547-549 6th Ave, San Francisco, CA 94118

The two-unit residential building at 547-549 6th Avenue in San Francisco's Inner Richmond neighborhood is a two-story flats/duplex structure built in 1907, currently owned by Stephen Ken Wong. The property has experienced several significant maintenance and compliance issues in recent years, most notably a series of active violations filed in October 2022 related to unapproved wiring, stair repairs, and an unauthorized rear storage building, which were formally documented in an August 2024 Notice of Violation.

The owner has taken some steps to address these violations, as evidenced by completed permits from November 2024 for stair repairs, removal of an existing shed, and rectification of unauthorized wiring. A more recent positive development includes the issuance of an electrical permit in March 2023 for a new metering system installation, showing some commitment to system upgrades. The building's maintenance history shows prior improvement work, such as kitchen counter replacement in 2011 and window replacements in 1997 (though the latter permit expired).

Recent 311 calls near the property have primarily concerned parking violations on the sidewalk, with multiple citations issued between 2021 and 2023, suggesting a recurring issue with parking enforcement in the area. Planning records indicate there was an effort to address unauthorized structures and repair dry rot damage to exterior stairs, though it appears some compliance issues remain, as the building still has active violations related to various building code requirements. The property has also generated several sanitation-related service calls, including requests for garbage can management and general cleaning in the vicinity, though these appear to be more related to street maintenance rather than direct building issues.
