Initial analysis

The two-unit residential building at 3924 Folsom Street in Bernal Heights, owned by Irma Malton, is a two-story, multi-family dwelling constructed in 1908. The building's maintenance history shows several significant repairs performed in the early 1990s, including multiple instances of dry rot remediation affecting various areas such as the garage, rear foundation, exterior staircase, and the bathroom and bedroom renovations in 1990. In 1989, aluminum windows were installed in several rooms, and the roof was replaced in 2004 at a cost of $10,100.

The most pressing recent concerns for this property center around persistent parking-related issues, particularly between 2023 and 2024, with multiple reports of illegal parking, driveway blockages, and sidewalk parking. A notable cluster of incidents occurred between April and August 2024, with at least one citation issued for a blocked driveway in April 2024, though many other complaints resulted in officers being unable to locate the offending vehicles. There was also a street cleaning complaint in May 2023 regarding loose garbage, though this was determined to be a private property issue that the city could not address. While the parking issues are primarily external to the building itself, their frequency suggests ongoing challenges in the immediate vicinity of the property.

Risk rating

How 3924 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.
