Initial analysis

The three-unit residential building at 1243-1247 Leavenworth Street in Nob Hill, owned by Chuen Mei Wong Family Trust, was constructed in 1908 and is classified as a Flats & Duplex building over three stories. The property's most significant historical renovation occurred in late 2000, when comprehensive updates were undertaken to remodel kitchens and bathrooms, along with addressing dry rot issues and clearing termite reports, with a total project cost of $40,000. More recently, there have been several maintenance and property-related issues in 2023-2025, including multiple reports of garbage and debris (both loose items and abandoned furniture) on the street, repeated illegal parking complaints, and incidents of illegal postings and graffiti on public property. A noise complaint regarding construction on private property was filed in October 2023, and records show a routine housing inspection complaint from 2003 that was abated in 2007. The building's documented history shows regular street maintenance issues typical of urban environments, though no significant safety incidents have been reported, and there is no record of civilian injuries or fire incidents associated with the property.

Risk rating

How 1243-1247 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
75th percentile

Out of 1125 buildings in this neighborhood, 281 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

12-Month severity forecast
No violation 40.8%
Moderate concern 15.6%
Severe concern 43.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
