Initial analysis

The three-unit residential building at 4244 Judah Street in the Outer Sunset, built in 1986 and currently owned by Yuen Bok Kin & York Ngoi, has undergone several significant improvements and faced various challenges since its construction. The most recent improvements include three completed window replacement projects between 2017-2019, totaling approximately $39,186 in upgrades, featuring fiberglass windows with improved energy efficiency. In 2018, the building underwent exterior maintenance including dry rot repair and stucco replacement (completed), while plumbing and electrical work on the same date included reconnection of amenities. The building's history shows prior concerns regarding unauthorized unit conversions in 2000-2003, with multiple complaints about mold, leaks, and illegal unit modifications. These issues were addressed through various permits, including the removal of an illegal kitchen and window replacements. A series of building violations in 2000-2003 related to fire safety and security requirements were all abated by October 2001.

Recent activity at the property has primarily involved exterior maintenance and upgrades, with no significant building violations or complaints recorded in recent years. The most recent permits (2017-2019) focused on window replacements and door upgrades, suggesting the building is maintained to modern standards. There has been recurring activity regarding abandoned furniture and debris on the property in 2024, as evidenced by multiple 311 calls for street cleaning, though these do not directly reflect on the building's condition or management. The property appears to have stabilized since addressing the illegal unit issue in the early 2000s, with no subsequent complaints or violations regarding unauthorized modifications. The building's recent improvements have focused on energy efficiency and exterior maintenance, with no significant safety or habitability concerns reported in the past several years.

Risk rating

How 4244 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.
