Initial analysis

The 4-unit, 2-story multi-family residential building at 371-373 4th Avenue in San Francisco's Inner Richmond district was built in 1909 and is currently held under the Chin Family Trust 2009. The property has undergone several significant maintenance and safety improvements over the years, with the most recent major work being a completed reroofing project in 2019 costing $23,800. Historical records from 2004-2015 indicate multiple routine safety inspections that revealed various fire safety concerns, including the need for gas shutoff tools, smoke enclosure door closers, smoke detectors, and proper fire extinguisher maintenance. These violations were all addressed and abated, though some required multiple notifications to resolve. The building received a fire complaint in 2018 that was referred to another agency, and there was one carbon monoxide alarm violation noted in 2015 that was subsequently resolved.

Recent activity at the property has primarily involved street-related issues, with numerous parking enforcement calls for vehicles blocking driveways between 2021-2023, and some complaints about waste management including toters being left out (2022) and hazardous materials (glass) on the street (2022). Historical permits show various improvements to the property, including kitchen remodeling and utility upgrades completed in 1984, and earlier permits from the 1980s relating to compliance with Department of Administrative Hearings Investigations (DAHI) requirements. The building's violation and complaint history suggests that while there were significant fire safety concerns in the mid-2000s, the property has generally been maintained in accordance with safety regulations since those issues were addressed.

Risk rating

How 371-373 4Th 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.

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.

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

12-Month severity forecast
No violation 75.8%
Moderate concern 16.9%
Severe concern 7.3%
