AI summary

The three-story multi-family residential building at 806-810 Union Street in Russian Hill, owned by Evelyn Moreno Balistreri, contains four units and was constructed in 1908. The property has undergone several significant safety-related improvements over the past few years, including a comprehensive fire alarm system upgrade in 2020 that involved replacing the fire control unit, pull station, smoke detectors, and motor bells, along with electrical work, and more recently, in December 2021, an exterior sewer and house trap replacement. The building experienced some safety compliance issues in 2005 related to emergency exits and smoke detectors, though these were promptly addressed within three days of reporting.

The building’s maintenance history shows attention to infrastructure improvements, with completed projects including reroofing in 1992 and window replacements in 1984 (though that permit expired). A fire alarm system complaint was resolved in December 2012. Recent records (2024) show multiple reports of street-level issues such as abandoned garbage, debris, and graffiti in the vicinity of the building, as well as some parking enforcement concerns, though these are external to the building itself. Notably, there have been no reported fire incidents in the recent history of the building, though records indicate two fire department responses, one for a building fire (with no civilian injuries or ignition cause details provided) and another for assisting an invalid. The property has been subject to routine housing inspections in 2000, 2005, 2011, and 2013, with all issues recorded during these inspections being promptly resolved.

Risk rating

How 806-810 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
48th percentile

Out of 1133 buildings in this neighborhood, 589 are predicted to be safer.

Moderate concern 24.5%
Severe concern 28.3%
