Initial analysis

The 12-unit, 2-story apartment building at 331 Judah Street in the Inner Sunset, owned by Judah LLC, was constructed in 1960 and has undergone several significant improvements over the years. Most notably, the building completed its mandatory soft-story seismic retrofit in 2016 at a cost of $90,000, which included the installation of a moment frame and foundation reinforcements. The property has experienced recurring issues with fire safety and building maintenance, as evidenced by multiple fire code violations and complaints between 2016-2018 regarding extinguishers, exit maintenance, and street numbering. In March 2006, the building faced several violation notices requiring attention to water damage, plumbing issues, fire proofing repairs, and other interior problems, though these were all abated by April 2007. More recent concerns emerged in 2021 regarding security and access control, with complaints about trespassing, inadequate building entry systems, and lack of surveillance equipment. The building's maintenance history shows regular upkeep, including window replacements (2003-2006), roofing work (2001, 2012), and street space permits in 2016 and 2018. Parking-related issues have been frequent in the vicinity, with multiple citations for blocked driveways recorded between 2022-2024, though these are external to the building's management. The property has maintained compliance with soft-story regulations and generally addresses violations when cited, as demonstrated by the abatement of fire violations related to extinguishers and exit signs in 2017.

Risk rating

How 331 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.

Neighborhood percentile
