Initial analysis

1150 Union Street is a 9-story, 51-unit multi-family residential building constructed in 1930 in the Russian Hill neighborhood, currently owned by V & L Union Lp. The property has undergone various significant improvements over recent years, with particular attention to fire safety systems. Most notably, from 2019 to 2024, the building has seen substantial fire safety system upgrades including the replacement of the fire alarm panel, installation of new smoke detectors and pull stations, replacement of the fire pump and sprinkler system components, and implementation of evacuation maps. Despite these improvements, the building has experienced recurring fire safety violations, with the most recent violations in 2024 related to the sprinkler/standpipe systems and sleeping area requirements.

The building's maintenance history shows regular upkeep, including a 2018 boiler replacement and a 2017 kitchen and bathroom remodel in unit #706. However, there have been several concerning incidents and complaints. In 2019, there was a power outage affecting half the building, including elevators and stairwell lighting, which residents indicated was not an isolated incident. More recently, in 2023-2024, the building experienced water damage issues (complaint filed July 2023) and underwent multiple repairs related to building systems and safety requirements. The property has a documented history of elevator problems, with multiple incidents of trapped passengers recorded as false alarm responses by the fire department, and has received attention from housing inspection services for various code compliance matters, including a 2019 investigation into carbon monoxide and smoke detector compliance.

Risk rating

How 1150 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
2th percentile

Out of 1133 buildings in this neighborhood, 1110 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 8.2%
Moderate concern 55.7%
Severe concern 36.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
