51 Moss St, San Francisco, CA 94103

The three-unit multi-family residential building at 51 Moss Street, owned by Seana Lyn & Otilio Quintero, underwent significant renovations in 2017, with comprehensive updates to all three units including bedroom relocations, kitchen and bathroom remodels, and the addition of new bathrooms and central heating systems. The 1906 structure received substantial electrical upgrades during this period, with new lighting, switches, and receptacles installed throughout.

Earlier maintenance records from 2003-2004 indicate the building addressed several fire safety issues, including central alarm system certification, garbage receptacle sprinkler requirements, and egress concerns, with all violations formally abated by February 2004. The building's history shows consistent maintenance and upgrading, with earlier work in the 1990s focusing on concrete repairs, termite remediation, and roofing. A 2011 complaint regarding unauthorized drywall installation on the second floor was promptly resolved within one day.

The property has maintained active compliance with major safety systems, evidenced by the replacement of the fire controller in 2006, though there was a brief period in 2013 noted for an overcrowded assembly issue that was corrected the same day. Recently, there have been multiple 311 calls regarding exterior maintenance issues, primarily related to garbage and debris, with the most recent being in January 2025. Two illegal parking complaints from mid-2024 were resolved with citations, and there is an open noise complaint from July 2024 that remains unresolved.
