636-638 Russia Ave, San Francisco, CA 94112

The Wong Henry & Lam Shirley-owned duplex at 636-638 Russia Avenue in the Excelsior neighborhood is a two-story multi-family residential building constructed in 1947. The property underwent significant improvements in 2016, including comprehensive renovations on both floors. The first floor saw the creation of new partition walls to enclose existing workshop/storage spaces, installation of a new half bathroom, relocation of water heaters and furnaces, structural upgrades to the exterior wall including plywood and anchor bolt installation, and an electrical panel upgrade at a cost of $23,000.

The second floor renovation, costing $4,000, involved bathroom remodeling including a new vanity, as well as upgrades to lighting and outlets in unit 636. The 2016 improvements were accompanied by the appropriate plumbing (installation of new bathrooms and water heaters) and electrical permits (including lighting, outlet replacements, and service panel upgrade), all of which have been marked as complete. An earlier electrical modification from 2004 was also recorded for a garage door operator installation.

The building's maintenance history includes several 311 calls, with the most recent in October 2021 reporting hazardous materials (specifically, oil/paint/liquids) that were resolved by DPW, and earlier incidents in 2016 and 2015 relating to general street cleaning and an abandoned vehicle, respectively. A notable planning record indicates an attempt to create new rooms in an existing open garage space, though documentation specifies limitations on bathroom and wet bar installations, though it remains marked as closed in the records. The comprehensive renovations in 2016 addressed multiple aspects of the building's functionality, including bathroom facilities, HVAC systems, electrical infrastructure, and structural elements, suggesting a significant investment in improving the property's livability and safety features.
