Initial analysis

The two-unit residential building at 439 22nd Avenue in the Central Richmond neighborhood is a two-story flats/duplex structure built in 1929, currently owned by the Donun & Lily T Chan Living Trust. The property's permit history shows minimal street-related activity, with two street space permits issued in 2014 and 2010, each with an associated cost of $1.0.

The building's 311 call history from 2013 to 2023 reveals recurring issues in the immediate vicinity, particularly relating to parking violations and street maintenance. In 2023 alone, there were three notable incidents: a report of waste on the street (October), a blocked driveway by a Hyundai vehicle (September), and waste management issues with porta potties on the sidewalk (March). The property has experienced ongoing parking enforcement challenges, with multiple reports of sidewalk parking and driveway blocking between 2018 and 2023, though not all resulted in citation issuance. The area has also faced various street maintenance issues, including reports of loose garbage (2013), a flickering streetlight (2016), and abandoned vehicle complaints in 2016 and 2018, with at least one vehicle being towed in December 2016. While the building itself has generated no internal complaints or violations in the provided data, the surrounding area has experienced persistent sidewalk and street-related challenges, particularly concerning parking violations and waste management.

Risk rating

How 439 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.

Neighborhood percentile

Out of 2250 buildings in this neighborhood, 810 are predicted to be safer.
