Initial analysis

This two-unit residential building, located at 1224 4th Avenue in San Francisco's Inner Sunset neighborhood, is a 1907 two-story flats and duplex structure currently owned by Henry & Julia Yim 2004 Family Trust. The property's permit history reveals two significant renovations: in 1988, improvements were made to the rear of the building including the replacement of existing rooms and stairs, along with the addition of a new laundry room, a project that was successfully completed. More recently, in May 2023, comprehensive gas line replacements were carried out for both units (1224 and 1226), with this plumbing work also being marked as completed. While the building's records show proper maintenance and upgrades over the years, particularly with respect to essential systems like gas lines, the 35-year gap between these major renovations may indicate limited recent structural modifications, though the plumbing work suggests attention to safety infrastructure when required.

Risk rating

How 1224-1226 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.

Neighborhood percentile

Out of 1493 buildings in this neighborhood, 508 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.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

Building permits, owner's portfolio

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

12-Month severity forecast
No violation 82.4%
Moderate concern 11.2%
Severe concern 6.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
