Initial analysis

The 12-unit multi-family residential building at 478 25th Avenue in the Central Richmond neighborhood, built in 1922 and owned by the Karen M Wong 2000 Trust, has undergone several significant improvements and faced some regulatory challenges over its history. The property has received regular maintenance and upgrades in recent years, including window replacements in 2018 (eight windows at the front), roofing work in 2016, and substantial siding and window updates in 2015 (approximately 1,200 sq.ft. on the left side and rear). The building underwent major vertical and horizontal additions in 1990-1992, which were later the subject of a housing regulation violation in 2001-2002 that cited unauthorized third-floor units with inadequate egress and missing fire safety systems. This violation was eventually resolved through the removal of an illegal third-floor kitchen.

The property has experienced recurring issues with graffiti, with multiple incidents documented between 2009 and 2022, though most have been categorized as "Not Offensive" and successfully resolved through city services. A waterproofing project at the rear corner of the building was permitted in 2009 but appears to have expired without completion. The building's historical records show a consistent pattern of maintenance and compliance efforts, with most recent improvements focused on exterior upgrades and safety systems.

Risk rating

How 478 25Th 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

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 39.8%
Moderate concern 35.1%
Severe concern 25.0%
