Initial analysis

The two-unit residential building at 510 46th Avenue in the Outer Richmond, owned by Simon S. Chouldjian, is a two-story flats and duplex structure built in 1948. The building's maintenance history includes a completed reroofing project in 2013 costing $9,350, and the removal of a storage room and furnaces from the garage area in 1986. The property has experienced several infrastructure and maintenance issues in recent years, with the most significant being an October 2023 report of overgrown vegetation encroaching on public right-of-way along both Geary Boulevard and 46th Avenue, along with concerns about a fence encroaching on the public right-of-way. This required attention from the Department of Public Works - Bureau of Street Use and Mapping.

The building's recent service requests primarily involve external issues, including graffiti on a mail box (May 2024), while the public service requests between 2022-2024 predominantly relate to abandoned vehicle complaints in the vicinity, with multiple reports in 2022 all resulting in various resolutions, including vehicles being gone upon officer arrival or having complied with laws. There have been other neighborhood maintenance issues requiring city services, such as street cleaning (January 2022) and general service requests. A 2022 outreach and enforcement incident was generated in response to one of the service requests, though the specific nature and resolution of this incident is not detailed in the records. While the building itself appears to be maintained in terms of major systems (evidenced by the 2013 roofing work), the most pressing issues seem to relate to exterior vegetation management and adjacent public right-of-way concerns.

Risk rating

How 510 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.
