Initial analysis

The two-unit residential building at 46 Silliman Street in Portola, owned by Henry & Angelita Domingo Tr, has been standing since 1977 and is classified as a Flats & Duplex structure. The property has experienced several maintenance and safety issues over the years, with the most recent concerns centering around fire safety systems. In 2024, multiple fire safety complaints were filed regarding sprinkler systems and fire extinguishers, though the sprinkler complaint was ultimately deemed to have "No Merit" while the extinguisher issue was resolved by mid-October 2024. Previous fire safety violations include problems with extinguishers in 2022 (violation issued) and 2021, and issues with exit maintenance in late 2021, all of which were corrected.

The building's infrastructure maintenance history includes a significant emergency repair in December 2020 involving a $15,000 garage door replacement and associated wall repairs. An electrical permit from 2006 for a garage door opener installation was marked as expired. A notable historical issue occurred in 2001-2002 involving a complaint about shared power usage between units with one main breaker, which was investigated by the Electrical Inspection Division. More recent records from early 2025 show ongoing concerns with garbage and debris management around the property, particularly during January 2025, along with a reported instance of graffiti. A missing side sewer vent cover was reported in January 2025, though this was determined to be a duplicate complaint. The building's fire safety history shows a pattern of required corrections across various systems, including alarms, which were addressed between 2007 and 2024.

Risk rating

How 46 Silliman 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.
