Initial analysis

The three-story, six-unit multi-family residential building at 1670 Chestnut Street in the Marina district, owned by Peter B A & Sophie Pappas, has a documented history of maintaining compliance with mandatory seismic safety requirements. The building completed its soft-story retrofit program under SFBC Chapter 4D, with work starting in 2017 and completing in early 2024, following multiple permits including one for a new steel frame installation. The building has undergone various structural improvements over the years, including a significant earthquake damage retrofit in 1990, and routine maintenance such as roofing work in 1996 and water heater replacement in 2010.

Recent building inspections have revealed several maintenance issues requiring attention. As of 2024, there are active complaints regarding peeling paint on the west exterior, weather protection needs, and lead abatement procedures. Historical complaints have documented various safety concerns, including damaged stairs (2020), garage door issues (2024), and a prior violation regarding soft story compliance (2019). The building has experienced four fire-related incidents, though all were either false alarms or related to system malfunctions with no civilian injuries reported. While the property has generally adhered to major safety requirements, the recent active violations suggest ongoing maintenance challenges that may affect resident comfort and safety.

Risk rating

How 1670 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.
