Initial analysis

The two-unit residential building at 1648-1650 Leavenworth Street in San Francisco's Nob Hill neighborhood is a two-story flats and duplex structure built in 1909, currently owned by the Ho Family Revocable Trust. The building's documented improvements include an electrical upgrade in 2006 involving the installation of new lighting, circuits, and panels in the ground floor hallway, and the installation of twenty-seven aluminum windows in 1985. A street space permit was issued in 2005, though the specific nature and cost of this work are not indicated in the records.

The property has experienced several notable incidents, including three fire-related events: a contained cooking fire, a water-related issue, and a malfunctioning carbon monoxide detector activation, none of which resulted in civilian injuries. The building's surroundings have been the subject of multiple municipal service calls, primarily related to parking enforcement issues between 2018-2020, including multiple citations for illegal parking and one incident involving a blocked sidewalk by expired street space signs. Street cleaning-related complaints were made in late 2020, though two hazardous materials investigations (one for glass and one for loose garbage) resulted in no findings. The most recent service call was for an abandoned vehicle report in November 2024, which was resolved when the vehicle was no longer at the location upon inspection.

Risk rating

How 1648-1650 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.

Neighborhood percentile

Out of 1125 buildings in this neighborhood, 202 are predicted to be safer.
