Initial analysis

The Cow Hollow multi-family residential building at 2338-2340 Union Street is a 2-story, 9-unit apartment structure built in 1919, currently owned by Kathleen & Teresa Kelley 20. The property has undergone significant safety and infrastructure upgrades in recent years, most notably the installation of a comprehensive fire sprinkler system ($12,000) and a new fire alarm system ($23,000) in 2019 to bring the building into compliance with current fire safety requirements. The building completed a substantial electrical upgrade in 2020, including the installation of a new 400-amp service adding 4 new meters, and underwent soft-story seismic retrofit work which is now complete and CFC-issued. In 2023, the building received violation notices for the alarm system and sprinkler service maintenance, though these have since been abated.

The property has a history of regular maintenance and improvements, including plumbing work in 2019 for sewer systems and water pipes in multiple units, as well as various unit renovations. Historical records show some building code violations from 1997-2008 regarding fire safety and door safety issues, though these were resolved. Recent 311 calls primarily relate to street and sidewalk matters outside the building, including a sidewalk defect (2024) and garbage issues (2024). The building's current systems appear to be properly maintained, with most recent permits and violations being addressed in a timely manner. The addition of three accessory dwelling units on the first floor was completed as part of a 2017 soft-story retrofit project.

Risk rating

How 2338-2340 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

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.

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

12-Month severity forecast
No violation 42.5%
Moderate concern 40.3%
Severe concern 17.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
