Initial analysis

This four-story, multi-family residential building at 43-47 Bannan Place in Telegraph Hill was constructed in 1914 and contains three units, currently owned by the Lem Lung Ming Bypass Trust. The building's maintenance history shows some significant safety-related issues that were addressed promptly: between 2004 and 2006, multiple violations were recorded and subsequently resolved concerning the central alarm system, smoke detection, gas meter instructions, and egress obstructions, with all violations marked as "Not Active" by July 2006. A reroofing project was undertaken in 2012, costing $12,950, demonstrating attention to structural maintenance.

Recent history of the property (2018-2024) includes several public works and sanitation-related cases, mainly focusing on street cleaning and sidewalk issues. These incidents primarily involved general cleaning, abandoned waste, and waste removal, with the most recent case being a resolved street defect from November 2024 concerning a collapsed utility cover. Sidewalk condition reports from 2023 indicate there was at least one lifted sidewalk issue that required attention. While these recent cases primarily relate to exterior maintenance and street conditions rather than building-specific issues, they suggest ongoing attention to maintaining the property's immediate environment.

Risk rating

How 43-47 Bannan Pl'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
55th percentile

Out of 684 buildings in this neighborhood, 308 are predicted to be safer.
