Initial analysis

The two-unit multi-family residential building at 28-30 Sonoma Street in Telegraph Hill, owned by the Louie & Dang Family Trust, is a two-story structure built in 1906. The property has undergone several significant improvements over the years, with the most substantial being a major interior renovation initiated in 2022 costing $615,000, which involved demolishing and replacing all interior partitions and floors throughout the building, along with updates to street-facing windows and roof deck improvements. Prior to this, in 2016, the building received a new roof ($5,800) and underwent modifications to its roof deck access, including the installation of new stairs at the existing interior stairway to address code compliance issues with non-conforming rear stairs; this work was part of a larger project previously associated with the neighboring property at 1327-1329 Kearny Street.

The building's maintenance and compliance history shows attention to safety and modernization, with no recorded safety violations or complaints in recent years. The only incident on record was a street cleaning issue in 2014 that was promptly resolved with no waste found. The recent extensive renovations and improvements suggest proactive management of the property, with no changes to the building's unit count or residential use proposed in the recent planning applications.

Risk rating

How 28-30 Sonoma 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.

Neighborhood percentile
83th percentile

Out of 684 buildings in this neighborhood, 116 are predicted to be safer.

12-Month severity forecast
