Initial analysis

The two-unit residential building at 807 46th Avenue in San Francisco's Outer Richmond neighborhood is a two-story flats and duplex structure built in 1947, currently owned by John Y C Tang. The property's documented history shows persistent issues with tree maintenance and vegetation, particularly in 2024, with multiple reports of overgrown trees requiring attention. These included concerns about trees near communication lines, though one such report from May 2024 was resolved with information directing residents to online maintenance schedules and outlining service limitations. The property has also experienced recurrent issues with abandoned furniture and debris on public property adjacent to the building, with three separate incidents reported between 2022 and 2024, all of which were resolved through proper channels.

Additional historical context shows the building has had various maintenance and safety matters addressed through city services, including a damaged tree incident in December 2022 that required removal and inspection, and an overgrown tree situation in 2022 that went through the regular resolution process. The property has experienced some minor parking-related issues in early 2022, with reports of a Honda minivan parking violations, though these could not be validated by responding officers. While these incidents reveal some ongoing maintenance and safety considerations in the vicinity of the building, it's worth noting that the majority of these issues have been systematically addressed through appropriate city services and agencies.

Risk rating

How 807 46Th 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.
