Initial analysis

The two-unit residential building at 823 Kansas Street in Potrero Hill is a two-story flats and duplex structure built in 1908, currently owned by trustees Clifford and Bernice Wong. The property has undergone several significant improvements over the years, including a complete reroofing project in 2019 costing $15,000, and a major horizontal extension and renovation of the top unit completed in 1987. The street spaces permit from 2017, though minimal in cost, indicates attention to public space management.

The building has experienced recurring sewer issues, with five documented sewage backup incidents between 2011 and 2020 specifically involving 4-inch sewer vents, though most of these cases were resolved through municipal intervention. There was also one instance of sidewalk collapse reported in 2018 that remains open as of the latest data. Other maintenance issues included street lighting problems, with two documented cases in 2011 showing a flickering light and a burnt-out bulb, both of which were successfully addressed through repairs. While the building's infrastructure has required regular attention to maintain basic services, most issues have been promptly resolved by appropriate city departments or through proper permits, suggesting the owners take necessary steps to address building maintenance needs when they arise.

Risk rating

How 823 Kansas St'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
