Initial analysis

The 6-unit multi-family residential building at 31-41 28th Street in Noe Valley, owned by Sur-miao & Mei-mei Yeh Tung, was constructed in 1884 and consists of 1 story. The property has experienced several maintenance issues and violations over the past 25 years, with the most recent being a concerning mold problem in July 2023, primarily affecting the kitchen area, along with water damage and a soft floor in the restroom. The building has a history of fire-related incidents, including fire damage repairs in 2000 and a fire-related violation in 2003, and there was a significant roof replacement project completed in 2004 costing $8,500. More recently, in October 2023, there were complaints about construction debris and a trailer obstructing the roadway, which was validated by multiple 311 calls regarding parking violations and construction equipment. The building has undergone some accepted improvements, such as wood floor refinishing and bathtub refinishing completed in 2022, and the installation of 3 floor drains in October 2023.

Historical records show that in March 2003, there were multiple violations related to safety concerns, including storage in the gas meter box, broken windows, and various fire safety issues, though these were all abated by October 2003. The property underwent a routine inspection of common areas in 2008, and there was a smoke inhalation complaint in September 2018. A withdrawn permit from 2014 intended to address soft-story conditions through shear wall and foundation installation suggests previous structural concerns. Recent plumbing work completed in October 2023 indicates ongoing maintenance activity at the property. The building has had various 311 calls for street and sidewalk issues in the vicinity, though these are primarily external to the building itself, including requests for parking enforcement and street cleaning services.

Risk rating

How 31-41 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.
