Initial analysis

The Tam Family Trust owns this 2-story, 3-unit multi-family residential building located at 2127-2131 Jones Street in Russian Hill, which was constructed in 1928. The property has undergone several significant improvements over the years, with the most recent major renovation taking place in 2019, involving comprehensive updates to the third-floor unit including kitchen remodeling, bathroom relocations, addition of three full bathrooms, and extensive electrical work including new lighting, switches, receptacles, fans, and smoke detectors. This renovation, valued at approximately $79,000, addressed both aesthetic and safety features. The building's safety infrastructure received attention in 1985 with the installation of fire sprinkler systems in the basement, though there was a cluster of building violations recorded in June 2006 that required attention, including issues with wooden stairs, fire extinguishers, and gas meter instructions, all of which were promptly abated by August 2006. Three routine housing inspections were conducted between 2001 and 2006, with all matters being addressed and closed. The property has maintained an active maintenance schedule, as evidenced by the 2019 permits for kitchen and bathroom work, though one central heater change permit from July 2019 is recorded as expired. Prior to the window replacement permits from 1998, the building's maintenance history shows a consistent pattern of addressing both routine and significant maintenance needs, contributing to the building's current good standing.

Risk rating

How 2127-2131 Jones 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.
