1637 Clay St, San Francisco, CA 94109

The 12-unit multi-family residential building at 1637 Clay Street in Nob Hill, owned by Hjc Enterprises Llc, has undergone significant changes and faced several challenges since its 1911 construction. Most notably, the building experienced substantial water damage in early 2024, affecting units B, 3, 7, and 11, which required $16,500 in repairs to replace water-damaged sheetrock. This incident raised concerns about worker safety and lead paint compliance during subsequent reconstruction, as reported in tenant complaints.

The building's recent history shows substantial improvements to safety systems, including the installation of a comprehensive fire sprinkler system for ground floor ADU units in 2019 ($18,000), at a cost of $14,000, and a new fire alarm monitoring unit in 2020. The property underwent significant structural modifications between 2018-2022, including the addition of ADUs (Accessory Dwelling Units) at the ground floor, with associated structural improvements and electrical work. The building was designated as a Tier 3 soft-story structure, and records indicate that required seismic retrofitting work has been completed. The property's inspection history reveals various issues addressed promptly, including multiple fire safety violations in 2001 related to smoke enclosure doors and combustible storage, and more recent fire safety concerns in 2020 regarding combustible materials and weeds.

The building has maintained active compliance with safety regulations, with most violations being resolved promptly. Recent maintenance records show attention to basic upkeep, though there have been periodic reports of graffiti and debris requiring attention. The property's utility systems have seen significant upgrades, including recent electrical improvements in 2020-2021 with new meters and electrical infrastructure. Historical records indicate past plumbing modifications, including solar water heating system work in 2013, though the primary focus has been on fire safety system improvements and structural modifications in recent years.
