Initial analysis

The 4-unit, 2-story multi-family residential building at 2920 Polk Street in Russian Hill, owned by Darlene W Morishige Bypass, was constructed in 1959 and has undergone several significant renovations and maintenance work over its lifetime. In late 2008, the building underwent substantial improvements including window replacements, stucco renovation, and painting work costing $25,000, although this project later led to a building violation for exceeding the permitted scope of work related to sheathing and framing repairs. This violation was resolved by January 2009. The building's maintenance history shows attention to structural issues, with framing repairs and insulation work completed in late 2008 at an additional cost of $10,000.

Earlier renovations include a complete reroofing project in 1991, and in 1985 the building was brought into code compliance with an $870 investment. Recent activity around the property has primarily involved exterior maintenance issues, with several 311 calls in 2024 related to garbage and debris on the street and sidewalk areas. There was one instance of graffiti reported in September 2024, which was transferred to SFUSD for resolution. The building had routine housing inspections in 1996, 2003, and 2007, all of which were resolved without incident. A natural vegetation fire incident was recorded, but it was classified as an unintentional event with no civilian injuries noted. The property appears to be actively maintained, with most recent service requests being addressed and resolved appropriately.

Risk rating

How 2920 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, 510 are predicted to be safer.
