Initial analysis

The property at 2647 Judah Street is a two-story, four-unit multi-family residential building with ground floor retail space, located in San Francisco's Central Sunset neighborhood and built in 1973. The building's maintenance history shows attention to critical infrastructure, with a $13,000 reroofing project completed in 2017 and a gas water heater replacement in 2020, though both permits have since expired. A significant cluster of building violations was documented in July 2001 during a routine housing inspection, primarily related to fire safety issues including improper garbage receptacle placement and fire proofing materials, as well as the need to post gas meter instructional diagrams; however, all these violations were abated by September 2001.

In recent years, the property has experienced multiple parking-related issues, particularly during 2020, with several citations issued for sidewalk parking violations involving a Toyota Sienna and a Honda Accord. These were addressed through enforcement actions by parking authorities or police officers. The most recent incident on record was a citation for illegal parking in July 2024. A graffiti incident was reported in 2018, though it was determined that there were no news racks at the address to be affected. The building's record shows no active violations or complaints as of the current date, suggesting compliance with housing codes since the 2001 violations were resolved.

Risk rating

How 2647 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.
