AI summary

The three-story multi-family residential building at 2271 Union Street in Cow Hollow, built in 1902, contains 5 units and includes ground-floor retail space. The property has undergone various significant improvements and faced multiple maintenance challenges over the years. Most recently, in early 2024, there were multiple sewer-related incidents documented, with at least three separate sewage backup reports between February and February/March 2024, though these were ultimately resolved through field work. In 2016, the building underwent a routine safety inspection that resulted in several code violations related to stair safety and smoke detectors, though these were abated within a month. Past improvements include a substantial rear storage area excavation and structural upgrade completed in 2012 ($86,000), window replacements in 2006, and various retail space improvements in 2007 for bakery-related commercial use.

The building's history includes several concerning maintenance issues, particularly relating to water problems in 2003 when complaints were made about mold and moisture in both residential areas and the retail space. Fire safety inspections in 2006 resulted in citations for hazardous waste accumulation and standpipe service requirements, though these violations were subsequently closed. Historical planning records indicate efforts to legalize the building's configuration as containing four residential units and one ground-floor commercial space, which were approved. More recent 311 calls from 2024-2025 have primarily concerned exterior issues such as graffiti and sidewalk cleanliness, with some calls still marked as open. While the building has experienced various maintenance challenges over the years, many of the significant structural and safety improvements have been addressed through regular inspections and permitting processes.

Risk rating

How 2271 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.

Out of 861 buildings in this neighborhood, 689 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 age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

12-Month severity forecast
No violation 46.9%
Moderate concern 20.3%
Severe concern 32.8%
