Initial analysis

The property at 426-428 2nd Avenue in San Francisco's Inner Richmond district is a 2-story, multi-family residential building constructed in 1908, containing 3 units and currently owned by Daniel D. Wong. The building has undergone several significant renovations and maintenance work over the past decades, with the most recent major work being a re-roofing project completed in 2021 at a cost of $9,000. Other notable improvements include a bathroom renovation in 2018 (including new ceramic tile, sink, and toilet), and kitchen and interior renovations in 2011 that involved cabinet replacement and sheetrock work. A concerning issue of dry rot on exterior wood stairs was addressed in 2016, though this followed a minor violation notice from 2015 that indicated several safety deficiencies.

The building has had two routine safety inspections (1999 and 2004) and a more serious inspection in 2015 that identified multiple compliance issues including the need for carbon monoxide alarms, fire extinguishers, and repairs to wood stairs. These violations were subsequently addressed and abated in 2016. Historical records show regular maintenance activities including a re-roofing project in 1990, though specific details of earlier permits from 1982 are not available in the current records. The property has been subject to numerous 311 calls in recent years, primarily concerning abandoned vehicle reports (nine instances between 2023 and 2024), and some general cleaning requests for the street and sidewalk area. These recent external issues appear to be more about neighborhood parking conditions than building-specific problems, and none of the 311 calls directly relate to building safety or maintenance.

Risk rating

How 426-428 2Nd 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.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Estimated permit spend (past 7 years)

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

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

12-Month severity forecast
No violation 78.8%
Moderate concern 16.0%
Severe concern 5.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
