Initial analysis

The two-unit residential building at 478 11th Avenue in San Francisco's Inner Richmond neighborhood is a two-story flats and duplex structure owned by the Serrano Claudia Trust, dating back to 1906. The property has experienced several notable incidents over the past decade, with the most recent being a general cleaning complaint about loose garbage in October 2023, though this report was closed due to insufficient information. The most significant pattern observed relates to parking enforcement issues, with three separate incidents documented between 2018 and 2022 involving vehicles blocking driveways or parking on sidewalks, including two identical complaints in December 2022 regarding a white Toyota (license plate 8TSZ595), one of which was resolved through official citation. The building's history also includes a 2012 incident involving offensive graffiti on a pole, which was addressed by the Department of Public Works. While most of these incidents have been properly resolved through appropriate channels, they indicate periodic challenges with street maintenance and parking compliance in the immediate vicinity of the property.

Risk rating

How 478 11Th 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

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.

Building permits, owner's portfolio

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

Estimated permit spend (past 7 years)

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

12-Month severity forecast
No violation 82.6%
Moderate concern 12.9%
Severe concern 4.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
