Initial analysis

The property at 2431 Balboa Street is a two-unit, one-story multi-family residential building located in San Francisco's Central Richmond neighborhood, owned by the Kin M & Angela Y Lam Revocable Trust and constructed in 1917. The building has undergone several significant modifications throughout its history, most notably a vertical addition completed in 1997, which followed earlier attempts for both vertical and horizontal expansions in 1990-1991 that ultimately expired. More recently, the property has faced some maintenance challenges, particularly with recurring flooding issues, with three separate incidents requiring PUC Sewer Operations response between late 2022 and 2023. Another noteworthy concern is an unresolved sidewalk defect reported in February 2022, which may impact pedestrian safety.

The building's record also shows various urban maintenance issues typical of its location, including parking enforcement calls regarding blocked driveways (most recently in August 2024), illegal postings (April 2022), overflowing city garbage cans (April 2022), and a graffiti incident (July 2020). The property's planning records indicate a review process for wall replacement and a successful third-story addition approval, demonstrating the owners' commitment to improving the property despite historical challenges with obtaining proper permits. While the recent flooding incidents and sidewalk defect require attention, the building's overall permit history suggests significant improvements have been made over time.

Risk rating

How 2431 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.

Neighborhood percentile
66th percentile

Out of 2250 buildings in this neighborhood, 765 are predicted to be safer.
