Initial analysis

The subject property at 5-11 28th Street is a three-story, 5-unit multi-family residential building constructed in 1913, currently owned by Claudia C. Kardzair. The building has undergone several significant improvements over the past two decades, most notably including sewer line repairs in 2013, rear stair replacements in 2005, and various restaurant-related modifications between 2002-2014. The restaurant space underwent multiple changes, with permits issued for installing equipment and infrastructure including a hood system, exhaust fan, grease trap, and gas lines, culminating in a 2014 change of use approval from limited restaurant to full restaurant status with a Type 41 ABC license.

The building has experienced typical urban challenges over the years, with documented routine housing inspections in 1996, 1999, and 2008, the latter revealing a fire safety issue that was promptly resolved within a month. More recently, the property area has faced several maintenance issues, including reported sewage backup (January 2023), graffiti removal (January 2023), and multiple street cleaning matters (most recent in December 2024). Urban forestry concerns have emerged in late 2024 regarding tree maintenance. The building's safety record is generally clean, with no reported fire incidents resulting in civilian injuries, though there have been documented non-building fires and vehicle accidents in the vicinity. The property has complied with various municipal requirements throughout its history, including completing necessary repairs and addressing safety violations in a timely manner.

Risk rating

How 5-11 28Th 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.
