607-609 4th Ave, San Francisco, CA 94118

The property at 607-609 4th Avenue in the Inner Richmond is a two-story, two-unit multi-family residential building constructed in 1906, currently owned by Amanda R & Jason A Yan since 2020. The building's maintenance record shows several significant improvements, with the most recent major work being a $22,000 reroofing project completed in 2021.

A critical compliance issue occurred in 2013 when violations were filed regarding unauthorized conversion of the garage/basement area into habitable space, including a bathroom and kitchen, which were subsequently addressed through proper demolition and electrical/plumbing work totaling approximately $3,000 to restore the space to code compliance by December 2013. Historical records show prior improvements including a comprehensive remodel of four bathrooms and two kitchens in 2002 ($10,000), and some dry rot repairs to the garage area in the same year. More recent history of the property shows ongoing parking-related issues, with multiple citations issued for driveway blocking between 2021 and 2024, including five citations in 2024 alone.

Two instances of sidewalk parking were reported in late 2021. While there have been recent complaints about garbage and debris (though nothing was found at the location during inspections), these are largely routine municipal issues not directly related to building conditions. The building's administrative review in 2015 confirmed its proper classification as a two-story over basement duplex property, documenting its legal use and occupancy status based on various municipal records.
