Initial analysis

The two-story multi-family residential building at 161-165 Cook Street in the Lone Mountain neighborhood, built in 1912, is a three-unit structure currently owned by Act Two Holding LLC. The property has undergone several significant improvements over its lifetime, with the most recent major work being stair repairs at the rear of the property completed in 2021, costing $4,500. Historical records show substantial structural improvements were made in 2000, including seismic upgrades with shear walls and a moment frame installation, followed by various deck and stair reconstructions in 2001. Other notable improvements include roofing work completed in 2009 and multiple interior remodels of bathrooms and kitchens in 1988-1989.

The property has experienced recurring tree root issues affecting the sidewalk, with reports in both March 2023 and October 2021, though one case from October 2022 was closed with no conditions found. A series of parking-related incidents has been documented between 2020 and 2024, with multiple cases of driveway blocking resulting in citations being issued to various vehicles, including instances involving a Chevy Camaro, a Hummer, and a Prius. The most recent complaint was logged in September 2024 regarding abandoned furniture on the street, which has since been resolved. The building appears to be well-maintained from a structural perspective, with regular upkeep demonstrated through the various permits and repairs documented over the years.

Risk rating

How 161-165 Cook 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.
