1558-1560 Clay St, San Francisco, CA 94109

This two-unit residential building, located at 1558-1560 Clay Street in the Nob Hill neighborhood, is a 2-story flats/duplex structure built in 1908 and currently owned by the Bow & Jennie Wong Family Trust. The property has undergone significant renovations in recent years, most notably in 2023, when approximately 1,000+ square feet of habitable space was created in the existing ground floor utility areas, including a kitchenette, wine room, gym, media room, and bathroom, with associated plumbing and electrical work costing $180,000. This project required multiple permits and revisions, including a recent November 2024 revision to document the removal of a non-load bearing wall between the media room and hallway.

The building's maintenance history shows attention to safety features, including the replacement of rear egress stairs in 2019 (costing $20,000) and the removal of a problematic utility ladder in 2010 following a violation notice. Historical plumbing issues were documented in 2003 regarding sewage leaks between buildings, but these were promptly addressed within days of being reported. The property underwent various improvements in the early 1990s, including kitchen and bathroom remodels.

Recent infrastructure upgrades include a heat pump installation (2023) and the addition of a new subpanel with 200-amp service. A tenant buyout occurred in May 2022 for $25,000, involving one tenant at 1560 Clay Street. The building's recent maintenance and improvement history suggests active property management, with most recent permits showing completed work rather than outstanding maintenance issues.
