Initial analysis

The property at 1237 10th Avenue in San Francisco's Inner Sunset is a two-story, four-unit multi-family residential building constructed in 1924, currently owned by the Mae Shang Mar Revocable Trust. The building experienced significant maintenance issues in 2010, when a routine housing inspection resulted in multiple violations including the need for wall and window frame painting, repair of weather-proofing on exterior walls, replacement of broken glass window panes, and concerns about lead-based paint hazards. These violations, which temporarily defined the property as a nuisance under San Francisco Housing Code Section 1001(d), were notably serious but ultimately addressed and abated by August 2011.

The building's maintenance history shows some attention to basic upkeep, with records indicating reroofing work was attempted in 1997 (though this permit is now expired) and sidewalk repairs were permitted in 2010. More recently, the property has had minimal major concerns, with a few routine municipal service calls recorded between 2019 and 2022 primarily related to external issues such as illegal postings, parking violations, and a flickering streetlight, all of which were resolved through appropriate city departments. The last major housing inspection-related violation was over a decade ago, suggesting improved maintenance since the 2010 incident, though it's important to note that not all building conditions may be captured in public records.

Risk rating

How 1237 10Th Ave'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.
