Initial analysis

The property at 2850-2852 Folsom Street is a two-unit, two-story multi-family residential building constructed in 1900, currently owned by Black Cat 17 LLC. The building has undergone several significant improvements and maintenance work over the years, with the most notable recent events including two instances of graffiti on or near the building in 2023-2024 (one of which remains open), and multiple parking enforcement issues involving blocked driveways, with citations issued in several cases between 2022-2024. The building's systems have received substantial upgrades, including the installation of a solar electric power system in 2004 valued at $17,000, the replacement of windows in 2008-2009 (custom and vinyl), and various roofing projects in 2000 and 2004. Structural improvements were made in 2004 with the replacement of an exterior staircase due to dry rot, representing a significant investment of $18,000. The building's electrical infrastructure has also been upgraded, including underground service improvements completed in 2004.

The property's maintenance record shows regular upkeep, with multiple window replacements and roofing work documented through building permits. The building has experienced recurring issues with vehicles blocking driveways, which has required parking enforcement intervention on numerous occasions. The recent graffiti incidents and the remaining open case from 2023-2024 may require attention, though they do not appear to indicate any structural or safety concerns. The property's solar panel installation from 2004 suggests an early adoption of sustainable energy practices, though the system's current condition is not documented in the available records.

Risk rating

How 2850-2852 Folsom 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.
