427-431 Greenwich St, San Francisco, CA 94133

The 427-431 Greenwich Street property is a 2-story, 5-unit multi-family residential building located in Telegraph Hill, built in 1907 and currently owned by the Gee Family Trust A. The building has undergone several significant maintenance and improvement projects over the past two decades, with the most recent work occurring in 2015 when roof deck repairs were completed due to wood decay, and in 2014 when four side windows were replaced with vinyl single-hung windows. A more comprehensive window replacement project was carried out in 2007, involving the installation of 11 new vinyl windows in various non-street-facing rooms.

Historical records indicate routine housing inspections took place in 1999, 2003, and 2006, with some complaints regarding paint deterioration on the east wall and concerns about a potential unpermitted deck in 1998-2000, though these issues appear to have been resolved. More recent building incidents include two carbon monoxide detector activations (one malfunction and one with no CO detected). The property has experienced some infrastructure challenges, as evidenced by two sewage-related incidents in 2021 and 2024, though these were not directly linked to the building's systems according to 311 reports.

There have been multiple requests related to scooter service and sidewalk access in the vicinity of the property between 2020 and 2024, suggesting ongoing urban mobility challenges in the area. The building's maintenance record shows regular attention to critical systems, with particular attention paid to windows, roofing, and stairs over the years. While there have been various urban infrastructure issues documented through 311 calls, most recent complaints have been external to the building itself, focusing on street cleaning and mobility concerns rather than building-specific maintenance or safety issues.
