651-657 Shotwell St, San Francisco, CA 94110

The property at 651-657 Shotwell Street is a two-story, four-unit multi-family residential building located in San Francisco's Inner Mission neighborhood. Built in 1900 and currently owned by Loo Bok Sing & Wanda Revoc, the building has undergone several significant improvements over the past decade. In 2016, the building received a comprehensive electrical service upgrade to 200 amps with five meters, and major improvements including furnace installation with heat ducts, reroofing, and repairs to doors and stairways were completed to address multiple housing code violations.

These violations, filed between February and September 2016, included issues with heat, lighting, water damage, interior surfaces, security requirements, and smoke/carbon monoxide detection systems, all of which were officially abated by April 2016. More recent concerns include recurring moisture issues, with complaints about leaks and mold filed in 2016, 2018, and 2019. The most recent building-related incident was a complaint about improper lead paint containment in October 2019.

The property has undergone multiple street space permit applications in 2018 and 2019, and there have been several infrastructure improvements, including plumbing work and electrical upgrades. Recent activity around the building (2024-2025) has primarily involved external concerns such as sidewalk cleaning needs and parking violations, though these are not directly related to the building's condition. The building's fire safety systems have had two recorded activations - one for smoke detection and another for CO detection, though neither involved actual fires or injuries.
