Initial analysis

The three-unit residential building at 873-877 Union Street in Russian Hill, owned by FFA 873 LLC, has undergone significant safety and modernization improvements since 2019. Notable recent improvements include a comprehensive fire safety upgrade in 2020 featuring the installation of a new fire alarm system with sprinkler monitoring and the complete installation of a fire sprinkler system across all three floors, representing an investment of approximately $33,000 in life-safety improvements. The building has also received substantial unit improvements including three-bedroom unit remodels with new bathrooms, kitchens, and mechanical systems (water heaters and furnaces) completed in mid-2020, and earlier in 2019, there was a comprehensive electrical upgrade including a new 400-amp service.

The property had historical fire safety compliance issues that were addressed in 2005 through a routine inspection, which identified various fire safety concerns including smoke detector and fire extinguisher requirements, though these were promptly abated by June 2005. There were also significant renovation activities in 2019-2020, including a notable complaint about construction work continuing during the shelter-in-place order, and earlier complaints about unpermitted work, though these issues were marked as not active. The building's mechanical systems have been maintained, with a backflow device replacement completed in 2022 and water heater replacements in 2020, though there was also a record of multiple plumbing and electrical upgrades and repairs between 2017-2022. The most recent records from 2024 show typical urban maintenance issues in the vicinity, such as sidewalk blockages and parking violations, which were resolved through normal city processes.

Risk rating

How 873-877 Union 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.
