Initial analysis

The three-story, six-unit apartment building at 624-628 South Van Ness Avenue, owned by Athena Wong, was constructed in 1908 and has undergone several significant events throughout its history. Most notably, the building completed its mandatory Soft Story Retrofit Program requirements, receiving a Certificate of Final Completion (CFC) as a Tier 3 property. Recent building improvements include the replacement of a damaged sidewalk house trap in 2011 and attention to some unit-specific issues, such as electrical outlet repairs in 1986 (though this permit was ultimately cancelled). The property has experienced recurring maintenance issues over the years, with several building violations documented in 2023 related to fire safety equipment and gas meter requirements, all of which were abated within a two-month period.

Historical maintenance challenges have included multiple staircase repairs, including the rebuilding of damaged side stairs in 2003, and various habitability concerns such as flooding issues in 1996 and a kitchen-related complaint in 1996 that documented water intrusion, mildew, and electrical problems. The building's common areas have required attention to lighting (2007) and various fire safety compliance issues (2014). Recent maintenance efforts appear to be more focused on addressing fire safety and earthquake retrofitting requirements, with a completed soft-story retrofit improving the building's seismic safety. The property has also experienced periodic issues with graffiti, as evidenced by multiple 311 calls in 2023-2024, though these were generally resolved through standard city procedures. While the building's age suggests ongoing maintenance requirements, the completion of the soft-story retrofit program indicates compliance with one of the city's major seismic safety initiatives.

Risk rating

How 624-628 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.
