Initial analysis

The property at 330-332 25th Avenue in the Central Richmond neighborhood is a three-story, two-unit multi-family residential building constructed in 2005, currently owned by Ken Chan. The construction of this building followed the demolition of an existing two-story single-family dwelling on the site, with initial permits issued in April 2000 for new construction valued at $458,000. The building's construction phase was actively managed, with multiple permits and inspections, including electrical work that involved complete rewiring, installation of a 200-amp service with three meters, and various electrical components needed for the new two-unit condominium.

During the construction period in early 2004, there was a notable incident involving neighboring properties, where excavation work allegedly undermined the foundations of adjacent buildings at 328 and 334 25th Avenue, resulting in an "unsafe building" complaint that was resolved by February 23, 2004. The building's permit history is mostly routine, with several revisions and renewals processed in 2005, including the addition of a half-bath and storage room. More recently, the property has experienced typical urban maintenance issues, with documented incidents including a sewage backup in January 2023 and a fallen tree in March 2019, both of which were resolved. The building's maintenance record appears regular, with no active violations or complaints on file since 2004, suggesting proper upkeep since its construction.

Risk rating

How 330-332 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.

Neighborhood percentile
99th percentile

Out of 2250 buildings in this neighborhood, 22 are predicted to be safer.
