Initial analysis

The property at 1040 Wisconsin Street in Potrero Hill is a two-unit, two-story multi-family residential building constructed in 1900, currently owned by Morris Dianne Rev Liv Trust. The building has experienced several significant infrastructure issues over the years, most notably between late 2006 and early 2007 when there were serious sewage leakage problems affecting both the property's sewer line and neighboring properties, requiring multiple notices of violation before being abated in February 2007. More recently, in 2017, there was an active complaint regarding insects/rodents, damaged walls, and accessibility issues related to property overgrowth and debris, as well as reported issues with path of travel access.

The building has undergone various safety and infrastructure improvements, including the installation of a fire alarm system in 1996 (now expired), a small wall heater installation in 2021, an electrical service correction in 2008, and attempted upgrades to the electrical panel in 2007 (though this permit was cancelled). Two fire alarm system complaints were recorded in 2009 and 2010, but were promptly corrected. More recently, there have been multiple parking-related complaints in the vicinity, including several cases of blocked driveways and double parking between 2023 and 2024, though these are external to the building itself. The property has also required attention to hazardous materials on the street/sidewalk area, with two incidents reported in 2023 involving glass and liquid substances, both of which remain open as of 2024.

Risk rating

How 1040 Wisconsin 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.
