Initial analysis

The 11-unit, 3-story apartment building at 1178-1188 Union Street in Russian Hill, owned by Tom Henry G G & Gayle B L, was constructed in 1912 and has undergone several significant maintenance and safety improvements over the past decades. Most notably, the building completed mandatory seismic retrofit compliance in 2017 with two permits totaling $88,000, achieving "Work Complete, CFC Issued" status in the Tier 3 soft-story program. The building has experienced recurring maintenance issues, with a particularly significant violation in 2011 regarding fallen stucco and facade problems, which was resolved through $25,000 in repair work. Earlier historical records from 2001 indicated various violations including lead paint concerns, stair repairs needed, and plumbing/electrical issues, all of which were subsequently addressed.

Recent inspection records show a consistent pattern of addressing both routine maintenance and emergency issues. The building has maintained compliance with major safety requirements, including the seismic retrofit program. However, the property has experienced recurring sewer-related issues in early 2024, with three separate sewage backup incidents reported through 311 calls. The building's maintenance history shows periods of significant attention to structural and safety concerns, particularly in the early 2000s and in response to the 2011 stucco violation. Recent 311 calls in 2023-2024 primarily relate to external issues such as garbage, parking, and sewer problems, suggesting ongoing attention to building systems and infrastructure.

Risk rating

How 1178-1188 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.
