63 John St, San Francisco, CA 94133

The two-unit residential building at 63 John St in Nob Hill, classified as a Flats & Duplex structure, was built in 1910 and is currently owned by Gina Dinh Chang. The building underwent significant rehabilitation in 2006, with comprehensive work including foundation replacement due to dry rot on multiple sides (with costs totaling $65,000), conversion of the layout to add and relocate various living spaces, and complete electrical system upgrades including installation of 40 lights, 30 switches, 55 receptacles, and 22 circuits to support the remodeled interior.

These improvements, costing over $114,000 in total, transformed the property into a more modern configuration featuring four bedrooms, two kitchens, two bathrooms, two living rooms, and two family rooms. Earlier improvements to the property included aluminum window installation in 1986 and reroofing in 1995. The building's maintenance and incident history shows regular municipal engagement primarily focused on street and sidewalk cleanliness, with recent cleaning requests in 2023.

There have been several instances of waste management concerns in the vicinity between 2013 and 2020, including reports of garbage and toters being left out, though these were typically resolved through municipal intervention. The only recorded fire-related incident was a smoke scare, though no injuries were reported. The property's documented history suggests it has received significant modernization and maintenance attention, particularly during the substantial 2006 renovation period, with no major safety or structural issues reported since those comprehensive foundation repairs.
