Initial analysis

The two-unit, two-story multi-family residential building at 598 Campbell Avenue in Visitacion Valley, currently owned by Yan Shun Lok & Liu Pui Chun, has a documented history dating back to its 1910 construction. The building has undergone some structural improvements over the decades, including foundation reinforcement work in 1986 (cancelled) and 1987, as well as a reroofing project in 1995, though these permits have since expired. The property has experienced multiple fire-related issues between 2016 and 2019, primarily concerning weeds and grass violations, with one incident of intentional fire in 2016 that resulted in no civilian injuries. A significant fire code violation was recorded and abated in 2019.

In recent months (late 2024 to early 2025), the property area has faced numerous municipal service calls, particularly relating to parking violations (sidewalk parking, abandoned vehicles, and illegal parking), with at least three citations issued. There have also been several reports of garbage and debris on or near the property, including incidents involving abandoned furniture and appliances, though most of these cases were resolved by municipal services. A noise complaint was reported in December 2024 and remains open. During the building's ownership history, one notable tenant buyout occurred on April 20, 2021, involving two tenants and totaling $36,069, though this was for a different property address (338 Teddy Avenue) rather than 598 Campbell Avenue.

Risk rating

How 598 Campbell 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.

Neighborhood percentile
57th percentile

Out of 214 buildings in this neighborhood, 92 are predicted to be safer.
