Initial analysis

The three-unit, two-story multi-family residential building at 2231-2235 Polk Street in Russian Hill, owned by the Song 1999 Family Trust, was constructed in 1924 and has undergone several significant modifications and faced various challenges over the years. Most recently, in October 2024, the property initiated a major accessibility upgrade to install ADA-compliant restroom facilities, including new toilet and sink fixtures, grab bars, mirrors, and accessible signage, along with modifications to the entry door for improved accessibility. The building has received regular maintenance attention, including a $9,000 reroofing project in 2022, a 200A electrical system upgrade to three-phase service in 2004, backflow assembly replacement in 2017, and the removal of a plumbing hazard in 2023. Historical issues include a 2004 complaint regarding inadequate heating and hot water, as well as concerns about gas/electrical meter configuration, though these were resolved by mid-2005. A more recent and concerning active complaint from 2003 remains on record regarding unauthorized dry cleaning operations in the garages.

The property has experienced various maintenance and environmental challenges in recent months, particularly noticeable in early 2025, with multiple reports of abandoned furniture, mattresses, and garbage on the property. There were also parking enforcement issues near the building in January 2025, though one was not validated by responding officers. Previous building modifications include a 2007 wall sign installation ($21,000), garage door frame replacement in 2001, and garage door opening modifications in 1996, though some of these permits expired. The building has had two fire-related incidents on record, neither resulting in civilian injuries, and experienced graffiti requiring cleanup in December 2024. The property's recent focus on accessibility improvements and regular maintenance suggests ongoing investment in infrastructure, though the accumulation of debris and abandoned items around the property has been notable in recent months.

Risk rating

How 2231-2235 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.
