Initial analysis

The two-unit multi-family residential building at 58 Williams Avenue in the Bayview neighborhood is a one-story flats and duplex structure built in 1911 and currently owned by Wei Hai W. The property's documented history shows relatively few incidents or maintenance issues over the past several decades. The oldest record dates back to 1988 when there was an attempt to correct records related to the two-flat building, though this permit was ultimately cancelled. In 2008, a street space and sidewalk permit was issued for what appears to be a minor improvement or maintenance matter with an exceptionally low cost of $1.00.

More recent records of concern have primarily involved routine municipal matters rather than building-specific issues. A missing side sewer vent cover was reported and resolved in February 2013, with documentation confirming that the cover was recently replaced with no further action required. In 2019, there was a report of waste receptacles being left out continuously, though this was addressed and resolved upon investigation. The most recent incident occurred in January 2025 involving illegal parking near the property, but responding officers were unable to locate the reported violation. While these incidents reflect typical urban living challenges, none have indicated any significant structural or safety concerns with the building itself.

Risk rating

How 58 Williams 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.

Neighborhood percentile
61th percentile

Out of 382 buildings in this neighborhood, 149 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.

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.

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

12-Month severity forecast
No violation 72.7%
Moderate concern 17.2%
Severe concern 10.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
