Initial analysis

The 12-unit, 3-story multi-family residential building at 2459 Polk Street in Russian Hill, built in 1923, has undergone several significant safety and infrastructure improvements over the past two decades. Most recently, in May 2024, the building completed a major upgrade to its fire alarm system, including the installation of low-frequency sounders in sleeping areas to meet current code requirements, with associated electrical work. The building achieved compliance with San Francisco's soft story retrofit requirements in 2016, and has undergone multiple safety-related upgrades including the replacement of 130 windows in 2006, and various HVAC improvements such as water heater and wall furnace replacements in 2016 and 2009.

The property has a documented history of maintenance and safety compliance efforts, though there have been some notable issues requiring attention. In 2021, Unit 9 reported significant concerns including mold, ceiling leaks, and structural problems attributed to roof issues, while a 2016 complaint documented problems with water quality. The building had several code violations issued in 2009 related to electrical permits, smoke detection systems, plumbing issues, and water damage, all of which were ultimately abated by December 2009. The most recent building inspection records show ongoing attention to infrastructure maintenance, including repairs to drainage systems and various building systems. Recent 311 calls from 2023-2024 primarily relate to street-level issues such as garbage removal and parking enforcement, as well as one construction noise complaint in October 2024, which was associated with valid night work permits for public improvements on Polk Street.

Risk rating

How 2459 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
