446 Diamond St, San Francisco, CA 94114

The property at 446 Diamond Street is a 3-story, 2-unit multi-family residential building constructed in 1908, currently owned by Debra Reabock. The building has undergone significant renovations and modifications over the past two decades, with the most substantial recent work involving the conversion of ground floor living and bedroom areas into a 535 sq ft accessory dwelling unit (ADU) completed in 2021-2022, which included new kitchen facilities, electrical updates, and plumbing work.

This ADU installation followed a 2021 violation notice regarding an unauthorized wet bar installation, which was ultimately resolved by December 2022. Other notable improvements include a new sewer lateral installation completed in October 2023, a ground floor bathroom addition in 2016, and various garage modifications including widening the garage door in 2017.

Historical records show the building underwent a significant transformation in 2013-2014, including ground floor room development, kitchen remodeling, and seismic upgrades. The property has had some maintenance issues in the past, including a 1998 incident involving water drainage into a neighboring basement, though this was promptly addressed. Recent 311 calls primarily relate to parking issues and street maintenance matters rather than building-specific concerns.
