Initial analysis

The three-unit, three-story multi-family residential building at 49 Bannan Place in Telegraph Hill, owned by Yu Family Trust, was constructed in 1907 and has experienced several significant maintenance issues over the past two decades. Two routine inspections in 2004 and 2006 revealed multiple safety concerns, including problems with stairs, handrails, fire extinguishers, and the central alarm system, all of which were subsequently addressed through building permits totaling approximately $3,800 in repair costs. While these violations were abated by August 2004, more recent complaints between 2017 and 2024 primarily relate to street and sidewalk maintenance issues near the property, including reports of garbage, debris, and illegal parking, which remain external to the building's structural and safety systems.

The building's permit history shows consistent attention to stairway maintenance, with repairs documented in both 2004 and 2006, suggesting a recurring concern with this safety feature. A 1985 permit for door replacement and bathroom painting was cancelled, though another related permit from the same year was successfully completed. Recent 311 calls in 2023-2024 have focused primarily on neighborhood maintenance issues rather than building-specific problems, indicating no major internal building violations have been reported in recent years. The property's historical records suggest that while there have been periodic safety and maintenance challenges, particularly in the mid-2000s, these issues have generally been addressed through proper channels and permits.

Risk rating

How 49 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
57th percentile

Out of 684 buildings in this neighborhood, 294 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

12-Month severity forecast
No violation 72.2%
Moderate concern 20.9%
Severe concern 7.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
