Initial analysis

Located in San Francisco's Russian Hill neighborhood, 822 Union Street is a two-story multi-family residential building (Flats & Duplex) constructed in 1907, currently owned by the Yick Ho Yan Survivor Trust. The property is undergoing extensive renovations, with multiple active and recent permits showing significant improvements to both units (822 and 824). In 2023-2024, major work has included kitchen and bathroom remodels in both units, window replacements (all 15+ windows), electrical upgrades including new panels and rewiring, plumbing improvements including new furnaces, and the conversion of existing spaces into family rooms with additional bathrooms. The building has also seen structural maintenance, with historical permits showing roofing work in 1993 and 2014.

The property has experienced minimal issues of concern, with most 311 calls relating to routine street maintenance and cleaning rather than building-specific problems. One incident of note occurred in January 2024 regarding alleged illegal construction work, though this case appears to have been transferred for further investigation. The extensive scope of current renovations, totaling over $1 million in permitted work, suggests proactive property maintenance and upgrading of building systems and living spaces. The work includes modernizing both units with new kitchens, bathrooms, electrical systems, and climate control equipment, indicative of a comprehensive update to the building's infrastructure and living conditions.

Risk rating

How 822-824 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
96th percentile

Out of 1133 buildings in this neighborhood, 45 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.

Final warnings, owner's portfolio

Final warnings issued across all buildings this owner is registered on.

12-Month severity forecast
No violation 89.9%
Moderate concern 7.7%
Severe concern 2.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
