Initial analysis

The property at 4100-4106 3rd Street in the Bayview neighborhood is a two-story mixed-use building constructed in 1900, currently owned by We Are Church and containing two residential units. The building has undergone significant modifications and faced multiple compliance issues over the years, with the most recent major developments focusing on its conversion from a restaurant space to a social service facility with outdoor activity area, currently under review. Between 2011-2012, the property experienced substantial code violations including improper plumbing and mechanical systems installation, unauthorized occupancy changes, and electrical safety concerns, though these were ultimately abated through various repairs and system installations. The building has received several important safety upgrades since then, including fire suppression system installations, electrical system improvements, and drainage system improvements in the basement.

Recent activity on the property includes multiple maintenance issues that emerged in 2025, such as a missing sewer vent cover and sidewalk defects, as well as a new business sign installation in 2023. The building's maintenance history shows ongoing attention to safety systems, including fire safety and electrical upgrades, while recent planning records indicate efforts to repurpose the building into a larger social service facility use. The property has experienced recurring issues with garbage and debris on the premises, as documented in multiple 2025 311 calls, suggesting ongoing challenges with waste management in the area.

Risk rating

How 4100-4106 3Rd 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.
