Initial analysis

The two-unit residential building at 2239-2241 Polk Street in Russian Hill, owned by Francis Chin, was constructed in 1907 and is classified as a two-story flat with a store. The property has undergone several significant renovations and faced notable challenges over its history. Most concerning was an August 2006 fire incident that led to multiple Notices of Violation, requiring substantial repairs including emergency electrical work to replace damaged circuits, fixtures, and devices. The building underwent significant accessibility improvements between 2006-2009, including the installation of accessible doors, handrails, guardrails, and new wash basins, in response to violation notices. More recent work includes a 2023 permit for improvements to comply with the accessible business entrance program, adding high/low push buttons for door operation.

The property has seen regular maintenance and upgrades, including a window replacement project in 2009, roof work in 2006, and various repairs to address building code compliance issues. Recent activity at the location has generated multiple 311 calls, primarily related to sidewalk cleaning, noise complaints, and occasional issues with street furniture, though most of these recent calls were not directly related to building safety or habitability. The building has maintained active compliance with local building codes since the resolution of the 2006 violations, with no recent serious safety concerns or building code violations on record.

Risk rating

How 2239-2241 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.
