Initial analysis

The two-unit residential building at 1391 37th Avenue in the Outer Sunset district, owned by the Chan Family Trust, has a documented history spanning several decades since its construction in 1945. Significant unauthorized construction activity was reported in 2021, with complaints about nighttime work occurring without proper permits. In 2010, there were multiple housing code violations related to interior conditions, including issues with lead-based paint, damaged ceilings and walls, mold/mildew, plumbing problems, and window repairs, all of which were abated by October 2010. The building underwent two notable permitted improvements: a ground floor bedroom and family room addition in 2010, and the construction of a storage room and bathroom in the basement in 1994.

The property has experienced recurring concerns about potential unauthorized dwelling units, with investigations in 2010 and 2012 regarding possible illegal basement and garage units. Historical complaints from 1994 also indicated issues with hot water availability. More recently, in late 2024, there have been multiple reports (over ten in December alone) regarding overflowing city garbage cans and debris on the street, though these are external sanitation issues and not directly related to the building's condition. While the major historical violations have been resolved, the building's record shows a pattern of unauthorized modifications and maintenance issues that required regulatory intervention, particularly in the early 2010s.

Risk rating

How 1391 37Th Ave'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.
