Initial analysis

The 920 Bay Street property is a three-story, 9-unit multi-family residential building located in Russian Hill, constructed in 1925 and currently owned by Jean E. Caramatti. The building has undergone several significant improvements in recent years, most notably completing a mandatory soft-story retrofit in 2015 (costing $50,000), which brought the building into compliance with San Francisco's seismic safety requirements. The building has experienced recurring maintenance issues, particularly with its plumbing systems, as evidenced by multiple complaints and repairs including a 2016 incident involving corroded DWV pipes and a malfunctioning water closet in the garage ($1,000 repair cost). The property has had three documented fire safety system violations between 2015-2022, including issues with fire extinguishers and alarm systems, though records indicate these conditions were promptly corrected.

Historical maintenance records show attention to basic infrastructure needs, with multiple roofing projects documented (1995, 2003, 2008) and window replacements completed in 2003 ($8,700). The building has experienced various routine maintenance issues over the years, including concerns about lead paint (2013), window weatherproofing (2013), and security features such as fire escape ladders and fire extinguisher upkeep (2006). Recent fire safety inspections in 2020-2022 have identified and resolved issues with alarm systems and fire extinguishers. The property has generated multiple 311 calls regarding parking violations in recent years (2021-2025), though these are external issues not directly related to building condition. While the building has had its share of maintenance challenges, records indicate that most violations and complaints have been addressed through proper channels, with many being resolved within reasonable timeframes.

Risk rating

How 920 Bay 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
4th percentile

Out of 1133 buildings in this neighborhood, 1088 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 8.1%
Moderate concern 23.7%
Severe concern 68.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
