Initial analysis

The two-unit residential building at 3512 California Street in Presidio Heights, owned by Louie Oh Jung, has experienced several notable incidents over the past five years, with particular attention needed to recent infrastructural concerns. Most alarmingly, in early 2024, there were multiple flooding incidents reported, including fresh water flowing up through the sidewalk, first documented in March and with further complications in April involving possible sewer issues. The property has also faced some maintenance challenges, as evidenced by a June 2024 incident involving construction equipment blocking the sidewalk without proper permits, though this issue was subsequently corrected following an inspection. The building's surroundings have experienced occasional quality-of-life concerns, including a November 2024 case of human waste or urine near the property, and there have been recurring issues with graffiti, with the most recent incident reported in January 2025. While these incidents have generally been resolved through appropriate city channels, the pattern of flooding and infrastructure-related issues in 2024 suggests particular attention should be paid to the building's plumbing and water management systems. The property, a two-story flats and duplex structure built in 1924, has also had several instances of illegal postings (2020-2021) and minor parking-related issues, though these have been less frequent and generally resulted in no action required.

Risk rating

How 3512 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.
