Initial analysis

The three-story multi-family residential building at 930-934 Union Street in Russian Hill, built in 1927, is a four-unit flats and duplex property currently owned by Madeline Torre Tr. The building's documented history shows several routine inspections by Housing Inspection Services, most notably in May 2005, which resulted in temporary violations related to emergency exiting and smoke detectors - all of which were promptly resolved within one day of being filed. Prior to those, there was another routine inspection in March 2000 that did not result in any violations.

The property has undergone some maintenance work, including a $16,000 reroofing project in 2005 (though this permit has since expired) and the installation of a manufactured stairway in 1988, which was completed successfully. Recent issues outside the building have mostly centered around typical urban maintenance matters, with the most recent incident being a furniture removal case in July 2024. The building's immediate vicinity has experienced recurring issues with graffiti (most recently in January 2023), multiple illegal postings (December 2020), and a collapsed sidewalk (January 2021). There were also two instances of burned-out streetlights on metal poles near the property in 2015 and 2016, both of which were resolved promptly. While the building's internal safety systems were briefly flagged in 2005, it's worth noting that there have been no recorded violations or complaints regarding these systems in nearly two decades since their 2005 correction.

Risk rating

How 930-934 Union 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 1133 buildings in this neighborhood, 600 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.

Number of units

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

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

Estimated permit spend (past 7 years)

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

12-Month severity forecast
No violation 58.0%
Moderate concern 17.6%
Severe concern 24.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
