Initial analysis

The two-unit multi-family residential building at 546-548 17th Avenue in the Central Richmond neighborhood is a 2-story flats and duplex structure built in 1922, currently owned by Yip Clifford C&nancy T Rev. The building has experienced recurring issues with the rear exterior stairs, which have been documented as unsafe on multiple occasions. Most recently, in February 2024, there was a complaint about water intrusion, heating issues, and mold, with reported room temperatures remaining in the 50s despite heating being turned on. A significant stair-related incident occurred in March 2023 when a stair fell through while someone was walking on it, and this marked the fourth such occurrence, with claims that the owner was refusing to replace the staircase. Previous repairs were completed in both 2019 and 2023, including back staircase repairs and handrail installations, though the recurring nature of the stair issues raises ongoing safety concerns.

In addition to the staircase problems, the building has faced regulatory compliance issues, including a 2023 citation requiring an affidavit for smoke and carbon monoxide detectors. The property has had multiple parking-related incidents near the building, with several reports of blocked driveways between 2014 and 2024, though these are typical urban neighborhood issues not specific to the building's condition. Street maintenance matters were reported regarding pavement defects near the property between 2010 and 2017, which were subsequently resolved by city services.

Risk rating

How 546-548 17Th 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.
