Initial analysis

This three-unit, three-story flat located in Cow Hollow is undergoing significant safety and modernization improvements. Recent work includes the installation of a new roof deck (326 SF), comprehensive window replacements on the front facade, and the addition of a detached ADU unit with associated fire safety upgrades including a new sprinkler system and a 2-hour rated exit passageway. The building's safety systems have been substantially enhanced, with recent permits showing the installation of new sprinklers throughout the building and ADU, as well as the installation of a new 400-amp electrical service with four unit meters. The property has also seen major interior improvements, including comprehensive bathroom and kitchen remodels across multiple units, and the installation of new tankless water heaters.

The building's recent history shows proactive maintenance and upgrades, with attention to both safety and comfort. This includes the replacement of windows due to leakage and mold concerns, installation of new furnaces, and the addition of a mini-split heat pump for the ADU. Historical violations from 2005 related to self-closing doors, stair repairs, and permit requirements were resolved by 2009. Two complaints were filed in July 2022 regarding early construction work, and there has been one routine housing inspection recorded from 2000. The property has also experienced several parking-related issues in recent years, with multiple complaints about blocked driveways, though these are not directly related to the building's condition or management. A single fire-related incident involving a hazardous condition was recorded, but no civilian injuries were reported.

Risk rating

How 1742-1746 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.
