Initial analysis

This three-story, three-unit multi-family residential building located at 1375 Chestnut Street in the Marina neighborhood was built in 1982 and is currently owned by Ronald C. & Marian Won 1985. The property has experienced several significant issues over its history, most notably a cluster of fire safety violations in January 2004, which included multiple egress obstructions, problems with the fire escape drop ladder, fire extinguisher maintenance issues, and concerns regarding gas meter safety requirements. While these violations were all marked as "Not Active" after June 25, 2004, indicating they were addressed, they represent a period of notable safety concerns. In September 1999, the building underwent a renovation involving the installation of vinyl siding on the side wall.

The most recent complaint filed against the building was in September 2024, regarding peeling paint on the slab below a door closer, though this was designated as "Not Active." Since August 2024, there have been multiple issues with parking enforcement, with several citations issued for blocked driveways, particularly in November 2024. There have also been recurring concerns about garbage and debris, with multiple service requests submitted to street and environmental services between October and November 2024. A carbon monoxide detector activation occurred at the property with no confirmed CO presence, and no civilian injuries were reported. A recent inspection in September 2024 had the additional note for further inspection of the entire front exterior for potential code violations.

Risk rating

How 1375 Chestnut 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
72th percentile

Out of 988 buildings in this neighborhood, 277 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.

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.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

12-Month severity forecast
No violation 63.2%
Moderate concern 19.4%
Severe concern 17.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
