Initial analysis

The 7-unit multi-family residential building at 2585 Union Street, Cow Hollow, is a 3-story structure built in 1908 and currently owned by the Hazel R O'Brien Trust. The property has undergone significant renovations and improvements over the past decade, with the most recent being three tree maintenance issues reported in late 2024. Major work completed includes multiple unit renovations (Units 3 and 4 in 2015-2016), structural improvements including underpinning (2015), roof replacement (2014), and garage door replacement (2014). The building has addressed safety concerns through various fire safety upgrades, including smoke chamber sealing and fireplace work in 2014. A tenant buyout occurred in May 2015 for $57,500.

The building achieved compliance with San Francisco's mandatory soft-story retrofit program, completing required work and receiving a CFC. Historical violations from 2000-2004, including issues with smoke detectors, security requirements, and boiler permits, have all been resolved. Recent fire incidents were minor, consisting of three incidents with no injuries noted, two of which were system malfunctions. However, there are currently three open service requests related to parking signs and tree maintenance from 2024, as well as some recurring tree maintenance issues.

Risk rating

How 2585 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
18th percentile

Out of 861 buildings in this neighborhood, 706 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 30.0%
Moderate concern 26.8%
Severe concern 43.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
