Initial analysis

The 4-unit, two-story multi-family residential building at 430 27th Avenue in San Francisco's Central Richmond neighborhood, owned by Kenneth & Voilet J Fong Tr, has a documented history of maintenance and safety issues since its construction in 1964. Recent concerns, particularly from 2023-2024, center around persistent water-related problems, including mold and moisture issues, with the most recent complaint in August 2024 regarding living room leakage and mold concerns. In December 2023, significant problems were reported including water leaks in bathrooms, mold, and unauthorized modifications. The property has experienced recurring maintenance challenges, as evidenced by multiple complaints and violations in recent years, particularly in 2018 when multiple violations were documented including problems with smoke detectors, interior surfaces, water damage, and fire safety equipment, though these were abated by May 2018. The building's history shows various improvement efforts, including a vinyl window replacement project in 2009 and more recently, a permit obtained in 2024 to address unpermitted storage modifications in the garage. The property is also subject to periodic inspections and has had earlier maintenance work completed such as reroofing (1997) and vinyl siding installation (1993). A cooking-related fire incident was recorded, though it was contained and resulted in no civilian injuries.

Risk rating

How 430 27Th 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.
