246-248 Parker Ave, San Francisco, CA 94118

The two-unit residential building at 246-248 Parker Avenue in the Lone Mountain neighborhood is a 2-story flats/duplex structure built in 1900, currently owned by Shapiro Properties LLC. The property has undergone significant improvements in recent years, most notably a series of safety upgrades in 2023, including the installation of new sprinklers, electrical rewiring of ground floor kitchen outlets and lighting, and various plumbing modifications.

In 2019, the building underwent substantial work to legalize a ground floor studio unit at the rear, which included comprehensive fire sprinkler installations throughout the first floor and modifications to meet fire safety requirements. Earlier major renovations included reroofing in 2012 and critical foundation and girder repairs in 2011, demonstrating ongoing maintenance of the building's structural integrity. The building's history includes some problematic periods, particularly in 2004 when multiple housing code violations were recorded, including issues with heat, hot water, and plumbing systems in unit 246, though these were all resolved by June 2004.

A more recent concern arose in 2018 regarding a potentially un-permitted dwelling unit and short-term rentals, which was addressed through subsequent legalization efforts. The property has experienced various maintenance and operational challenges over the years, including issues with windows, plumbing, and heating systems, as well as more recent concerns regarding parking violations and street-related issues as indicated by multiple 311 calls and citations between 2023 and 2024. However, the recent pattern of permits and completed work suggests a concerted effort by the current ownership to bring the building up to current codes and improve resident safety systems.
