Initial analysis

The 7-unit, 3-story apartment building at 2747 Polk Street in Russian Hill, owned by Fosse Lvg Tr, was constructed in 1924 and has undergone several significant safety and infrastructure upgrades in recent years. Most notably, the building completed mandatory soft-story retrofit work in 2017 (Tier 3) at a cost of $150,000, followed by a revision in 2019 to replace plywood shear walls with hardy panels. In 2022, the fire alarm system was upgraded to comply with San Francisco fire codes, including the installation of low-frequency sounders, and an annual backflow device replacement was completed in December 2022. The building has maintained its basic systems with a steam boiler replacement in 2016, and regular unit updates including a comprehensive kitchen and bathroom remodel in Unit A in 2015.

The property has experienced several routine inspections and minor violations throughout its history, primarily relating to fire safety systems, including multiple alarm system complaints that were promptly corrected between 2009 and 2017. In 2016, there was a boiler permit renewal issue that was resolved within three months. While the building and its systems have generally been well-maintained, the surrounding area has experienced periodic issues such as sidewalk cleanliness concerns, documented through multiple 311 calls between 2019 and 2024, though these were primarily external to the building itself. The most recent maintenance issues have been primarily related to exterior conditions, including a graffiti incident reported in May 2024 and various cleaning matters that have been consistently resolved by city services.

Risk rating

How 2747 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.
