Initial analysis

The property at 91 Bennington Street in Bernal Heights is a one-story multi-family residential building constructed in 1904, containing two units and featuring a flat & store configuration (4 units or less) under the ownership of Kate K Rosenberger. The building has undergone several significant modifications over the past two decades, including a 2014 renovation that added three sinks with associated plumbing work (completed at a cost of $1,000), and substantial accessibility improvements in 2004-2006 that included modifications to interior walls, new accessible entrances, and replacement of a wood frame floor with a concrete slab in the retail space (total costs approximately $37,000). The electrical systems received attention in 2017 with a panel relocation and additional circuits, and earlier upgrades in 2006-2005 included the installation of lighting, switches, receptacles, and an underground conversion.

The building has experienced some safety concerns, including multiple fire code violations documented in October 2021. More recently, there have been several parking-related issues in the vicinity, with numerous 311 calls between 2023-2024 regarding abandoned vehicles and illegal parking, though these do not directly affect the building's condition or safety. A mandatory dwelling unit merger was proposed, seeking to reduce a two-bedroom unit to one-bedroom status, though it was noted that the units were not comparable in size. The property has also been involved in commercial activities related to The Epicurean Trader specialty grocery and deli counter at a nearby address on Cortland Avenue, with related permits and approvals documented through the Planning Department.

Risk rating

How 91 Bennington 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.
