The property at 850-854 Greenwich Street in San Francisco's Russian Hill neighborhood is a 3-story, mixed-use building constructed in 1928 containing 3 residential units and commercial space. The building has undergone significant recent improvements, including the conversion of a partial basement to two ADU units in 2019 at a cost of $159,000, followed by comprehensive fire safety upgrades in 2020, including the installation of a fire sprinkler system ($25,000) and fire alarm system ($12,000). Additional electrical work included upgrading the electrical service from 100 to 200 amps and installing new electrical systems in the newly created units.

The building's history includes several maintenance and compliance issues that appear to have been resolved. In 2017, there were serious concerns about a collapsing roof and various structural problems that required attention. Earlier violations from 2005-2007 involved unauthorized modifications, including illegal windows, an unpermitted roof deck, and lead paint concerns, though these issues were subsequently addressed through proper permitting and compliance actions. The most recent activity at the property has primarily consisted of routine building maintenance and parking enforcement issues, with several recent 311 calls regarding illegal parking in the vicinity of the building throughout 2024-2025.

Permitting history shows careful attention to building safety and modernization, with multiple final inspections completed in 2022 and various completed corrections in 2020-2022. The building's current condition appears stable, with no active violations or outstanding permits as of October 2023. Parking enforcement activity in the area has been notable, with multiple citations issued in recent months, though these are external to the building itself. The property's documented history suggests a proactive approach to addressing past violations and a focus on safety improvements through recent building modifications and systems upgrades.
