Initial analysis

The property at 62-64 Williams Ave in the Bayview neighborhood is a two-unit, two-story multi-family residential building constructed in 1911, currently owned by Tim H S & Ella A Wong Revoc. The building has undergone several significant renovations and faced some maintenance challenges over the years. Most recently, in July 2024, a substantial reroofing project was completed at a cost of $24,500. In September 2023, the property was cited for lead paint hazards, with violations issued regarding peeling and flaking exterior paint, though these were officially abated by December 2023. The building has a history of electrical system updates, including a comprehensive electrical renovation in 2006 that involved replacement of wiring and fixtures in multiple rooms and installation of new circuits and panel. Earlier modifications include a conversion of commercial space to residential use in 1995 and fire repairs in the same year that addressed various structural and safety improvements.

The property has experienced periodic issues with parking violations in the surrounding area, particularly during late 2024 and early 2025, with multiple reports of illegal parking and sidewalk obstruction, though most of these incidents were either unable to be validated or resulted in citations. Two unrelated fire complaints were recorded in April 2009, both of which were promptly corrected. The building's maintenance history shows a pattern of addressing significant structural and safety issues, though the recent lead paint violations underscore the importance of ongoing maintenance and safety compliance.

Risk rating

How 62-64 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.

Neighborhood percentile
