Initial analysis

The six-unit multi-family residential building at 1401 Chestnut Street in the Marina neighborhood, owned by Cbj Family Ltd Partnership, has undergone several significant improvements since its construction in 1923. The property completed mandatory safety upgrades including a fire alarm system modification in 2020-2021 to comply with San Francisco fire code requirements, and successfully finished a soft-story seismic retrofit of the garage in 2016, receiving its Certificate of Final Completion. Other substantial improvements include a complete reroofing project in 2018 and an electrical service upgrade in 2015, which involved installing a new 400-amp underground service with seven meters serving both residential units and common areas.

The building's maintenance and safety record shows regular attention to required upgrades, though there have been numerous recent 311 calls in the vicinity, primarily related to encampments, street cleaning, and municipal transportation issues between 2024 and 2025. While these external neighborhood issues do not directly impact the building's internal systems or safety, they indicate some ongoing urban challenges in the immediate area. A routine safety inspection in 2016 by Housing Inspection Services is noted as not active, suggesting no significant violations were found, and the building's documented improvements demonstrate compliance with current safety standards.

Risk rating

How 1401 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
36th percentile

Out of 988 buildings in this neighborhood, 632 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.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Neighborhood location

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

Property class: multi-family flat

2–4 unit flats (class F) are a common SF building type with their own maintenance and complaint patterns.

12-Month severity forecast
No violation 46.8%
Moderate concern 25.4%
Severe concern 27.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
