Initial analysis

The property at 1541-1543 Leavenworth Street is a two-story, three-unit multi-family residential building located in San Francisco's Nob Hill neighborhood. Built in 1910 and classified as a Flats & Duplex building, it is currently owned by the Wong Family Trust Under Declaration. The building's permit history is minimal, with only one recorded permit in 2014 for street space usage with a nominal cost of $1.0.

The location has experienced recurring issues with street cleanliness and debris over the past 15 years, with a particularly notable concentration of incidents in recent years. Between 2020 and 2024, there were multiple documented cases of garbage and debris, including instances of human waste, needles, and general loose garbage. The most recent incidents occurred in late 2024, involving both human waste and needles on the street, though these were marked as closed cases with no work needed. While earlier cleaning incidents typically resulted in completed pickups or resolved cases, the nature of the recent complaints suggests potential concerns about neighborhood maintenance. The frequency of cleaning incidents has generally decreased since 2018, when there were multiple documented cases in a single year.

Risk rating

How 1541-1543 Leavenworth 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.
