Initial analysis

The two-unit residential building at 645 Kirkham Street in San Francisco's Inner Sunset neighborhood is a 2-story flats and duplex structure built in 1914 and currently owned by the Chak Kuen Lee Trust. The property's maintenance record shows several significant events, with the most notable being a building violation in late 2016 when unauthorized trash enclosures were constructed in front of the property, encroaching on the sidewalk and requiring municipal intervention and removal. This violation was promptly addressed within days of being reported, and the illegal structures were removed by November 9, 2016. The building's infrastructure has seen some updates over the years, including a completed electrical upgrade in 2003 that installed a 200-amp main service with two meters and panels, and a plumbing permit from 2018 for house trap replacement, though this permit has since expired. Two other permits are on record, including a street space permit from 2019 costing $1, and a $500 permit related to the 2016 trash enclosure violation.

The property has experienced recurring issues with abandoned vehicles in the vicinity, with several reports filed between 2009 and 2019, though these are external to the building itself and were handled by the Department of Transportation. These vehicle-related incidents were consistently resolved when no vehicles were found at the time of inspection, indicating that they were likely temporary issues rather than ongoing concerns. The building's recent permit activity has been minimal, with no major renovations or repairs documented in the past few years, though the electrical system upgrade from 2003 suggests that basic utility infrastructure has been previously modernized.

Risk rating

How 645 Kirkham 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
61th percentile

Out of 1493 buildings in this neighborhood, 582 are predicted to be safer.
