Initial analysis

The two-unit residential building at 1440-1442 Judah Street in the Central Sunset neighborhood, currently owned by the Lum Family Trust, has a documented history of maintenance and structural issues since its construction in 1947. Most concerning are recent health and safety violations from September 2023, which remain active and include rodent infestation, damaged ceilings, and missing safety equipment related to carbon monoxide and smoke alarms. These violations were documented through a formal complaint that appears to have prompted serious regulatory attention, including first and second Notices of Violation (NOVs) and a Final Warning Letter between September and October 2023.

The building's maintenance history shows various repairs and improvements over the years, including a 2007 reroofing project costing $2,200, window replacements in 1997, and stucco replacement in 1990. A more serious complaint from 1996-1997 reported lack of heat, cold water issues, bathroom usability problems, and ventilation concerns, though these were ultimately resolved by late 1997. Recent 311 calls from 2023-2024 primarily relate to general street cleaning and maintenance issues in the surrounding area, rather than direct building concerns, while specifically mentioning abandoned vehicles, hazardous materials, and graffiti on nearby transit infrastructure. The property appears to have received regular maintenance attention over the decades, but the recent cluster of health and safety violations suggests current significant habitability challenges that require ongoing monitoring.

Risk rating

How 1440-1442 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
