Initial analysis

The 4-unit multi-family residential building at 462 20th Avenue in the Central Richmond neighborhood is a 2-story structure built in 1971, currently owned by Richmond & Sunset Inc. The building's most recent significant maintenance work was completed in 2016 with a reroofing project costing $9,500. Of particular note is a cluster of fire safety violations documented in January 2003, which were all addressed and abated by February 25, 2003. These violations included issues with combustible storage, missing fire extinguishers, smoke detectors, and door closers. The building underwent a routine housing inspection in 2010 that was resolved without any reported violations. More recent history shows some resident/visitor parking issues between 2019-2020, with multiple complaints about driveway blocking, and one sewer-related incident in 2013 involving a 4-inch sewer vent backup that was promptly addressed and resolved by PUC Sewer Operations. While the building has had various issues in its past, it appears that all documented violations have been resolved, with no active violations currently on record.

Risk rating

How 462 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.

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 75.4%
Moderate concern 14.1%
Severe concern 10.5%
