Initial analysis

The two-unit residential building at 2229-2231 Balboa Street in San Francisco's Central Richmond neighborhood is a two-story flats and duplex structure owned by Stanley Yeung and dating back to 1947. The building's maintenance history includes several significant events, particularly a concerning cluster of sewage backup incidents in November 2018, with three separate occurrences involving a 4-inch vent line that required multiple response interventions by PUC Sewer Operations to address grease-related blockages. The property has undergone some improvements over the years, including a street space permit in 2015, though two historical permits for reroofing (1999) and aluminum window installation (1987) are listed as expired.

The recent history of the property shows a range of neighborhood maintenance and safety issues, particularly in 2019-2020, including multiple instances of sidewalk parking violations, a non-offensive graffiti incident on a pole, and tree-related concerns. There was a damaged tree case in May 2020 that was addressed through regular maintenance scheduling, and a weeding matter reported in August 2021 that remains open as of the latest available data. During the early months of the COVID-19 pandemic, there was at least one recorded encampment situation near the property that was handled in accordance with CDC guidelines. While the building has faced various neighborhood challenges, particularly related to public space usage and landscape maintenance, the most critical infrastructure issues (the 2018 sewer problems) appear to have been resolved at that time, and there have been no recent reports of similar plumbing issues.

Risk rating

How 2229-2231 Balboa 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.
