Initial analysis

The three-unit, three-story building at 1715 Union Street in Cow Hollow, currently owned by the Edwin L Mah Revocable Trust, has a mixed-use designation that includes retail space and residential units. Built in 1923, the property has undergone various modifications and improvements throughout its history, with the most significant recent work being a fire suppression system upgrade in 2022 to comply with v.l.300 code, and a house trap replacement in 2021. The building has a history of restaurant-related improvements, including multiple fire suppression system installations and kitchen modifications from the late 1980s through the late 1990s, suggesting that a food service establishment has long been part of the property's commercial component.

The property has experienced some concerning events, particularly regarding safety and maintenance. In 2009, fire violations were recorded for blocked exits and storage in pathways, though these conditions were subsequently corrected. Between November 2024 and January 2025, there were eight consecutive reports of garbage and debris issues, primarily involving overflowing city garbage cans, which may indicate ongoing waste management challenges in the area. The building's fire safety systems have required attention over the years, with documented complaints about alarm systems in 2016 that were resolved within a month. The property's records show regular maintenance and compliance work, including historical permits for reroofing (1991) and various renovations, though some permits from 1997 for accessible improvements expired without completion. The building currently holds an approved Type 41 ABC license, indicating a legally permitted alcohol sales operation in conjunction with its existing restaurant use.

Risk rating

How 1715 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
36th percentile

Out of 861 buildings in this neighborhood, 551 are predicted to be safer.
