Initial analysis

1575 Filbert Street is a 2-story multi-family residential building constructed in 1923, containing 9 units and currently owned by Woo Family Trust. The property has undergone several significant improvements over the years, most notably completing a mandatory soft story retrofit in 2017 at a cost of $70,000, with the final Certificate of Final Completion issued. The building received a new roof in 2019 ($9,500) and has maintained regular upkeep through various street space permits and other minor improvements. Several building violations were documented in 2004 regarding gas utility shutoff tools, stair repairs, and signage requirements, all of which were abated by March 2004. More recent fire safety inspections in 2021/2023 identified sprinkler system and alarm issues, with most being marked as "Condition Corrected" or "No Merit."

The building's history includes some concerning incidents, such as complaints in 1998 about a collapsed bedroom ceiling and leaking plumbing pipes, and in 2008 regarding damaged ceilings. There have also been multiple recent issues with vehicles blocking driveways along Filbert Street, with several citations issued between 2024-2025. The property was subject to investigation for illegal short-term rental activities in 2023, though ultimately no penalties were levied as the listing was removed. Historical records show past concerns about building code compliance, including an expired vinyl siding installation permit from 1998 and a 1985 permit related to bringing the building into code. More recently, a 2019 complaint regarding failure to comply with Soft Story Tier III requirements resulted in a resolution by 2022, and regular monitoring fees were addressed. The building's fire safety systems have received periodic attention, with multiple inspections noting various issues with systems that were generally resolved promptly, such as an alarm system incident in December 2021 which was marked as having "No Merit."

Risk rating

How 1575 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
