Initial analysis

The two-unit residential building at 801 Wisconsin Street in Potrero Hill, owned by Wisconsin Property Holdings, has experienced several significant maintenance issues in recent years. Most notably, in late 2022, the property faced multiple violations and complaints regarding deteriorating exterior wood decks and stairways, with reports of dry rot creating safety concerns about potential collapse. These issues were documented through multiple housing inspections in October 2022, resulting in a Notice of Violation and subsequent repairs costing $6,500 completed in November 2022. The building's maintenance history shows attention to structural improvements, including a roofing project completed in 2004 and window replacements in 1997, indicating some level of regular upkeep.

More recently, in late 2023, there have been documented sewer-related issues, with two separate sewage backup incidents reported in November and December 2023, suggesting ongoing plumbing concerns. The building's historical problems included a sewage issue in 2001, though this was promptly resolved within five days. The property has also encountered various municipal service calls in the surrounding area, including reports of graffiti, abandoned vehicles, and garbage-related matters, though these are not directly related to the building's condition. While the structure has reached an age of over 116 years, recent records show efforts to address critical maintenance issues, though the recurring nature of some problems, particularly regarding sewer infrastructure, may warrant continued monitoring.

Risk rating

How 801 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.
