Initial analysis

The four-unit multi-family residential building at 1561 Filbert Street in Cow Hollow is a two-story apartment building constructed in 1924, currently owned by the David Hd Wong Survivors Trust. The building's maintenance history shows significant attention to roof maintenance, with reroofing work completed in 2009 at a cost of $16,000, following an earlier permit from 1992. However, more concerning was a cluster of fire safety violations discovered during a 2004 routine inspection, including issues with smoke detectors in stairways and the lobby, fire proofing materials, and the improper location of garbage receptacles. These violations, documented under complaint number 200449671, were all addressed and abated by May 20, 2004. Additionally, a 2010 routine inspection of common areas was conducted, which appears to have had no active violations. The most recent record related to the property is from 2022, concerning a street cleaning issue with loose garbage, which was resolved but indicates some ongoing maintenance challenges in common areas. The building's documented history suggests regular oversight and prompt addressing of violations when they occur, with no active violations on record since 2004.

Risk rating

How 1561 Filbert 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 861 buildings in this neighborhood, 508 are predicted to be safer.

Number of units

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

Estimated permit spend (past 7 years)

Moderate concern 14.0%
Severe concern 23.0%
