The two-unit residential building at 831-833 27th Avenue in the Central Richmond neighborhood, owned by Tom Carrol Li, has undergone several significant renovations since its construction in 1987, including comprehensive updates in 2019 and a recent sewer-related incident in October 2024. The most substantial work occurred in October 2019 when both units received major interior renovations valued at $140,000, including kitchen and bathroom upgrades, along with the installation of new electrical systems featuring modern appliances and fixtures. The building has also experienced some maintenance issues, particularly with sewer infrastructure, as evidenced by three sewer-related incidents between 2021 and 2024, with the most recent case involving a sewage back-up discharge from a side sewer vent.

Other historical improvement work includes a roofing project from 2003 and various utility updates, though these were mostly completed or expired many years ago. The property has been generally well-maintained, with the most recent major works focusing on updating windows and modernizing living spaces. The building's infrastructure improvements in 2019-2020 included comprehensive electrical and plumbing upgrades, indicating proper maintenance of essential systems.

While there have been some infrastructure issues, particularly related to sewer systems, these cases have been resolved through proper channels. The property's maintenance history shows regular upkeep, with the most substantial work occurring approximately every decade, including the recent windows and interior renovations. The building's location near a park has resulted in some external maintenance matters being recorded, though these primarily relate to park activities rather than the building itself.
