Initial analysis

The two-unit residential building at 770 22nd Avenue in the Central Richmond neighborhood, owned by the Wong 1988 Trust, is a two-story flats/duplex structure built in 1924. The property has undergone several significant improvements over the past 25 years, with the most substantial recent renovations occurring between 2022-2023, including the addition of a bathroom, remodeling of an existing bathroom, kitchen relocation, and various electrical upgrades including a new 60-amp sub panel and exhaust fans, with a reported cost of $110,000. Prior to these improvements, essential infrastructure work was completed, including the replacement of a 4-inch sewer line and house trap in July 2022, and comprehensive plumbing renovations to the kitchen and two bathrooms in January 2023.

The building has a documented history of maintenance, including two reroofing projects (1988 and 2005) and termite repairs (2000), indicating regular upkeep by the ownership. The property has experienced minimal neighborhood issues, with only two documented 311 calls in recent years: one in 2022 regarding sidewalk parking (which was resolved) and another in 2011 concerning an abandoned vehicle (which was towed due to expired registration). The building's permit and maintenance history suggests that major systems and living spaces have received appropriate attention and upgrades over time, with particular focus on modernizing interior spaces and maintaining essential infrastructure.

Risk rating

How 770 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
96th percentile

Out of 2250 buildings in this neighborhood, 90 are predicted to be safer.
