Initial analysis

The 15-unit multi-family residential building at 1670 Sutter Street, built in 1978 and currently owned by Weston Real Estate Partners, has experienced several significant maintenance and safety-related events over its history. Most recently, in November 2023, a building-wide complaint was filed regarding potential seismic safety concerns and possible soft-story ordinance non-compliance, though Technical Services Division later confirmed the building is exempt from the mandatory soft-story program. The building has undergone various infrastructure improvements, including balcony repairs in 2011 ($20,000), a sidewalk repair in 2005, and a complete reroofing in 1991. Electrical work was performed in 2012 to relocate wires in multiple units (104, 204, 105, and 205).

The property has a documented history of routine housing inspections in 1999 and 2011, and several fire safety inspections between 2007 and 2024, with most being determined to have "No Merit" or showing "Condition Corrected" status, indicating prompt attention to identified issues. There have been three confirmed fire safety incidents related to the alarm system (2007), extinguishers (2016 and 2019), and other safety systems (2021), with no civilian injuries reported. Recent external maintenance issues have included graffiti removal and tree root management (2021), and there have been multiple parking enforcement actions related to driveway blocking in 2022-2024, though these are not directly related to building conditions. The building's management has maintained response to various building and public space issues, as demonstrated by the resolution of most reported problems through appropriate channels.

Risk rating

How 1670 Sutter 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 670 buildings in this neighborhood, 596 are predicted to be safer.
