Initial analysis

The 3-unit residential building at 160-162 23rd Avenue, owned by the Quan Family Trust, is a 2-story flats and duplex structure built in 1922. The building has undergone several significant renovations in recent years, with the most recent work including an interior remodel at unit 162 in December 2021 featuring wall removal and kitchen remodeling, and bathroom renovations in September 2021 including updates to electrical wiring, insulation, and lighting. A gas fireplace was installed in September 2022, and substantial electrical work was completed in 2007 including installation of 50 lights, 40 switches, and 60 receptacles, along with window replacements and bathroom remodels. The building had some serious maintenance issues in 2005, with multiple violations including inadequate heat, unsafe windows, electrical work without permits, and various building repair needs, though these were all abated by May 2006.

More recent history shows ongoing maintenance and improvements, with multiple plumbing and electrical permits issued between 2007 and 2022 covering bathroom, kitchen, and laundry facilities. The property has experienced recurring parking-related issues in the surrounding area, with multiple complaints about blocking driveways and sidewalk parking between 2022 and 2024, though these are not directly related to the building's condition. The most recent building-related activity was a parking enforcement call in December 2024. The building's maintenance record shows regular upkeep and improvements over time, with no active violations or complaints on file as of the latest data.

Risk rating

How 160-162 23Rd 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.
