Initial analysis

The Healy Family Trust owns this historic 2-unit, 2-story multi-family residential building located on Union Street in the Cow Hollow neighborhood, dating back to 1904. The property has undergone various significant maintenance and improvement projects over the years, with the most recent major work being a comprehensive bathroom renovation on the second floor in 2004 which included new shower installation (cost: $18,000), along with some electrical upgrades. The building has a documented history of proactive maintenance, including two complete reroofing projects (2001 and 1996), siding and window replacement in 1997, and earlier structural improvements such as seismic upgrading of the basement in 1990 and repairs to dryrot-damaged elements in 1986. Cancelled and expired permits from 2000 for a fourth-floor addition and from 1999 for a solar system installation indicate these projects were not pursued to completion.

The building has experienced multiple false fire alarms over the years, including several smoke detector and alarm system activations, though none resulting in civilian injuries or actual fires. Recent concerns have primarily centered around parking issues, with multiple reports between 2018-2023 regarding vehicles blocking driveways or parking on sidewalks, though most of these cases resulted in either citations or the responding officers being unable to locate the offending vehicles. A stop sign repair was completed in 2018 and there was one instance of illegal postings in 2015 that was resolved. The property has maintained its residential classification throughout its history, with no recorded tenant buyouts at either 2821 or 2823 Union Street.

Risk rating

How 2821-2823 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, 241 are predicted to be safer.
