AI summary

The property at 977-981 South Van Ness Avenue is a two-story, three-unit multi-family residential building located in San Francisco's Inner Mission neighborhood, constructed in 1900 and currently owned by the Yngojo-wang Family Trust. The building has undergone several significant modifications and maintenance work over the past few decades, including window replacement in 2003 costing approximately $12,143, and a plumbing upgrade in 2014 involving shower pan installation and related work. Historical permits from the 1980s indicate more substantial alterations, including a horizontal extension and new stair installation (1986), and fire sprinkler installation for the driveway and back cottage (1987), though these permits are listed as expired. An earlier remodeling project from 1994 aimed to renovate a third-floor bathroom and make several other interior improvements, but this permit also expired.

The building's recent maintenance history includes several street-level and sidewalk-related incidents recorded through 311 calls, though these primarily involve external factors rather than building-specific issues. These calls included reports of sidewalk parking (2023), graffiti on a retaining wall (2022), and hazardous materials and waste on nearby streets (2017 and 2015). While these incidents have been resolved through appropriate city departments, they mainly reflect urban neighborhood challenges rather than direct impacts on the building's condition or safety. The most recent building-specific work records date back to almost a decade ago, with no major structural or systems upgrades noted in recent years.

Risk rating

How 977-981 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.

Neighborhood percentile

Out of 2380 buildings in this neighborhood, 1095 are predicted to be safer.
