62-64 Moss St, San Francisco, CA 94103

The three-story multi-family residential building at 62-64 Moss Street, constructed in 1911, is a four-unit structure owned by Leffers Tr and has undergone several significant improvements over the past decade. Most notably, between 2017-2018, a legal basement unit was created (including seismic upgrades, new columns, and footings), and comprehensive fire safety improvements were implemented, including the installation of a fire sprinkler system in the basement, a sprinkler monitoring system, and related electrical work. The building has also received substantial plumbing upgrades, with the installation of on-demand hot water heaters for units 62, 64, and 64A, and various electrical improvements including new circuits and a 100-amp subpanel installation.

The property has a history of addressing safety and compliance issues, with several building violations from 2003-2010 that have since been resolved, including concerns about ventilation, egress pathways, electrical outlets, and fire safety. Recent fire safety complaints from 2010, 2014, and 2021 regarding alarm systems and blocked exits were all promptly corrected. The building experienced one instance of water heater flue issues in 2011 that required correction, and underwent routine safety inspections in 2009 and 2010.

More recently, there have been multiple 311 calls between late 2024 and early 2025 regarding street cleaning and debris issues outside the building, though these are not directly related to the building's internal conditions. The property underwent significant upgrades in 2017-2018, totaling over $160,000 in improvements, including seismic upgrades and comprehensive life safety systems. These improvements were part of a broader effort to modernize the building and bring it into compliance with current safety standards, including the installation of escape windows and various mechanical, electrical, and plumbing upgrades. The building's most recent major works involved the addition of a legal basement unit and complete modernization of fire safety systems, suggesting a proactive approach to maintaining and upgrading the property over time.
