Initial analysis

The two-unit residential building at 1568 Thomas Avenue in Bayview, owned by Wendy Waiwah Voong, is a two-story flats and duplex structure built in 1907. The property's maintenance record shows several significant events, with the most recent being a sewage backup issue in September 2023 that was promptly resolved by PUC Sewer Operations. During 2017, the building experienced plumbing issues requiring repairs to multiple sinks and toilets, though these violations were abated within two weeks. A gas houseline extension was completed in 2010, servicing both 1568 and 1570 Thomas Avenue. Historical maintenance includes a reroofing project from 1996, though this permit has since expired.

Recent activity around the property has centered primarily on public infrastructure and sanitation concerns. Between July 2024 and October 2024, there were multiple reports of garbage and debris issues near the property, with at least one instance involving a refrigerator appliance removal in August 2024. A pavement defect was reported and resolved in January 2024. Notably, there was a tenant buyout at the adjacent address (1556 Thomas Avenue) in October 2017, involving a payment of $33,031 to five tenants. While the building has experienced some maintenance issues in the past, records indicate that these have typically been addressed in a timely manner once reported.

Risk rating

How 1568 Thomas 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.
