Initial analysis

The two-unit residential building at 2789-2791 Diamond Street in Glen Park, owned by Jeffery & Diane Cerf since 2002, has undergone several significant maintenance and infrastructure updates since its construction in 1945. Most notably, in late 2019, serious safety concerns were documented regarding the garage dryer ventilation system, where a gas dryer was found venting into a plastic bin containing dirty water instead of outside, and an outdated furnace was located in proximity to this setup. Additionally, during this period, there was an incident involving a missing battery in a carbon monoxide detector that was subsequently addressed by the tenant. While the building's permits show regular maintenance activity, including a complete reroofing project in 2010 ($7,950) and multiple window replacements in the mid-2000s (including a $6,243 project in 2005 to replace 10 windows), the property's systems infrastructure has faced some challenges, including an expired house trap replacement permit from 2015. The building's exterior features have also required attention, with sidewalk issues reported in 2015, including one instance of collapsed sidewalk covering 100 square feet that was documented and resolved by the Department of Public Works.

Risk rating

How 2789-2791 Diamond 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.
