Initial analysis

The two-story multi-family residential building at 384 23rd Avenue in the Central Richmond neighborhood, built in 1923, contains 4 units and is currently owned by the Yee Lin Ko Living Trust. The property has undergone several significant safety-related evaluations and improvements in recent years, most notably a sound level verification in sleeping areas and a life safety witness test completed in June 2023, which suggests ongoing attention to resident comfort and safety. The building's maintenance history shows a roof replacement was done in 2009 at a cost of $4,000.

The property experienced a cluster of serious fire safety violations in September 2003, including issues with the central alarm system, combustible storage, egress obstructions, and other fire-related concerns, though all these violations were promptly abated by November 2003. Between 2004 and 2009, there were documented issues with water intrusion and door swelling at the back entrance, which were addressed through various housing inspections. More recent history shows primarily routine service calls, including three parking-related complaints and several general street maintenance requests between 2019 and 2024, though these external issues are not directly related to building conditions or resident safety. The most recent building inspections and permits indicate that the property is currently in compliance with major safety requirements, though the age of the building and its systems suggests ongoing maintenance will be necessary.

Risk rating

How 384 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

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 68.3%
Moderate concern 20.6%
Severe concern 11.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
