Initial analysis

The 4233 Judah Street building, a two-story, three-unit multi-family residential structure built in 1991 by Wang Sun Inc in San Francisco's Outer Sunset neighborhood, was constructed with modern safety features including a fire sprinkler system and fireplace installation, as evidenced by permits from 1991. The building has undergone several routine housing inspections over its lifetime, with particular attention required in 2011 when multiple violations were documented regarding rubbish removal, siding weatherproofing, and access to common areas, though these issues were resolved by November 22, 2011. A significant safety concern arose in 1998 when a complaint was filed about a bolted shut backyard fence and door restricting access in case of fire, but this was promptly addressed within a month.

Recent history shows the building has experienced minor maintenance and cleanliness issues, with several 311 calls between 2021-2024 regarding sidewalk cleaning and garbage matters. There was one fire escape complaint in 2017, which was determined to have no merit. While there have been some emergency service calls recorded at the address, none involved civilian injuries or serious incidents, including service calls for water/steam leaks, electrical equipment issues, and medical assistance. The building's permit history shows proper installation of required safety systems at the time of construction, including complete fire sprinkler system installation throughout the building. The property underwent regular inspections in 1998, 2001, 2011, and most recently in 2018, all of which were marked as Not Active, indicating that officials found no ongoing violations at the time of inspection.

Risk rating

How 4233 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.
