Initial analysis

The two-unit residential building at 1157 Kansas Street in Potrero Hill, owned by Gerard J Donnellan, is a two-story flats and duplex structure constructed in 1926. The property has undergone several significant improvements in recent years, including a comprehensive electrical system upgrade in November 2020 that included a 200-amp service upgrade, installation of unit sub-panels, and the addition of multiple dedicated outlets throughout both units. The building received a new roof in June 2022 at a cost of $19,500, and in 2019, important maintenance work was performed on the front brick facade, including repairs to angle irons and addressing leaking brick veneer. An earlier roofing project from 1993 is no longer active.

The property has experienced recurring maintenance issues with the surrounding infrastructure, particularly the sidewalk, which has shown multiple defects. Notable events include three separate reports of collapsed sidewalks between February and April 2019, though these were either not found to be hazardous or were resolved through inspection. More recent concerns include a defaced sign in November 2023, graffiti on the sidewalk in October 2023, and an open sidewalk defect report from October 2023. The building's immediate area has also experienced periodic issues with illegal parking on the sidewalk, with reports in February 2023 and August 2019. The property has been maintained actively by its owner, with all building permits showing "Complete" status, indicating proper adherence to regulations and successful completion of the work.

Risk rating

How 1157 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.
