Initial analysis

The two-unit residential building at 221-223 9th Avenue in San Francisco's Inner Richmond district, built in 1940, has undergone several significant improvements over the past decades, with recent maintenance suggesting active property upkeep by the F & E Shimasaki Family Trust. The most pressing recent issues include a May 2023 complaint about heating and electrical problems, though this complaint is currently listed as not active, and there were multiple sewer-related incidents in January 2024 involving a 4-inch vent issue. The building has seen substantial renovations, including a comprehensive 2020 kitchen and bathroom update ($36,000), a major window replacement project in 2018 ($23,000) that installed 21 new windows, and a $21,000 re-roofing project in 2021. The property has also received important infrastructure improvements, such as the electrical upgrade in 2020 that included a new 50-amp subpanel and four circuits, and plumbing updates including new kitchen fixtures and bathroom components.

Historical records show earlier maintenance work including copper plumbing installation in 1993 (permit expired), a 1990 kitchen remodel, and rear window replacements in 2008. The building has experienced some infrastructure-related challenges recently, with multiple service requests in early 2024 regarding sewer issues, though records indicate these were subsequently resolved. The property has also faced external challenges, as evidenced by a public stairway defect regarding a sunken sidewalk noted in November 2023, though this appears to be an external infrastructure issue rather than a building defect. Despite these occasional issues, the frequency of major improvements and repairs suggests regular maintenance of the property, with recent upgrades focusing on both aesthetics and essential systems.

Risk rating

How 221-223 9Th 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.
