The two-unit residential building at 634-636 South Van Ness Avenue, constructed in 1908, has undergone several significant improvements and modifications over recent years under the ownership of Huie Fritz C & Yan Yi. Most notably, in 2020, the property received comprehensive fire safety upgrades, including the installation of a new fire alarm system (cost: $7,500) and a ground floor fire sprinkler system ($10,000), with associated electrical work and multiple monitoring devices.

The building underwent substantial interior renovations in 2019, including the addition of a new kitchen, bedroom, and bathroom on the first floor, as well as similar additions on the third floor, and the enclosure of a lightwell on the second floor (total cost: $195,000).

However, significant recent improvements include a complete replacement of the rear egress stair in 2017 to meet safety requirements, and various bathroom and kitchen remodeling projects in multiple units. The property has also seen attention to infrastructure improvements, including plumbing system upgrades and new electrical systems throughout.
