Initial analysis

The property at 144 Winfield Street in Bernal Heights is a two-unit, single-story multi-family residential building constructed in 1908, currently owned by the Ackerman 1995 Living Trust. The building has undergone a few significant renovations over its lifetime, most notably a completed horizontal addition in 1998, for which a permit was renewed in 1999. Earlier improvements from 1986 included updates to the flue system, kitchen cabinets, and interior repairs and painting, though these permits are now expired.

Recent activity around the property has primarily involved public infrastructure and parking issues. There are currently several open or recently closed cases regarding parking enforcement and tree maintenance. Most notably, there is an open case from February 2024 regarding tree roots damaging the sidewalk, and a recently reported blocked sidewalk issue from December 2024. The area has experienced recurring problems with abandoned vehicles, with multiple reports between 2021 and 2024, though most were resolved promptly, either through the vehicles being removed or the situation resolving itself. A tree maintenance issue from December 2021 involving a hanging limb was successfully resolved. While the building itself has not had any major reported issues or violations in recent years, the surrounding area has experienced ongoing parking and tree-related concerns that may impact resident access and maintenance.

Risk rating

How 144 Winfield 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.
