AI summary

The property at 4216-4218 Balboa Street is a three-story multi-family residential building located in San Francisco's Outer Richmond neighborhood, owned by John Zi-jun Yang and Qian Sha. Built in 1954, this duplex underwent significant modifications in 1998-2001, including a completed $525,000 horizontal and vertical addition project and the installation of a $12,000 fire sprinkler system. During the construction period, there were multiple complaints related to the work, including concerns about noise, unauthorized construction of a wire fence, and interior demolition work without permits between December 2000 and October 2001, though these issues were addressed by the Building Inspection Division.

The property has experienced typical urban maintenance issues as documented through 311 calls, including street and sidewalk cleaning needs, graffiti removal, and utility line concerns between 2014 and 2023. The most recent maintenance-related issue was a missing street cleaning sign reported in July 2023, which was resolved. The building's documented history shows proper resolution of both construction-related issues and ongoing urban maintenance needs, with no recent complaints or violations recorded.

Risk rating

How 4216-4218 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

Out of 1040 buildings in this neighborhood, 52 are predicted to be safer.
