Initial analysis

Located in San Francisco's Russian Hill neighborhood, 2750 Polk Street is a 3-story, 6-unit multi-family residential building constructed in 1923 and currently owned by Fosse Lvg Tr. The building has undergone several significant safety system upgrades in recent years, with the most notable being a comprehensive fire alarm system upgrade completed in 2023 that included installation of low-frequency sounders in sleeping areas and compatibility updates to meet current fire codes. Other recent major improvements include a backflow replacement in 2021 and a boiler replacement in 2017, demonstrating ongoing maintenance of essential systems.

The building's history includes several concerning maintenance issues, particularly during the 2006-2009 period, when multiple complaints were filed regarding inadequate heat, water leaks, electrical problems, and window issues. A troubling incident in 2006 involved exposed electrical wires and a reported fire hazard. The building has also experienced recurring issues with water penetration and window problems, as evidenced by complaints in 2020 and 2006. While many past violations were abated by 2007, and recent years show fewer maintenance complaints, there have been ongoing concerns about parking issues in the vicinity, as evidenced by multiple parking enforcement requests in 2024. The building's fire safety systems have required attention over the years, with multiple fire alarm complaints in 2008 that were resolved, though recent improvements suggest better current compliance. The most recent service calls primarily relate to external issues rather than building systems, including streetscape maintenance matters.

Risk rating

How 2750 Polk 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.

Neighborhood percentile

Out of 1133 buildings in this neighborhood, 702 are predicted to be safer.
