Initial analysis

The property at 23-25 Bernard Street is a two-unit, two-story multi-family residential building located in Nob Hill, constructed in 1904 and classified as a Flats & Duplex structure. The only significant building improvement on record is from September 1985, when the installation of 11 aluminum windows in existing frames was completed. The property's maintenance history shows a pattern of street-level issues and community concerns rather than building-specific problems, with no records of building code violations or major maintenance issues directly affecting the structure.

The building's street and sidewalk area has experienced several incidents requiring attention between 2010 and 2020, including a hazardous materials incident involving glass (2020), paper spills (2014), and various cleaning needs such as graffiti removal (2011) and loose garbage (2010). There have been two separate reports of abandoned vehicles near the property (2011 and 2015), though in both cases, the vehicles were gone when authorities arrived. A street lighting issue was reported and resolved in 2012 with the replacement of a flickering lamp and photocell. While these external incidents have been generally minor and promptly addressed, they represent the primary focus of recorded interactions with city services in relation to this address over the past decade, with no documented concerns about the building's structural integrity or internal systems.

Risk rating

How 23-25 Bernard 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
96th percentile

Out of 1125 buildings in this neighborhood, 45 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.

Building age

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

Neighborhood location

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

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

12-Month severity forecast
No violation 79.9%
Moderate concern 9.3%
Severe concern 10.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
