1430 21st Ave, San Francisco, CA 94122

The two-unit multi-family residential building at 1430 21st Avenue in San Francisco's Central Sunset neighborhood is a 2-story flats and duplex structure built in 1939, currently owned by the Wong/Mak Family Trust. The building's documented history shows two significant permit applications: one from July 1985 that successfully completed the installation of a laundry room and half bathroom in the basement, and an earlier application from July 1982 that was cancelled prior to completion.

More recently, in March 2017, there was a request for a temporary moving sign in a 20-foot zone, though this request was ultimately closed as a duplicate of another application and was not issued. The building's documented history shows relatively few incidents or issues, with the most substantial modification being the 1985 basement improvements that added laundry facilities and an additional bathroom.

The cancelled permit from 1982 and the temporary sign request from 2017, which was not related to building conditions or resident concerns, suggest normal administrative processes rather than any significant building-related matters. The property's record appears to be relatively quiet over the past several decades, with no documented safety violations, emergency calls, or other notable incidents that would impact resident experience.
