Initial analysis

The property at 56-58 Diamond Street is a two-unit, two-story multi-family residential building located in the Eureka Valley/Dolores Heights neighborhood, constructed in 1900 and currently owned by Dulce Maria Arguelles Lvg T. The building has undergone several significant maintenance and compliance improvements over the years, with the most substantial work occurring in 2011 to address the findings of physical inspection report CC-5850. This work included electrical and plumbing updates in common areas and bathrooms of both units, and the investigation of these compliance issues revealed previous unauthorized modifications, including a deck expansion in 2006 and furnace installation in 2004, though these complaints were subsequently resolved.

The building's documented improvements include a 2006 permitted replacement of the rear second means of egress and deck for the second unit, and a 1998 foundation reinforcement project that included anchoring sill plates and re-pointing brick foundations. Recent maintenance efforts and urban service issues have been relatively minor and mostly external, including periodic sidewalk cleaning and parking enforcement incidents in 2023-2024, as well as a weed and grass complaint in 2015 that was promptly corrected. The property underwent a successful 2-unit residential condo conversion process, with all necessary planning reviews being approved. While there have been various service calls and complaints associated with the property over the years, most have been routine urban maintenance issues not directly related to the building's condition or management.

Risk rating

How 56-58 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.
