Initial analysis

The Chan Family Trust-owned property at 88 Onondaga Ave is a 2-story, 4-unit multi-family residential building constructed in 1954, currently experiencing several ongoing maintenance issues. The most recent building violations from October 2024 include problems with structural maintenance, egress obstructions, inadequate heating in occupied rooms, and insufficient lighting. There is an active complaint from October 2024 regarding hallway lighting, and the building has a significant history of renovations and repairs. Recent work includes substantial bathroom and kitchen renovations in Units 2 and 4 (August-September 2024), while Unit 3 is scheduled for bathroom tile work in December 2024. The property has undergone multiple routine inspections over the years, with some notable concerns including a serious flooding issue in 1997, and various violations in 2001 related to fire safety, security, and sanitation that were resolved within a month. There was an attempt to legalize an unauthorized dwelling unit in 2018, which was cancelled, and a street space permit was issued in 2014. Recent external issues include multiple reports of garbage and debris on the property, particularly in late 2024, as well as several parking enforcement calls for vehicles blocking driveways and parking on sidewalks.

The building's maintenance history shows a pattern of ongoing improvements and repairs, with attention to both interior (bathrooms, kitchens, floors) and exterior (roof repair in 2010) maintenance. However, the most pressing concerns appear to be the active building violations regarding structural maintenance, egress obstruction, and inadequate heating/lighting systems as of October 2024. The property has undergone various routine housing inspections, with most issues being addressed promptly, though some significant problems have persisted over the years. The Chan Family Trust has actively pursued renovation projects in recent years, as evidenced by the substantial permits issued for bathroom and kitchen improvements across multiple units in 2024.

Risk rating

How 88 Onondaga 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.
