Initial analysis

The two-story, three-unit multi-family residential building at 2521-2523 Folsom Street in the Inner Mission, owned by Joseph T. Vargo and built in 1900, has undergone several significant maintenance and improvement projects over the years. The property has had two major reroofing projects completed in 2002, costing $6,400 each, and an underground electrical service conversion with three meters installed in 2004. In early 2002, the building experienced violations related to security and stair safety, which were addressed through repairs including installation of deadlatch locks and back stairs repairs, all completed by July 2002. A moisture-related housing complaint from 1995 was resolved, and more recent electrical system concerns were logged in May 2019.

The property has seen several tenant-related events, including a tenant buyout at the 2523 Folsom Street address in October 2020 for $55,000. Recent activity at the location has primarily involved street maintenance issues, with multiple reports of garbage and debris in 2024, though these are typical urban maintenance concerns and not indicative of building conditions. There were also parking enforcement issues documented in late 2023, including citations for blocking a driveway and a bicycle lane. The building's maintenance history shows regular upkeep with prompt attention to violations, and there have been no major building code violations or safety concerns reported in recent years.

Risk rating

How 2521-2523 Folsom 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.

Neighborhood percentile

Out of 2380 buildings in this neighborhood, 785 are predicted to be safer.
