Initial analysis

The Wong Family Trust owns this 2-unit, 3-story multi-family residential building located at 284 23rd Avenue in the Central Richmond neighborhood. Built in 1912, the property has undergone several maintenance and improvement projects, including a recent patio door replacement in March 2024 (cost: $16,796) and a reroofing project in March 2015 (cost: $8,000). The building's recent history shows significant parking-related issues, particularly in late 2024, with multiple illegal parking incidents reported between September and January 2025, resulting in several citations being issued, though some cases were marked as "Unable to Locate" the violator. Between 2021 and 2023, there were four fire-related complaints regarding Shared Spaces operations and two concerning unpermitted operations, though most of these were found to have either no merit, were duplicates, or were deferred.

The property has been maintained according to basic standards, as evidenced by the completed permits for major improvements. While the recent parking enforcement activity suggests ongoing challenges with street parking in the vicinity, this is more related to the neighborhood than the building itself. The fire complaints, primarily focused on Shared Spaces issues in 2021-2023, appear to have been resolved through normal regulatory processes, with most cases being marked as duplicate complaints or having no merit. The most recent building improvements and maintenance work indicate active property management, though prospective tenants should be aware of the historical parking challenges in the area.

Risk rating

How 284 23Rd 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
98th percentile

Out of 2250 buildings in this neighborhood, 45 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.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Building age

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

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 87.6%
Moderate concern 10.1%
Severe concern 2.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
