Initial analysis

The two-story, four-unit multi-family residential building at 251 Collins Street in the Lone Mountain neighborhood, owned by Dhm Ii Lp and constructed in 1968, has documented several significant maintenance and safety events over its history. Most notably, in March 2022, the property was the subject of weather protection violation complaints that persisted through multiple notices between April and May 2022, and were eventually abated by July 29, 2022. These violations were particularly concerning as one complaint specifically mentioned potential lead dust migration due to exterior chipping, which was filed by a neighboring property owner. The building underwent reroofing work in 2006, representing a significant maintenance investment of $9,000.

Earlier history shows a cluster of safety-related violations in 2004, which were all addressed by July 29, 2022, despite being filed as early as February 25, 2004. These violations included issues with emergency exiting, fire extinguisher maintenance, smoke detector installation, and combustible storage concerns, indicating a period of notable safety compliance challenges. The building's inspection history dates back to 1999, with routine inspections conducted in 1999, 2004, and 2022. More recent activity includes three 311 calls between 2020 and 2024, though these were primarily unrelated to building conditions - including a parking enforcement issue and reports of hazardous materials on public property that were promptly resolved by city services.

Risk rating

How 251 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
44th percentile

Out of 519 buildings in this neighborhood, 291 are predicted to be safer.
