Initial analysis

The property at 1756-1758 Union Street is a two-story, three-unit multi-family residential building located in Cow Hollow, built in 1900 and currently owned by the Tom Fong Irrevocable Trust. The building is undergoing substantial renovations as evidenced by recent permits, including major work initiated in late 2023 ($275,000) to remodel kitchens and bathrooms across multiple units, with follow-up structural revisions in March 2024 involving the removal of a masonry fireplace. Additional improvements include a completed furnace and ductwork replacement in February 2024, and recent electrical upgrades including new smoke detectors and complete rewiring work in December 2023. The building has maintained regular housing inspections, with no significant issues reported in recent years, though there was a minor incident in 2003 regarding improper storage of flammable materials that was promptly resolved.

Historical maintenance records show attention to essential systems, including a complete reroofing in 2010, replacement of the electrical panel in 2021, and various plumbing upgrades. The property has experienced recurring issues with driveway blocking, particularly involving a BMW X5 in 2023-2024, though these are external parking matters. There is currently an open report from April 2023 regarding pavement defects near the property, and two recent parking enforcement actions resulted in citations being issued. The extensive renovation work currently underway, including the addition of new laundry facilities and bathroom fixtures across units, indicates significant investment in improving the building's amenities and systems, though residents should be prepared for ongoing construction activity during this period.

Risk rating

How 1756-1758 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 861 buildings in this neighborhood, 129 are predicted to be safer.
