Initial analysis

The two-unit residential building at 439-441 Filbert Street in Telegraph Hill, owned by Robert J Toy, is a two-story flats and duplex structure constructed in 1907. The building's maintenance record shows several significant events, with the most recent major work being a complete reroofing project in May 2018 that cost $9,900 and was successfully completed. In November 2013, there were two related incidents: a plumbing repair to the housetrap system was completed, and a street space permit was issued.

The property has experienced some infrastructure challenges in its vicinity, including a sidewalk defect reported in March 2017 involving a collapsed section with a damaged vault cover, which was subsequently resolved. Additionally, there was a street lighting issue in June 2012 with a burnt-out light on an unknown pole, though this was fixed by May 2013. The building's documented history suggests regular maintenance attention to essential systems, with no recent safety incidents or unresolved complaints reported in the available data. The most recent building improvement, the 2018 reroofing, represents the latest significant upkeep performed on the property.

Risk rating

How 439-441 Filbert 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
69th percentile

Out of 684 buildings in this neighborhood, 212 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.
