Initial analysis

The 9-unit multi-family residential building at 3129-3139 Folsom Street in Bernal Heights, owned by Wells Eryn Rachel, is a three-story structure built in 1909. The property has undergone several significant improvements over the past decade, most notably completing a mandatory soft-story retrofit in 2015 (Tier 3) that included the installation of shearwalls, grade beams, and epoxy anchors for seismic safety. Recent maintenance includes a bathroom remodel in 2022 ($10,000), reroofing in 2019 ($22,000), and various infrastructure upgrades such as furnace replacements and fire safety improvements. Notable historical issues were documented in the early 2000s, including a rodent infestation, mold problems, and various building code violations, though all of these were resolved by 2005. The building received significant electrical system upgrades in 2010-2011, including complete rewiring of all units and installation of smoke detectors. Recent maintenance has focused on individual unit improvements, with multiple bathroom renovations and system upgrades documented between 2012 and 2023. There have been no active housing code violations since 2005, and the building's recent maintenance record suggests ongoing investment in property upkeep. Recent 311 calls related to the property have primarily concerned street cleaning and sidewalk maintenance issues rather than building-specific concerns, with the most recent being a sewage backup incident in June 2024 that was promptly resolved.

Risk rating

How 3129-3139 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.
