Initial analysis

The property at 3228-3230 Folsom St in Bernal Heights is a two-unit, two-story residential building owned by James P. Cancilla and constructed in 1924. The building has undergone several significant electrical upgrades in the past, including the removal of a fuse box and installation of new circuits in 2007, as well as wiring work completed in 2006 that included the installation of lights, switches, and receptacles on both the ground and first floors. The only major structural work on record is a reroofing project from 1998, though this permit has since expired.

Of particular concern is the building's recent history with sewer-related issues, which has been a recurring problem over the past several years. Between 2020 and 2022, there were multiple documented sewer incidents, including at least five sewage backups in 2021 alone, all involving 4-inch sewer vents. The most significant work occurred in May 2021, when approximately 20 linear feet of 6-inch V.C.P. lower lateral piping was replaced due to severe root intrusion that was causing intermittent backups. This replacement involved the lower lateral connection from the curb to the 15-inch main sewer line and required substantial fieldwork at depths of approximately 9 feet. The repeated nature of these sewer issues, with multiple customer callbacks and emergency responses, suggests that while some remediation work has been done, the building has experienced persistent challenges with its sewer infrastructure.

Risk rating

How 3228-3230 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.
