1671-1675 Clay St, San Francisco, CA 94109

The 13-unit, three-story apartment building at 1671-1675 Clay Street in Nob Hill, constructed in 1922, has undergone significant improvements and renovations in recent years, with particular emphasis on unit upgrades and safety systems. Between 2019 and 2022, multiple residential unit renovations were completed, including kitchen and bathroom remodels, with work performed in Units 1, 4, 5, 6, 8, 12, and others, typically involving kitchen relocations, bathroom rehabilitations, and washer/dryer installations. Building-wide improvements included a comprehensive fire alarm system upgrade in 2021 to meet SF Fire Code requirements (SFFC 1103.7.6.1), installation of low-frequency sounders in sleeping areas, and subsequent updates to the fire alarm system components in 2022.

The building has achieved compliance with San Francisco's soft-story retrofit requirements as a Tier 3 building, with work completed and a CFC issued. The property has a history of fire safety concerns, with multiple fire code violations recorded in 2017 and 2020, including issues with alarm systems, extinguishers, blocked exits, and minimum egress lighting, though these violations were eventually abated or corrected. In March 2020, there were complaints about non-permitted construction work during the COVID-19 shelter-in-place period, and in January 2020, there were concerns about heavy construction work occurring on Saturday mornings.

The building's maintenance history shows attention to basic infrastructure, with a sewer pipe replacement in 2009 and various plumbing and electrical upgrades. Historical violations from 2011-2014 included issues with security, lighting, and appliances, which were addressed during that period. The most recent fire-related incidents registered were false alarms or detector malfunctions, with no civilian injuries reported.
