, which involved water issues affecting both a garage and a tenant's bathroom.

This complaint was resolved within approximately two weeks (by March 29, 1995) and involved concerns about water backflow affecting both the tenant's tub and the garage area. The complaint resolution indicated a temporary situation related to the tenant's use of the bathtub for pregnancy-related comfort, though the owner initially attributed some of the issue to tenant actions. Since that incident, there have been no recorded complaints or reported water issues, and the property has maintained an active status without any open violations or current complaints on file.
