Initial analysis

The two-story, four-unit apartment building at 3631 Judah Street in San Francisco's Outer Sunset neighborhood was built in 1954 and is currently owned by Damon Rivera. The building's maintenance history shows several significant roofing projects, with the most recent completed in 2016 at a cost of $7,880. The property experienced a notable cluster of violations in 2001 requiring multiple safety and maintenance upgrades, including ensuring fire escape access, updating fire extinguishers, addressing lead paint hazards, installing proper door viewers, repairing stair handrails to apartment #4, and providing correct apartment identification numbers. These violations were all abated by November 2001. An earlier repair record from 1990 documents structural work addressing dry rot damage. The most recent building permit records are limited to the 2016 roofing project, with no major violations or complaints recorded in the past 15+ years.

Recent 311 calls associated with the address (from 2021 to 2024) primarily concern external issues such as parking violations, abandoned vehicles, and street cleaning matters, rather than building-specific concerns. These calls indicate ongoing challenges with parking management in the area, including multiple reports of vehicles blocking driveways and parking on sidewalks, though most of these complaints were either not validated or resolved by responding officers. There were also some issues with illegal postings and a defaced parking sign in 2021, which were addressed by city services. However, none of these external issues appear to directly impact the building's condition or safety systems.

Risk rating

How 3631 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

Out of 632 buildings in this neighborhood, 404 are predicted to be safer.
