Initial analysis

The two-story, six-unit apartment building at 426 22nd Avenue in the Central Richmond neighborhood was built in 1964 and is currently owned by Wilkie H & Nancy K Wong Rev. The property has undergone several significant improvements in recent years, including a completed soft-story retrofit in 2017 (Tier 3) which was properly documented with a CFC issuance, and a $21,000 re-roofing project completed in 2018. A notable maintenance issue emerged in August 2021 involving serious water intrusion problems with rotting siding, which was eventually abated by September 2023. The building has a history of plumbing and electrical concerns, particularly evident from multiple violations and complaints in 2001, when issues with the central alarm system, fire extinguishers, lead-based paint, and various interior surfaces were documented - though all these violations were abated by March 2001.

The property has shown periodic infrastructure updates, including three wall furnace replacements in 2017, and various unit improvements such as Apartment #4's kitchen remodel post-flood damage in 2010 and Apartment #1's extensive renovation in 2007 addressing kitchen and bathroom upgrades. Historical records from 1990 and 2000 show patching of stucco walls and re-roofing work, demonstrating regular maintenance practices. Recent 311 calls (2022-2024) have primarily concerned general cleaning and parking issues around the property. While the building has faced multiple maintenance challenges over the years, records show that most violations and complaints have been addressed through appropriate repairs or improvements.

Risk rating

How 426 22Nd 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.
