517 Lyon St, San Francisco, CA 94117

The two-unit residential building at 517 Lyon Street in the Park North neighborhood, currently owned by Hzhu Investment LLC, has a documented history of maintenance and safety compliance issues that were primarily addressed in early 2019. The property, constructed in 1900 and classified as Flats & Duplex, underwent an administrative review in April 2019 to confirm its occupancy as a legally recognized two-story, two-unit structure, which was successfully completed.

The building experienced significant habitability issues in late 2018, with multiple violations recorded between November 2018 and December 2018. These violations included heating system failures (with complaints about inadequate heat in living rooms and bedrooms), mold presence, malfunctioning appliances, window repairs needed, and the absence of required carbon monoxide alarms.

All these violations were addressed by March 2019, as documented by the completion of associated electrical permits and building permits. More recently, the address has had multiple 311 calls regarding encampments and parking enforcement issues in 2022-2024, although these are external to the building's condition and management. The property has been free of active building violations since early 2019, with no tenant buyouts recorded at this address.
