Initial analysis

The three-unit multi-family residential building at 438-440 26th Avenue in the Central Richmond district, owned by Mark Soon & Kam Revoc Trust, was constructed in 1987 and features three stories. The building has experienced several significant events over its history, including a fire incident in 1991 that required repairs to redwood siding, and a major renovation in 1985 that added a third story to the structure. In 1999, modifications were made to remove a kitchen and a room at the rear of the garage level.

The building has undergone two routine apartment house inspections by Housing Inspection Services, one in 2007 and another in 2011, during which multiple fire safety violations were documented, including issues with fire extinguisher maintenance and accessibility. The owner addressed these violations, with records showing completion by January 25, 2011. There was also a complaint in 1999 regarding an illegal ground floor apartment, which was resolved by March 16, 2000. Recent activity around the property has primarily involved street maintenance, with several reports of abandoned furniture and loose garbage on the sidewalk between 2020 and 2024, all of which were resolved by city services. There were three parking violation complaints recorded in 2020 regarding vehicles blocking driveways or parking on the sidewalk, though enforcement officers were unable to locate the vehicles in each instance.

Risk rating

How 438-440 26Th 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, 382 are predicted to be safer.
