Initial analysis

The two-story multi-family residential building at 463 23rd Avenue in the Central Richmond neighborhood, owned by Nancy K Wong 1994 Revoc Tr, was built in 1972 and contains 4 units. The building has undergone several significant renovations over the past two decades, with the most recent major electrical work completed in 2016 involving the transfer of four federal panels from a closet to a bedroom, along with installation of Murray panels and breakers. Previous improvements include a kitchen remodel in 2010 (though some associated permits expired), window replacement in 2013, and electrical system upgrades completed in December 2013. The building's infrastructure maintenance includes a reroofing project completed in 2006.

Recent activity around the property has primarily involved parking-related issues, with multiple complaints about vehicles blocking driveways and parking on sidewalks occurring between 2023 and 2024, resulting in several citations. There have been some street cleaning concerns regarding garbage and debris in 2024, including reports of abandoned furniture and waste. Two routine housing inspections were conducted in 2002 and 2011, both of which were resolved. The only documented fire-related incident was a false alarm. While the building's maintenance record shows regular upkeep and improvements, with all recent permits reaching completion status, the area around the property has experienced recurring parking challenges as evidenced by numerous 311 calls.

Risk rating

How 463 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
74th percentile

Out of 2250 buildings in this neighborhood, 585 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.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Estimated permit spend (past 7 years)

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

12-Month severity forecast
No violation 73.0%
Moderate concern 13.2%
Severe concern 13.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
