Initial analysis

The Wong Family Trust owns this three-unit multi-family residential building located at 40-44 Dearborn Street in San Francisco's Mission Dolores neighborhood. Built in 1908, the three-story flats and duplex structure has undergone several significant maintenance and improvement projects over the past two decades. Most recently, in 2016, the building received a new roof at a cost of $8,000. Between 2004 and 2005, comprehensive window upgrades were completed, including the installation of 24 replacement windows, with the earlier project involving 9 non-street-visible windows.

The property has maintained a generally good maintenance record, with three routine housing inspections in 2001, 2006, and 2011 resulting in no violations. Recent activity includes a Rent Board inquiry in November 2023 regarding fee housing inventory. The building's external environment has experienced typical urban challenges, including several incidents involving trees (2020), parking violations (2020-2022), and sidewalk maintenance issues such as waste removal (2018-2021) and graffiti (2016). These external issues have all been promptly addressed by responsible city departments, including the Department of Public Works and Parking Enforcement. One notable incident occurred in March 2024 involving damaged property, which was serious enough to warrant a transfer to 911 services, though no further details are available in the public record.

Risk rating

How 40-44 Dearborn 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
