Initial analysis

The property at 1906-1908 Folsom Street is a 3-story, 6-unit multi-family residential building constructed in 1907, currently owned by Robert A. Imhoff. The building has experienced significant maintenance and safety issues over its history, most notably in recent years. As of October 2023, the building is classified as Non-Compliant under the Soft Story program (Tier 4), with an active violation regarding the soft story retrofit that was initially permitted in 2018 for $50,000 but shows no recorded completion. The building has been vacant multiple times between 2018 and 2024, with the most recent vacant building complaint filed in July 2024. Serious safety concerns were documented in 2016 when unauthorized occupants and fire hazards were reported, and the building has consistently attracted issues with encampments, debris, and graffiti, with multiple 311 calls logged in 2024 regarding these problems.

The building's violation history is notable, with a cluster of building and interior surface violations documented in 2000 that included damaged walls, ceilings, and various maintenance issues. While these violations were officially abated in 2002, they suggest a history of maintenance challenges. More recent permits show attempted compliance with safety requirements, including a 2023 permit related to work under a previously approved soft story retrofit, though this work appears to remain incomplete. The building's deterioration over time is evidenced not only by the need for seismic retrofitting but also by historical records showing roof replacement in 1991 and repairs to rotted members in rear stairs and landings in 1990. The property has consistently required attention to address health and safety concerns, with health inspections noted in 2009 and 2010, and current open 311 calls for property maintenance issues, including graffiti and debris removal, suggesting ongoing challenges with building upkeep and neighborhood impact.

Risk rating

How 1906-1908 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.
