Initial analysis

The two-story multi-family residential building at 355-357 4th Avenue in the Inner Richmond, owned by George K & Masayo Inouye Tr, was constructed in 1924 and contains three units. The building's maintenance history shows regular upkeep, including a complete reroofing project in 1998. Between 2001 and 2016, there were several routine safety inspections conducted by Housing Inspection Services, revealing various building and fire safety concerns that were subsequently addressed, including the repair of wood stairs, installation of fire extinguishers, and carbon monoxide alarm requirements. The most recent routine safety inspection in 2016 resulted in multiple violations related to fire safety equipment and building maintenance, though these were all resolved by June 2016.

The property has experienced significant plumbing issues, particularly in 2018, with multiple reports of sewage backups through the 4-inch vent system between March and May, suggesting potential infrastructure challenges. Other maintenance records include responses to street lighting issues, abandoned vehicles, and a defaced parking sign on the street. While the building has had its share of violations and maintenance issues over the years, the records indicate that problems are generally addressed in a timely manner once identified, with all known violations being marked as not active. The concentration of sewer-related incidents in 2018 and the fire safety violations noted during the 2016 inspection are of particular note when considering the building's maintenance history.

Risk rating

How 355-357 4Th 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.
