Initial analysis

The property at 415 Prentiss Street in Bernal Heights is a two-unit, two-story multi-family residential building constructed in 1927 and currently owned by Benjamin Wang. The building has undergone several significant improvements over the past decades, with the most recent major work being a water heater replacement in 2016 and a roof replacement in 2014 (cost: $7,000). Notable improvements between 2008-2009 included a kitchen remodel ($11,000) featuring new cabinets, electrical work, and plumbing updates, front steps and handrail repairs, and replacement of back wall siding with insulation. The building experienced a fire-related incident requiring joist removal and sheetrock repairs in 1988.

More recent concerns include ongoing infrastructure issues, particularly with the sidewalk, which has been documented as defective/collapsed in 2023 and 2021. A graffiti incident was reported on the sidewalk in 2022, though it was noted as non-offensive. The property has been the subject of multiple parking-related complaints between 2020-2024, with two recent abandoned vehicle cases in December 2024. A concerning complaint was filed in September 2007 regarding unpermitted jackhammering work affecting the driveway and passageway, though this was quickly abated. The surrounding area has seen various municipal service calls, including reports of illegal postings, pavement defects, and holiday waste removal, all of which were resolved through regular city services.

Risk rating

How 415 Prentiss 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 1276 buildings in this neighborhood, 434 are predicted to be safer.
