58 Liberty St, San Francisco, CA 94110

The 7-unit, 2-story multi-family residential building at 58 Liberty St, owned by Parr John H & Philip C, has undergone several significant modifications and maintenance work since its construction in 1900. Most notably, the building completed a mandatory soft-story retrofit in 2019 (at a cost of $100,000), with temporary shoring work performed in late 2019, bringing it into compliance with San Francisco's seismic safety requirements.

More recent infrastructure maintenance includes a water service repair in October 2022 and a PG&E conversion from overhead to underground service completed in 2003. The property has experienced recurring sewer issues, with six sewage backup incidents reported between November 2024 and February 2024, all of which were resolved through field work by PUC Sewer Operations. The most recent building permit activity includes an administrative correction in July 2020 to confirm the dwelling unit count as 7 units.

The building's inspection history shows routine apartment inspections conducted in 2000 and 2006, with no significant violations or penalties recorded in these instances. Current infrastructure concerns include ongoing management of tree roots lifting the sidewalk, as recorded in a January 2025 urban forestry complaint. While the building is now compliant with seismic safety requirements, the recent pattern of sewer-related incidents suggests ongoing plumbing system challenges that have required repeated attention over the past year.
