473-475 Parker Ave, San Francisco, CA 94118

The 473-475 Parker Avenue property is a three-story, two-unit multi-family residential building located in the Lone Mountain neighborhood, owned by Mark Nassi and Victoria Deitc and constructed in 1940. The building underwent significant modifications in 2005, including a substantial $380,000 interior remodel that involved demolition of interior walls and doors, and the controversial removal of an unwarranted ground-floor unit with kitchen and bath facilities, which was converted to storage.

During this renovation period, there were also attempts to add new decks on the first and second floors, though these permits were ultimately cancelled. The electrical system received considerable attention in 2005-2006, with successful installations including a new 12/24 house panel system, a three-stop residential dumbwaiter, and correction of code violations, though several electrical permits from this period were cancelled, including attempts to rewire the building and install additional lights, switches, and circuits.

The property has experienced minimal maintenance issues in recent years, with only two recorded 311 calls: a 2021 hazardous materials incident involving liquids on the street or sidewalk, and a 2019 report of non-offensive graffiti on a pole, both of which were resolved. Planning records indicate a proposal to combine the second and third floors into one unit while creating a second unit on the ground level, though it's unclear if this work was ever completed, as there is no recent record of such modifications. The building's permit history shows a concentrated period of renovations in 2005, followed by completed electrical upgrades in 2006, but no documented major works in recent years.
