Initial analysis

The property at 1662-1666 Chestnut Street is a two-story, three-unit multi-family residential building located in San Francisco's Marina neighborhood. Built in 1900 and currently owned by the James S Leong Revoc Trust, this flats and duplex-style building has experienced several notable maintenance and compliance issues in recent years. Most significantly, in May 2024, the building received multiple violations related to weather protection and lead abatement procedures, though these were promptly addressed and officially abated by June 14, 2024. The building's maintenance history includes a reroofing project from 1995, though that permit has since expired.

The property has seen a range of neighborhood-related issues and service requests over the past decade, including illegal postings (2021), graffiti (2020), and various street maintenance concerns such as a faulty manhole cover (2018) and a flickering streetlight (2014) - all of which have been resolved. In 2015, planning records indicate that a variance was approved for the addition of a single-family unit at the front of the lot, though there are no subsequent records of this modification being implemented. The most recent noted issue prior to October 2023 was the exterior condition of the building, with visible peeling paint being reported from the street view in May 2024, which contributed to the subsequent building violations.

Risk rating

How 1662-1666 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
26th percentile

Out of 988 buildings in this neighborhood, 731 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.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

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 32.5%
Moderate concern 29.8%
Severe concern 37.7%
