Initial analysis

1125 Union Street is a 3-story, 6-unit multi-family residential building constructed in 1922 in the Russian Hill neighborhood, currently owned by Fred & Laurel Paris Suess 2. The property underwent significant improvements in 2018-2019, including the addition of two new units (Unit #7 and Unit #8) and comprehensive safety upgrades. Major renovations included the installation of a new fire sprinkler system throughout the first floor, an upgraded fire alarm system with new addressable smoke detectors and low frequency sounders, and electrical system improvements with upgrades from 100-amp to 200-amp and then to 400-amp service. The building completed its mandatory Soft Story retrofit work and received a Certificate of Final Completion (CFC) status, demonstrating compliance with seismic safety requirements.

Recent maintenance and infrastructure improvements include plumbing updates such as water heater replacements in 2015, new underground utility installations in 2018, and various street space permits in 2017-2019. The property has experienced several maintenance issues over the years, including a 2004 complaint regarding peeling paint, a 2008 routine inspection with various violations (now resolved), and a 2018 plumbing complaint regarding work without proper permits and hot water issues, which were quickly addressed. Fire safety systems have been actively maintained, with documented fire alarm system complaints in 2012 and 2017 that were promptly corrected. The building's fire incident history shows only non-injurious events related to alarm system activations and gas leaks, with no confirmed fire incidents. Recent 311 calls (2023-2024) primarily relate to street maintenance and garbage concerns, which have been resolved through proper channels.

Risk rating

How 1125 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
27th percentile

Out of 1133 buildings in this neighborhood, 827 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

12-Month severity forecast
No violation 29.7%
Moderate concern 29.5%
Severe concern 40.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
