23-25 Moss St, San Francisco, CA 94103

The Leffers Trust-owned property at 23-25 Moss Street is a 2-story, 3-unit multi-family residential building constructed in 1909 in San Francisco's South of Market neighborhood. The building has undergone significant renovations and safety improvements between 2014-2016, including substantial structural work, mechanical updates, and modernizations totaling over $100,000.

Major improvements in 2014-2015 included voluntary structural strengthening of the lower unit, comprehensive rewiring with a new 200-amp service, plumbing upgrades including the installation of a new radiant heating system, and kitchen remodels across multiple units. The property had several code violations in 2003 and 2010 related to fire safety and building maintenance, including issues with stairs, handrails, and combustible storage, though all violations were resolved by 2013. More recently, there were two complaints in 2020 regarding unauthorized business activities in the building's courtyard and common areas, though these complaints are now marked as not active.

The building's fire alarm system experienced a malfunction in February 2015, which was promptly corrected. Recent service requests in 2023-2024 primarily involve parking issues and street cleaning matters outside the building, with multiple reports of illegal parking and encampments in the vicinity of the property. The building's most recent major renovation work was completed in 2016 when final inspections were conducted for various approved permits, including structural, plumbing, electrical, and mechanical work.
