Initial analysis

The property at 2428-2432 Polk Street is a two-story multi-family residential building located in San Francisco's Russian Hill neighborhood, constructed in 1979 and containing three residential units plus a retail space. The building, currently owned by Penelope A. Clark, has maintained an active regulatory footprint over the years, with several significant events and permits on record. The most recent notable incident occurred in November 2022, involving a collapsed sidewalk situation that required attention to address missing service utility vault cover inserts, though this was ultimately resolved.

The building's permit history is relatively minimal, with a notable address assignment in 2004 and several planning-related actions in recent years. These include approved applications for Cottage Food Operator status with the Department of Public Health, a DPW referral (21WR-00015), and wireless equipment installation for AT&T Mobility on a PG&E light pole, which was documented under ExteNet Systems. Past minor issues have included a 2016 complaint about improperly stored trash toters, which was investigated but resulted in no findings. While the building has had its share of typical urban maintenance issues, particularly regarding public infrastructure like sidewalks, most recorded incidents have been resolved through normal city processes.

Risk rating

How 2428-2432 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
