Initial analysis

The 4-unit, 2-story multi-family residential building at 263 23rd Avenue in the Central Richmond neighborhood, owned by the Angela Wong Trust, was constructed in 1972. The building has undergone minimal permitted improvements over the years, with records showing only two significant work items: a reroofing project from 1995 and a plumbing upgrade in 2008 that included kitchen P-trap modifications and the installation of thermostatic bathtub shower valves to meet current plumbing codes.

The property experienced a series of notable compliance issues in the early to mid-2000s, all of which have since been resolved. A routine housing inspection in 2002-2003 revealed multiple violations including problems with the central alarm system, smoke enclosure door repairs, and fire safety concerns such as combustible storage issues. Another series of violations was documented during a 2005 routine inspection, primarily related to fire safety compliance, including concerns about the alarm panel, garbage receptacle placement, fire proofing materials, and required directional signs. All these violations were officially abated between March 2007 and June 2005. More recently, there have been several street-related service calls in the surrounding area between 2018 and 2025, including reports of garbage, debris, and pavement defects, though these are not directly related to the building's condition or management. The most recent service calls from 2024-2025 are currently open or were recently resolved.

Risk rating

How 263 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
71th percentile

Out of 2250 buildings in this neighborhood, 652 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 77.2%
Moderate concern 12.7%
Severe concern 10.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
