Initial analysis

The two-unit residential building at 3621-3623 Judah Street in San Francisco's Outer Sunset neighborhood, owned by Chin Calman, has undergone several significant improvements since its construction in 1945. Recent maintenance issues were addressed in late 2022, when multiple violations were resolved including electrical repairs, plumbing issues, mold remediation, and fire safety compliance - all of which were abated by November 2022. More recent concerns arose in July 2023, with complaints about unpermitted construction work on the back exterior of the building, though these complaints have since been marked as not active. The property has a history of maintenance and improvements including vinyl siding installation in 2011 ($18,482), a bedroom storage and full bath addition in 2002 ($20,000), reroofing in 2006, and various window and stair replacements in previous decades. The building has experienced recurring issues with graffiti and illegal postings on and around the property, with multiple incidents reported between 2018 and 2021, though these were generally resolved promptly through city services. Parking enforcement matters have been documented in 2019, indicating occasional issues with blocking driveways.

Risk rating

How 3621-3623 Judah 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.
