Initial analysis

The three-story multi-family residential building at 609 Judah Street in the Inner Sunset, owned by Edward G Wong & Diana Low T, was constructed in 1984 and contains two units. Historical records show three building permits from the early 1980s, with one significant permit for reroofing completed in 1989, following which the building experienced notable maintenance issues. A serious complaint filed in January 2008 documented ongoing roof leaks causing water damage in two bedrooms, affecting ceilings, walls, carpets, and personal property, with mold presence in one bedroom; this issue reportedly persisted until June 2009.

Most recently, the property has faced numerous parking-related challenges, particularly in August 2024, with multiple reports of vehicles blocking driveways, resulting in several citations. There were also three reports of abandoned vehicles in the area during the same month, though all were resolved with vehicles being gone upon inspection. Additional incidents include an abandoned vehicle case in July 2024 and a sidewalk parking violation that resulted in a citation. In February 2024, there was a successful resolution of an encampment situation near the property, and in October 2024, a tree maintenance issue involving a hanging limb was resolved by the Department of Public Works.

Risk rating

How 609 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 1493 buildings in this neighborhood, 358 are predicted to be safer.
