Initial analysis

The property at 406-410 Green Street in Telegraph Hill is a three-unit, three-story multi-family residential building constructed in 1907, currently owned by the Ravikumar Guo Living Trust. This historic building has undergone several significant renovations, most notably in 2008 when major improvements were completed at a cost of $80,000, including kitchen and bathroom remodels, plumbing and electrical work, flooring updates, and window replacements across multiple units. Additional substantial work was performed in 2007-2008 including comprehensive updates to electrical systems with the installation of 200 amps main service with 4 meters and panels, complete bathroom and kitchen overhauls in all units, and the replacement of furnaces and water heaters.

The building experienced multiple violations and complaints in 2005-2008, including issues with wood stairs, smoke detectors, emergency exits, and unauthorized work without proper permits. These violations were ultimately resolved, though some concerns related to seismic upgrades and plumbing work were noted during inspections. The most recent major infrastructure work was performed in 2020, including a sewer trap replacement and section of sewer lateral work. The property has had several 311 calls in recent years primarily related to street maintenance and parking issues, though no significant building safety concerns have been reported since 2008. A brief fire incident involving a contained cooking fire was recorded with no civilian injuries. The building's recent history has been relatively quiet in terms of major repairs or violations, with the most significant recent work being routine maintenance and infrastructure updates.

Risk rating

How 406-410 Green 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, 287 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.

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

12-Month severity forecast
No violation 75.9%
Moderate concern 16.3%
Severe concern 7.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
