Initial analysis

The 14-unit, 4-story apartment building at 2227-2233 Filbert Street, owned by Cardinale Living Trust, has experienced several significant safety and maintenance issues in recent years. Most notably, there have been recurring gas safety concerns in early 2024, with multiple complaints about a water heater installed without proper permits, leading to dangerous natural gas smells that required emergency responses from PG&E and firefighters. A plumbing violation issued in February 2024 regarding improperly installed DWV for a new laundry location and water heater installation was finally abated in March 2024. The building's current active issue as of 2023 involves concerns about mandatory soft-story retrofit compliance, and there have been several historical fire safety violations related to egress obstruction, combustible storage, and fire escape maintenance from 2000-2005.

The building has undergone various improvements over the years, including window replacements in 2019, bathroom and kitchen remodels in 2006, and electrical upgrades such as a new panel installation in 2011. However, several permits from the 1990s are listed as expired, including reroofing work from 1995 and front stair repairs from 1991. The property has experienced multiple safety system activations, including smoke detector activations, a gas leak incident, and various false alarms, though no civilian injuries have been reported in any incidents. Recent complaints have also involved routine issues such as sidewalk cleanliness and parking enforcement matters, though these are less critical than the building's structural and safety concerns.

Risk rating

How 2227-2233 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
