Initial analysis

The Yu Family Trust property at 355 28th Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Central Richmond district. Built in 1923, this flats/duplex structure has undergone minimal documented maintenance over the past several decades, with only two significant permitted works on record: a street space permit issued in 2016, and a reroofing project from 1997, though the latter's status is listed as expired. The building's documented history shows several infrastructure and maintenance challenges, particularly between 2012 and 2015, including multiple reports of pavement defects (with records showing similar issues in May, December 2012, and February 2013) and cleanup needs (noted in June 2012). A sewage backup incident was reported and resolved in August 2015, occurring simultaneously with another sanitation issue involving waste on the street, which was also addressed. More recently, in December 2019, there were two parking-related incidents near the property involving construction equipment and a Gradwell Truck blocking access, though both cases were either unresolved or resulted in no officer presence. While the property's documented history shows some maintenance issues from external sources (primarily street conditions), there are no recorded safety violations or building code concerns specifically related to the structure itself, and the relatively minimal number of permits and complaints over the past few decades suggests either limited required maintenance needs or potentially incomplete record-keeping.

Risk rating

How 355 28Th 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
73th percentile

Out of 2250 buildings in this neighborhood, 608 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.

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.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

12-Month severity forecast
No violation 87.6%
Moderate concern 9.8%
Severe concern 2.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
