Initial analysis

The three-unit residential building at 1035-1039 Union Street in Russian Hill, owned by the John & Barbara North Trust, is a three-story flats and duplex structure built in 1913. The property has undergone several significant improvements in recent years, with the most recent major work being the replacement of four rear-facing windows in October 2023 and a comprehensive kitchen remodel at unit 1039 completed in June 2023 that included new appliances, flooring, electrical upgrades, and safety features such as smoke and carbon monoxide detectors. Prior improvements include the 2014 kitchen and bathroom remodel at unit 1037, and in 2016, gas line rerouting work was completed for units 1035, 1037, and 1039.

The building has maintained good safety and maintenance records, with only routine inspections recorded in 1999 and 2005 showing no significant issues. Recent months have seen multiple reports of driveway blocking incidents near the property, with at least several resulting in citations being issued between September and December 2024. While there were two minor fire department responses to the building (one for a false alarm and another for smoke removal), neither incident posed any danger to residents. The property has regularly undergone updates to maintain modern standards, including previous work in 2010 to install washer and dryer connections in a laundry room, demonstrating ongoing maintenance and infrastructure upgrades by the current ownership.

Risk rating

How 1035-1039 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
