Initial analysis

The property at 2830-2842 Diamond Street is an 8-unit multi-family residential building with commercial space, constructed in 1925 and currently owned by Hayes Bypass Trust. The two-story structure has undergone several significant renovations and improvements over the past decades, with the most recent modifications focused on ADA compliance and security upgrades. In 2023, permits were issued for hardware improvements and power door operators at both restaurant and gym entrances, following earlier compliance work in 2020 that included electrical upgrades and kitchen refinishing. A notable change of use occurred in 2007 when the ground floor transitioned from a self-service to a full-service pizzeria.

The building's maintenance history shows regular upkeep, including a complete reroofing project in 2016 and significant interior renovations in 2006-2020, such as floor replacements and electrical system upgrades. However, there were several compliance issues that required attention, particularly in 2009-2020 when violations related to fire safety, handrails, and unauthorized modifications were recorded and subsequently abated. A recent complaint from January 2024 noted graffiti on the parklet, and there have been recurring reports of garbage and debris issues in the surrounding area throughout 2024, though these are primarily external to the building itself.

Risk rating

How 2830-2842 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.
