Initial analysis

The three-unit multi-family residential building at 426-430 Greenwich Street, located in San Francisco's Telegraph Hill neighborhood, was constructed in 1916 and is currently owned by the Nambiar Werth Family Trust. The property underwent significant safety and modernization improvements in the early 2000s, including the installation of a comprehensive NFPA 13 fire sprinkler system with dry standpipe ($16,000) and a complete electrical system upgrade featuring 400-amp service, new wiring, and multiple circuit installations ($500,000). Additional improvements included the installation of a 3-stop residential hydraulic elevator and fire alarm system, both completed in 2004.

In July 2006, a routine housing inspection revealed several safety and security compliance issues, including requirements for building identification numbers, fire extinguishers, gas meter instructions, and security features. These violations were all promptly addressed and abated by September 20, 2006. The building's maintenance history shows attention to safety systems, with permits for fire alarm testing and garage improvements. Recent 311 calls related to the property (from 2021-2024) primarily involve external issues such as scooter placement, parking violations, and sewer vent problems, with one open sewer issue from September 2021. The building's documented history shows proper attention to safety systems and prompt resolution of identified violations, though the recent sewer issues may warrant monitoring.

Risk rating

How 426-430 Greenwich 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.

Neighborhood percentile

Out of 684 buildings in this neighborhood, 96 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.

Estimated permit spend (past 7 years)

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

Building permits, owner's portfolio

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

12-Month severity forecast
No violation 79.4%
Moderate concern 10.6%
Severe concern 10.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
