Initial analysis

The two-unit, two-story multi-family residential building at 1455 Silver Avenue in the Portola neighborhood, owned by Donitila & Eva Cartegena Tr, has a notable history dating back to its 1991 demolition of a previous structure and subsequent 1997 construction. The most significant recent building permit was a $12,000 reroofing project completed in 2015, while several earlier permits from the 1990s involved various administrative renewals and modifications, including the removal of an iron balcony in 1998.

The property has ongoing concerns related to an unauthorized dwelling unit, with multiple building violations filed in April 2003 regarding an illegal second kitchen installation in a ground floor room, though records indicate attempts to resolve this situation through various permits. More recent issues have primarily involved exterior maintenance matters, with several 311 calls in 2024 regarding street cleaning, garbage, and graffiti around the property. The building's documented history shows regular maintenance activity, including the recent roof work, but the persistent nature of the 2003 violation and the frequency of street-related service calls suggest ongoing neighborhood challenges, particularly regarding parking and public space maintenance.

Risk rating

How 1455 Silver Ave'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.
