515-517 3rd Ave, San Francisco, CA 94118

The two-unit residential building at 515-517 3rd Avenue in San Francisco's Inner Richmond neighborhood is a century-old, two-story flats and duplex structure currently owned by He Jian. The building has undergone significant renovations in recent years, with the most substantial work occurring in 2022, including a comprehensive remodel of Unit 515 featuring the addition of two bathrooms, kitchen relocation, bedroom modifications, and installation of a new laundry room, along with the construction of a rear deck (10'x14') and associated electrical and plumbing upgrades, all completed at a cost of approximately $85,000.

The property previously underwent significant improvements in 2008, including window replacements, staircase repairs, and second-floor bathroom and kitchen remodeling, though a proposed three-story rear addition from 2007 was cancelled. The building's history includes one notable complaint from 2012 regarding overcrowding and unauthorized rental activities, though this was promptly abated within six days. Earlier complaints from 2008 concerned unposted construction permits and noise, which were also resolved.

Infrastructure issues outside the building have been documented through 311 calls, including two instances of blocked driveways in 2023, a sewage vent issue in 2020, and various street maintenance and parking concerns, though these are generally routine urban issues not specific to the building's condition. While there were some sidewalk defects reported in 2017 and utility excavation concerns in 2012, these were addressed by city services. The property's renovation history demonstrates regular maintenance and upgrading of facilities, with no recent building code violations or planning complaints on record.
