Initial analysis

The property at 526-528 Visitacion Avenue is a two-unit, two-story multi-family residential building constructed in 1927, currently owned by Adam Herrera. The building has undergone several significant improvements over the years, with the most recent major work being a reroofing project completed in 2021 at a cost of $7,500. In 2004, the property underwent substantial renovations including the installation of 28 vinyl windows, bathroom and kitchen remodels, and electrical system upgrades comprising a 150-amp main panel and two 70-amp sub-panels, all of which were completed successfully.

The building has experienced some concerning issues in recent years, particularly in 2019 when multiple complaints were filed regarding its condition, with concerns noted about it being abandoned/derelict with structural problems. These complaints were addressed and abated by August 2019. There were also two fire code violations issued in August 2020 related to multiple safety concerns, though these were subsequently abated. More recently, there have been several utility-related incidents in 2024 including a sewage backup from the side sewer vent and multiple reports of sidewalk parking violations. The property has a history of compliance issues, as evidenced by violations in 2002 regarding an unpermitted space heater installation, though these were promptly addressed. While the building has required various corrections over the years, most recent permits and repairs suggest ongoing maintenance commitment, with the notable exception of a period of reported abandonment in 2019 that raised significant concerns about the building's condition.

Risk rating

How 526-528 Visitacion 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.
