Initial analysis

The two-story, four-unit multi-family residential building at 261 20th Avenue in the Central Richmond neighborhood, owned by Sheh Michael & Qiu Weicong, has a documented history spanning over three decades from 1992 to 2024. The building, constructed in 1970, has undergone several significant maintenance projects, including a complete reroofing in 1992 and waterproof membrane replacement in 1995. Two routine apartment inspections were conducted in 2002 and 2009, during which multiple fire safety violations were identified. These included the need for smoke detectors in the lobby, fire sprinkler installation over garbage receptacles, fire extinguisher maintenance, and exit door repairs. All these violations were officially abated by November 2002.

Recent issues primarily involve parking concerns, with numerous complaints about blocked driveways between 2022 and 2024, resulting in several citations being issued. The most recent service request involved garbage and debris on the property in October 2024, which was resolved by Recology. While the building's major structural and safety systems appear to have been maintained, as evidenced by the completion of historical permits and the abatement of fire safety violations, the property has experienced recurring issues with abandoned vehicles and parking enforcement matters in the immediate vicinity. The building's most recent documented maintenance activity was a street space and sidewalk permit issued in 2009, with no subsequent building permits recorded, raising potential questions about current maintenance practices.

Risk rating

How 261 20Th 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 2250 buildings in this neighborhood, 810 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.

Estimated permit spend (past 7 years)

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

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

12-Month severity forecast
No violation 74.0%
Moderate concern 15.0%
Severe concern 11.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
