1347-1349 22nd Ave, San Francisco, CA 94122

The property at 1347-1349 22nd Avenue in the Central Sunset neighborhood is a multi-family residential building (class flats & duplex) owned by Walter Wan Fai & Wendy Wong. The building has undergone several significant modifications over the years, with the most substantial being a vertical addition completed in 2004 at a cost of $180,000, followed by horizontal additions in 1992.

The building has experienced multiple unauthorized construction issues, including complaints about an unpermitted rooftop room modification in 2017, a suspected illegal unit in the basement and garage in 2000, and unauthorized construction against the backyard fence in 2004. A notable incident occurred in December 2005 when construction work allegedly caused flooding in the adjoining property at 1351 22nd Avenue. The property has undergone several electrical and structural improvements, including the installation of a new floor, electrical fixtures, and equipment in 2005, though some permits were for relatively minor work such as garage door opener replacement and sidewalk modifications.

More recently, there has been a pattern of parking-related issues near the property, with multiple complaints about blocked driveways and parking violations recorded between October 2024 and December 2024, including at least two citations issued for blocked driveways. There was also a street lighting issue reported and resolved in October 2024. The building's history shows a mix of permitted modifications and regulatory compliance issues, particularly regarding unauthorized construction and its impact on neighboring properties, though many of the older complaints have since been resolved.
