Initial analysis

The two-story multi-family residential building at 971-981 Filbert Street in Russian Hill, owned by Choy Stanford S H & Virginia, was constructed in 1915 and contains 6 units. The property has undergone several significant renovations and maintenance work over the past two decades, with the most recent major project being a $24,800 reroofing of the entire building in 2020. Other notable improvements include a comprehensive bathroom remodel and stair replacement in 2010, a complete plumbing upgrade including sewer line replacement and copper repiping in 2010, and the installation of new electrical fixtures and safety equipment (smoke detectors) in 2010. The building previously experienced several fire safety compliance issues in 2005, including problems with fire escape stairs, fire extinguishers, and combustible materials storage, though these were all resolved by 2021.

The property had a recurring issue with building address identification, most recently documented in 2020, where improper street numbering caused emergency response difficulties. This issue had been previously noted in 1996, 2005, and 2020, with the most recent complaint being abated in 2021. While there was one recorded fire incident involving smoke odor, no civilian injuries were reported. The building's infrastructure has been regularly maintained, as evidenced by the multiple roofing projects (2009 and 2020), stair replacements, and significant plumbing upgrades including five water heaters and comprehensive gas line improvements. Recent 311 calls from 2023 to 2018 primarily concerned street cleaning and parking issues near the property, which are not directly related to building conditions. The property has maintained active compliance with building codes since the resolution of the 2005 violations, with the last known housing inspection-related complaints being resolved in 2021.

Risk rating

How 971-981 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.
