AI summary

The 9-unit multi-family residential building at 852-858 Filbert Street in Russian Hill, owned by Quan-filbert Family Lp, is a 3-story structure built in 1908 that has undergone several significant maintenance and safety improvements over the years. Most notably, the building has completed its mandatory soft-story retrofit (per San Francisco Building Code) with work valued at $82,000 in 2017, receiving its Certificate of Final Completion. Recent maintenance includes repairs to 10 siding panels in 2022 (cost: $2,000) following complaints about falling siding that posed a safety hazard, house trap replacement in 2020, and furnace replacement in 2019. The building has also received attention to various maintenance issues over the years, including reroofing projects in 2015 and 2001, and repairs to address dry rot in 2000.

The property has experienced several notable challenges, particularly in the early 2000s, when it faced multiple violations related to water damage, fire safety, security, and maintenance issues in 2001. These violations were all abated by June 2001. More recent concerns have included fire safety inspections showing issues with extinguishers (most recently in 2023), and a violation in 2020 regarding sprinkler testing and maintenance that was subsequently abated. The building has also experienced periodic infrastructure issues, including water heater problems in 2005, heating system failures in 2011, and lead paint concerns in 2013. Regular maintenance and infrastructure upgrades suggest ongoing attention to building safety and habitability, though the property has experienced periodic challenges with various systems and building components over its history.

Risk rating

How 852-858 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
11th percentile

Out of 1133 buildings in this neighborhood, 1008 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

12-Month severity forecast
No violation 8.7%
Moderate concern 19.3%
Severe concern 72.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
