Initial analysis

The property at 842-846 Guerrero Street is a 3-story multi-family residential building constructed in 1908, containing 7 units and currently owned by Rizzo Properties LP. The building has undergone several significant improvements over the years, most notably completing mandatory soft-story retrofit work in 2017 at a cost of $65,000, which included seismic upgrades and electrical improvements such as new plugs and switches. More recent maintenance includes plumbing work in 2023 with water heater replacement, and various roof-related work was proposed in 2022, though those permits were ultimately cancelled.

In early 2023, a notable incident occurred regarding construction work without proper permits, involving alleged unauthorized roof deck construction that resulted in violation notices, though this was eventually abated by April 2023. The building has a documented history of addressing maintenance issues, including two routine apartment inspections in 2002 and 2006, and a significant complaint from 2019 regarding unauthorized construction work and safety concerns about the back fire escape. While the property has undergone important structural improvements like the 2007 electrical service upgrade and 2017 seismic retrofit, a carbon monoxide incident and a false alarm were recorded in the fire incident history, though no civilian injuries were reported in either event. Recent months have shown multiple reports regarding street cleaning issues and illegal parking matters near the property, though these are external to the building itself and not directly related to resident safety.

Risk rating

How 842-846 Guerrero 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.
