Initial analysis

The 4-unit, 4-story multi-family residential building at 432-434 Broadway in Telegraph Hill, owned by Wong Dennis T & Annie Tang, has a long history dating back to 1907 with significant maintenance and safety concerns. Most recently, there was an electrical outlet fire incident in July 2023 that was resolved by August 2023, and the building underwent a federal pacific panel replacement in July 2023. The property has experienced recurring fire safety issues, with violations related to extinguishers, fire escapes, and alarm systems documented between 2019 and 2024. During 2017, the building faced several maintenance challenges including heating system failures, electrical issues, and plumbing concerns, which required multiple repairs totaling over $8,000. The building had significant safety violations issued in June 2010 regarding fire escape ladders, emergency lighting, and egress obstructions, though these were marked as abated by July 2015.

The property has undergone various improvements and repairs over the years, including the installation of new faucets, electrical systems, and fire suppression equipment. Earlier records from 2005-2011 show issues with garbage management, roof debris, and sanitation concerns. Recent 311 calls from 2023-2024 indicate ongoing challenges with building surroundings, including reports of graffiti, waste, and blocked sidewalks. While many past violations have been abated, the building's history shows a pattern of recurring fire safety and maintenance issues requiring continual attention, particularly during the 2010s through the present.

Risk rating

How 432-434 Broadway'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.
