Initial analysis

The three-story multi-family residential building at 1811-1819 Filbert Street in Cow Hollow was constructed in 1907 and contains 7 units, including a commercial space, owned by Gerald Carignani S F Prpt R. The property has undergone several significant improvements in recent years, with the most recent work being a kitchen remodel in 2021 costing $50,000, including cabinet and appliance replacements, accompanied by electrical rewiring and plumbing work. In 2020, the building underwent important safety upgrades including the replacement of seven Federal Pacific electrical panels per insurance requirements. Earlier renovations include a substantial 2015-2016 kitchen and bathroom upgrade which involved removing a wall between the kitchen and dining room, requiring new structural support, as well as electrical work for new lighting and a 60-amp subpanel installation.

The building's history includes four routine housing inspections between 1999 and 2006, all of which were completed with no noted ongoing issues. A building complaint was filed in January 2021 regarding unpermitted work and noise, though this case is currently listed as not active. More recently, from 2023 to present, there has been a concerning pattern of incidents requiring street and sidewalk cleaning, including multiple reports of garbage, debris, and abandoned furniture. Four such incidents were recorded between November 2023 and June 2024, with some cases being marked as resolved. The property has also generated complaints regarding graffiti and waste on public areas around the building during this period. A fire incident was recorded at the property with unintentional ignition but no civilian injuries were reported.

Risk rating

How 1811-1819 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.
