Initial analysis

The two-unit apartment building at 46 Williams Avenue in Bayview, owned by Zhu Austin, was constructed in 1962 and has undergone several notable renovations and faced multiple safety concerns over recent years. Between 2019 and 2020, significant exterior improvements were made, including the installation of a new rear staircase for the second-floor unit, changes to windows and doors, and siding modifications - with permits showing costs totaling $23,000 for these improvements. During 2018, mechanical updates included a gas line connection and 40-gallon water heater change-out, though these permits have since expired.

The property has experienced recurring fire safety concerns, with multiple violations documented in 2019 and 2020 related to sprinklers, fire extinguishers, and electrical hazards - all of which were officially abated. More recently, the building's surroundings have been the subject of numerous municipal service calls, primarily relating to parking violations, with five incidents recorded between May and September 2023, resulting in at least two citations. Additional recent issues include multiple reports of street cleaning violations and debris in 2024, though these are primarily pertaining to public areas rather than the property itself. The building's documented history reveals a pattern of property maintenance and safety compliance efforts, particularly regarding fire safety systems, though some permits have expired without record of completion.

Risk rating

How 46 Williams 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.
