Initial analysis

The three-unit residential building at 427-429 Filbert Street, located in San Francisco's Telegraph Hill neighborhood, is a three-story flats and duplex structure built in 1922, currently owned by Sisko A Luopajarvi 1993 Fml. The building's recent history shows both maintenance work and some regulatory challenges; most notably, in 2011 there was a violation regarding an unpermitted roof deck construction that was reported in January and subsequently addressed by April of the same year with the legal replacement of exterior deck and railing costing $5,000. The building underwent significant maintenance work in 2008 with a $24,350 reroofing project. Earlier records from the late 1980s indicate safety improvements were made, including the installation of fire protection systems and a fire escape completed in 1988 following shop drawings submitted in 1987, with an additional one-story addition project initiated in 1986, though its permit ultimately expired. More recent maintenance issues included a missing side sewer vent cover in October 2017, which was resolved within a week, and one housing complaint in 2007 regarding a possible illegal unit that was investigated and closed within three months. The building's documented history shows regular maintenance and compliance efforts, with the most significant recent issue being the roof deck violation that required remediation to achieve compliance.

Risk rating

How 427-429 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
74th percentile

Out of 684 buildings in this neighborhood, 178 are predicted to be safer.
