Initial analysis

This two-unit multi-family residential building, located at 2809-2811 24th Street in the Inner Mission, dates back to 1900 and is owned by Xinwei Zhou. The building has undergone several significant modifications over the past two decades, with the most recent notable incident occurring in late 2022 when a washing machine malfunction caused water damage to multiple rooms, leading to delayed repairs and resident dissatisfaction. In 2014, substantial renovations were completed including converting one bedroom into two on the second floor, along with electrical and insulation upgrades. The property has a history of commercial use, with a successful conversion from art gallery to restaurant in 2008, which involved extensive renovations including new plumbing and electrical systems, though there were subsequent complaints about unauthorized changes to the projecting sign in 2022.

The building's maintenance record shows a mix of completed and withdrawn permits, including a 2009 cancelled permit for rear expansion and several older permits related to kitchen and deck repairs. More recent issues have included a 2019 complaint about roof leakage and mold, as well as a 2006 complaint regarding unauthorized unit modifications and deck construction. The property has been subject to multiple 311 calls over the past year, primarily relating to graffiti removal and sidewalk maintenance, though many of these were related to exterior public spaces rather than the building itself. While the building's permit history shows regular maintenance and improvement work, the recent water damage incident and ongoing concerns about repair timelines suggest some challenges with prompt maintenance response.

Risk rating

How 2809-2811 24Th 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.
