Initial analysis

The three-story multi-family residential building at 6509 California Street in the Central Richmond neighborhood, owned by Michael L & Janice L Wong L, consists of two units and was constructed in 1989 following the demolition of a single-family dwelling in 1987. The building's maintenance record shows regular upkeep, with significant work including a bathroom remodel on the 2nd floor in 2014 (costing $10,000), repairs to address dry rot in the rear stairs in 2012 ($12,000), and a complete reroofing project in 2001 ($9,950). A minor street space permit was issued in 2017. The property has experienced minimal serious incidents, though there was a fuel burner/boiler malfunction recorded as a fire incident, which was contained with no civilian injuries reported.

The area around the building has seen regular municipal activity, particularly in 2023-2024, with multiple reports of abandoned furniture and general cleaning needs being addressed by city services. Recent concerns have primarily been related to street maintenance, including loose garbage issues in May and October 2023, and occasional parking enforcement matters. A tree inspection in January 2023 determined the tree was in fair condition with no hazardous concerns. There have been two tenant buyouts recorded at the neighboring address of 6517 California Street, though no dates or details are provided in the records.

Risk rating

How 6509 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.
