Initial analysis

This three-unit, three-story multi-family residential building located at 2933-2937 Folsom Street in the Inner Mission was built in 1910 and is currently owned by Steve & Margo C Drosos (2015). The property experienced significant maintenance issues in 2017-2018, leading to multiple building violations including problems with windows, drainage pipes, weatherproofing, floor coverings, water damage, bathroom fixtures, and more, all of which were addressed through various permits and completed by December 2019. In 2018, substantial improvements were made including window replacements (28 windows total), bathroom remodels, and plumbing repairs, along with a reroofing project costing $15,000 which was completed in September 2018. Historical records show a previous complaint from 2013 regarding poor building condition and falling windows, and two earlier reroofing projects were completed in 1987 and 1997. The building has had several maintenance issues requiring attention, including a damaged side sewer vent cover in 2015 and various street cleaning matters. Recent concerns from 2023 involve tree roots lifting the sidewalk near the property, and there were two bicycle lane blocking incidents reported in 2021-2022, though these are not directly related to the building's condition. The most recent permitted work on the building was the 2018 window replacement project, which was conducted to address various housing code compliance issues.

Risk rating

How 2933-2937 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, 976 are predicted to be safer.
