Initial analysis

240 Collins Street is a two-story, 6-unit multi-family residential building in the Lone Mountain neighborhood, built in 1964 and currently owned by Vera Winkler. The building has undergone several significant improvements over the years, most notably completing mandatory soft-story seismic upgrades in 2014 (Tier 3), reroofing projects in 2016 and 1999, and the installation of vinyl siding and window replacements in 2005 and 2008. In 2021, the building received important safety upgrades including a fire alarm upgrade with new smoke detectors and wireless communication systems, though there was a subsequent violation issued in June 2021 for alarm system maintenance that was later abated. The property experienced notable issues in 2019 with multiple violations related to mold, interior surfaces, and safety equipment, all of which were abated by July 2019.

Recent history (2022-2023) shows concerns about unpermitted construction work, with two complaints filed in February 2022 regarding loud construction noises and lack of permits, and a more recent complaint in September 2023 about alleged unauthorized work including electrical and demolition activities. There have also been concerns about fire safety, including a 2021 complaint about children playing near a hatch or exit and a 2019 complaint regarding a locked fire escape door producing mold issues in Unit 4. The property has experienced recurring issues with driveway blocking, as evidenced by numerous parking enforcement citations between August 2024 and December 2024. While many past violations and complaints have been resolved, the building's recent history of construction-related complaints and parking enforcement issues suggests ongoing management challenges.

Risk rating

How 240 Collins 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

Out of 519 buildings in this neighborhood, 509 are predicted to be safer.
