Initial analysis

The two-unit residential building at 30 Bannan Place in Telegraph Hill, owned by Chow Ngan Wen, has shown a notable pattern of parking-related issues during the past year. From March 2023 to November 2024, there have been multiple incidents involving illegal parking, including citations for vehicles parking on sidewalks (most recently in November 2024), and complaints about vehicles blocking driveways and general parking violations, though enforcement officers were unable to locate the offending vehicles in some cases. The property has also experienced several street and sidewalk maintenance concerns, including reports of human or animal waste (June 2023), loose garbage (March 2023), and a residential totter blocking the sidewalk (September 2023). While most of these issues have been resolved through enforcement or outreach, one parking enforcement request from November 2024 remains open. A construction-related noise complaint filed in November 2024 was deemed invalid due to address verification issues, but this incident, like many others, reflects ongoing concerns about property maintenance and neighborhood conditions in the vicinity of this century-old building.

Risk rating

How 30 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
66th percentile

Out of 684 buildings in this neighborhood, 233 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.

Building age

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

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

Estimated permit spend (past 7 years)

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

12-Month severity forecast
No violation 85.5%
Moderate concern 9.2%
Severe concern 5.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
