Initial analysis

The property at 1140-1142 South Van Ness Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Inner Mission neighborhood. Built in 1885 and owned by Nobuo Yamaji, this flats & duplex structure experienced a significant fire incident in September 2008 that caused considerable damage requiring extensive repairs. The fire led to the replacement of 6 exterior wall studs, 6 roof rafters, approximately 1200 square feet of sheetrock, interior finishes, wiring, and a portion of the roofing, with repair costs estimated at $150,000. The building underwent various permits and inspections between 2008 and 2010, including the installation of a new 100-amp electrical service, rewiring of affected areas, plumbing work in unit 1142, and the addition of a roof-mounted solar panel system.

More recently, between October 2024 and January 2025, there have been numerous reports (seven in total) of garbage and debris on or near the property, with various agencies responding to address these issues. These incidents included reports of bagged garbage, debris, a Christmas tree, and even hazardous waste and human waste/urine in the vicinity. While most of these cases were resolved promptly, with some requiring no work, the frequency of recent sanitation-related issues is notable. The building's maintenance record shows regular street space permits issued in 2008-2009, and a fire alarm system complaint was filed and closed in April 2008 with no merit found. The most recent building-related permits were completed in 2010, indicating there have been no major structural modifications or repairs in the past decade.

Risk rating

How 1140-1142 South Van Ness 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.
