Initial analysis

The 4-unit, 2-story multi-family residential building at 4308 Judah St in San Francisco's Outer Sunset neighborhood, owned by Shen Family Trust, has undergone significant recent safety improvements following a substantial fire incident in December 2022 that rendered the building temporarily uninhabitable and resulted in comprehensive damage requiring $680,000 in repairs. Since then, the property has seen extensive remedial work, including the installation of a new fire sprinkler system throughout the building (81 heads, $72,259) completed in late 2023, followed by a subsequent fire alarm system upgrade ($16,000) in September 2024 to include fire sprinkler monitoring. The fire damage repairs, completed in May 2023, included comprehensive work across all four apartments, involving the replacement of lights, switches, fans, appliances, and smoke detectors.

The building's historical maintenance record shows attention to structural issues, including recent repairs to the front stucco wall ($30,000) completed in October 2023, and previous minor stucco repairs in 2004. Past violations from 2002, primarily related to fire safety and gas utility requirements, were addressed promptly within two months. While there have been several 311 calls regarding the building's immediate vicinity in recent years (including human waste and flooding issues), these primarily concern street-level services and not building-specific problems. The property's current fire safety systems, now fully upgraded with modern equipment, represent a substantial investment in resident safety and compliance with current codes.

Risk rating

How 4308 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.
