Initial analysis

The property at 422 25th Avenue in San Francisco's Central Richmond district is a two-story, three-unit multi-family residential building constructed in 1984, currently owned by S Lew Family LLC. The building's most significant incident occurred in December 2001 when housing inspection services filed multiple violations including the need for smoke detectors in the lobby and stairs, a gas utility shutoff tool, and the removal of combustible storage or installation of automatic fire sprinklers. These violations were related to uncovered construction work purportedly creating an illegal apartment at the rear of the garage level, which was subsequently resolved by January 2002. The only other notable building permit on record was from 2001 to remove work at the rear of the garage level, and the original demolition permit from April 1984.

More recently, the property has experienced recurring issues with driveway blocking, with at least 11 documented incidents between 2022 and 2024, resulting in several citations being issued. There was also a report of a damaged tree in August 2023, though it was determined to be a young tree that may have been located at a nearby address rather than in front of the subject property. While the fire incident record shows a "900 Special type of incident" entry, no civilian injuries were reported and no specific details are available. The building's record shows relatively few issues in recent years compared to the significant violations of the early 2000s, suggesting improved compliance with safety requirements since the earlier incident.

Risk rating

How 422 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

Out of 2250 buildings in this neighborhood, 225 are predicted to be safer.
