Initial analysis

The property at 531 Fillmore Street in Hayes Valley is a two-unit, two-story multi-family residential building built in 1900, currently owned by Wilson Hu and Agnes Toan. The building's history includes several significant events, most notably a fire incident in 1999 that required substantial repairs to the upper unit, roof, and walls, along with the installation of fire-rated parapets. The building is currently undergoing modifications as of January 2024 to legalize an existing housekeeping unit in the attic as an ADU, which includes necessary fire safety improvements such as 1-hour fire separation and fire coating applications in the upper unit ceiling. This project will also involve reworking gas piping from the meter area to the maintenance/house unit.

The property had an incident in 1997 involving two complaints about alleged illegal units and concerning occupants, though these cases were abated within weeks and marked as not active. Between 2021 and 2024, there have been multiple maintenance and environmental issues documented through 311 calls, primarily relating to parking violations (including sidewalk parking), general street cleaning needs, and minor graffiti, all of which were resolved through appropriate channels. The building's records show consistent attention to regulatory compliance, with the most recent permits demonstrating ongoing efforts to bring the property into full legal compliance with current housing regulations.

Risk rating

How 531-533 Fillmore 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 1027 buildings in this neighborhood, 154 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.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

12-Month severity forecast
No violation 78.6%
Moderate concern 13.3%
Severe concern 8.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
