Initial analysis

The property at 819 South Van Ness Avenue is a two-story, four-unit multi-family residential building located in San Francisco's Inner Mission neighborhood. Built in 1980 and currently owned by Wong Jack W & Ruby J Revoc, this Class A apartment building has undergone several significant exterior renovations over the years. The most recent major work, completed in 2013, involved replacing wood shingles with Hardi Shake siding on the front facade and installing vinyl siding on the back of the building at a cost of $30,000. Earlier improvements include a steel siding application in 1987 and reroofing work in 1992.

The building has experienced periodic routine housing inspections, with the most notable violations occurring during a 2015 inspection when water heater bracing and affidavits were required, though these issues were promptly abated within one month. Historical complaints from 1994-1995 indicate past maintenance concerns, including bathroom and hallway floor issues in Unit #4 and water leakage problems in Unit #2, as well as a vagrancy situation that required attention. More recent 311 calls from 2017 to 2024 have primarily involved street-related issues such as pavement defects, garbage, and parking enforcement matters, though these are not direct building concerns. Additionally, the property is associated with a T-Mobile wireless equipment installation on an SFMTA steel light pole, which was approved and closed in the planning records.

Risk rating

How 819 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
91th percentile

Out of 2380 buildings in this neighborhood, 214 are predicted to be safer.
