Initial analysis

The three-story, six-unit multi-family residential building at 2545 Polk Street in Russian Hill, owned by United Prosperity LLC, has undergone several significant improvements since 2012. Most notably, the building completed a mandatory $40,000 soft-story retrofit in 2017 (Tier 3) to enhance seismic safety, and more recent upgrades include the installation of washer, dryer, and hot water heater power in 2020, as well as kitchen and electrical improvements in 2019. The building underwent substantial renovations in 2014, including a comprehensive kitchen and bathroom remodel, electrical upgrades, window replacements, and furnace replacement, following a concerning complaint in September 2012 that noted multiple interior issues including deteriorating cabinets, electrical problems, and signs of water damage, along with environmental concerns regarding lead paint. These violations were all officially abated by November 2012. The property has maintained routine inspections over the years, and historical records show earlier issues including sewage backups in 1994 and 2000, stair damage repair in 1986, and a complete reroofing in 2008. Recent 311 calls from 2022 through 2024 primarily relate to street maintenance issues such as garbage cleaning and parking violations, though there was one documented carbon monoxide incident (with no civilian injuries) in the fire records.

Risk rating

How 2545 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.
