Initial analysis

The three-story, 12-unit apartment building at 745 43rd Avenue in San Francisco's Outer Richmond neighborhood was constructed in 1928 and is currently owned by the Cassens Family Trust. The building has undergone several significant maintenance updates over the years, including a $25,180 complete reroofing project in 2018 and a foundation bolting project in 1990 to meet seismic safety requirements.

The property has experienced recurring fire safety compliance issues, particularly with fire extinguishers and alarm systems. Most recently, in February 2024, a fire extinguisher violation was issued, following a similar violation in July 2020. The building has a history of multiple fire safety violations between 2017 and 2020, including issues with exit maintenance, sprinkler systems, and alarm systems, though most of these have been subsequently corrected or abated. Other historical violations from 2003 involved fire safety features such as fire escape ladders, fire proofing materials, smoke enclosure doors, and self-closing exterior doors, all of which were abated by June 2003. The most recent building-related complaints have been limited to routine housing inspections, with the last known routine violation occurring in 2011.

Risk rating

How 745 43Rd Ave'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

Out of 1040 buildings in this neighborhood, 1019 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 13.1%
Moderate concern 38.9%
Severe concern 48.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
