Initial analysis

The property at 1866-1868 Filbert Street is a two-unit, two-story multi-family residential building constructed in 1925, currently owned by the Mariani Patricia B Family Trust and located in the Cow Hollow neighborhood. The building has undergone several significant improvements over the past few decades, with the most substantial recent renovation occurring in 2016, when comprehensive updates were made to unit 1868 including a kitchen remodel (with new cabinets, countertop, sink, faucet, and dishwasher), along with extensive electrical upgrades that featured a new 200-amp overhead service, two 100-amp panels, new circuits for various appliances, and bathroom lighting improvements. Prior to this, the building received a new roof in 2014 (following a previous roofing permit from 1995), and has had various maintenance work completed including exterior back stair repairs in 1990 and aluminum window installations in 1983.

The property has experienced some external issues typical of urban environments, with four 311 calls related to street conditions between 2021 and 2024, including reports of waste, loose garbage, and hazardous materials (glass) on or near the property. There were also two reports of abandoned vehicles near the property in late 2016, though both were resolved with the vehicles leaving the area. A driveway blocking incident was reported and resolved in April 2024. While these external incidents have been resolved, they represent the most recent interactions with the city's services related to this property. The building's maintenance record shows regular upkeep and modernization efforts by the owners, particularly in the past decade, with no recorded building code violations or safety concerns in the available data.

Risk rating

How 1866-1868 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.
