Initial analysis

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.

Risk rating

How 850-854 Greenwich St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.
