The two-unit multi-family residential building at 405-407 42nd Avenue in San Francisco's Outer Richmond neighborhood, owned by Vladimir Panarin, has undergone several significant infrastructure upgrades since its construction in 1948. The property has seen consistent maintenance of essential systems, with the most recent major work occurring in 2017 when both water heaters (40-gallon units) and the furnace were replaced. Prior to this, the building had several important repairs, including a sewer repair in 2012 and a lightwell stairs repair in 2008.

Earlier maintenance work included reroofing in 1995. The building has experienced some notable issues impacting resident comfort and safety. In 2016, there were reports of a collapsed sidewalk affecting approximately 100 square feet at 407 42nd Avenue, along with 10 linear feet of damaged curb, which required attention from the Department of Public Works.

A hazardous materials incident involving unknown liquids was reported and resolved in December 2016. The building's plumbing history includes a complaint from 1999 regarding unauthorized water heater installation, though this was resolved within two months. Recent activity at the property has been minimal, with only routine municipal service calls recorded in 2020 (illegal postings) and 2023 (parking enforcement). The building's maintenance record shows regular upkeep of critical systems, with no current active violations or complaints on file.
