53-57 Pearl St, San Francisco, CA 94103

The 6-unit apartment building at 53-57 Pearl Street in Mission Dolores, owned by Ronald Bonshaw Koo, is a three-story multi-family residential structure built in 1907. The property has undergone several significant improvements over the past decade, with the most recent being kitchen remodels in units 55a and 57a completed in 2021-2022, which included electrical and plumbing upgrades. In 2015, the building completed a mandatory soft-story retrofit to comply with seismic safety requirements, along with garage and basement electrical improvements.

Other maintenance work has included reroofing in 2016 and gas line upgrades in 2017 serving units 53a, 55a, and 57a. The building's maintenance record shows attention to safety concerns, particularly in 2004 when multiple violations were addressed, including emergency egress issues, security viewer requirements, and smoke detector installation - all of which were abated within weeks. A 2011 complaint about improper construction dust containment was also resolved promptly.

The property has completed all necessary safety inspections, received a Tier 4 soft-story compliance certificate, and experienced one tenant buyout in 2016 involving two tenants for $15,000. Recent 311 calls have primarily concerned street-related issues rather than building-specific problems, with the most recent case from August 2024 regarding abandoned furniture. The building's maintenance and improvement history suggests regular upkeep and responsiveness to regulatory requirements, with no active violations or unresolved building-specific complaints on record.
