Initial analysis

1082 Union Street is a 3-story, 13-unit multi-family residential building located in San Francisco's Russian Hill neighborhood, constructed in 1914 and currently owned by Stephen A. Calegari. The property has experienced several significant maintenance and safety issues over the past decade, with particular concerns regarding fire safety systems. Recent records from 2022 noted deficiencies in the fire escape systems, with complaints filed about structural concerns with both Housing Inspection Services and the Building Inspection Division. In 2017, the building received violations related to sprinkler testing and maintenance, along with multiple fire code violations that were documented. The building's maintenance history shows attention to structural issues, including a 2014 project to install reinforced concrete beams between the existing retaining wall and the building's foundation, as well as repairs to back stairs and cove siding.

Historical violations from 2012 raised concerns about lead-based paint and weatherproofing of the siding, which were addressed through a series of Notices of Violation and compliance actions, with final abatement recorded in January 2016. The property underwent reroofing work in 2004, and there have been several routine housing inspections conducted over the years, with most recent issues being addressed promptly. Recent 311 calls primarily relate to exterior and street-related concerns, including parking issues and sidewalk maintenance, with the most recent incident in August 2023 involving a parking enforcement request. While the building has experienced various maintenance challenges, records indicate that most violations have been addressed through proper channels, though some fire safety system concerns remain notable in recent years.

Risk rating

How 1082 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
