Initial analysis

The three-unit, three-story apartment building at 15 Sonoma Street in Telegraph Hill, owned by Sun Keng & Connie Chan Revo, has experienced several noteworthy events since its construction in 1907. Most significantly, in July 2015, the building faced multiple housing code violations including mold/mildew on floors, a malfunctioning refrigerator, lighting issues, a problematic door latch, and problems requiring compliance affidavits - all of which were resolved by September 2015. A routine fire safety inspection in 2005 revealed several concerns including expired fire extinguishers in public areas and issues with the fire escape ladder, requiring a follow-up inspection before being resolved. The building's alarm system also came under scrutiny in December 2021, resulting in a violation that was subsequently abated. While the building has had some infrastructure challenges, these have generally been addressed through appropriate channels.

The property has been subject to regular housing inspections, with records dating back to 2001 showing consistent oversight by Housing Inspection Services. Recent external infrastructure issues near the building have included various public works matters such as pavement defects (2021), flooding incidents (2019), and several street cleaning requests. The building's maintenance history suggests that while there have been periodic issues requiring attention, particularly regarding building systems and fire safety equipment, these have been addressed through the appropriate regulatory processes. The most recent documented building violation involving the alarm system was resolved within a week of being issued, indicating responsive management to regulatory requirements.

Risk rating

How 15 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.
