Initial analysis

The property at 956-960 Union Street is a two-story, four-unit multi-family residential building located in Russian Hill, constructed in 1932 and currently owned by Rainer Albert & Gisela Ceci. The building underwent significant modifications in the mid-2000s, including the controversial conversion of basement storage space into a dwelling unit in 2006 (non-completed permit) and the installation of fire sprinklers throughout the basement area in 2008, though these improvements were ultimately addressed through subsequent permits. Major electrical upgrades were completed in 2012, including the installation of new 200-amp service with multiple meter sockets and circuit breaker panels. The building has experienced a few concerning issues over its history, including a roof leak complaint from 2000, fire damage repairs in 1995, and most recently, retaining wall modifications that prompted a November 2024 violation, which was abated by December 2024. Multiple improvement projects have been carried out since 2008, including plumbing renovations (two bathrooms, one kitchen), furnace replacement, fireplace installations, and electrical system upgrades. The property has maintained compliance with various safety inspections, though a 2005 routine safety inspection identified several fire safety and security concerns that were subsequently addressed. While recent 311 calls indicate typical urban maintenance issues (such as illegal postings and street cleaning concerns), the building's major systems have received regular updates and maintenance, with most historical complaints and violations being resolved through appropriate permits and inspections.

Risk rating

How 956-960 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 1133 buildings in this neighborhood, 521 are predicted to be safer.
