Initial analysis

4646 California Street is a two-story, three-unit multi-family residential building constructed in 1978, currently owned by the Anne Tang Revocable Living Trust. The property has undergone several significant maintenance and compliance updates over the years, with the most recent being a completed reconstruction of the exterior wooden deck in 2024 at a cost of $10,000, following a complaint about unpermitted deck removal in May 2024. The building's roof has been regularly maintained, with reroofing projects completed in 1989 ($7,000), 2003 ($7,000), and 2015 ($9,500).

A notable cluster of building violations occurred in February 2001, when multiple safety issues were identified, including the need for smoke detectors in the lobby, a gas utility shutoff tool, and fire safety improvements regarding combustible storage. Fortunately, all these violations were addressed and abated by April 2001. The property has experienced various external issues typical of the urban environment, including graffiti on mailboxes (notably in 2021 and 2022), and reports of waste on the street/sidewalk (in 2020 and 2021), all of which were resolved. Recent infrastructure concerns in the vicinity include two pavement defect reports from 2016 and a more recent complaint in October 2024, although these are street-related issues not directly affecting the building itself. The building's maintenance history shows regular attention to major systems like roofing and decks, with prompt response to both routine inspections and violations.

Risk rating

How 4646 California St'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.
