Initial analysis

The three-story, five-unit multi-family residential building at 1067-1071 Union Street in Russian Hill, constructed in 1908, has undergone several significant maintenance and safety improvements in recent years. Most notably, the building completed its mandatory soft-story seismic retrofit in 2017 at a cost of $109,000, with some subsequent revisions to relocate steel moment frames. Other maintenance work has included a 2016 reroofing project and sidewalk repairs in 2007.

The building had multiple safety violations in April 2005 following a routine inspection, which were all resolved by June 6, 2005. These violations included issues with emergency exits, combustible storage under wood stairs, safety handrails, wood stair repairs, electrical wiring, gas meter instructions, and smoke detector compliance. Since then, there have been no building violations on record, and the soft-story retrofit has been completed with a Certificate of Final Completion issued. The most recent building-related incidents have primarily involved external issues such as parking and sidewalk access, with several 311 calls regarding blocked sidewalks and driveways in 2024. All of these recent complaints were resolved through normal enforcement channels, indicating no persistent issues with the building itself or its immediate surroundings.

Risk rating

How 1067-1071 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, 793 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.

Building permits, owner's portfolio

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

Building age

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

12-Month severity forecast
No violation 42.5%
Moderate concern 14.4%
Severe concern 43.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
