Initial analysis

The three-story, two-unit multi-family residential building located at 523 Campbell Avenue in Visitacion Valley has undergone several significant infrastructure improvements since its construction in 1904. Recent improvements include the installation of solar panels in 2016 (18 PV modules), a new electrical meter main panel in 2012, and major plumbing upgrades in 2014 including the replacement of the house trap and underground main sewer line. The building has also seen earlier maintenance work, including reroofing in 2012 and window replacements in 1998-1999. However, the property has a troubling history of safety concerns, particularly highlighted by multiple complaints filed in October 2018, alleging serious issues including unpermitted structural modifications, gas leaks, illegal plumbing work, and unauthorized electrical installations - some of which reportedly nearly caused a fire. A comprehensive complaint filed in August 2018 detailed hazardous living conditions, including gas leaks, electrical problems, and structural concerns. The building's maintenance history shows both proper upgrades and concerning pattern of complaints regarding unauthorized modifications.

Most recently, between October and December 2024, there have been multiple reports (nine in total) of garbage and debris issues in the vicinity of the property, primarily involving loose waste and abandoned items, though these are not directly related to building conditions. While many of these recent cases have been resolved, they do indicate ongoing challenges with waste management in the immediate area. The building's documented permit history shows regular maintenance and improvements over the years, though the frequency of improvements and repairs suggests ongoing attention to basic infrastructure needs. The property is currently owned by Anne Seeman, though historical records show previous ownership by Seeman Anne.

Risk rating

How 523 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.
