Initial analysis

The property at 3300-3308 26th Street in San Francisco's Inner Mission neighborhood is a two-story, 6-unit multi-family residential building with a ground-floor commercial space, constructed in 1868 and currently owned by Kelly Sau Ming Yeung. The building's recent history (2023-2024) shows significant ongoing maintenance issues, particularly around building safety and habitability, with multiple violations issued in 2017 that remained active through 2023-2024. These violations include problems with security (hollow core doors), plumbing systems (toilet repair), interior surfaces (damaged ceilings), and heating/ventilation systems. More recent complaints from December 2024 indicate an active complaint about vacant space break-ins and non-code compliant entrance steps. The building has undergone various repairs and improvements, including a sewer replacement in 2019 ($18,500) and repair work on stairs and deck systems, though issues with garbage management and pest control have been persistent concerns, particularly during 2021-2024.

The property has experienced several notable incidents and regulatory actions, including a fire-related incident in 1988 (cooking fire, confined to container), multiple building permit modifications, and a period of controversy regarding the ground-floor laundromat's conversion to retail space without proper permits in 2021. Recent building permits demonstrate ongoing maintenance work, including compliance with various safety requirements in 2023. The building's historical records show consistent attention to structural maintenance, with various repairs to stairs, deck guardrails, and roofing over the years. However, the pattern of violations and complaints suggests ongoing challenges with building maintenance and habitability standards, particularly in relation to plumbing, security, and pest control issues.

Risk rating

How 3300-3308 26Th 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.
